Parallel Charge High "C" Different Capacities
 

Hi,

I'm looking at getting into parallel charging but with different mAh capacities. I understand that if the capacities are different you add them all up to get the required Amps - EXAMPLE: 5000mAh + 3850mAh = 8.8Amps but this is based on a 1C charge rate. What happens if the packs can be charged at different C ratings (5000mAh=25Amps@5C, 3850mAh=30.8Amp@8C). Can I just set my charger to it's maximum charge rate 20Amps and both batteries will reach full capacity or do I HAVE to charge at 1C?

Any input will be greatly appreciated!

You should charge at the lowest charge rate of the two batteries.

Thanks for the reply. So if they both can handle 20Amps I can charge at 20Amps??
