This is Forcemech's ForceMax 24V 12.5Ah lithium battery for the Ultralite G20 and the Ultralite G20 PRO, the same battery both chairs ship with. A second one lets you swap in a charged battery and keep going.
Forcemech's 24V 12.5Ah, 300Wh lithium battery for the Ultralite G20 and G20 PRO.
What stands out
People buy a second ForceMax battery for a longer day out or to replace one that has worn down. It is the 24V 12.5Ah, 300Wh lithium battery that ships with the Ultralite G20 and the G20 PRO, and it weighs 3 lbs. Forcemech rates both chairs for up to 12 miles on one battery, so a charged spare in the bag doubles the day. The label shows it was tested to UN38.3 for transport, and Forcemech markets it as FAA compliant. Charge it only with the Forcemech charger that came with the chair.
Straight talk
Is it right for you?
A good fit if you
- own a Forcemech Ultralite G20 or G20 PRO
- want a spare for longer days out
- need to replace a worn battery
Look elsewhere if you
- own an Ultralite G10 or Carbon F1 (they use a 24V 10Ah battery)
