 Oct 06, 2012, 04:51 PM Registered User I am considering purchasing the Icharger 206 or 306 and have a question. I will mainly be charging 3S batteries. Is there a current limit when charging with a 12 V power supply? My target is to have between 10A and 12A when charging 3S with a 12v power supply. Thanks!
 Oct 06, 2012, 05:09 PM RC Helicopter Pilot The limit is 1/2 the output of the rated full input (this case 24V). This is generally true for most chargers. Although some chargers require 26V - 30V input to get full output. Last edited by TheWoodCrafter; Oct 06, 2012 at 05:41 PM.

Both chargers are capable of charging 3S at 10-12A with 12V input. Charging 3S means that input and output current is more or less the same.

 Oct 06, 2012, 05:51 PM Registered User TheWoodCrafter is correct for the 306B but not for the 206B. The 206B has a maximum charge of 20A. This applies to the input as well as the output. Therefore at 12V input, 20A current, it is limited to approximately 240W charge. Still more than enough to do 3S at 10-12A.
 Oct 06, 2012, 06:02 PM That's a funny word 306B has a 50 amp limit for input and a 30 amp limit for output. It also has a 500 watt limit when input is 12 volts. It will never reach that limit on the input with 12 volts. It can reach the output limit though not on 3s packs.
 Oct 06, 2012, 06:25 PM Registered User Thanks folks. My current charger is rateds at 5A, but only does that with 120V input. On the 12V PS, it only does 3.5V and tired of 1S charging in the field. Bumping to 2-3S will be very nice.
 Oct 06, 2012, 07:00 PM Registered User I think I see a 306 coming my way in the near future...!
 Oct 06, 2012, 07:36 PM Registered User There is a graph in the manual for each icharger which shows the maximum output power for any input voltage, you can answer your question by reading the manual, which I'd always worth doing when investigating buying a new piece of equipment.

I had looked at the manuals of several other chargers to no avail for the info I sought, so did not even bother looking until after my question was answered. A good manual for a change!
 Oct 10, 2012, 06:59 AM Registered User I have a 106b that has a problem,where all my r/c stuff is 2s lipo the charger does it's job just fine however when balance charging my Zippy 5s cordless drill batt cell no4 reads very low and from storage voltage the charger goes into balancing eventually over 4 volts this cell will stabalize and the reading becomes acceptable.When it's in this stage of an imbalanced reading all of my testers read that cell as normal voltage that would be cheap buzzers to my EOS Sentry at the end of charge cycle the resting voltages are OK ,i am using my older acucell 6 on it where and the cell readings are normal all the way through the process for saftey, as my primary concern is this false reading will somehow entice the charger to do the wrong thing,has anyone seen this weird behaviour on a 106B.Thanks

When the drill is in use i run a buzzer and the cell voltages are coming down fairly close which says to me it's not the battery having a bad no 4 cell,quite perplexing this,i suppose my solution would be to use the Acucell6 on this battery and use the 106b for my r/c stuff
 Oct 11, 2012, 12:59 PM Old Dog learning new tricks~~ Ok I have a 306b charger and my question is--- when battery is fully charged the 306b shows the cells all at 4.20 each but then when I check with any other battery checker like even the nice futaba battery checker/balancer it will show the cells decending like cell 1 @ 4.20 cell 2 @ 4.19 and cell 3 @ 4.18 and that would be the best case usaully it's not even that close. Is that what others are seeing as well? How accurite is the charger? and is it real important to have all equal cells or at what point of seperation should you be concerned? Thanks Brad

iCharger 106B+
Today I charged a 6s 5000mAh at 2C = 10A and I think the banana connected melted. Should I be worried or just solder a new connector?
Thanks.
