WPL31BH WPL31 Battery GR31 LiFePO4 12V (Heat, Bluetooth)
 
This battery has a built-in Bluetooth and Heater! You CAN charge it in cold weather at temperatures as low as -30C (-22F) and discharge as low as -20C (-4F). The Bluetooth feature lets you monitor the battery with a free application from Apple or the Google store.    
 
TheEnerwatt 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 
 
Everwatt 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 100A is possible, though 50A or less is better for longevity.
The battery can be charged in cold weather at temperatures as low as -30C (-22F) and discharged as low as -20C (-4F)
100 Amp maximum continuous discharge rate. (120 Amp for 10 seconds maximum)
