Introducing the Keheng LITHIUM 12V 100AH DEEP CYCLE LIFEPO4 BATTERY.

Allow us to present the epitome of lithium deep cycle battery technology, the 125 Ah 12 V LiFePO4 Deep Cycle battery! Weighing a mere 31 pounds, this battery surpasses expectations by delivering power and alleviating any battery-related worries. Designed for a wide range of applications, including marine, RV, van, and off-grid systems, this 12v lithium-ion battery pack beckons you to upgrade your lifestyle to one of adventure and freedom.

Furthermore, this exceptional battery offers the convenience of Bluetooth functionality. Seamlessly connect and control your battery with ease.

Safeguarding your battery and ensuring optimal performance is a meticulous Battery Management System (BMS) equipped with low-temperature cut-off protection. When charging the battery under freezing conditions (below 0°C), the BMS acts swiftly, automatically cutting off the charging process for enhanced safety.

The 125 Ah 12 V LiFePO4 Deep Cycle battery boasts an impressive life expectancy of 3000-5000 cycles*, delivering a continuous current of 125 Amps and a surge current of 200 Amps for 30 seconds, with a ½ second surge available for heavier loads.

Keheng lithium batteries outshine traditional lead-acid batteries by offering increased energy storage for high-consumption demands. Experience the swiftness of ultra-fast charging and discharging, the efficiency of high energy conversion, and revel in the extended cycle life—all without the burden of maintenance.

Please note that after approximately 3000 cycles or more, the battery capacity may retain around 75-80% under applications recharging at 0.5C or lower. Our rigorous lab testing has even shown life spans exceeding 5000 cycles.*

*Please note that the ‘approximately 75-80% battery capacity retention after 3000 cycles’ and ‘life spans exceeding 5000 cycles’ are based on our lab testing and may vary depending on usage conditions and charging rates.

Maintenance free, fully sealed and waterproof.


What features are available?
Optional LCD display and Bluetooth for real-time battery status monitoring.

Can I use it in cold temperatures?
No. If the battery is used in temperatures above -20°C, it will affect the battery's performance.

How long will my lithium deep cycle battery last?
There are several factors that can affect battery life. Weather, temperature, charge cycles, depth of discharge (DOD), discharge current, charge current, charging method, vibration, and static use time can all have a huge impact on battery life. A properly maintained lithium deep cycle battery will last approximately three times as long as a lead-acid battery used under similar conditions. Life expectancy is typically 10 years or more, and our batteries (30Ah and above) carry an 11-year warranty.

How can I maximize the life of my lithium deep cycle batteries?
The battery life of lithium batteries can be extended by not discharging the battery to 1Ah capacity or to the lower voltage cut-off setting of the BMS. Discharging to the lower BMS voltage cutoff setting will quickly shorten the life of the battery. Instead, we recommend discharging the battery to 20% of its remaining capacity and then recharging.
