So I want to use these in my baja for steering , wired together gets you the 2 cells? Wired in a series? do they need to be wired together for bal/chrg
Wired in series you'll get 4 cells 14,4 Volts. Wired parallel you'll get 2 cells 11400mAh If you want to charge/balance them at the same time you'll need to make adjustmenst to your balance connector, because it will only fit your 2 cell balance port. You'll need to change that and charge them connected in series to make your charger think it's a 4 cell. Better to charge them one at a time to be on the safe side.
I checked these parameters with my RS-550PF engine with 30A Speed Controller , these be great Voltage and Discharge , but Capacity no have 5700mAh maybe
5200mAh - 5300mAh
They will fit if you do what i did which is get the Battery height conversion kit from Durango after that its just puting in power packs for long runs of fun driving!! its worth it!! believe me!
These packs are a tight fit in a 1/10th scale car like a B44 or many touring cars, and the battery posts often need raising.
The Mini Inferno uses AA cells, so no chance!
One of my newly recieved cells is 0.7V or less. My charger told me low voltage and refuse to charge. Before I ask for refund, just wondering is it a problem with others? Thanks.
I also bot this pack and had the same prob. The problem occurs because the batt. was left uncharged for quite some time. TRY and put some juice into it by connecting i.e another charged pack on it and leave it for a min or so. Then reconnect it to your charger. It sud work
Charge just the one cell on a trickle charge of 0.1A or 0.2A (you may need to put it into NiMh mode to keep the charger happy). Keep a close eye on it, and preferably outside your house in case the worst happens.
Hi, Im new on this mater so: I have 2 kits of this bat. and a ECO 6-10 200w balancer from HK. I see here that the max. charge is 5A. What the Amp. value to balancing and discharge? In the quick charge and storage charge use the same Amp than in normal charge? Thanks
No, the max charge rate is 5C, it means you can charge the battery at five times it's capacity. In this case its 5,7A * 5 = 28,5A. Personally i think it's a bit steep, I charge at 10A when I'm in a hurry, 5,7A otherwise.
Most manufacturers recommend a maximum discharge rate of 1C, which means you can set the discharge value to 5A. The same goes to balancing mode, because the charger will reduce its current in order to balance properly.
Quick charge is usualy set to a higher rating than regular charge. I don't discharge my lipos, but I have it set to 1 amp just in case (I never have the need to discharge) For balancing this batery , I have it set to 2.2amps, but It is safe to balance at as high as 5amps.
5.7amps is about 1c on this battery, so if I had a charger capable, I would feel safe charging at 2c (11.4amps), but no more.
and c rating is dependent on battery capacity.
the lead supplied is for charging only. You need to make a lead to connect the from one cell to the - of the other cell. Then the remaining and - connect to the terminals on the esc. Hope that was clear
It's done in series. i.e. the two batteries are wired from one batts positive to the other's negative leaving a positive open on one batt and a negative open on the other. Those are your positive and negative leads to the ESC.
In the Product Config Table HK say that the Max Charge Rate is 5C. That can not be correct can it. It whould mean that I could charge the battery with 28.5 Amps. I guess that they mean 5A not 5C??
yes charge this only whit 5 amps becouse lipos lyfe is bether using only the amps that the batery said in this case maximum 5700 mah and for be shure 5 amps is bether.
They do mean 5C charge rate so 28.5 amps is correct but personaly I wouldn't do it that rate anyway. I'll stick with 1C unless I'm in a hurry but I'll probly not go over 2C even the.
5C for this batt means 5 x 5.7amps (or 1C). So yes it means 28.5 amps. However, good luck finding a charger capable of that feat!
While the batt's manufacturer claims they'll take it...it most certainly shortens the life of the batt. I'd still charge at 1C regardless of what the manufacturer says, unless you want to replace your batts more often than you HAVE to.
In theory, 5c would be correct, but I would definitely only trust this pack to charge at 2c max, I don't trust HK much, they seem to jack up the specs.
No, they are 1s/5700mAh each. You can use them individually as a 1s battery. They are ment to be connected serially as a pair in 1/10 buggys using this kind of battery setup...
They can be used individually. Each cell is a single 3.7v battery, making 2s when wired together in series. (not 4s as i think you are suggesting) Each cell is 5700mah but by wiring them together in series you only increase the voltage, not the capacity
Pretty sure there is more than one cell in each pack, probably 2 or 3 in parallel, hence why I believe that a saddle pack battery can never really be totally balanced. How are the parallel cells in one pack balanced? not many think about this. Anyway just my 2 cents.
