21700 Battery Cell-GSL ENERGY

Since established, GSL has rich experience in the R&D and production of lithium-ion battery products. 21700 battery is one of the hottest selling products among them.

We insist on choosing top-quality cells and safe chemical substances as the materials for manufacturing the products. We perform several tests on each product to ensure superior quality including impact resistance test, dropping test, extrusion test, and so on. Thanks to its stable chemical structure, the product also performs well in the thermal shock test. In addition, to ensure the impact resistance of the product, we place a diameter of 15.8 mm steel rod in the middle of the fully charged battery and then make a hammer with the weight of 10KG fall onto the battery. It turns out there is no explosion or fire. This kind of product is tested to have 4000 cycle of times and is guaranteed to have 100% DOD.

GSL's 21700 battery enjoys wide application in the fields of EV, AVG, robots, solar UPS, solar street led lights, and golf carts. It also has passed the certification of CE, UL, MSDS, and helped us obtain the test report from the National Center For Quality Supervision and Inspection of Battery Products.
