SpecificationsRated Capacity (0.2C): 280Ah /3584WhRated Voltage: 12.8VCharge voltage: 14.2 - 14.4VDepth of Discharge (DoD): 100%Standard charge current: 40ACharging time: Approximately 8 hoursMax charge current: 200AMax continuous discharge current: 200APeak discharge current: 600A (Duration: less than 3 seconds)Operating temperatures: Charge -20°C~50°C(-4℉~122℉), Discharge -20°C~60°C(-4°F~140°F), Storage -20°C~50°C(-4°F~122°F)Impedance: ≤ 5mΩCHINSSize: 20.47 x 9.44 x 8.58inchs1. About the low temperature protection functionWhen the temperature is lower than 0°C (32°F), the battery pack will trigger the low temperature protection.2. About chargingWhen the temperature is lower than 0°C (32°F), when charge the battery, regardless of the charging current, it will first charge the battery's heating film and activate the battery's internal heating function.3. Heating time of heating filmWhen the temperature is lower than 0°C (32°F), please directly connect the charger or MPPT to heat the battery pack. It is heated from 0°C (32°F) to 10°C (50°F) for 1.5-2 hours. 【Bluetooth Function】: Compared with the traditional battery monitor, CHINS Bluetooth 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 Smart 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 10A. 【Lithium Iron Technology】: CHINS Bluetooth lithium iron battery have exceptional longevity since they manufacturing by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & 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 【Capacity Expansion】: CHINS LiFePO4 battery 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 1200Ah) and higher voltage (24V, 36V, 48V). Other installation methods: 4S2P, 2S2P, 3S2P, etc. 【Built-In BMS & Convenience & Maintenance Free】: CHINS Bluetooth 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.
