Our CHINS 300AH Smart 12.8V LiFePO4 Lithium Battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. The CHINS 300AH Smart 12.8V LiFePO4 Lithium Battery built-in high temperature cut off prevents charging over 122 °F (50 °C).
The CHINS 300AH Smart 12.8V LiFePO4 Lithium Battery is an Official Nomadic Supply Company Product that we use on our own Mercedes Sprinter vans! CHINS batteries are the best battery for the price on the market, with the highest customer ratings of any lithium battery.
CHINS 300AH Smart 12.8V LiFePO4 Battery w/ Built-in 100A BMS Features:
- Bluetooth Function: Compared with the traditional battery monitor, CHINS smart lithium battery has added Bluetooth function and obtain various data (SOC) of the lithium iron phosphate battery. Customers can connect to the battery through the mobile Phone APP, and read the battery voltage, current, battery capacity and other important information at any time. Wireless connection range: within 5-10 meters from the battery.
- Heating Function: Only when the battery starts to charge, the heating function inside the battery can be turned on. When the ambient temperature is lower than 32°F (0°C), the charging current will only supply power to the heating film inside the battery. When the internal temperature of the battery reaches 50°F (10°C), BMS will immediately turn off the heating function, all the charging current charges the battery. The charging current of the low temperature heating battery is at least 5A.
- Lithium Iron Technology: CHINS deep cycle lithium ion batteries have exceptional longevity since they manufacturing by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance and greater power, letting you use the battery more freely. Our batteries are more cost effective, so when factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. It can support fast charging and solar panel charging.
- Built-In BMS and Convenience and Maintenance Free: Our LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high temp cut off prevents charging over 122 °F (50 °C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults. Highest-level safety based on UL Testing Certificate for the cell inside the battery pack.
- Capacity Expansion: Our Lifepo4 batteries can be connected in parallels and in series for larger capacity and voltage. Max connection in series: Up to 4 identical batteries for up to 48V connecting in series. Connection in parallels: it can connect multiple batteries, suggest no more than 4pcs in parallel. Allow to be extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 400Ah) and higher voltage (24V, 36V, 48V). Other installation methods: 4S2P, 2S2P, 3S2P, etc.
