12V 125ah lithium (lifepo4) battery deep cycle


Keheng’s 12V 125ah lithium (Lifepo4) battery deep cycle has a significant advantage in terms of power and size, being only 1/4 the size of a lead-acid battery while holding 5-10 times the power of a lead-acid battery. This battery is designed for all types of applications, whether you need to use it in a boat, caravan, caravan, van, or torpedo boat, he can bring you an unparalleled experience, choose keheng lithium battery to upgrade your adventure.

We offer all kinds of customization for our customers, you can choose the Bluetooth function customization to be able to know the status of the battery at any time through the app.

Customized BMS module, a good BMS can better protect your battery to ensure optimal performance, while the battery management system (BMS) protects the battery such as overcharging to ensure the battery does not catch fire and explode.

Customized heating module, if you need to use the lithium battery at 0℃, then the battery with a heating module can ensure that the lithium battery exists vitality at all times, and will not affect the battery performance because of the outside temperature.

12V 125ah Lithium (Lifepo4) Battery Deep Cycle Features:

The cycle life reaches more than 5000 times. (Battery capacity retention after 3000 cycles is about 80-85%” and “Life expectancy over 5000 cycles” are based on our lab tests and may vary depending on usage conditions and charging rate.)

Charges up to 4 times faster than lead-acid batteries! (Reduced downtime and increased productivity)

Reduced weight makes it easier to carry and disassemble.


12V 125AH deep cycle lifepo4 lithium power battery for RV/Marine/Golf Cart/Scooter/Solar Battery/AGM and amr
Operating temperature up to -20°C
Optional LCD display for real-time battery voltage and capacity.
100A continuous output current for continuous charging of high power devices.
Intelligent BMS system for precise control of the battery to improve battery life without explosion or fire.
Replacement for heavy-duty lead-acid batteries (AGM / GEL) at one-third the weight with the same capacity.
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.
