Well some bad news on this battery backup it bit the big one

We had a bad thunderstorm yesterday afternoon ( the power blinked on and off a bunch of times in a row ) and now it does not charge the batteries no more ( also the fan does not run either ) you can get the green to come on but if you turn on the power supply back on a couple of minutes later it goes into shutdown mode and the battery replace is flashing and there is no inverter function that is working

To many issues with it this time around

I am not going to try to repair it again I can not find any obvious damage but to me it not worth the time or the effort to try to fix it again
