Brett's Arduino 8x Smart Charger / Discharger

Thank.
Silviu.

Yes it can be. You don't need to buy USB, Ethernet / WIFI, SD card or headers for them.

Hi brett,

I looked at your design, saw no relays, and was hoping you can share what technique you used to switch between the dummy load and the charger. I'm fairly newb in electronics as my dayjob is a software dev and I was looking for other ways to switch between the TP5100 and the dummy load. I initially planned to use a relay but the problem is I wouldn't have the control to cutoff power from the TP5100 and I'd like to stay away from using additional relays.

Thanks.

I've used basic BJT switches so far. What would prompt the use of MOsfets?

Hi I am using NPN transistor and a P-CHANNEL MOSFET.

Hey best to post help for this on my Facebook group. I am still testing the offline code and I will post the code link soon.

Hi, thanks for sharing, great project.

One question, I have assembled but the temperature sensor does not work in any cell, it only shows zero, which may be failing?

Hi...I wanted to make a smart Arduino powered charger, discharger battery tester that could have a barcode scanner that scanned barcodes on batteries and input all the data into an Online Database Portal. This would allow me to correctly sort and analyze trends in all my reclaimed lithium batteries.
