1. Cell allocation and match group (cells voltage cannot lower than 3.0V, voltage difference is not more than 10mV, and Internal resistance 6-8MΩ)
2. BMS test (Over charge/discharge, over current detection, over temperature protection and etc)
3. We will do a functional test when it built into battery pack.
4. Quality department colleague will test battery voltage, current, capacity during production line
5. All battery will do aging test( charge and discharge) before shipping.
And you can see that there are over 200 aging points in our factory. Our machine is Re-power, which is famous aging test machine to promise battery aging data are correct. Besides, our battery pack will have aging test report and Shipment inspection report. (from our QC team)

2. Advantages of MaxLi Low Temperature Lifepo4 Battery Pack
- This battery contains BMS-controlled heating film, and heating film will gently heat the cells when thebattery detects the ambient temperature has dropped below 0°C,
- 2. So, this means you can charge battery as normal at ambient temperatures as low as -20°C.
- 3. Our Bluetooth App also can show heating status now, which very easy to monitor battery informations.
- 4.Auto start heating film with very small current
- 5. Will not use power of cells
- 6. Widely application, camper, motor home, boat, solar system
3. Features of LiFePO4 Battery
- Longer Cycle Life: Offers up to 20times longer cycle life and five times longer float /calendar life than lead acid battery.
- Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop in' replacement
- for lead acid batteries.
- Higher Power: Delivers twice power of lead acid battery ,even high discharge rate, while maintaining
- high energy capacity.
- Superior Safety: Lithium Iron Phosphate chemistry eliminates the risk of explosion or combustion due
- to high impact,overcharging or short circuit situation.
- Increased Flexibility: Modular Design enables deployment of up to up to ten battery in parallel.
