This battery is way cheaper from BP Hobbies. Same authentic brand name.... They are awesome power for sure. Been using them for several years. Very strong pack with reliable power.

I need to find a way to charge this battery because my CellPro10S charger requires a balancing plug and there is not balancing plug on this battery. Do I have to fabricate my own plug?

This is an initial view of the battery pack. Actual weight with wires is 160g. I have a 2000mAh Nimh that weighs 130g. This is a big differential in the available current so if you need that, the additional weight would be OK. Dimensions are 53.3W x 68.5H x 28.5D . Thiere is a small instruction note from Enterland on tue usage. It is generic and does not specifically apply to this pack. Pack label says 30C and 60C pulse. No charge rate info.

Very good pack, can use w/o regulator, direct in RX.

With LiFe charger can be charged, but not with very fast charge, 1C is the best.

Can anyone tell me what's the max discharge rate (C) for this battery? 5c or 10c?

The voltage of these packs is roughly the same as a 5-cell NiMH / NiCd pack (about 7.2V when fully charged), so it CAN be plugged directly to the Rx without a regulator for a really simple and robust setup.



Replacing a NiMH pack is really easy, just unplug it and plug in the A123.

I've been using these packs for about 5 months now in a 31% Extra. Awesome packs! Way better than the NiMH in terms of versatility (no "memory effect" to worry about when topping them off before a day of flying) and LiPo in terms of safety (and no need for a regulator/UBEC).



I really recommend them and will be ordering more soon to replace the other NiXX batteries I still have on Rx's!

excellent battery. Charge very fast and plenty of power. Perfect to be recharged at the field because of the fast charging.
