Hi, can anyone give some feedback on performance?. What rate does it charge at, 0.5C, or 1C, 2C?, for 2200maH is it charging it at 1C (does it take ~ 1hour). Does it balance well?

My test shows that it changes a 3s 35c 2200mAh battery at only 1.2A (so about 2 hours to charge). I would not recommend this charger for any thing. Better to get the HobbyKing ECO6 50W 5A Balancer/Charger which is good.

Thanks, I bought one, it didn't work. Got a free replacement, that didn't work either. Both went in the bin.

anyone tell me if this can handle charging a li-ion battery?
 Ron 79 points
No li-ploy only (and not even any good for that!)

what do you do when you want to charge on a wall socket at home? does this need a separate cable for plugging the main leads?
 Desieve 120 points
Hi, Yes you need a separate cable. Often laptop power cables can work nicely, if its 11-18V DC and rated 4A or more. Similar to this product that HK sells, PRODUCT ID: HK15-5

i got this one with the hope that it will charge faster than the other model... Not at all..it hangs about 3-4 hours to charge a 2200 mah 3s lipo (new lipo) Charging current is far under 4 Amps..i do not know how it controls the process automaticly, but each time charges 3-4 hours (1500 mah - 2200 mah 3s lipos, tried it on few batteries)

Hi Nukii. I just received one, and I think I am having the same problem. I tried charging a 1000maH battery, measured the approximate charge current of 0.8amps, it seemed to charge it after about 50 minutes, but then spent 1 hour trying to balance, I stopped it after waiting this long. I then tried a 2200maH battery and measured 1.1amps charge current, I gave it 15mins but it just stayed at 1.1amp. Could be a complete waste of money. Did you get a replacement?
 nukii 66 points
yes i did, but my charger was absolutely hopeless..
 Desieve 120 points
Hi nukii, so you got a replacement, did your replacement work?
 nukii 66 points
Better buy PRODUCT ID: 9331000001. I am much happier with it.. Yes it charges a bit slower but so far works reliable. I did not receive replacement for B4 Pro so i can not say much about it..

Great little charger that is idiot proof and prevents human error. Just plug in balance lead connect the main lead and the charger does the rest.

I bought 1 of these chargers and it did not work. I tried to charge a 3S 1000mah battery, it would charge it, but LEDs did not go orange when 90pcnt full as stated in manual, and then once battery was charged to 12.6v it stayed in balance mode for 40mins (1hr 45mins after starting charge), after this much time I turned it off. HK then sent me a replacement and the replacement charged 20pcnt faster but had the same faults. Both chargers going in the bin.
