XTAR Chargers Provide Support to 20700/21700 Batteries
Published in 2018-12-28 Come from XTAR

With the actively support from famous battery companies like Sanyo, Samsung, LG, we’re able to see more and more 20700/21700 coming into our sight, like Tesla Model 3 and the electric mountain bikes. 20700/21700 cells are gradually being used in electronic cigarettes and other kinds of products.


People are looking for chargers that can charge 20700/21700 cells, we’ve also been asked whether our chargers can adapt to these cells, since 18650 cells can no longer satisfy their needs. Actually we’ve predicted the popularity of 20700/21700 cells before manufacturing. Here’s our previous article introducing 20700/21700 cells, and their differences compared with 18650 cells: click me



·XTAR Battery Chargers Provide Support to 20700/21700 Batteries

    With 70mm height, 20700/21700 cells are the tallest common used Li-ion batteries in the market now. With highly adjustable slots, all of the XTAR chargers are capable of charging flat top 20700/21700 cells, except for XP1 and discontinued WP series. Our upcoming products will provide full support to both flat top and button top 20700/21700 batteries, so no need to worry about your XTAR charger being obsolete.


 ·What’s the Difference Between Flat Top Batteries and Button Top Batteries?

    Same size batteries with different top can be put in to same use, while one has a button-like top and the other doesn’t. The button-like top is actually a protective board that keeps battery from over-discharging. However, for massive energy support, like e-cigarettes, protective boards are not required.
