Sterling AMPS AL1220 LiFePO4 Lithium Battery - 12V / 20AhThe 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