No these are actually classified as 1 battery total. One with 1S1P and the other with 1S2P. Then wired in series to get to the 2S3P. One probably has 1S 2500mah and the other 1S 3200mah.
It is a set of two 1s3p batterys, with wires to connect them in series creating a 2s3p pack.
You can split them up and use them as large capacity 1s packs, but you can't split them up and have more 2s packs (safely/easily)
In each 1S here there are 3 1900mah cells in parallel. Which means that if you wire two of these 1S3P 5700mah packs in series, you'l get 2S3P 5700mah. Hope this helps explaining it!
I'm not sure what you mean but you connect your saddle pack battery like this when you charge www.link your left with the balance plug and /- connector, both go to the charger.

that blue wire should be attached to the black wire with bullet connectors on both ends
Hi friends, can I use this battery to power the rx and servos using a voltage regulator safely?. Will the higher discharge rate not damage the electronics/servos?. Thanks
No problems, the discharge rate is only a rating of how many amps the battery is capable of giving. Yor BEC, rx and servos will only use as much as they need...
Yes, higher discharge will not force out more current, but it will actually allow more current to be drawn if necessary. so it will actually improve performance.
Each of the packs consists of 3 cells in parallel. Those 2 packs are connected in serie with a wire bridge, giving you the whole saddle pack with a total of 6 cells
OK, call me dumb, but what the heck is a Saddle Pack?? - A box the battery is mounted in to protect it in a crash? - If so I know quite a few people who require them!! (But hey, even the BEST crashes from time to time).
They are used for touring cars having a center belt drive where they normally would have a 6 cell nimh pack but split into packs of 3 cells on each side of the chassis, to divide the weight out.
Hey dumb*) As Chris says its mostly used in track cars both touring cars and buggys. In this case it is in a "box" aka hardcase its not really for crash protecion, but its better if you drop them or stuff like that:)
Basically a saddle pack is the name for a stick pack that was cut in 2. That way, it will better fit 4WD cars, that usually have some axels or a drive belt through the middle of the car.
The pack sit around the axels/belt like a "saddle"
You really need to connect the 2 in serie to get the 7.4V...
if i were buying any lipos now i would buy saddle packs, as even if you are running something requiring a regular stick pack you can always place them end to end to give exactly the same dimensiona as a stick pack- much more versatile!!!
A lot of 4WD 1/10 Buggies require these packs. It means that you have to separate the 2 cells across the center shaft to be able to get enough battery in. Take a look at the Kyosho Lazer ZX5 FS
It's a "normal" pack divided in two, so you can use it in some chassis that require it either because of weight distribution, space restrictions or both. The box you're refering to is called Hardcase.
Looks like a straight replacement for most NiMh or NiCd saddle packs. I am using it in a Losi XX4. Massive capacity, so top marks for me. The only criticism I have is that it doesn't come with the right battery connector. The connector that mine came with was a standard bullet connector with balance wire. There is no third jumper wire to link the two packs and there is no place to put the balance wire. Not a big deal as most of us already have the wires hooked up on our speedy, but just keep this in mind when you order in case you need to order some extra wire and connectors.
My first zippy. Too much height(31mm) for my buggy, a Hotbodies Cyclone D4. Removed the case to get it fit. Measures 4mOhms/cell(DC,1s), good 15C cells, not likely 25C. Discharges 5460mAh to 3.0V/cell, 95pcnt of norminal. Zippy doesn't compare to Turnigy.
ces lipo passe nikel sur le chassis yokomo D-max , il suffi de mettre 4 vis plus longues il reste 3-4 mm en hauteur sous la platine carbone haute centrale plus1h de drift !!

5 thumbs up!
j ai achet ces accus pour le chassis D-max ils s integrent parfaitement , une fois les 4 vis remplaces par des plus longues pour etre bien cals , j ai mis un velcro (cot piquant) sur les 2 pates interne le lipo est nikel cal contre les pourtour et sa permet aux prise PK 4mm de ne pas frotter contre la platine carbne centrale haute pour utiliser le cable de charge fournis , remplacer le pk 2mm du fil bleu par 5 cm de cable et 2 pk 4mm
