This Enerwatt lithium-ion battery is an actual deep-cycle battery. It is okay to discharge to 100% without damage and to do so repeatedly. An internal battery management system (BMS) helps protect the battery from over and under-charge. It also provides low voltage protection, over-current protection, and automatic balancing of the cells.
Lithium Iron Phosphate batteries are safe and stable for indoor and outdoor use. They do not leak and do not off-gas like other types of batteries. No maintenance is required.

SAFETY
Series Connection
These Enerwatt batteries are designed for 12 or 24 Volt systems only. Never connect more than two batteries in a series connection.
Parallel Connection
Parallel connections can be used. Proper circuit protection is required for each battery to avoid accidentally discharging into a shorted or defective string.
CHARGE SETTINGS
Enerwatt batteries are compatible with standard solar charge controllers.
- Bulk/absorb = 14.2 – 14.6 Volt, with 14.4 Volt ideal
- Absorb time = not needed. 1/2 hr is acceptable or until current drops below four amps.
- Float Voltage - Not needed but can be set to 13.6 Volt or less
- Equalize - Not needed but can be set to 14.4 Volts
- Temperature compensation is not needed but can be set to 0
- A charge rate of up to 8A is possible, though 50A or less is better for longevity.
- The battery has to be warmer than 0 Centigrade (32F), or the BMS will not allow charging, discharge works fine down to -20C (-4F)
- 80 Amp maximum continuous discharge rate. (100 Amp for 10 seconds maximum)
