Well everyone I am pleased to say that this APC UPS BR1500G is fixed! It put up quite a fight!  :box:
Can't thank you guys enough for all the help.  Could not have fixed it without everyone's input!
Great, good work! It's a pleasure to hear about one more repaired device!  :-+

Awesome, glad to see you fixed it in the end!! A dead GPIO pin huh - who would've thought of that when presented with an "AVR relay weld fault"!

Repairs certainly are a great way to learn: IMO there is no better way to learn about electronics than to solve real problems like this, and see first-hand all the weird stuff that actually happens in circuits. Plus, who doesn't love a good mystery!

Thank you again RLP - you were so helpful to me during this repair.  I learned a lot from you! I really appreciate it!  Same to you Vovk_Z and others!

Great! Could you attach the firmware?
Other people might not get so lucky when reading the stm32 (Broken, protected...).

Absolutely! Once I get back in the lab Monday I'll attach in a post!

So sorry David! I was on PTO most of this week.  Going into the lab today - I definitely won't forget.  I'll have it up by tonight  :)

This saved another APC from the scrap, Thanks you did all the hard work for me. I had another project going on so a small order of some STM chips made sense for a few bucks and boom there you have it. shot in the dark repair hahaha

I would like to know how i could change the charging voltage, so that i can raise it up to 14.4v/14.6v. I replaced the batteries on my BR1500G but batteries only gets charged up to about 50% and i only get 50% usable power out of them.....

i replaced my SLAs with LiFePO4 batteries. I also want to connect an external 12v 100ah battery do that i can stay charged for a while when power outages happen here in venezuela.

i am trying to find the "smart" communication on my BR1500G but to no avail.

If anyone can confirm whether the smart communication protocol is available on the BR1500G, or maybe do i need to de-solder the resistor with a different value on the feedback voltage divider as ChatGPT is telling me to do so. ;).

I got two BR1500G, and plan to use it and not waste them. Plus I think if we can use these with LiFePO4 batteries, we can have extra life ou of them.
