Your battery,in the real world.
mAh capacity + motor draw + actual trigger time. No datasheets, no promises — just the minutes you'll actually play between charges.

ESTIMATED RUNTIME1h 4min
BBS FIRED (APPROX.)7,600Assuming an average ROF of 20 BB/s in bursts
FORMULA: t = (mAh / 1000) / (A · duty) · 60 · 0.85η = 0.85
/ How it works
The numbers behind the math
mAh is fuel
1000 mAh = 1 A for 1 hour. A 1500 mAh pack pushing 15 A continuous lasts 6 minutes of nonstop firing — but no one fires nonstop in a match.
Mind the C-rate
A 25C 1500 mAh LiPo can deliver 37.5 A peak. Below the required C-rate the battery sags — ROF drops and the cell heats up. NiMH and low-C LiPos hate hot motors.
How to extend runtime
Right voltage (not over-spec), MOSFET with active braking, efficient neodymium motor, gear ratio matched to spring. A 30 BB/s monster eats 3× the juice of a balanced setup.
Estimate uses 85% efficiency (sag, losses, idle draw). Measure real consumption with a wattmeter for precise tuning.
