Molicel 21700 3.6V 4200mAh Li-Ion Cell

Batteries are without a doubt one of the most marvellous gifts that we hobbyists have been ever given, letting us take our projects out into the big wide world so we can show off our inventions, impress friends and family members, or provide some kind of awesome functionality far away from power outlets and other easy power sources. However, for a long time, we didn’t have too many different options available to us, with some of the most popular choices obviously being the classic AA & AAA Batteries or the ever famous Coin Cells – each of which were fantastic for their times. Nowadays though, with more power-hungry projects and a whole new world of available and accessible modules of all different types, it’s becoming painfully obvious that we need powerful batteries for our modern-day projects.

These awesome Molicel 21700 Li-Ion Cells are the answer to that very problem, and are here to provide a beefy 3.6V 4200mAh that modern-day projects need, featuring an incredible 45A continuous output and an impressive power density of 230Wh/kg. This makes them perfect for projects like robots and drones, which of course are quite power-hungry and need that power to be portable to work properly. But of course, as with any other Batteries, you can use these for almost any projects you can imagine, from powering a router during load-shedding to keeping a sensor network up and running for weeks on end. And just like any other batteries, these can be coupled together for even more power, making them as diverse in applications as they are powerful. So if you feel you’ve reached the limit in terms of what classic 18650 Cells can do for your projects, or if you just love the idea of having even more power at your disposal, these Molicel 21700 Li-Ion Cells are an excellent choice that won’t let you down in terms of both reliability and quality.

Please Note: Because of the size of these batteries, it’s important to consider how you plan to charge them before purchasing, since they won’t fit in typical 18650 bays. Furthermore, you may want to take a look through our Battery Charger Modules find a solution that best suits you.
