Melasta Lithium Iron phosphate (LiFePO4) cells are one of the best qualities cells available in the market with these technological features
1. High Capacity of single cells upto 6500 mAh.
2. Multiple Shapes with 14500, 18650, 26650, and 32600.
3. Wide Discharge rate range from 1C to 15C.
4. Wide range of operating temperature from -20℃ to 60℃.
5. Ultra Long Cycle Life 2500 Cycles @ 80% remaining Capacity.
Cylindrical cells one of the most widely used lithium ion battery shapes due to ease to use and good mechanical stability. The tubular cylindrical shape can withstand high internal pressures without collapsing. Melasta produces multiple sizes and capacities according to the customer requirement. These cells are mostly used in Electrical vehicles such as golf cart and in power tools.
Melasta is one of the main producer and supplier for LiFePO4 batteries in China. Our batteries have the features due to our superior technologies and state of the art manufacturing facilities and investment on research and development.
Melasta LiFePO4 battery has very long lifespan due to its superior performance, and proven quality. it provides more than 2500 life cycles with 80% Depth of Discharge (DOD)at 25℃ temperature.
These batteries are very light weight as compared to the Lead-acid batteries and all other old technologies. Due to this property these batteries are popular batteries in e-mobility industry to outperform the old technologies such as lead-acid batteries.
Melasta uses high quality material for battery production. These LiFePO4 cells do not contain any hazardous material so these are fully environment friendly and recyclable.
Operational temperature range is very wide it operates on extreme temperatures. The normal operational temperature range is from -10℃ to +60℃. These cells are also used as starter batteries in extremely cold temperatures.
These batteries have very low internal resistance which is very favorable for its safety. It delivers high current on demand and keep the battery temperature at normal level.
Normally old technology batteries such as lead-acid batteries required regular maintenance which increases the over cost of the battery system. Melasta Lithium Iron Phosphate Battery out performs the lead acid battery and provides the maintenance free solution.
Low Temperature Lithium Iron Phosphate (LiFePO4) Cell Technology1. Stable discharging current at Low- temperature
2.Suitable cells for military equipment, aerospace industry, and IoT Devices in freezing weather
3. Can be used 70% of initial capacity at -20℃
5. Highest Safety Standards
