For the first ‘learner’ LiFePO4 battery I built, I just soldered the pre-tinned sense wires of my BMS to the middle backside of my copper busbars and everything worked out fine.
That battery is obviously one that will be complicated to disassemble if/when that ever becomes necessary and the bus bars that came with my new 280Ah cells are plated and protected by shrink tubing.
So I’m thinking for this bigger battery, I want to go with whatever solution is considered best practice for good connection and easy disassembly.
I see many are using round terminals that can be screwed on by the bolt/nut on top of the budbar.
Are the lead wires being crimped to connectors or washers or is there a better way to form those connections?
I’m generally a fan of soldered connections so is there any reason soldering to a washer made of copper (or whatever metal would be best) and bolting that on top of the busbar would be a bad idea?
Appreciate anyone’s suggestions as to the best way to connect tinned sense leads of a BMS to the cell terminals...
And also on a related note, the stick BMS lead harness had no problem spanning 8 90Ah cells in my small 8S learner battery build, but I doubt the harness will be long enough to span 8 280Ah cells and so will probably need to extend the sense wires.
Is there any source of longer stock 8S harnesses and if not, are there any recommendations on the best way to extend a harness to make it longer (other than extending all leads by the same amount, soldered/connected in the same way, and using the same wire)?
