Notice in Using Battery Please pay attention to followings in case of battery will have leakage, heat etc. Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by. Do not use or leave the battery at high temperature as fire or heater.
Lithium-ion Battery Series PAGE： 8 of 9 Appendix A Suggestions for Battery Packs 1、Selecting principle of nickel strip is often applied to the design of battery packs. Based on the working current of battery packs to make the shunt selection of nickel strip. The common nickel strip could under the current as below: Nickel Strip Type 3*0.1 4*0.1 7*0.15 8*0.
Lithium-ion Battery Series PAGE： 9 of 9 3 、 Voltage protection point value (for single cell ) of protection board or BMS, and selecting principle of protection board. The protection voltage point for monomer should be selected also based on the safety voltage point of Lithium Iron 3.6-3.9 2.0-2.5 cell and protection voltage Phosphate point of IC. Ni-Co- Mn 4.05-4.25 2.5-3.0 Selecting principles of protection board: based on the safety needs of the cell and customers’ requirements.
