As far as I've seen(youtube videos) the BMS shouldn't really interfere the balance charger, but I can't really tell that.
As for cables, I pretty much have everything I need and have everything in...

The charger is rated at 80W unless I'm missing something?
It's still rather slow, but I don't have any need for a fast charging.

I'm sorry that's it's so 'blurry', but It's hard to tell without...

You're right, sorry, should've mentioned that.
I'm using 108 NCR18650B batteries rated at an average of 3500 mAh, and they were all balanced to 3.7V before installation.

Balancing a 4S lithium battery

Hey everyone, a friend of mine helped me making a 4S27P lithium battery as I don't have a spot welder, the batteries were at roughly the same voltage, but when I got the battery there is a big...

Well....Not really, According to what I've seen spot welders are usually much much more expensive than that.
But then again, that really depends a lot on what the spot welder requires to do,...

Should I get this spot welder?

Hi, I have some battery pack projects which I'm working on, initially I was looking for a solderless solution, but with time I'm realizing that I'll need to pay a fair price for holders as well, and...

I don't think you understood correctly, the AGM is not related to the engine compartments.

Thanks, in case the AGM battery is full, should I still charge it a day or two every week as it might discharge over time on idle?

Do you have an estimation how long it should take for the AGM...

And is there a fuse I can use to protect the battery from high amps?
Also, since we're not using a diode, is there anything to worry about the car battery draining the AGM battery somehow? I'm not...

Thanks for the comment! I never knew that diode drops the voltage, I guess that because the car voltage when running would probably be around 13.8-14.2V dropping another .7V would not be very good...

Charging AGM battery from car

Hi guys, I decided that I'd want to leave my deep cycle 75AH battery in my car, and make something that will enable me to charge it. At first I thought that I could simply connect it to the car's...

There's really no reason for anyone to plug in a 12v plug into 220v or the other way around, and I would probably also use extra protections to make sure it won't happen.

But generally I just want...

Thanks for the clarification PJmax, that is indeed correct :)
This is what the connectors would look like:

That still doesn't necessarily makes it much better though.

Wiring 12v equipment through wall outlets?

That looked like a really good and easy way to power up my equipment in the...

I don't really need more than 12v though, and the price I'm paying for that doesn't seems to be worthy to me when I could simply use what I already have.

I'm not really sure that a 12v battery with 10AH for a price I could simply get around 40-75AH battery would help me all that much though, and I already have some batteries I could use.

Well actually the batteries should be rather new, most batteries I've checked are with around 4-4.2V, so that's rather good.
