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.
