Anyone thought about using one of these for charging the 2 batterypacks?
It can do 2 or 3 cell LIPO with sensor
Good guide to charging LIPO by RC people and we use these batterries a lot!
OR the totally different way to move - make it part of the OpenROV!

2pcs should be eanough as one can charge from 2 to 4 batteries at 2A
Doesn't require lot of additional components accept few resistors, diodes(can be left out) and capacitor(s).
