Final Battleborn Video: Overheating Cells

The video investigates a significant capacity issue with Battleborn batteries. After testing 12 batteries, each rated for 100 amp-hours, the results showed a drastic reduction, ranging from 26 to 60 amp-hours. This inconsistency prompted a deeper investigation, involving disassembling the batteries to test individual cell packs. These internal tests revealed that all four cell packs within each battery were heavily degraded. Further testing on a second battery yielded similar results, with individual cell packs showing capacities between 13 and 47 amp-hours. Thermal imaging during charging highlighted that some cells were drawing all the current while others remained cold, indicating a current-sharing problem.
