So a quick update, I started out building 12v packs for water pumps as I live in the driest state ( SA ) in the driest continent ( Oz ). long story short now I'm building mainly 24v packs for fridges ( 12/24/240 V ), Air Compressors both 12v and 24v, LED lighting etc.

Started with 1865 and now moved onto 2170 Tesla ( 3 and X ) cells, looking to get into LTOs.

Here is my orig. 2170 24v ( 29.4 ) - 1st attachment

Prototype Power Pack 2170 cells - 2nd attachment

I have 40+ years experience as a Soft. Eng. and have now got soft. ( using sockets ) to email when a cell in a pack is now 'sub-optimal'

I have been working thru. ppls issues with family and friends and now I have been asked to provide a pack that can start a car.

I already provide Volt Regs. to drop from 24V to 12V, so I'm guessing I need to have a reg. that allow the AMPs ( CCA ) to be adjusted, but I cannot find any on Amazon, eBay or Ali :(

Anyone built a 1865 or 2170 CCA adjustable pack ?

TIA
