Brushless Revo + A123 and ICE

[zeropointbug]

Purplefade: The A123's have a max charge voltage of 3.8volts, and 3.6v standard, so anywhere in that range will give full charge. Like you said, the A123's don't accept much charge at all after 3.6v, so charging them is fairly straight forward.

To answer your question, the only way to get a 100% charge with the A123's is to buy a switching mode power supply (lab type) that has the CC/CV function, most do though. I have a 5s2p setup for my truck and I am charging them using a BK PRECISION power supply (20volt/10Amp), it's very good quality, charges them in <30mins, and I can completely program it if I want to. It is ~$240 though, but can charge any battery type you hook up to it, and would most likely be your last.

-So I would either just stick with the Dapter+, or Dual...+, I am not sure if putting them on again will top them up though.

-Or solder on the proper balancer plug, and use A123's charger they sell.

-Or buy a good power supply with CC/CV programmable, very nice.
