Hello,
Observations and astonishments
I've been trying to understand the temperature rises on the DC cable (multi <-> batt) for a while now. So I tried with 50mm² and 95mm² just in case I was a little stingy on the section and caused an "incompetence" warm-up ;)
But different cables and identical results: The VICTRON 275 A battery switch causes a throttling which causes the cable to overheat, supporting thermal photos:
1. Photo with VICTRON Switch (48V/100A)
2. Photo without Switch, terminals directly connected (48V/100A)
Can anyone tell me what's going on? Dead switch? Normal?
PS: the little wire on the terminal is just a temperature probe
