Hi, I am looking into building a 18650 charger/tester. I am thinking of something like a 16 cell tester or something. From what I have researched I have seen most people using an arduino as the controller. The problem is the I have never written code for an arduino and so the code would probably have to be already written. I do have some experience with hardware though, but I would be interested in something that is designed already and that I could just build off a schematic.
So basically, a tester that has the code and software ready to download and the schematic designed for the hardware.
Any suggestions?
 
Honestly, just get some off the shelf Lithium C/D/C chargers like the Liitokala Li-500 or the Opus.
I got 7 chargers, totalling 28 bays for just 100€ and dont have to bother with the whole pcb design, calibrating & writing software stuff.

16 Cell 18650 Charger/Discharger Board Module

Inspired by many sources. One of the first videos I came across that piqued my interest was Brett's :) Who happens to be a kiwi too, Bro ;) Other videos of interest. A big caveat, I am no electrical engineer. The layout and track routing probably break all sorts of best practices. My...

Mass Capacity Tester

Hey guys, I like the idea of these mass diy capacity testers. I am capeable of soldering bits and pieces and can flash an esp8266 with espeasy but my programming skills are totally non existent. Can someone design a lets say 20 cell capacity tester based on arduino as a standard layout to be...

Brett's Arduino 8x Smart Charger / Discharger

Hey all, Just thought I would start a new thread. Finally I have had some success on building my newprototype 18560 charger / discharger. I am using 3.3ohm resistors for the discharge,TP4056 modules to charge and it is controlled by an Arduino Megamicro controller. My first manufacturedPCB...

Charge/Discharge station with SBC (Orange/Raspberry PI)

Hi, Inspired byFrescaand MrConstantinprojectsI've decided to make a newcharger/discharger station, but using with different approach. My goal isto control and visualize whole process of battery testingwith a single-board computer. There is now a large selection of models,they are cheap...

FCDS - FERCSA's charger/discharger station. (MM giveaway inside!)

Hi! In the last few months I built my own laptop(yes and it's working great!) and I thought it's gonna be fun if I made a arduino based battery pack for it. Until then I'm using a smbus based panel from a salvaged x60 battery. I know it has a lot of feature I'm mean a lot.. but heey where is...

Constantin PowerWall

Hi, I am Constantin from Romania, and i will start the first PowerWall project. I wish to make an modular PowerWall system for easy upgrading. I will use 18650 Li-Ion Recycled battery buy-it from dismantling company. For the frame i will use BOSH x shapealuminiu modular frame...

And this is why I love this forum because I don't have to reinvent the wheel and can iterate on others work instead :) Now I just need to find a forum community like this for PCB design/esp32 coding/smarthome projects.

Yeah I like GitHub but does it have a social platform just for connecting in a less technical project specific way?
