Curator's pick: TK15 High Precision 50A Battery Tester
Without a dedicated shunt-based tester like this, you are just guessing at your remaining runtime; voltage alone is a terrible metric for LiFePO4 because the discharge curve is too flat to read accurately.
⚠ Worth knowing: These batteries lack internal heating elements, meaning you cannot safely charge them if the ambient temperature drops below freezing without risking permanent cell damage. If your setup isn't in a climate-controlled area, you'll need to add an external heating pad first.
