How good are the u-solder tags on NKON batteries (30Q)? I didn’t see any fish paper on the positive terminals, but my option for a spot welder is a car battery and some 12v automotive relays in parallel with a basic timing circuit so I’m not sure my welds will be good either.
The enclosure will see heavy mechanical abuse so the cells will too (there is gonna be 15mm between the enclosure and the ground and the axle distance is 32", and I ride over lots of sidewalk edges) so I need the most durable option above all
Between the tags and spotty welding what do you guys recommend?
"Typically one 40Ah 440A battery delivers enough current to get good welds with 0.15mm nickel strips and even 0.25mm nickel strips. For thicker nickel strips maybe you will need bigger battery (max. 800 CCA)
The Welder generates a double pulse, where the first one is 12% of the time of the second one by default. Pulse time of the main pulse is adjustable by the rotary encoder and displayed on the screen in ms so you can exactly adjust the time. Its adjustable from 1 … 100 ms by default. (adjustable up to 500ms in the system menu)"
This seems like a really quality welder. Why don’t more people use this?
Did you end up using the u-solder tags? I’m using NESE for the next build but seeing that NKON will ship with the c-tags on already (for a charge) and the PCBs that are available these days I’m thinking this can be a really good alternative to build a battery pack without a spot welder.
