Thanks! Do you have any tips on how to get this grey fill material out of there?
Hi!
I recovered a battery of ES-400 as well. I also found out how to activate the output, or how to charge it.
So far I just charged the battery with a 54.6V power supply and everything went well. Here's what I now know about this connector:
I now want to try to communicate with the BMS, but I don't have any info to do so. Would you have been able to remove this green paste? If yes, you would have info about the BMS ;) ?
I briefly tried to take the battery out of its hull but without success.
EDIT : Power is cutting of after few seconds when I push more than 20-40 watts. On the screen we can see "error 31"
