Custom Lithium Ion Battery Solutions
As a lithium ion battery manufacturer, we specialize in custom lithium ion batteries solution for drones, lithium battery packs, lithium polymer batteries, and energy storage systems, providing reliable OEM and ODM customization.
Trusted Lithium Ion Battery Supply for Power, Safety and Longevity
Our lithium ion battery supply combines advanced stacking technology, strict safety inspection, and extended cycle life design to deliver batteries that perform reliably even under demanding operating conditions.
High Energy Density
Using stacking process, our soft-pack cells reach up to 250 Wh/kg and, delivering up to 25% longer runtime under the same size.
Reinforced Safety
With 100% OCV, IR inspection and constant climate-controlled workshops, our batteries are built to stay safe even under heavy load ( 3.8-3.9V ) . High Current, Still Steady.
Extended Cycle Life
With 800-1500+ cycle life and long-term retention testing, performance degradation stays slow and predictable throughout the battery's lifetime.
Custom Lithium-Ion Battery Packs for Diverse Applications
Designed for high performance, safety, and long life, LiPo solutions ensure your devices and equipment operate efficiently in demanding environments.

Successful Cases

So luckily, after switching to his high capacity drone battery, we saw more consistent flight times and fewer unexpected voltage drops across our fleet, which directly improved our inspection efficiency.
Trust me, their FPV packs hit hard but remain controllable. The C-rate feels real, and the performance from pack to pack is stable enough for both training and race days.
For our RC aircraft series, we needed lightweight packs with reliable cycle life. NewYenK helped us balance weight and capacity, and the return rate on batteries has dropped significantly since launch. Smart Choice!
