LiPo battery calculator

Inputs and results

Enter the cell count, LiPo or LiHV chemistry, capacity, parallel pack count, and discharge C value.

The calculator returns pack voltage, energy, charge current, charger power, and current from the C value.

Data and formulas

The existing calculator uses 3.70 volts per LiPo cell and 3.80 volts per LiHV cell for nominal voltage.

Full voltage is 4.20 volts per LiPo cell or 4.35 volts per LiHV cell. Storage voltage is 3.80 volts per cell.

Pack voltage equals cell count times cell voltage. Watt-hours equal nominal pack voltage times capacity in amp-hours.

The parallel capacity equals one pack capacity times the pack count. The 1C current equals that capacity in amp-hours.

The power result uses full voltage, 1C current, and 12 percent headroom. It rounds up to whole watts.

These formulas come from the existing PinionMesh calculator code. Check the battery and charger instructions before use.

Catalog examples

Each product title states the cell count, capacity, and LiPo chemistry.

These calculated values apply to one pack with those inputs.
