Problems with Tenergy TB6B Charger

Anybody have problems charging a Parallax branded 3300 mAh battery?

5300 seem to charge fine in balance mode.

I get "Battery Vol Error Cell Connect" on two batteries. Cell balance error?

I charged both up without the balance, and my battery alarm module seems satisfied.

    What are the voltages of the individual cells?

    I occasionally have to charge a single cell individually if the pack gets too far out of balance.

    To charge the individual cell I use a constant current power supply.

    I don't have any of Parallax's 3300 mAh packs myself.

    I have
    4.13
    4.16
    4.13

    All seem in spec. I have another just doing standard Li-Po charging with no balance. I'll check those cells later.
