Okay, no one's going to write rhymes about how dope their battery charger is, it's true, but without one, your cloud-blowing days are over! If you want to get electricity into those cells, you're going to need the Basen BC-2 battery charger. A two-bay charger from the makers of some of the best batteries out there, the BC-2 has all the protection features you want - bad battery detection, reverse polarity protection - and will accept a broad range of sizes (see below) and chemistries, including Lo-ion, Li-Fe, and NIMH.
Best of all, it supports 2.0A fast charging (single battery only), so if you're in a hurry, it's got your back! And of course it'll charge a pair of batteries at a full 1.0A charge rate, or at a slow and safe 0.5A, for maximum battery lifespan. The Basen BC-2 doesn't stop at just recharging your cylindrical batteries, either: it also includes a 1A USB Type-A port, so you can plug in the included USB cable and charge your USB devices, as well.
- Input: DC5V 2A
- Output Voltage: 4.2V
- Output Current: 2x0.5A / 2x1.0A / 1x2.0A
- USB Output: DC5V/1A
Despite the wide array of protection options, we recommend you never leave batteries - of any kind! - charging unattended. And you should never, never, never use any kind of spacer to fit batteries the charger isn't compatible with: it can damage your batteries, and is extremely dangerous. Just don't do it: #vapesafe!
