BATTERY SIZING CALCULATOR
132 FT DRAG · weight, gearing, kV, cells and pack IR → peak amps, sag, motor load
Starting numbers are EXAMPLE ASSUMPTIONS, not measured EVUL data. Check against a logged pass (X.BUS Data Lab or XC-Link). Size by measured IR and sag, not the label C.

Tiers: green good · yellow caution · RED race zone, at the limit (normal for drag racing) · striped BEYOND LIMIT = past the motor's published ratingFuel gauge: share of the pack one pass usesSag bar: white = volts per cell at peak · red zone = below your floor · amber = caution marginEffective C = deliverable amps ÷ Ah
