I don't think you understand what my intent is. It is not connected to the battery. It is connected to the alternator fuse box. This is a mere data driven wire to tell MPPT to turn on or not based on whenever the alternator is running. It only needs 16-18awg wire, nothing more, nothing less as...

50A. I am considering returning it and get 30A. I have a weird feeling that 50A might be too much. I did upgrade my alternator from 105A to 145A. It is smooth like butter, and it idles exactly like 105A alternator. Crazy. Glad I found a good quality alternator. So it should handle the load...

Thank you! That's exactly the answer I need. I'll come back with results in the next day or two.

Under the hood, in my engine fuse compartment box, there are three different fuses that has Ignition label on it. I am not sure which one is a proper to use. I prefer not to connect to the alternator as it would void my alternator warranty if I splice the cable. Plus, I plan adding a manual...

Good to know that. I had have been confused how BMS indicate which cell is the first one. It's staring to make sense now. It's actually .1 volt apart. So cell 1-2 are at 3.50, and cell 3-4 are at 3.60. That's why I ended up typing 3.5, and 3.6. ;) I did a capacity test down to 50 percent. I...

Yup. It's completed and it's .1 volt difference. I'm going do a capacity test to see which hits the bottom first. Then figure out how to deal this mismatching cells. Oops, I didn't mean to post this. It was suppose to go to another post (edited post). Sorry for the spam.

Forgot to mention that the current amp/watt rate still hasn't hit zero. It's at .07amp. I been periodically checking every half hour with my volt meter. Cell 3 and 4 still hasn't went over 3.6* volts. So maybe it's still a good sign that it's still balancing.

Alright, It finally got to 3.6 volts. I did it via parallel. Not individual. I don't want to push it to 3.65, there's no reason to do so. I did some studies and some recommended 3.55 or 3.6v to keep it on safe side and not put too much pressure on the cells themselves. Cell 1 is the...

I mean, if they are like .2 volts difference, then it's making my life way more difficult. Initially, it was the same, and went out of control. I guess, I'll have to suffer and plow it through. Manually go through each cell to make it at 3.5v, then set up in parallel them to 3.6v. Is this a...

Soo Should I just stop and put them in parallel at this point? I don't want to wait two weeks just to top balance it. >.>

I got my benchmark Power Supply. All of the cells started at 3.28v I been running for two days now through serial connection to speed up. Now there is a huge difference in voltage based on my BMS. I try make sure they are not over .15 volt. It happened. It was .235 volts difference. I stop...

I guess the general rule is that anybody who gets new batteries, and they're all in the same voltage, one should still top balance it? Thanks for the links. I'll order benchmark power supply.

Hello, I recently acquired 4 - 3.2v 280amp (EVE), with overkill BMS. I also got NOCO Genius 10amp 12v battery charger. The overkill setup is default. The only changes I put in is the capacity (280amp), and cycle capacity(224amp). I don't understand cycle capacity. I don't want the battery...
