Using Overlander charger and lipo

[soane]

I bought an Overlander Sport 3900 2S 7.4v 25c lipo and RC-6S Balance Charger from Dave at TOP and I'm a little confused on the charging procedure. On the battery it says not to exceed 2C when charging but I thought it should be more like 3 amps? Also, when do I know when it has finished charging?

What it means is do not exceed double the charge rate. The BRCA recommends that Lipos should be charged at 1C or under so for example if you have a 5300mah battery you should charge it at 5.3 amps.

4800mah = 4.8 amps
4000mah = 4.0 amps
3600mah = 3.6 amps
etc,etc.

So check out what your mah is on your cells and charge accordingly.

Ah, I see, so a 3900mah lipo gets charged at 3.9amps or lower? But how do I know when the battery is full?

[rondoolaa]

the charger should automaticly stop charging, just make sure you charge at the correct mah and voltage and set output to lipo

I think I've got it, I don't have a 12v supply in the house so I'll try it tomorrow. The instructions that come with the charger are a little confusing, the ones on the website are a lot better. When it mentions voltage level, I assume it means 7.4v divided by 2s is 3.6v?
