The battery has a nominal voltage of 12.8V and a capacity of 300Ah.
You can charge the battery using a lithium iron phosphate 4-string charger, photovoltaic solar panels through MPPT, or an inverter with a built-in AC to DC charging function
The product comes with a 5-year warranty from the date of manufacture.
Yes, the battery can be connected in series or parallel for larger capacity and higher voltage, with a maximum of 4 batteries in series and up to 10 in parallel.
The battery can operate in temperatures ranging from -20°C to 60°C(-4°F to 122°F), with an ideal storage temperature between 10°C to 50°C(14°F to 122°F)
The built-in BMS protects the battery from overcharge, deep discharge, overload, overheating, and short circuit, and it has a high-temperature disconnect function.
If the BMS cuts off the battery, disconnect the load and let the battery sit for 30 minutes to recover. If it doesn't recover, use a charger with a 0V charging function or connect it in parallel with another 12V battery.
Do not immerse the battery in water, strike it with sharp objects, or connect it to an electrical outlet. Always use a LiFePO4 battery charger.
The recommended charging voltage is between 14.2V to 14.6V.
The battery is suitable for RVs, solar systems, home energy systems, boats, and various portable electronic devices.
