CellMeter-7 Digital Battery Capacity Checker

A pack reading one combined voltage number hides exactly the thing that matters most for battery health: whether every individual cell is still in balance with the others. This checker reads per-cell voltage directly alongside the total pack figure, so a weak or drifting cell shows up immediately instead of staying hidden behind an average that still looks fine.

Support spans NiCd and NiMH packs from 4 to 7 cells and Lithium packs (LiPo, LiFe, Li-Ion) from 2 to 7 cells, covering essentially every chemistry and cell count likely to turn up across a drone, RC car or general hobby battery drawer. The compact black hard-plastic housing at 84 by 50 by 15mm and 63 grams is genuinely pocketable, built for quick checks between flights or charging cycles rather than as a bench-only instrument.

Common uses are checking individual cell balance on a LiPo pack before or after a flight, verifying NiMH or NiCd pack condition on older RC gear, and quick capacity and health checks across a mixed battery collection without needing a full balance charger's diagnostics.
