Why choose a LiFePO₄ battery?

LiTime uses high-quality EV Grade A lithium iron phosphate (LiFePO₄) cells, considered one of the safest and most reliable lithium battery technologies. Compared to lead-acid batteries, LiFePO₄ batteries are significantly lighter, allow nearly full use of their capacity, and offer a much longer lifespan. Thanks to their high thermal stability, they are also ideal for marine applications.

• Long service life
• High thermal stability
• Up to 100% usable battery capacity
• Significantly lighter than lead-acid batteries
• Fast charging
• Maintenance-free operation

Smart BMS protection system

The integrated 50 A Smart BMS protects the battery from overcharging, overdischarging, short circuits, overload, and overheating. Additionally, the system includes low-temperature protection and advanced safeguards against moisture, dust, and salty environments, making the battery ideal for use in boats and coastal areas. The battery automatically recovers from overloads without manual intervention.

• Overcharge protection
• Overdischarge protection
• Overcurrent protection
• Short circuit protection
• Overload protection with automatic recovery
• Overheat protection
• Low-temperature charging protection (0 °C)
• Low-temperature discharging protection (-20 °C)
• Automatic cell balancing

Bluetooth monitoring

The built-in Bluetooth 5.0 allows monitoring of the battery’s state of charge (SOC), voltage, current, charging and discharging data, and overall battery status in real time via the LiTime mobile app. The app also enables turning the battery on and off directly from your smartphone.
