I am having problems charging a new protek 2200maH 14.8V Lipo on my swallow 2 charger. The charger charges all my other lipos but says "output circuit error" when I try and charge this pack. On the multimeter, the pack reads 15.8V, which I would think is about right. I pu i on the balancer, and that seems to recognise it ok. I don't have another charger to try it on.

Anyone have any ideas what is going on ?

Thanks.
