Topband can design and manufactur Lithium ion battery module for industry and specialized application, and also provide customized LiFePO4 battery solution for various filed, such as enegy storage, PV system, solar street light, electric vehicle, etc. Welcome contact us for any inquiry.

1. Advantage:

• Longer life: more than 2000cycle times, 5-7years of cyclelife, while Sealed Lead Acid batteries only 750 cycles and NiMh batteries only 500 cycles
• Steady peformance: Higher capacity and voltagewe can install many single cells in series and in parallet and it can fully discharge,while SLA batteries only 70% to fully discharge
• More powerful, cost effective: high discharge current,1C continuous,3C pulse for normal cells and 20 C for special design
• Safer: never explode and stable in high temperature
• Lighter and smaller: 1/3 weight and 1/2 size of SLA batteries. 70% size/weight of NiMh/NiCd batteries
• No memory effect: it can be recharged anytime,no reduction of the capacity
• Wide operating temperature: -20-60 degrees Celsius
• Green product: totally environment friendly
• Can be charge by solar power charger.

3. Safety Characteristics

• Over-charge/Over-discharge Ability to withstand over-charge/withstand over-discharge, and there is no fire, no exploding and work well
• Short circuit Ability to withstand short circuit, and there is no fire, no exploding
• Acupuncture Ability to withstand nail puncturing, and there is no fire, no exploding
• Thermal shock Ability to withstand thermal shock, and there is no fire, no exploding

4. Storage & Transportation

* Based on the character of cell, proper environment for transportation of LiFePO4 battery pack need to be created to protect the battery.

* Battery should be stayed in the warehouse 15℃～35℃ where it’s dry, clean, shade, and well-ventilated.

* The battery should be stored in 50% SOC during transportation.

* The battery need to be charged every 6 months if out of use

* Keep the battery against dropping, turning over and serious stacking during loading.

5. Battery operation instruction

1. 1 Charging current:Do not surpass the largest charging current that specification stipulated.

1. 2 Charging voltage:Do not surpass the highest limited voltage that specification stipulated.

1. 3 Charging temperature:within temperature scope that specification stipulated.

1. 4 Charge with constant current, then with the constant voltage, no reverse charge, which is dangerous

1. 5 Special note:

Short time doesn't affect the use of the battery overcharge too, but for a long period of time over discharge or over charge can affect the function of the battery failure, or the battery can't use permanent, appear serious safety hazards, need long time floating please use the recommended floating model specification.Battery when not in use for a long time, because of its own self-discharge characteristics can also cause discharge, to prevent the occurrence of a discharge, battery should maintain a certain capacity, maintain the voltage at 50% state of SOC.
