I just got my 280ah AliExpress cells in the mail today. They look immaculate and Im in the process of bottom balancing them now. I'm incorporating them into my short bus skoolie build. I had some questions on fb and they pointed me here. I have 8 cells and want to build a 24v system. My power...

In getting ready to tear into the interior of my bus to redo it. This requires basically everything on the inside being stripped. I have 8 lifepo4 cells with an overkill bms. The batteries will need to be disconnected for a month or two. What's the best way to store them? Bms still connected...

Long time no talk, which is a good thing because my solar has been running flawlessly. However I have the opportunity to purchase a 2015 Nissan leaf EV for next to nothing. There are almost zero details on the vehicle other than it seems to be in very good condition. It is a police impound...

I have been charging my 24v system 8 cell system via a generator as my charge controller went out. I have a power supply plugged into the generator and the power supply ground lead hooked into where the BMS ground would go into the charge controller. Positive going to the main positive on the...

#1 Installing epever 4215n. Long story short I fried my old controller due to a residual charge in the panels. It's a very cloudy day today and it's still showing 110v from my panels. When the sun sets should the voltages level off so I can install? If not what's a safe way to clear that charge...

I bought a charger that takes way too long to charge to 3.65 v. I think it's been on the charger for about ten days and it's only at 3.37ish. I set it to CC instead of CV to get it to charge quicker. I checked it this afternoon and it was at 3.7, yikes. Pulled it off the charger and after a bit...

I live in my bus half the year, other half is in a regular house. I run a 24v system with epever mppt charge controller, 900w in panels, current connected bms. 8x eve 3.2 v cells. I stay in southern California during the winter so sunshine generally isn't a problem. Last year I was able to run...

I have my BMS all setup and ready to go. It's 8s 24v diy pack with the standard 280ah cells. I have been testing it inside before installing it in my bus. I just get around to putting on the charge controller. Imagine my surprise when the charge only read 14/15v? I have 30v going into the charge...

So I was on the road and exhausted. Like 10 hours of sleep over a week. Wasn't paying attention for a few minutes and I think I made a couple of errors. It's possible the controller was bad but I'm not sure. I have 3 "SSX-315M-BLK-120-NEW Q-Cells 315W Solar Panels, Black" panels. The charge...
