Drone Charger E3

If you are looking for the absolute cheapest 2s lipo balance battery charger that still works well the E3 is your best bet. It is super easy to use, just plug into a plug socket, and connect your 2 cell lipo charger balance lead and it will start charging. The only downside is that it has only 11W of power so you can charge at a maximum of 1A, so this limits the charger to Lipo Batteries less than 3500Mah, otherwise you will end up waiting several hours to charge your battery.

Note: It's also worth noting that there are some considerably cheaper chargers around like the Imax B3 chargers, but I would suggest you avoid these as they have a history having problems (possibly due to many fake chargers on the market) and are not very accurate in terms of voltage monitoring and cell balancing which will ultimately result in your battery degrading faster.
