Hi all,
Finally, I repaired all the damaged batteries. By using the battery internal resistance tester, it can be found that among the batteries that indicate battery damage, there are individual cells with battery internal resistance exceeding 10 milliohms, which is fatal for lipo batteries and belongs to damaged cells. Therefore, all my batteries were taken out to measure their internal resistance, and the batteries with the same internal resistance were recombined. After testing, the effect is very good and the battery is restored as new. In addition, because the damaged cells are not enough to make up 3 batteries, I deliberately found out if there are other cell sizes that can fit in the battery compartment. I found that the cell size of autel evo1 is 85x45x8mm. After searching for a long time, I finally found that the fimi x8 SE 2020 4500ma cell can fit the battery compartment. After 2-3 times of charging and discharging after replacement, the estimated flight time displayed on the remote controller has returned to 26mins, which is the same as a brand new battery. Thanks Autel,thanks for they don't lock the BMS chip,not same as DJI. So I'm happy with all my batteries back to new now. Also need to thanks autel let Evo 1 battery out of sock, Otherwise, I have no motivation to study its battery.
