On mine there is no C-
From BMS,
B- goes to batt negative
P- goes to battle positive with the fuse in between

Are you using your bms for charge and discharge?
I am not sure how to wire it using those ports.
Let’s ask some of the experts

I want to protect the cells as well charge them. So could be charge
Hello, do you recommend this 1000v 10A fuse for charge protection?
Battery is 12s5p molicel p42a. Charger is 50.4v 10A.
Thank you
No, something like this works a lot better.

Thanks for your answer.
Too bad. I live in France
Curious to know why you don’t trust this kind of fuse

Specs? or Quality?
You want the voltage closer to actual voltage being used. Fuses are designed to pop in specific ways based on the voltage

If you get the manufacturer part number from that listing, you can search for them locally.
You can also search for fuses with the same ratings (58V 10A, et cetera).
It’s got way too high of a voltage, and it’s physically very huge and heavy.
Ok thank you

I also have a smaller version.
I made the little bit bigger one to accommodate a better flag connector.

How soon do you need it? If you can wait a couple weeks (I’m out of town at this moment) I’ll send you a 58V one

Google to the rescue…32V
Decent chance of that fuse arcing badly, possibly worse, if it trips. Though it seems some folks use fuses with voltage ratings much too low without problems. Playing with fire (no pun intended) IMO. Best to use a properly rated fuse.
