I bought one last year and it seemed a bit too simple and cheap looking at the other kits that are available with relays and connectors n stuff but it seems to work very well. No complicated or extra wiring or bits.
I looked at these items when I was planning my install. I wasn't sure it was that simple to fit.
I didn't know if it needed cables going to the alternator or other items. That was why I went for the dual sense 125amp VSR. Very simple to fit. Gives me the option to charge the batteries from the alternator (when driving) & from the battery charger (when hooked up).
Zmok, im looking at this split charge relay, what kind of situation do you mean when you say "when you need to switch more amps", is that for when using higher amp equipment connected to the leisure battery ?
Can the smartcom be permanently wired to a 70a relay and still work as it should ?
For example if you use a large inverter and flatten the leisure battery - Then start the vehicle with the inverter on. curent will flow down your split charge wiring at around 70a to power your inverter.
If you're leisure battery like mine has a coupe of lights and a fridge connected to it then use just the smart com and all will be fine.
If you use a 70a relay then just use the smartcom as the trigger for the relay then you dont need to find any alternator wiring.
