Full Description
Built-in intelligent BMS, optimizes the performance and safety of the battery by automatically balancing cells and protecting them from over charge, over discharge, over current, short circuit, high and low temperature protection functions, graded alarm and wireless monitoring functions.
Using the lithium-ion battery, green and eco-friendly, low lifetime cost.
Automative-level internal design: Not like the traditional assembling method, we apply an aluminum case rather than a normal pvc and adhesive tape inside for a more compact design. It's strict but smart for the long period and surpasses expectations by being versatile, compact, and more powerful.
Brand promotion: OEM/ODM acceptance As a factory with a strong technical team, we focus more on design and offer OEM and ODM services for our clients than promote our own brand.
