Frequently asked questions
What charger should I use?
Use a charger designed for a 3S lithium-ion pack with a 12.6 V full-charge voltage, and check the pack's protection and charging specifications before connecting it.
Can it power a 12 V device directly?
The pack's voltage changes with charge level, from about 9 V when discharged to 12.6 V when full. Use a regulator or inverter that accepts this range for 12 V loads.
