DR.PREPARE Dr. Prepare 12V 100Ah LiFePO4 Deep Cycle Battery,Rechargeable Lithium Iron Phosphate Battery with Monitor Screen,Built-in 100A BMS,1280Wh Energy for RV,Solar,Trolling Motor DBT12100LFP-S48

[Low / High Temp Cut-Off Protection] In temperatures between 23°F and 41°F or 140? and 158?, the lithium batteries will cease charging. Similarly, in temperatures between -13°F and 5°F or 158? and 176?, the LiFePO4 battery will stop discharging. The low / high temperature cut-off protection ensures the longevity of lithium batteries.

[Built-in Meter] The LCD screen on the top of the battery, displays the remaining battery capacity and voltage in standby mode, charging current and voltage in charging state, and discharging current and voltage in discharge state. It should be noted that the screen display requires calibration before first use or after a long period of non-use. To calibrate, first, discharge the battery to 0%. Second, use a compatible LiFePO4 battery charger or solar charge controller to fully charge it.

[Grade A LiFePO4 Cells & Smart BMS Protection] The advanced Grade A cells inside are UL tested and certified, while batteries have UN38.3, FCC, and RoHS certifications, ensuring a 10-year lifespan and over 5,000 cycles. Built-in premium 100A BMS, there are 6 layers of safety protection for increased performance and longer lifetime, including low temperature, high temperature, over-charge, over-discharge, over-current, and short circuit protection.

[Series and Parallel Connection] Dr. Prepare LiFePO4 batteries are compatible with a 12V/24V/36V/48V 100Ah lithium-ion battery system in series or a 12V 100Ah/200Ah/300Ah/400Ah power system in parallel. The system allows for the connection of up to 16 batteries in series and parallel, providing a powerful home battery bank with a total power output of 20.48 kWh. Note that all batteries must be identical (same brand, type, voltage, capacity, and BMS) and purchased within 6 months.

[About Recharging] 12V (14.6V) 5A/10A/20A/50A Lithium Iron Phosphate-compatible battery charger or solar panel + a solar charge controller to recharge DR.PREPARE 12V 100Ah LiFePO4 Battery. Lead acid battery charger CAN'T recharge DR.PREPARE LiFePO4 Battery.

[Warm Tips] It's an energy storage battery, not a car battery, starting battery or golf cart battery. We suggest using one battery with a 12V 36~55 lbs thrust trolling motor, and 2 batteries are required for a 24V trolling motor.Use a 60A CIRCUIT BREAKER (not included) to protect the battery. Each battery must be fully charged separately by a 12V lithium charger before in series, so that each battery will reach the balance effect in series, not delivering too much voltage to remaining batteries.
