Is it possible to install the victron cyrix 120A on a 2007 mercedes sprinter ? and what gauge of wire should be used ? thank you !
Yes. But the question is what you want to do with it? I've seen someone refer to it as a charger in his install videos and it certainly is not a charger. Wire size as always, bigger is better but depends on circumstances.
I want to use it to charge my leisure battery when the engine is running. I thought it was what it is intended for no? thanks !
If the 2nd battery is also a lead battery you can use the cyrix an I would recommend a wire of at least 35mm² or 50mm²(I don't know the AWG number).
But if the 2nd battery is a lithium battery you should use a DCDC-charger.
I will not use lithium. will it work even if my alternator is pushing more amps than 120 ?
If the alternator can deliver more than 120A you should use the 230A cyrix.
