11.1V 15.6Ah 18650 Battery Pack FAQs

Can the BMS include temperature monitoring or battery level indication?

Yes. We offer multiple monitoring options.

  • 4-level LED power indicators (25/50/75/100%)
  • Custom SOC algorithms for specific applications

How reliable are the cell sources?

We work directly with authorized distributors of leading cell manufacturers including Sunpower, BAK,Lishen and DMECGL, ensuring traceable cell origin. Each batch is supported by original factory certificates and consistency reports.

How is safety ensured?

The standard built-in protection circuit provides over-charge, over-discharge, short-circuit, and over-current protection. We use flame-retardant casing and explosion-proof vent cells, with strict factory safety testing.

What quality controls are implemented?

Five key inspection steps: 100% cell screening, post-welding resistance test, semi-finished product capacity test, finished product aging test, and final safety inspection.
