![]() Those thick battery cables do not, and should not be bent into the sharp 90 degree angles in the pic.įor nothing else before the shunt, that means don’t put a load before it, and don’t put a battery fuse before it. Making thick cables for 5/16 posts takes up a lot more room than I expected compared to some of the 14 gauge wire with #10 lugs I’d crimped for fuse boxes before. One of my lessons learned is lug sizing and space. I did urchase a battery temp sensor which plugs into B1 B2. The one pictured is for a second battery system, IMO not necessary. The cable plugging into the shunt at B1 and B2 with a dotted line is an accessory, which is not needed. Plug the cable from the shunt to the battery monitor and THat is all you need to do to monitor a battery. Put the Pos supply cable in the shunt, and then attach the lug to the positive battery post. This battery monitor has built-in bluetooth so you can. This kit is made by Victron, model BMV-712. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.Please note how the current needs to flow through the shunt by basically cutting the thick cable out of the battery negative, crimping two lugs on the wire you just cut. 81K views 4 years ago I'm installing a battery monitor kit into my DIY Powerwall. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.
