Lithium Ion Battery 12 Volt 12 Ah and Charger

Lithium ion battery in a lead acid case. See picture showing maximum bend angle for J2 terminals to engage battery compartment spring plates (15-30 degrees). Includes dedicated lithium ion charger. Fits all M4 models. Provides 50% more power than the standard 8 ah lead acid at 35% the weight. (Weighs only 1.75 lbs versus 5 lbs for the lead acid. Energy density 82 watt hours per pound versus 19.2 watt hours per pound lead acid. 430% improved energy density.) 

Normal lithium ion voltage operating range: 11.3-12 volts

Built in battery saver circuit protects against full discharge and overcharging. 

Multimeter option provides a seperate digital voltmeter to accurately measure voltage.
