Batterie à cycle profond LiFePO4 12V 12Ah

Yes, of course! If you purchase our battery with low-temperature cutoff, our BMS has low-temperature protection cut-off function to protect your battery from low-temperature damage and extend battery life.

Low temp cut off protection (Charge): 0℃ ± 4℃ (32°F ± 39.2°F)

Low temp cut off protection (Discharge): -20℃ ± 4℃ (-4°F ± 39.2°F)

We recommend using a lithium iron phosphate 4-string (14.6V) charger to charge the battery.

Additionally, you have two other options:

Scheme 2: You can use photovoltaic solar panels to charge the battery through MPPT.

Scheme 3: You can use an inverter with a built-in AC to DC charging function to charge the battery pack.

a. A Battery Management System (BMS) is responsible for protecting the li-ion cells and the user from unsafe operating conditions, such as low or high voltage, low or high temperatures, and system shorts. It shuts off the battery to prevent damage.

b. Our BMS also ensures cell balance. During each charge cycle, it reduces the charging rate in cells that have been topped off first, allowing other cells to catch up. This maintains cell balance and ensures the quality and efficiency of the battery pack.

Our LiFePO4 lithium iron batteries provide 2000+ cycles, compared to 300-500 cycles in lead-acid batteries. The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.

Our LiFePO4 batteries are manufactured using automotive-grade LiFePO4 cells, offering higher energy density, no memory effect, more stable performance, and greater power.

The stable Lithium Iron Phosphate chemical structure makes LiFePO4 batteries resistant to burning or exploding, even at high temperatures, short circuits, impact, and drops. They have been tested and certified for safety by UL.

Our batteries do not contain heavy metals or rare metals, making them more environmentally friendly. They are often referred to as green batteries.

All our lithium battery products have a built-in battery management system (BMS) that protects against overcharge, deep discharge, overload, overheating, and short circuit. The BMS also ensures a low self-discharge rate.

Furthermore, our BMS has a high-temperature disconnect function. When the internal battery temperature reaches 75°C (167°F), it automatically disconnects to protect the battery. It also disconnects if the overcharge voltage exceeds 15V or the overdischarge voltage drops below 8.8V.

We apologize, but our batteries cannot be used to jump-start a vehicle. However, they can be used as a power supply for automobiles. You can recharge your car using a Jackery power supply cord, which is available for purchase separately.
