BTW, I noticed one weird thing when I checked voltages of all 40 cells. The voltages are mostly around 3.58 - 3.59 Volt. But in each pack of 5 cells, the first cell has slightly lower voltage around 3.54 Volt. The lowest one is 3.52 Volt. I hope that all this is within margins of admissible variations. But I am wondering why it always was the first cell in a pack that had a lower voltage.
Sure. I am making pictures of all steps. Will post them at some point. Currently, I am balancing all cells on Eboosted advice. Here is my solution for charging/discharging a single 18650 cell:
This is just two pieces of thick steel wire I found laying around in my house connected by hot glue. Works pretty good. You can use a coat hanger equally well.
My charger has several settings: charge, balance charge, discharge, etc. I set it on āchargeā and on 1s since it is charging only a single cell at a time. This way I donāt need to connect balance lead. I also set it on very low current like 0.4 A.
Just received my Vanguard set and holy shit! The quality is amazing. The price might seem a little steep to some but itās worth every penny. This is will be the last thing to break on my board!
