Ok, i guess nobody knows if having a float current of half an amp is ok.

Hi, I have an Epever 4129 BN, the version that has to be setup with USER parameters to work with LiFePo4 batteries. Many know the main issue is not being able to turn off the FLOAT charge in the setting, and needing to set them to a state that disables FLOAT or makes it a non-issue. It appears...

Hi Thanks for the information. I think I figured out my problem, or at least one aspect of it. I unplugged my loads from the battery when I was getting about 15 amps, and it jumped up to about 30 amps. It appears some off my current input is being siphoned off by my loads and not being reported...

I have a small off grid setup with six santan 250 watt panels in 2s3p configuration. When I first hooked it up I was getting decent amp output at around 40amps, but a few days later I'm only averaging between 10-20amps. My charge controller is an epever 4125bn and I have a a 280ah lifepo4 24v...

How many and what AH cells are you looking for?

Well, they shipped to my vacation tiny home in Hawaii, so they should ship to Alaska. I'll reach out to her and see what's going on.

I would avoid anything on amazon on Ali, definitely, unless you have a verified reputable dealer. I can't stress that enough. The person you want to contact is known as Amy Sheng. You can find her on here as well. Her email is lifepo4battery@163.com. She/they have a warehouse in Houston, so...

Hi, I did not. I think i had used photographs of peoples shipments to accurately estimate the size. Since I knew the dimensions of the batteries it was easy to estimate the dimensions of packaging. However, I ended up ordering from a reputable dealer here that was able to provide a shipping...

Thanks for sharing this info, as I’m about to hookup the same setup mentioned in this post. It seems like I could set the bms over voltage shutoff to be higher than the charger voltage shutoff to prevent the scenario you’re talking about in your post. With the charger configured to shut off at a...

The 26650 cells are for testing the electronics (bms,shunt,buck converter, disconnect swtich, fuse block). My 280 ah eve cells are in hawaii, the final destination for the box. Im currently in alaska. I am off grid out in hawaii, and will only be there for a month, so I need to verify the setup...

Looks like i need to still fuse the 12v fuse block with a 40 amp fuse.

Here ya go. I have some 26550 lifepo4 cells I’m going to test the electronics with, but I’m waiting on some cell holders to come in the mail. My main batteries are in Hawaii, the boxes final destination. As for placement advice, you’ll need a metal pick to punch holes in the boxes ribs so that...

The original design is the photos I posted in the first post. That's all I had to go by for reference.

Eve/Lishen cells.

Nice, good find. The price is about twice as much as the one I bought though. Also, you'd need to find an alternative way of mounting components, as it has not surfaces to attach zip ties to.
