Installation of Smart Battery Protect 12/24-100A

wiring-plan-v2.jpg



Hi

I don't fully understand the installation of the smart battery protect unit.


For the sake of simplicity I drew up the wiring diagram/plan attached and ommitted the battery protect unit.


Is it designed to protect the vehicle battery or the accommodation (leisure) batteries?


Could anyone please advise on where in the wiring plan the battery protect unit should be installed and its orientation.


The lithium batteries in this installation are: 2no x TN Power Lithium 12V 216Ah Leisure Battery LiFePO4


Thank you for your help.

Dan

@dantmjones it would be a good idea to use a SBP to ensure that your loads connected to the fuse block can be disconnected from the battery, before the batteries BMS shuts down due to low voltage. It can be problematic for users to re-start the battery BMS once it has disconnected.

You could probably set the SBP to disconnect loads at 11v. And program the multi to shut down at 11.6v.

I would use a 200a fuse at the battery. And a 160a breaker between the Lynx and multi. Only use quality breakers.
