Please, anyone who has lithium Spot-welding tool for sale, kindly quote me.

I want to start building lithium walls like my bosses dollarnaira , officialfestus , pennuel (not sure I got that right) and others whose name is a tremendous task to spell out grin

Any local (Nigerian) source to buy reliable lithium cells will be appreciated.

Yes boss, like placing two or more cells side by side and soldering the metallic connection at the top and button of the cells

You need cell holders first. Then welding.

For welding, you could either go for soldering or spot welding. You can get away with soldering the negative side but extreme care and right tools is required to solder the Positive side.

wouldn't advise that you play with li-ion cells unless you know what you are doing, it is also a labour intensive task to couple 300+ cells. This was the one I built about 3 years ago, 3s 250ah and 7s 120ah
How much will you build for 50ah 12v? With a charger
I no wan burn ❤️‍🔥 house

The positive terminal is exactly my concern. From experience,it's easy to melt up the insulating plastic at the positive terminal due to prolonged heat from soldering.

Spot welding solves that problem by providing instant attachment within a second hence, the need to learn your DIY spot welding

Soldering is for experienced builders especially with the right soldering iron and lead.

Spot welding is good too but its materials are not easily reachable.

You hardly see a seller of spot welder not to talk of the strip around. But you will get soldering iron and lead just along your street.
