Lately I have been needing more power to run some of my cars, boats, planes, hovercraft etc and although I have tried to avoid it I have finally started using LiPo batteries.
I was inspired by Julian Ilett's channel to do this LiPo charger board project so check out his channel to see his projects.
Yes, I know my soldering iron is a little big for this sort of work but it is the smallest one I have at the moment. Yes I did say 5 ohm when I meant 5K ohm at one point.
You may spot that the circuit board I used does NOT have battery protection so IF you intend to solder your battery to this charger board as a permanent fitting then you might want to make sure you get one with a protection circuit like this one 5pcs TP4056 with Battery protection LIPO Charger Module Board Micro USB
TP4056 Module R3 (RProg) value for setting the output current
R3
10k 130mA
5K 250
4K 300
3K 400
2K 580
1.66K 690
1.5 K 780
1.33K 900
1.2 K 1000
Taking on board some comments from centrospherecom
The charger doctor is not indicating the actual charge going into the battery it is showing the charge going into the charge board.
I could have used a different resistor if I had one, to get closer to the optimum charging current rate.
Here is Julian Ilett's video that inspired this project

I am not endorsing these products I am just answering the questions people will ask. I suggest you do your own search as the prices and specifications will vary and the links I used will probably be out of date when you come to read this so I now just list the item title and you can cut and paste it into your eBay search. It will probably work on other online stores too.
