Tesla fuses make sense with tesla cell which have no PTC, CID protection. Here In 20p It may be worth it, but if one cell fails it will (90%) not blow the fuse, just slowly take down all other paralel cells. Fuse will blow only if you mechanicaly damage some cells. Then it will save you.
Your battery, motor and this controller
Should be ok even for 80A short peaks, but you will have to change controller power wires and traces. + add capacitors.
72v LCD3 here:
I will get commission credit if you buy through the links
@Casainho - this controller has the same board number as bms s12xx only difference is the 12 / 18.
Works for me easily with main branch. Only issue is wrong power measurement which you can correct by soldering your second shunt back and testing. And adding shunt number option to java app.
Here with 72v may be problem with lvc (same will be with bmsbattery controller) can be corrected by changing one smd resistor to the same which 48v version uses, or by firmware option.
Anyway you should add lvc setting not depending on liion cell number set. Some people use 2.5v, some use 3.2v.
