1,000 cells to start. What do you guys think 14s70p?[Image: 2880248129bc266f1824a47af1216ea5.jpg]

Sounds good to me. 14s gives you the best options for wiring. Though, the inverters are a bit limited for the US market. That is, UL-listed and certified. Plenty of Chinese inverters that will work, they just aren't certified. Which may not be a problem.
The larger the pack, the more each pack can store. However, that kinda dictates what you want to build.

That's right! Hell of a deal. Any tips? These little tabs are slicing the hell out of my fingers. I need to be more careful

Get a pair of small snips and cut the tabs first before trying to pull them apart. And actually, several others just snipped off as much of the tab as possible and left the welded portion on the cell. Some of the welds can be so tight that they actually rip a hole in the Neg side of the cell.

I have an icharger 106b+ should i charge each one of these up individually or can i buy/build a cradle to balance charge multiple cells like a lipo?

also, can i rename this thread? since its linked to my profile i should probably give it a name

You can rename it.

You can parallel many cells on came and charge. Balance charge them generally takes longer time. So if you have tons of cells at same voltage just parallel charge them all if they are from same batch. Then you can do the discharge test one by one afterwards.

Thanks! Been watching your transfer switch contactor videos.. would that transfer fast enough to keep most things on? Or do you find your appliances blinking 12:00 very often?
