sky-holic lipo balancer?

[miniGranis]

Would be happy if someone can help out a bit since I am new to LiPo.

It this a good balancer for the MaxAmps 2S2P 8000 LiPo's ?
Is it a direct fit on the MaxAmps packs or do I need an adaptor ?

I will be using the MRC 977 and charge two LiPo's at the same time on separate channels, can I alternate the balancer between the packs, ie balance pack A on the first charge (pack B charged without balancer) and the next time balance pack B (and charge pack A without balancer aso.
Or would I need two balancers ?

I will probably switch to the Triton ICE in a while and then charge the two pack in series at 8 amps in the future. The MRC 977 will only do 3 amps on LiPo...
