Full MB56 Battery Test - Auto Top-Balance, Infrared- and Capacity test. Do we get 34kWh?

Video Description

We are testing the huge MB56 battery from Yixiang with supposedly 34kWh of stored energy! Before we can do the capacity test, I had to fully charge this battery and this alone was a bit of a challenge. Because I set the BMS wrong, it took over a week to charge it from solar. At 09:08 I show you how to automatically top balance this big battery just with the JK-BMS and an adjustable power supply. Very simple and convenient. I also believe, this is the fasted way to balance a new battery. I then had to come up with a way to use both inverters at the same time to get a discharge current of around 100A. There was a bit of setup necessary to get there, but eventually, it all worked out. We also measure the loss at the fuse and breaker at 100A as well explore the battery with an infrared camera while discharging.
