Simple Guidelines for Using Lithium-ion Batteries
1. A failing Li-ion begins to hiss, bulge and leak electrolyte.
2. The electrolyte consists of lithium salt in an organic solvent (lithium hexafluorophosphate) and is highly flammable. Burning electrolyte can ignite combustible material in close proximity.
3. Dowse Li-ion fire with water or use a regular fire extinguisher. Only use a Class D fire extinguisher for lithium-metal fires because of the reaction of water with lithium. (Li-ion contains little lithium metal reacting with water.)
4. If a Class D extinguisher is not available, douse a lithium-metal fire with water to prevent the fire from spreading.
5. For best results dowsing a Li-ion fire, use a foam extinguisher, CO2, ABC dry chemical, powdered graphite, copper powder or soda (sodium carbonate) as you would extinguish other combustible fires. Reserve the Class D extinguishers for lithium-metal fires only.
6. If the fire of a burning lithium-ion battery cannot be extinguished, allow the pack to burn in a controlled and safe way.
7. Be aware of cell propagation as each cell might be consumed on its own time table when hot. Place a seemingly burned-out pack outside for a time.

Support OEM, logo print for yours is ok.
Custom voltage, working current, Bluetooth BMS and CAN all is ok.
If you need it, pls let us know freely, engineers will design it according to your requirements.
