charging 2s2p lipos in series

[lutach]

I run my packs in series as well. I have adapters that I use to charge them in series or parallel. Just make sure before you start charging that he packs have equal voltage.

I don't mean to hijack threads or anything, but if u have a single charger that balances while it is charging, how do u hook up both balancing leads on the two batteries, or do u have to?

You would have to make a harness to pull all of the balance plugs together for the balance tap on the balancer.
