I'm attempting to restore this dead lithium battery. This is from a Smart Fortwo electric car, EV. I bought this to use in my DIY powerwall system. However, when I opened up the battery I found it was dead. My heart sank. I didn't know if I would be able to salvage any of it. If you would like to see that video, it's here: • Smart Fortwo Lithium Battery, EV, Damaged! I've had the battery modules on a very low trickle charge. Starting with 0.05 amps, and then moving up to 0.10 amps. I've now paused the charging phase with the cells about 3.5 volts each. This charging was done with DROK buck converter, and a DROK boost converter. Links below. I'm pausing the charging because now I want to determine which cells are good, and which I have to toss out. Now that I've got all the cells about 3.5 volts each, I'm going to equalize each cell, and write down the voltages. I'll come back in a few days to find any cells that are self-discharging (there are some). In a future video I will be cutting out any bad cells. The equalizer (balance) board I'm using is unique. It is moving electricity from high cells to low cells. Most BMS boards I've seen just burn off the extra electricity with resistors as heat. Thanks for watching.
