This charger charges my 2s batteries fine, but on my larger Zippy (PRODUCT ID: ZC.4000.7S.25) 7s 4000 mAH batteries (I have 6 of these,tried with 3 different ones)the charger immediately stops on any LiPO function, and reads "Battery vol err, cell high vol". The voltage of these batteries, as delivered from HK reads about 27 volts on my multimeter. I have tried a couple different power supplies including my car battery on the charger.
The cell discharge, or balance, or storage functions all give the same error, and will not run.
HK tech on live chat had no answer, but that he always uses this same charger (Eco Eight product#HKB8Pro) to charge his 7 cell batteries.
Further, I did check to make sure all settings including LiPO type, and voltages (3.7 per LiPO) were correct) several times over.
On first connecting this charger, I did get a slight whiff of that 'magic smoke smell', but saw nothing, and found no excessive heat.
Do I have a defective charger, or did I miss something?
Hi P Scott, HK sells balance lead extensions, but unfortunately they only go as high as 6S (7-wire). I guess 8S chargers are not common enough to be worth making all the bits and pieces for them. If you just need one extension that will be used all the time, you could cut/splice/solder/shrink-tube wires into the lead on the balancing board to make it longer. Cheers, EA!
Hi lachlan, There won't be a problem as long as the power supply puts out a constant voltage between 11v-18v. The charger will only draw the wattage it needs and the power supply will only supply the wattage drawn by the charger. The 540W rating on the power supply is a max output rating. Cheers, EA!
200W PSU would be enough for a 150W charger. Unfortunately, there is no one here. You can buy stronger 350W PSU like PRODUCT ID: PS35. Of course, you can use a deep-cycle car battery or a converted PC power supply.
Hi , I have 2 packs of 4S2P li-ion battery with 2x 14,4/16,8 nominal voltage and 2x 70.56 Wh/4,9Ah max chharge current 3.2A ( each) max discarge currenet 6A
Can I use this charger to charge the two packs in parallel?
I have the 2 wires connected, principal and balance. It must be a charger problem for 2 days that I normally load but not now. I am using the same batteries. These batteries the charge with another charger and load without problems.
Hi Alfredo, These chargers are a bargain, but sometimes the QA at the factory isn't the best. The fact that your getting a "Connection Break" error tells me that the charger is trying to work, but it's not getting a reading from all of the cells when it runs thru the pre-charging checks. You need to closely examine all of the soldered connections on the balancing board and where the plug from the board goes into the charger. I'm willing to bet you have a bad solder joint in there somewhere. That happened to me with my ECO6-10 200W charger and it only took about 15 minutes to fix. Cheers, EA!
Unfortunately, there is another possibility. "Connection break" means that the main charging circuit has too high effective resistance. This may be ralated to the external parts (power supply, connectors, wires, charged battery) or internal components of the charger. If you can not find any failure outside, it might be the time to inspect the PCB of the charger. If you feel up to the task, you can open the charger case and look for burnt/cracked components like current sensors (U-shaped wires), power transistors (MOSFETs) or plain resistors.
Buy this product HobbyKing 150W 7A 8S ECO8 Bal / Dis / Cyc Charger w / acc. The order number is 2006214121. It turns out that with only 3 days of use does not work, when I try to load a lipo tells me "connection break". What can be the problem, as I do??
Hi Alfredo, Both leads from the LiPo must be connected because some of the charging/discharging is done thru the main lead and the balancing is done through the balancing plug, so the charger automatically checks both connections before it begins any charging operation. If both leads aren't connected it will give you a "Connection Break" error. Cheers, EA!
Hi Alfredo, I thought of one other possible reason for the problem. If you are saying that it worked correctly for a few days and now gives a "Connection Break" error, you need to check the balancing board to see if there is a bad connection there. Start with the socket you were using with your battery. Plug the LiPo into the board, but don't plug the board into the charger. Use a voltmeter to check for voltage at the plug for the charger. If you LiPo is 3S, you should get volt readings from the first 3 pairs of connectors on the plug. If you don't, check the board for a bad wire or solder joint. Cheers, EA!
*ElectricAussie: I was looking for a multifunction charger included has functions such as Hobby King Battery Medic System 6S but still affordable price. Could you help me to give information to me? I funds only $40
Hi Den Yusuf, The Accucel-6 50W charger (PRODUCT ID: ACC6) is a great little charger at a great price ($23). You can probably get it for under $40 all up including shipping to Indonesia. If you're going to be charging lots of high capacity LiPos (4000mah and up) you might want a higher output charger such as the HK ECO6-10 200W ($35), but it will cost you more than $40 with the shipping cost added. I own both of these chargers and they're both very good, but the Accucel-6 is my favorite. It's very high quality and very accurate. Cheers, EA!
Hi Den Yusuf, The Battery Medic acts as a cell checker/balancer, which this charger can do. What exactly are you wanting the charger to do that the Battery Medic does? Cheers, EA!
> ElectricAussie
Thank you very much. Both of the connection is required. did not know.
Why, if only code balance charger can charge only have. It was the first time the rapid charger.
It's shameful. .
and thank you to everyone.
Hi elichi, Both leads from the LiPo must be connected because some of the charging/discharging is done thru the main lead and the balancing is done through the balancing plug, so the charger automatically checks both connections before it begins any charging operation. Cheers, EA!
Hi eiichi, You must connect both leads from the LiPo to the charger. The balancing plug into the white socket on the balancing board and the main red/black lead into the 4mm red/black sockets on the charger. If your LiPo has the XT60 connector, use the cable that came with the charger. If not an XT60 connector then you need to get an adapter cable. Cheers, EA!
Thank you for the help so far, but my situation i a little different. I have a couple seperate household sized rechargeable NiMh D batteries for a lantern for example. I don't have any way to attach them to the charger as they stand. I wondered if there was an adapter or something along those lines that will allow me to put those Ds in then plug it into the charger for a faster charge than my energizer charger, which takes around 8-10 hours.
Hi HJ, You would need some sort of battery tray/holder that the D-cells go into with a lead to plug into the charger. Easy to find for AA/AAA cells, but tougher to find for D size. Have a look at ebay Item number: 180096655656. Something like that would work if you solder a lead onto the terminals of the tray. Cheers, EA!
I have this charger and it's great but I also have 10,000 mAh rechargeable NiMh D batteries and I was wondering if there is a way to charge them with this charger because they are capable of a quick 3 hour 4000mah charge?
Hi HJ86, There's a NiMH charging mode built into the charger. You just input the number of cells (in series) that you're charging and the charge rate and it will do it automatically. Cheers, EA!
Hi Roger, You should have received an adapter cable(s) with the charger. If not, go to the "Chargers and Accessories" menu above and select "Charge Leads" from the sub-menus. You'll find the one you need in there. Make sure it has 4mm banana plugs at one end and your LiPo main lead connector at the other. They're usually light enough that you can meet the minimum postage rate from HK. Cheers, EA!
Hi ElectricAussie,
Thanks for responding to my query.
I followed your instructions. I got a constant beeping with a 'Charger disconnected' message. Actually the charger is a ecosix not a HK8, but they seem very similar to look at.
Any ideas? Thanks, Roger
Hi Roger, The firmware for the ECO6 and ECO8 are basically identical, so it should make no difference. Are you sure the error is saying "Charger Disconnected" and not "Connection Break"? A connection break error is common if you don't have both leads from the LiPo plugged into the charger. The main lead (red/black) must be plugged into the red/black sockets next to the white balancing plug socket(s). The balancing plug must be firmly pushed into the correct socket. If this doesn't fix the problem, then you have a bad connection somewhere. I had this problem with my ECO6 200W and found a bad solder joint inside on the balancing plug board. The prices for gear on HK may be great, but the quality control is often dicey so these kinds of problems slip thru. Cheers, EA!
I am brand new to this. I bought a HKB8Pro charger. I connected my battery (li-Po) 4000 and calibrated the charger to 11.1 v as per instructions and dialled in 4amps. I have been told to expect the charger to show a reduced voltage as the battery gains charge. I have had it on charge for a total of 2 hours but no change and no charge. What am I doing wrong>
thanks, Roger
Hi Roger, It may be nothing more than how you're pushing (or not) the buttons. Here's the drill: Connect both the power lead and balance plug from LiPo. 1) Get the charger into LiPo mode. 2) Press Start, set Amps 3) Press Start, set # of cells 4) Press/hold Start until you hear 2 quick beeps, release Start, 5) Press start again to begin charging. Cheers, EA!
Hi Adejunior, Almost any charger can charge your 10,000mah LiPo, but usually not at the max possible rate. This charger has a max output amp rate of 7A, so if your LiPo is fully discharged it will take 10/7=85 minutes to charge the LiPo. Have a look at the ECO6-10 200W charger (PRODUCT ID: HKB610A). It charges at 10A and will charge your 10,000mah LiPo in 1 hour. Cheers, EA!
the HKB610A can, yes, but only if the battery is rated for charge rates that high. For example, standard charge rates of lipo batteries are 1 x capacity, (1c) so if you have a 10000mah battery it is safe to charge at 10000mah, or if you have a 5000mah battery that's capable of charging at 2c, or a 2500mah battery capable of charging at 4c, or a 1000mah battery capable of charging at 10c, any of these can be charged at 10000 mah. That said, I personally don't feel comfortable charging lipos at super high charge rates. I have the the 2s nano-tech 350mah 65-130c, which states an 8c max charge rate, (2800mah) but the most I've charged them at is 1500mah, (just over 4c) and although they have held up fine and never heat up, I'm still reluctant to charge any higher than that.
I recommend not going for a cheaper power supply as their amp ratings are not very honest, the moment you load the supply the voltage drops like a rock.
Dose this thing gone charge , them 7S 4000ma zippy compact , that come with two JST balance plugs ,one for 3S and one for 4S. hay while we at it ,is gone charge same zippy 8S ,that got two 4S JST plug !!!!

