About JIEYO
A Battery Company Built by Engineers
JIEYO was founded by Mr. Du, one of the first battery engineers at BYD in the late 1990s. After years of R&D in lithium chemistry, he started his own venture in the early 2000s—leading to the establishment of Shenzhen JIEYO Technology in 2011 and Huizhou JIEYO Industrial in 2012.
Mr. Ju, also a former BYD engineer and longtime colleague of Mr. Du, joined as Chief Engineer / CTO. Together, they built a team focused on one thing: engineering batteries that actually fit the application—not just assembling off-the-shelf components.
What We Do
We design and manufacture custom rechargeable batteries across:
-
LiFePO₄
-
Lithium-ion (Li-ion)
-
Nickel-metal hydride (Ni-MH)
-
Sodium-ion (Na-ion)
-
Lithium polymer (Li-Po)
Our Ni-MH cells are produced in-house—giving us full control over quality and supply. For LiFePO₄ and sodium-ion products, we hold our own design patents, ensuring our solutions stand out in performance and appearance.
Where Our Batteries Are Used
-
Power tools – for brands like Dyson, Shark, DeWalt, Makita
-
E-bikes & e-scooters
-
Household appliances – vacuum cleaners, floor scrubbers
-
Lighting & emergency equipment
-
RC models & toys
-
Golf carts, marine, RVs
-
Energy storage systems – residential, commercial, industrial
We use “for” when referencing third-party brands to indicate compatibility, not affiliation.
