About 5 hours of full heat on one charge. The same battery that ships in every kit.
One charge, one night block
This is the battery the kit runs on. Charge it in about 6 hours, seat it in the unit, and it holds the target at temperature for about 5 hours at full heat. Turn the power down and it runs longer. Programs keep a second one charged so the line never waits.
Why a second battery earns its keep
At full heat one battery covers about 5 hours. At 50 watts it covers about 10. Most single-lane shooters never need more. Programs running back-to-back blocks keep a spare on the charger and swap at the break, so the target never cools and the line never stands around. The swap takes seconds and no tools.
