Batteries - Sterling AMPS AL1220 LiFePO4 Lithium Battery

The new Sterling Power 12V / 20Ah Lithium Iron Phosphate Battery with BMS and safety shutdown.

Key Features:

Capacity and performance - Lithium batteries allow, when the BMS allows it, full use of the battery capacity, as opposed to the 50% recommended depth of discharge of a lead acid battery. Their low internal resistance allows much faster charge than many other battery types and very impressive rates of discharge.
Significantly lighter and significantly smaller than their lead acid competition.
Even when being discharged to significantly greater degrees than a lead acid battery, we will still expect to see between 10-20 times the service life of a lithium battery against a lead acid batteries
