EUC battery pack calculator
Calculate electric unicycle battery voltage, capacity, energy, current limits and theoretical range from cell chemistry and series/parallel configuration.
Degradation simulator
How capacity and range change over charge cycles.
Degradation curve assumes standard NMC aging at 25 deg C with 80-100% charge window. Real degradation varies with temperature, charge habits, and cell quality.
Future chemistry comparison
Same S/P configuration with next-gen cell technology. Estimates based on published lab data and manufacturer roadmaps.
| Chemistry | Energy (Wh) | Weight (kg) | Density (Wh/kg) | vs current |
|---|---|---|---|---|
| Current baseline | - | - | - | - |
| Silicon anode NMC (est. 2026-2027) | - | - | - | - |
| Solid-state (est. 2027-2029) | - | - | - | - |
| LiFePO4 equivalent | - | - | - | - |
| Sodium-ion (est. 2026-2028) | - | - | - | - |
Solid-state and silicon-anode projections assume ~1.4-1.8x gravimetric density improvements. Sodium-ion trades density for cost and safety. LFP uses 3.2V nominal. All numbers are estimates - real products may differ.
This tool calculates theoretical pack specs from cell datasheets. Real-world performance depends on BMS, wiring losses, cell matching, and thermal management. Always verify with manufacturer data.
How the battery pack calculation works
Series count determines pack voltage; parallel count determines capacity and shares current across cells.
Pack energy is calculated from nominal voltage and amp-hours. Current and voltage-sag outputs remain theoretical cell-level estimates.
Real performance also depends on BMS limits, wiring, cell matching, temperature and controller behavior.
EUC battery calculator FAQ
What do S and P mean in an EUC battery?
S is the number of cell groups in series and sets voltage. P is the number of cells in parallel and increases capacity and available current.
How are EUC battery watt-hours calculated?
Multiply nominal pack voltage by capacity in amp-hours. The result is theoretical Wh; usable energy is lower because of reserve, losses and battery condition.
Does a higher-voltage EUC always have more range?
No. Voltage affects the power platform, while range depends mainly on total Wh and real Wh/km consumption.
