• 15 dead Battle Born LFP batteries examined, expanding dataset beyond Will Prowse’s initial samples. • Symptoms varied: charging refusal, overheating terminals, no life, charged cells with non‑responsive BMS. • Internal autopsy revealed molten plastic, loose wiring, and corrosion from moisture or electrolyte leakage. • Load and charger tests are essential to determine functionality beyond measurable charge. • Lower charging currents worsened melting issues, indicating load‑rate sensitivity in battery failure. • One 300A‑rated industrial unit failed violently, venting a cell and loose BMS.
Article Summaries:
- Because size matters when it comes to statistics, [Will Prowse] decided to not just bank on his handful of failed Battle Born LFP batteries when it came to documenting their failure modes. Instead he got a whole gaggle of them from a viewer who had experienced failures with their Battle Born LFP batteries for an autopsy, adding a total of 15 samples to the data set. Interestingly, the symptoms of these dead batteries are all over the place, from a refusal to charge, some have the overheating terminal, some do not show any sign of life, others have charged cells but a non-responsive BMS, etc. A
