That is a good point. What's a good LiPo protection circuit look like? Some googling led me to some basics that a protection circuit should have, does this look about right?

- Overcharge protection (prevent charging past the max voltage, probably ~4.2V but intentionally shrinking this window might prolong cell life)

- Short circuit protection (Like, a fuse? Would a PTC one work?)

- Limit charge current (0.5-1C for LiPos, 5-10C for LiCaps, etc)

- Undercharge protection; prevent discharge past a 'low voltage' value and (ideally) permanently disable cell or severely limit charge rate if voltage drops below the minimum safe value.

- (Ideally) Balance voltage between individual cells.

Oh, sweet - thanks!
