Hi,
I am changing from a daly BMS to the JK-B1A20S15P. The JK comes with two open cables each for B- and P- with 10mm2/7 AWG.
So I am thinking about whether it's a good idea to put e.g. the two B- cables in one lug (25mm2 should work).
That would make it easier to connect to the fuse/battery/shunt if there ist only one lug.
If I put a lug on each cable I think that could result in a bad connection e.g. on the fuse/battery/shunt because then there lays one lug on another and maybe the holding screw ist too short. (but the crimping of the lug would be "better")
my pro's for seperate lugs:
my pro's for combined lugs:
How did you solve this and what is the best/prefered way to do it?
best wishes
Peter

my pro's for seperate lugs:
- better(?)/easier crimping for the lug
- more flexibility with placing the bms in the "battery box" (cables can be moved seperate)
- possible bad connection/high resistance laying lug on lug
- connection screws may be too short (e.g. on a LiFePo4 Cell)
- needs more lugs
my pro's for combined lugs:
- easier to connect to fuse/battery/shunt
- "better" connection/less resistance on connection(?)
- needs less lugs
- after crimping the cables-lug-combination is not very "moveable"
- possible bad connection (?) on the lug, because the are two cables in one lug
How did you solve this and what is the best/prefered way to do it?
best wishes
