[Specially Designed for Trolling Motors & Boats] This kit includes a 12.8V 100Ah LiFePO4 battery with LCD meter and a 60A circuit breaker, perfect for trolling motors, boats, marine electronics, and other high-power devices. It offers dependable protection against overloads and short circuits.The circuit breaker meets SAE J553, J1625, J1428 30A, J1171, and UL 1500 (ignition protected) safety standards, featuring UL 94V-0 flame-retardant housing and IP67-rated waterproofing. [Reusable Manual Reset, Simple Setup] Unlike disposable inline fuses, Dr.Prepare 60 Amp circuit breaker resets with a simple manual switch—saving you money on replacements while preventing electrical hazards. No tools needed! Clearly labeled terminals and surface-mount design let you install between battery and device instantly. (Wires not included.) Reset by placing the bar back in place. [ Coulomb Tech Meter] In 2025, updated with advanced coulomb technology, this meter maintains ≤5% error accuracy. Its digital screen displays the discharging current and voltage in the discharge state, the remaining capacity and voltage in standby mode, and the charging current and voltage in the charging state. Unlike voltage-based meters (which show only battery bars with 30-40% inaccuracy, and only shows battery voltage with level bars.), DR.PREPARE meter provides exact numerical data. [Grade A+ LiFePO4 Cells & Low Temp Cut-Off Protection] The advanced Grade A+ cells inside are UL tested, ensuring a 10-year lifespan. When the temp reaches 23℉~41℉, this lithium batteries will stop being charged, and when the temp reaches -13℉~5℉, this LiFePO4 battery will stop discharging. Low temperature cut-off protection can keep lithium batteries healthy. [Smart BMS Protection & 10-Year Prodcut Support] 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. Dr.Prepare battery provide every customer with 10-YEAR Prodcut Support. If you have any question, please contact us directly. Dr.Prepare customer service team will provide professional knowledge and service to solve your problem! [5,000 Cycles, 10-Year Lifetime] DR. PREPARE LiFePO4 battery has 5,000 cycles at 60% deep discharge and 3,000 cycles at 80% deep discharge, providing about a 10-year lifetime, while only 500 cycles for the sealed lead-acid batteries. The 12V rechargeable LiFePO4 battery provides a maximum of 1,280Wh power output, which is 2 to 3 times more powerful than SLA batteries of the same size. Continuous discharge current can power most electrical devices, such as RV, off grid, fish finders, solar power, electric chair wheel, camping, home alarm system, scooters. [Series and Parallel Connection] Dr.Prepare LiFePO4 batteries are both supported to creat a 12V/24V/36V/48V 100Ah lithium ion battery bank in series or a 12V 100Ah/200Ah/300Ah/400Ah power system in parallel. You can even wire up to 16 batteries in series and parallel to build a powerful home battery bank system with a power of 20.48 kWh. [About Recharging] Use a 12V (14.6V) 5A/10A/20A/50A charger specifically designed for LiFePO4 batteries or a solar panel with controller to recharge DR.PREPARE 12V 100Ah LiFePO4 Battery. Kindly note that Do not use other brand general-purpose chargers to avoid potential damage. Dr.Prepare's compatible charger is available in our store. Lead acid battery charger CAN'T recharge DR.PREPARE LiFePO4 Battery. Each battery must be fully charged separately by a 12V LiFePO4 charger before in series. [Warm Tips] It's an energy storage battery, not a car battery, starting 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. 12V 100Ah Trolling Motor LiFePO4 Battery with LCD Meter & 60A Breaker Kit, Group 31 12.8 volt Lithium Iron Phosphate Battery with 100A BMS, Low-temp Protection for Boats, RV, ATV, Trailers
