Got an electric bike? No doubt it came with a charger. Eventually, you'll need another charger, since they sometimes burn out. What's in that expensive box? The core of a charger for Lithium batteries is called a CC(Constant Current)/CV (Constant Voltage) power supply. These will create a constant current, limited by a set constant voltage. A common and well respected brand is Mean Well (there are many others) and this instructable focuses on the Mean Well NES-350 power supply. Why be so specific? Some modifications are in order to make this into a good charger for your electric bike. We'll focus on this specific model and diagram some mods that will make it work.

A good charger is needed along with a good Battery Management System (BMS) to keep each cell for over charging, the number 1 killer of a battery. But a good BMS will also keep you from deep discharging those batteries too.
Thanks for posting these.
