Hello all.

What do you guys recommend as far as charging two 2s batteries at the same time? My charger can handle up to 4s.

I understand the whole concept of charging the two batteries in parallel. My questions though is how do I do balancing if there is only one battery port on the balance board? Can someone recommend or link me to a balance board I can use where it can balance both 2s batteries being charger in parallel?

Or do you guys recommend I charge in series so that the charger sees the two 2s as a one 4s battery?

I use a Duratrax Onyx 235 charger.

What do you guys recommend and do they make board that can have two 2s battery balance plugs connected to it at the same time? Thanks!
