Protecting BP65 from overcurrent

Hi,

don’t need to protect a bp65 itself from overcurrent or can I use it as a „fuse“? Eg it sits on a rail which has an 80a fuse from the battery and down the BP im running a line which should allow the 65A. If there’s a short / overload I want the BP to shut down the line and not blow the 80A fuse upstream. Do I need a second fuse just before the BP e.g. 60A or am I good with just the main 80A fuse?

Hi,

1.) a Battery Protect is not a fuse.

2.) you have to fuse every wire coming from, or going to the battery accordingly to protect them.

3.) a Battery Protect does have a short circuit and overcurrent protection, but this does not supersede a fuse.

4.) a Battery Protect does have a peak current rating:

5.) see manual for more information:Manual-Smart-Battery-Protect-12V-24V-65-A-100-A--220-A-EN-NL-FR-SV-DE-PT-ES-IT-TR.pdf (victronenergy.de)

No one? At least someone from Victron should know what happens on overload....
