10kwh 18650 Powerwall in Nigeria

Hello, i just join this forum.

I love the idea of using Li-ion batteries to power my inverter instead of the usual Lead acid batteries.

One of my lead acid battery just got bad, and now that i have this knowledge, i don't intend to buy another lead acid battery.

I want to start by harvesting batteries from dead laptop batteries or any other devices using 18650 cells.

Am thinking of a 7s 10p configuration per block.

So with a minimum cell rating of 2000mah, i should be getting 20Ah per battery block at 24V.

That should give me about 480Wh per battery block.

Hope it works out well.

Re your problem of breaking fuse wires, can you use cable ties going through between the cells to hold the busbars in place?
Also I don't know if hot melt glue has been tried before?
 
@lawcomleo and OP
i have to say, you have a great setup there ... its quite a very good build and its quite interesting.
am in Nigeria too and i do relate with the power cuts ..... a similar power build that am looking into is a 4s 30p for nominal 12v system but its charging configurations / parameters are something more of a pickle for me and matching with a corresponding inverter to match it.
