Grepow was founded in 1998. We are an advanced technology company specialized in the research and production of NIMH, Li-ion batteries, and development of power management systems. After decades of development, Grepow is now one of the largest manufacturers of high C-rate and high capacity batteries in China. So what's the performance of the Grepow VR battery?
VR battery features
1. Lightweight and small size
The total weight and volume are 1/3 of the same size lead-acid battery, which can be easily carried by elderly people, women, and children. Custom shaped batteries to fit into any and all available space in your product for maximum efficiency.
2. Low-temperature resistance
Grepow low temperature shaped battery operating environment in a wide operating temperature range, -40 ° C to 50 ° C. It has broken through the discharge temperature limits of -20℃ to 60℃. High performance of discharge at low-temperature, the lowest one is able to discharge over 60% efficiency @0.2C at -40℃, and discharge over 80% efficiency @0.2C at 30℃.3. Longevity
Lithium-ion batteries charge and discharge more than 1000 times in practical applications, and their capacity is not less than 80% of the original capacity, while the lead-acid battery has only 60% capacity after charging and discharging 200 times.4. Green environmental protection
Lithium-ion batteries have no leakage, no pollution, no heavy metals such as cadmium, mercury, lead, etc., which solve the pollution problem in the whole process of manufacturing and use. It is recognized as a green energy source in the world.
Product advantages
- OEM mass production, mature manufacturing process;
- physical factory supply, quality assurance, and after-sales service;
- battery assembly method requirements can be customized according to customer requirements, custom size! Such as voltage, capacity, packaging color, matching plug model, length of lead wire, etc.;
- can provide integrated power solutions according to customer requirements.
