1. Specifications

2. 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.

3. 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

Perid of Warranty

The period of warranty is 36 months from the date of shipment. MAXLI guarantees to give a replacement in case of battery with defects proven due to manufacturing process instead of the customer abuse and misuse.

Life cycles (BATTERY LIFESPAN)
Up to 100% capacity for 3,000 cycles in recommended conditions. The typical SLA has 400 cycles. MaxLi Lithium batteries last so long that the price per use is a fraction of traditional batteries.

Smart Built-in BMS

passive balancing(active balance optional), low voltage cutoff, high voltage cutoff, short circuit protection and temperature protection for increased performance and longer life. Besies, Bluetooth function for option that enables to monitor battery status, such as, voltage, capacity and so on.

4. Performance and Test Conditions 

Performance And Test Conditions

Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.

5. Standard Charge/Discharge

Standard Charge : 0.2C

Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 14.6V. The battery shall then be charged at constant voltage of 14.6 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.05CA. Charge time: Approx 7.0h, The battery shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.

Standard Discharge : 0.2C

Battery shall be discharged at a constant current of 0.2C to 10V @ 20º ± 5C

If no otherwise specified, the rest time between charging and discharging is 30min.
