lipo-chargerRecently I bought a SKYRC iMAX B6 Mini charger. At around $35 this charger is affordable and feature rich. The build is solid and it works flawlessly. Ability to charge different types of batteries is a big plus.

However, there was one little problem. The adapter connector’s inner barrel is 2.5mm size. I did not want to spend extra money on the adapter as I had a couple suitable adapters at hand. However, those adapters have barrels with inner size of 2.1mm. Moreover, getting an adapter with a 2.5mm barrel size turned out quite tricky. And don’t try to push 2.1mm on this. It won’t work and you will damage the device.

lipo-charger-2With a little hack, this problem was solved. I bought 2.5mm connectors and used it with one of my adapters.
This charger can charge from 1S to 6S LiPo batteries. Of course you need an appropriate adapter as well. The one that I used is 12V with 5A output. You can use an adapter with lower amps depending on your battery.

One final thing. You need to provide positive voltage in the center of the connector. So, make sure to solder the adapter wires appropriately.
