For 18650 3.7V 15.6Ah Li-ion battery pack
High energy density
Potential for yet higher capacities.
Relatively low self-discharge
Self-discharge is less than half that of nickel-based batteries.
Low Maintenance
No periodic discharge is needed; There is no memory.
· Very low profile
Batteries resembling the profile of a credit card are feasible.
· Flexible form factor
Manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
· Lightweight
Gelled electrolytes enable simplified packaging by eliminating the metal shell.
· Improved safety
More resistant to overcharge; Less chance for electrolyte leakage.

1. Use at temperature below 40° C, charge fully prior to long storage periods or if it has been stored for more than three months
2. If you find any single battery voltage is under 2V at room temperature, the battery has been over-discharged or is self-discharging due to some defect/parasitic load. Discontinue use until the fault can be corrected and the battery be recharged
3. Store in an open, well ventilated, dry, clean area, between -20° C to 40° C for maximum life. Self-discharge will accelerated at higher temperature
4. Don't expose the battery to extremes of temperature over 60° C, directly to sources of heat, direct sunlight or moisture and/or rain

1, OEM orders are welcome
2, Tags, plugs and connectors are available.
3, Superior quality and cost-performance ratio
4, We could design and develop Li-ion battery per customer's product working
