BSL1830 Plastic Case PCBA Charging Protection Circuit

Summary

• No original, new, no battery cells included.

• Can hold up to 10 pieces of 18650 Li-ion batteries; plastic shell only.

• Component without battery cores, for repairing and assembling battery packs.

• Only for users familiar with battery performance and experienced in battery assembly.

Preparation before assembly:

1. If using new cores:

   • 18650 lithium battery cores must be matched.

   • A group of 5/10 cells must have resistors and capacitors to equalize voltage.

2. If repairing old batteries:

   • Test the voltage at both ends of each cell. If different, charge each cell to the same voltage.

• Ensure all cell voltages are equal before welding the PCB.

Important:

1. No batteries included in the package.

2. Do not order if you need batteries.

3. Do not order if you lack battery assembly knowledge.
