Hi all,
my first attempt to put together some batteries, so please be helpful and kind.
I was looking to replace a 12V 7Ah SLA battery and found ready made batteries but with low Power or other issues.
This should replace a standard 12V 7Ah SLA battery and has eight 32700 6Ah LiFePo4 batteries in a 4S 2P configuration resulting in 14.4V 12Ah.
It has a simple "smart" BMS and fits tightly in the same footprint/dimensions as the mentioned 12V SLA battery.
Here is the Sketchup drawing

Components
Batteries: 8 x LiFePo4 32700 3,2v 6Ah
BMS: Daly Smart BMS R05T1-Gl19, 4S, "12V", 30A
Some 2mm sheet LASER CNC'd
Alternately the case of an old SLA battery + Credit Cards as separators
I hope to learn from your kind actionable and constructive inputs, I am then looking to LASER CNC some 2mm thick plastic sheet somewhere.
Depending if it's not OK to solder right onto the batteries, I might need to borrow or go to a place for a point welder also.
Thank you all!
