I meant that LiPo batteries in general can be damaged that way. I wasn't suggesting that this is something that can happen with the Mint circuitry, because I honestly don't know. If it is properly designed it probably has both over- and under-voltage protection. The LiPo might still over-discharge if you for example leave some load hanging off of the vbat connection for too long etc. On Sep 12, 2014 12:08 PM, "Bill Carter" <[email protected]> wrote:
