battery charging

Hi, from the name i'd guess your charger is an IMax B6 type clone - you may want to check what the charge time cut-off is, as I think its usually set by default - and 75 mins is a round-ish number so you may have hit the charge time cut-off before the pack was fully charged. Oh and like everyone else said, don't charge above 1C. Even with my newer batteries that can take more, I don't trust my cheap charger :)

I'd totally suggest something like this, very useful if you have more than a couple of batteries..

i'm told you can do the same with a multi-meter and some maths, but I was never any good at maths :)

A 2200mAh LiPo can be charged with 2,2A (2200mAh).

But if you want your LiPo to last long you should only use half of that: 0,5C = 1,1A or 1100mAh. This will double the charging time needed.

That is a long time to charge a 2200mAh lipo. I use a Hyperon 615 Duo which is capable of charging at a higher rate, on 3S I typically charge at 4.4A. I would experiment with seeing how high you get the charger to go. I don't even charge my 1S lipos at less than .7A and that takes a long time and they are only 500mAh.

Sorry the charger started to beep 2 seconds after i saved my post blinking "Full" :) It had been charging for 75 minutes so i guess it was a ok setting at 0.1a.
