I've built my own DIY battery pack and it's been functioning beautifully over the past few months. 16 cells generally all within 0.01v. However, the battery is in an off-grid remote location nearly 2 hours away and if something goes wrong I'd like to know ASAP. I do have monitoring with VRM and have access to the BMS via a "Peter board", so I can see everything remotely.
I'm wondering if there are any symptoms that would indicate a cell failure (or pending failure)? I can think of a cell's voltage significantly deviating from the rest of the pack, but are there any other metrics provided by a BMS that could indicate cell/battery failure? Does a venting cell release hydrogen? Could you use something like an MQ2 sensor with an Arduino to detect cell venting? Has anyone done that?
