How to charge/balance two TrakPower's

So, it would be MUCH better IMO to make a Y adaptor to charge both packs in series using a single 4s+ balancer.

Yeah, I like the idea of a single adapter using one balancer...While I use the packs togther with my own Y adapter on the ESC they are not identical always. Plus I have more than one "set" and sometimes intermix...

The V-Balance claims to support up to 6s - I wonder why they didn't suggest this...

Can you think of a way to make this Y adapter and which balancer would you pick if you had your choice?

Thanks,

Any balancer would work. The Y adaptors I made work with the LBA and the commonsenserc balancers. Since the lipo connections are different for the TPs, it would just be a matter of finding the right connectors that will fit and wiring them up. Pretty simple really. But then you'd have to make SURE you hook them up right or bad stuff could happen since there is no keyed plug like you have with most other lipo packs.
