Hi,
Imagine a scenario where the BMS has triggered the ATD and the Battery protect has opened and disconnected the loads for whatever reason, and I now want to operate a certain load that was blocked by that battery protect, and I have got things running again with maybe a temporary 12v supply from a generator or maybe used an engine start battery, or maybe the BMS is running again but the Battery Protect itself is faulty.
Is it a bad idea to have a manual bypass around the battery protect, which is in normally open state?
I would appreciate everyones thoughts.
Thank you,
Alex
In this scenario it would be removed and you would likely bolt the two pos cables together to get the circuit working again.
Hopefully left some slack in tha cable to do so.
For a temporary override, most campers we set up have the relay on the gx or bmv triggering the remote on the SBP. Easy to override the relay when needed.
Hi,
Thanks for your input. I have actually been seeing this relay trigger thing on Victron Schematics, but have not really understood the benefits and reasons for doing it this way. Below screenshot is for an ATC but I guess its the same.
Could you expand please?
Thanks,
If i am reading that correctly that is the lynx bms used with victron batteries. So unless you have those is not applicable.
The bms on/off is for switching the battery on or off.
The remote on the Battery Protect is a loop just needs to be opened or closed. The lynx shunt has a relay.
Yes, I have lynx bms ng and lithium ng batteries. I do understand that its a loop, or even just a single wire to the H side as the L goes to Neg.
That drawing shows an ATC going to for example a battery protect via the BMS relay, and thats how I understood your comment above about triggering via a relay.
Is this not what you mean with triggering via relay?
Best,
Alex
Awesome.
ATD is the one you want to use definitely.
