Meet the 86 Ah 12V car battery jump starter, These batteries are 26 pounds lighter than standard batteries and 70 percent lighter than lead and can be safely discharged to 100% DOD (depth of discharge), providing twice the energy. They easily replace your OEM battery so you don't have to worry about any wasted space or extra modifications. In addition to being extremely light, these batteries last 2 to 3 times longer than standard lead/acid and other lithium batteries due to the battery management system. It’s time to upgrade your heavy lead-acid batteries to LiFePO4 batteries and upgrade your lifestyle and ability to adventure!

Longer Battery Life

Lead acid battery lifespan is 250-300 cycles while LiFePO4 lifespan is about 4000 cycles. If the battery runs out of its energy without driving the car for weeks, the lead acid battery would probably die after that, but the LiFePO4 battery can be used after recharging, and it doesn't affect its lifespan.

Higher Performance

Our 86 Ah 12V battery jump starter can be discharged at high current, and the current can reach hundreds of amps at startup. After starting, it can be charged with high current, no memory effect, and the charging requirements are not high, as long as the voltage is not higher than 14.5v can be. No need for constant current charging, current size can be charged, low risk, and more stable performance. LiFePO4 internal resistance and higher output current make the spark plug create higher electricity, quickly ignite and engine, and completely combust the fuel.

Reliable BMS System

The advanced BMS utilizing the software controller intelligently monitors the battery's operating conditions and oversees its safe operations. Continuously monitors conditions, redistributes energy resources in no time flat, and sends alerts in the event of a problem.

Auto-balancing Function

Due to the upgraded auto-balancing function, you can combine batteries in parallel more safely. We recommend connecting the batteries with appropriate cables to achieve optimal effect. Please note that do not connect batteries in series, and the maximum number that can connect in parallel is 8.

Bluetooth Monitors Battery

Bluetooth 5.0 is designed to reduce the energy consumption of Bluetooth peripherals. It is faster and operates over longer distances than older versions. You can easily monitor the status of your battery more accurately and conveniently in real time.

Low-Temperature Self-Heating Function

The intelligent self-heating function will start operating automatically once the battery’s core temperature drops below 41°F (5°C), effortlessly keeping your battery charged in cold environments. Plus, this function is powered by the Charger/Controller's current instead of the battery itself.

Lighter Weight

The battery case is made of high-quality ABS material with good sealing performance and solid construction. It weighs about half as much as a lead-acid battery of the same capacity. In usage scenarios, such as RV, Electric Vehicles, it can lead to more free space.

Maintenance Free

Lithium-ion batteries last two to four times longer than lead-acid batteries. Frequently having to maintain your lead-acid batteries can be time-consuming and costly. However, Diypow lithium-ion batteries are virtually maintenance-free and do not require frequent watering, equalization charging, or cleaning.

10 Years Warranty

Diypow LiFePO4 battery has obtained CE, RoHS, PSE, and WEEE certifications. All lithium iron phosphate batteries come with a 10-year conditional warranty covering defects in materials and workmanship starting from the date of purchase. And the battery charger comes with 90 days warranty.


  • DO NOT connect more than 8 batteries in parallel.
  • Please secure all cable connections to proper specification in order to ensure good connections between the cable lugs and the battery terminals.
  • Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.
  • The battery is shipped in shelf mode. Before using the battery for the first time, please activate the battery with a charge/discharge current greater than 1A and measure the terminal voltage to validate.