I bought a charger and balancer Eco Eight and I can not download any NiCd and NiMH, I put to download a particular battery amperes corresponding to it for example I click Start and 0.5A for processing soon after the display shows the beginning of unloading and showing 7.2A always, all batteries do not obey the lineup of amps I've programmed to dump it in a few seconds the unit apresenda the following message "Control Failure."

2 thumbs up!
"Control failure", I get the same message on my SECOND purchase (!!) = Charger is dead, is broke!! The instructions say to take it to service center ... I take the car and I come to China? This charger is an absolute crap! It is not possible for me to spend the money for the expedition from Honkkong, and return, at my expense! I paid to use, it not to spend more money every time (shipping Italy-Hong Kong $ 24!) without a your refund. Not Buy it and not sell, please! ! What a scandalous!

I got this charger about a week ago. It looks awesome but while charging its first 3 cell 1500 mah it (the charger)got so hot I couldn't touch it. Then after about 15 mins a big puff of that stinky electricle smoke flew out the the fan. lol Its not worth the powder to blow it to hell, oh well. I gotta say I'm having very good luck with the eco six though.

I purchased one of these chargers and it worked fine so I decided to order another 3 just like the first. The problem was one out of the three would not work. It would show different errors everytime I tried to use it even blowing the fuse on my power supply. I contacted Hobbyking and they said they would replace if I returned it to China even though they where shipped from the US. Shipping to China would be $39.00 to return a charger that cost $36.00. So I am stuch with one charger that is no good.
