## Description

12V 300Ah LiFePO4 Battery, Built-in 200A BMS, 18000 Deep Cycles, 3840Wh, Low Temp Protection Lithium Iron Phosphate Battery for Home Energy, RV, Trolling Motor, Marine, Solar, Off-Grid

## Features

- Integrated 200A BMS Protection:Integrated Battery Management System (200A BMS) protects the lithium battery from overcharging, deep discharge, overload, overheating, short circuit, and low self-discharge. Lifepo4 battery current can reach up to 230A. If the internal temperature drops below -20°C or exceeds 65°C, the system will automatically disconnect the battery (with a deviation of 1–2%)
- Safe and Reliable: 12v lithium ion battery 300ah weighs only 25.54 kg. just one third of the weight of a traditional lead-acid battery making it easy to transport and install. Lifepo4 battery has no memory effect, does not store usage data, and is environmentally friendly. Even under strong vibrations, there is no risk of explosion
- High Quality Lithium Battery Cells: LiFePO4 (lithium iron phosphate) battery, made from A-grade cells, supports up to 18,000 charge cycles and still retains 80% of its capacity after 5,000 deep cycles. With an energy capacity of 3840 Wh, this deep cycle battery can deliver up to 120,000 kWh of power over its 15-year lifespan. Compared to lead-acid and AGM batteries, lithium batteries offer higher efficiency and up to five times the lifespan. Additionally, the total cost of a LiFePO4 battery over 15 years is only 60% of that of a lead-acid battery
- Easily Expandable Battery System: Lithium leisure battery can be expanded in a 4P4S configuration – up to 4 in series and 4 in parallel to achieve higher capacity and voltage. 12v lithium battery maximum capacity can be extended to 4800Ah (61.44KWh) or 51.2V. In addition, the battery supports three charging methods: a LiFePO4 charger (recommended: 14.6V 10A / 14.6V 20A), solar panels with a charge controller, and an AC generator
- Wide Range of Applications: 12V 300Ah lithium battery, with a storage capacity of 3840 Wh, complies with the Group 31 standard and is suitable for powering RVs, trolling motors, solar panels, boats, campers, and off-grid systems. It withstands extreme conditions and reliably delivers stable energy for both indoor and outdoor use
