Jackery power station issue

[Torek]

Hey guys hopefully one of you guys can help me out with this issue. So I use. A Jackery power station Explorer290 plus
To power aerators for a live well and ironically some how it fell into the live well (saltwater) I let it dry for almost a week. And. I plugged the charger in and it charges fine the display powers on but once I disconnect the charger it loses power to the display and won’t turn back on , I’m knowledgeable with a multi meter and know. The basics when it comes to batteries and battery management systems , so any idea where I can start will be greatly appreciated

Are there separate boards inside or just one circuit board that does all the functions? Can start that trying to isolate what is and isn't working. It's possible the BMS part is letting it charge but trips a protection when not charging or something like that. If it's one big board you would probably have to trace and diagnose things unless there is something that obviously doesn't look right. While not as handy you could always replace the BMS, inverter and charger and rebuilt it. Even go with smaller ones of those if you don't need as much power output.

Thanks for your reply homie , I ended up bypassing the bms and the ac inverter and just use it as a big 12 volt Just gotta monitor it when charging but working fine till now it powerd my live well over 7 hours thank you again for your time
