Let’s make a low cost 1-8 cell 18650 Lithium Ion battery charger.
This was just a quick project I came up with to charge 1-8 18650 cells for a very low cost. The mini-USB connector is shaped a bit like the “pin” on a dovetail joint and all I needed to do was cut the “tail” in the base of the battery holder to fit the connector. If you make it a tight fit, no need for any glue. I had to remove a bit of the bottom plastic to clear the components atop the TP4056 charger.
Then all 4 red wires solder to the battery “+” pad and the 4 black wires to the battery “-” pad. I later put a few strips of electrical tape over the exposed wiring to insulate and protect it.
To use, just plug in 1 or more 18650 cells. This charger runs up to 4.2V @ 1A. Each cell you add cuts the per-cell charging current. I mainly use this charger to recharge batteries after I have run a discharge test. So I’ll throw in 4 pairs of cells sitting at about 3V and let them charge at 125mA/cell for a day or so. This way I’m not tying up a balance charger to do this. This charger is also good if you have sub-3V 18650 cells that you want to slowly bring back to see if they hold a charge.
Total cost US$2.33 for the holder and $0.33 for the charger:

I didn’t have much time to make a video today, so I did a quick one on the rechargeable 9V lithium ion batteries with charger I bought a couple months ago. I will do a more detailed video on these batteries later, especially if this video gets a lot of views and likes.
