Keeppower has recently launched a series of higher-capacity version Li-ion 26650 rechargeable batteries, the unprotected 26650 7000mAh (Part Name: UH2670) and protected 26650 7000mAh (Part Name: P2670C). These batteries represent a significant leap forward in capacity.
Compared to Model: UH2660 and P2660C in the same series, the UH2670 and P2670C boast an approximately 17% increase in capacity.
This enhancement means the new products can deliver extended power longevity, reducing the frequency of charges—a particularly advantageous feature for high-drain devices that consume energy rapidly. Despite this boost in power, the dimensions of these batteries remain virtually unchanged. This advancement allows consumers to enjoy prolonged usage times, higher energy density, and greater capacity, all within the compact form factor of a cylindrical lithium battery.
We have always adhered to the philosophy of “Keep innovation, empowering possibilities,” dedicating ourselves to advancing energy transformation through high-performance products. Each new product embodies our team’s relentless pursuit of technical excellence. Our goal is to remain at the forefront of innovation, discovering and validating technological breakthroughs, thereby bringing more reliable products to the market and bridging the gap between cutting-edge technology and end consumers.
We are open for inquiries for any 26650 battery packs as well.
