Waterproof Universal Battery Voltmeter and Capacity Display, 12-60V

Most battery capacity indicators are built around one specific cell-count range, which means a workshop running multiple battery sizes - small LiPo packs up through larger multi-cell setups - ends up needing a separate indicator for each. This universal voltmeter covers 12V to 60V in one waterproof unit, a genuinely flexible bench tool for anyone who doesn't want to keep swapping indicators depending on which battery they're checking that day.
