There was a surplus company here in SoCal selling brand new in sealed box 100 amp Renogy Smart Lithium batteries for 300.00 then 325.00 . I bought two of them and have had zero problems so far. They’ve been installed in my trailer for about 3 months now. A friend of mine picked one up too and...

Hello all, Ive got several lithium ion packs made of 18650s. Occasionally they will go offline due to being at or below the minimum voltage per the BMS. At this point they will not take a charge either. If I read the voltage on the output side of the BMS it’s essentially 0 volts. On the Input...

I asked Wil the same question after the review of the smart battery but he wouldn’t answer the question.

I had a similar issue. What I found is don’t press and hold the activation button. Press and release it quickly one time. Thats all it took for me. Also, make sure you are using the correct port. Initially the button should be a dim blue. Once activated it is brighter. I also bought the remote...

Nope, I bought two of them and they gave me a price break for buying several items. They are in factory sealed boxes. Not labeled “AGM“ I picked them off of the pallet myself. Opened them up to inspect them before I bought them. They have some cool stuff there. (While supplies last). I picked...

Does anyone know if these will work in any orientation? Might be a neat project for a window a/c unit. Don

I recently picked up two of them NIB one for 300 and the other for 325. They work fine.

Just to add to this, I purchased a radio from a Chinese manufacturer. The radio had a lot of problems and the software to program it was terrible. I gave an honest review stating all of the problems I had encountered. I received a rather colorful response from the Chinese seller asking me to...

Do a search on this site. https://diysolarforum.com/threads/what’s-inside-of-an-aims-12v100ah-lifepo4-battery-have-a-look.4230/ I would recommend a different vendor based upon my experience.

Had a similar problem with my battery. Different brand but was a failed BMS. I replaced the BMS and now it’s fine.

Actually not, mine failed in 6 months and they wouldn’t return phone calls or emails. They did not stand behind any kind of warranty. I ended up repairing the battery on my own by replacing the BMS and new case. Once I opened it they would not do anything. That part is understandable. I spent a...

You might want to search this site and look at some of the reviews. https://diysolarforum.com/threads/what’s-inside-of-an-aims-12v100ah-lifepo4-battery-have-a-look.4230/ and here...

Thanks everyone.. that helps to understand.

If the battery pack already has a BMS why do I need an SCC? Isn’t the purpose of the BMS to protect the battery from over charge and over discharge? In the past I have used a regular bench power supply to charge battery packs with a BMS. I did not have a CV CC supply. I have used a Harbor...
