So got a couple more bits to add on
2 enclosure
1 custom fibre glass enclosure has a bunch of holes in which could be epoxied not for any specific deck Andy pretty much nearly flat (teeny bit of concave) holes where meant for power button phase wires And voltage display
Around 15cm by 40cm by 4.5cm (£10)
Next got a @bigben 9two5 enclosure with also a bunch of hole so in sameness thing could be epoxied or left as is the holes are for phase cable power button and voltage display (£20) sold
Old meepo Samsung 22p battery with new bms and xt90 connector plus fused charge port
Doesn’t output much as very old but could be used for either a small build or for testing (£20)
