My estimation is 230ah, so yes very close guess at 220.

I would estimate i have probably $400 in the batteries themselves. I lucked into a bunch of new old stock laptop batteries at an auction purplewave.com. they were from a school district, i got almost 500 brand new batteries for 60 bucks, and sold a laptop screen included for 30, so i guess i paid 30 bucks for half of them and 370 for the other half lol.

So i will say if i had to do it again, i probably wouldn't do it again. Not that i don't love it or I'm not thrilled about it, it was a long project. I learned that tool batteries build better packs, generally, than laptops. Therefore, the batteries get used up more before a part fails, such as the bms board or a thermal sensor.

If you have a connection to aviation or medical batteries using 18650s those were awesome for me. Laptop batteries were my favorite because they're easiest to find and easiest to extract the batteries from the pack.

I invested 110 bucks in a spot welder, and probably 100 bucks in nickel strip, fuses, and flux and solder. The charger was probably 100, and I'll be about 50 or 100 to build a good power supply for it.

However I'll now have a powerwise 2 i can sell, and i can sell the old lead acid batteries for cash. In addition the multitude of bad 18650s i have i have been selling to a contact, as well.
