quark125 li-po setting?

[BrianG]

Charge them like you would normally with lipos: Hook them up to the balancer and charger and set the charger for a 1C rate (5A in your case). I assume you'll be running the 2s packs in series? If so, charge them that way too and set the charger for 4s. Lipos typically come with at around half charge, so the first time will take less time and will take less mAh.
