HI
i want to buils a 13s 4p with vtc4
sofar the kwelt spot welderseems the cheapes solid way
with precut purenickel stipes
i want it to be water proof
i have my own bms
i plan to use 2 layers of this 0.15 mm nickel prefab sloted stipes one on top of another for better conductivity ?
ill start with xiongda but i build my battery for long term meaning i want to build it conductive enough to take advantage of the vtc4 cell and potential more amp drawning motor
Good i finnaly found a annpowers on aliex that is told be be reliable about the purety.
thery
i m about to my this 5 p yes 5p13s battery case and only use the 4 first line(ther red rectangle will not be used) for my 4p13s and use the remaining place to place my bms(the bms is where mbs will be) in?1a is this a good setup?
could you look at that and tell me if is is coherent or there is something i forgot.. 1b.
the only negative thing i could say is that by taking the last parallel line, some space(nickel tab circulating the cell in parallel between cell in parallel will be different, is that a big problem?
here is the link to look at the case with nickel, i would take the taller 48v black heighet 435

concretely
Other questions are
2 is it neccessary to have 2 layers of nickel . or maybe a better questions is even if it is not necessary is it harder to do?
3 how to do it do i spot weld the first layer to the cell and then add the 2nd layer and spot weld at the exact same spot?
4when it will be time to connect the blue end positive and negative of the battery to wire, how to weld the copper wire to the nickel? with leed regular heat welder?
