What Amps are required in a Dual Battert Systen

[gfm_69]

Are there any budding "sparkies" out there. I am considering buying a 'PROJECTA 150 AMP ELECTRONIC 4WD DUAL BATTERY KIT and my question is do I need the 150 amps or will a 100 AMP kit do? There can be up to $80 saving. All the system will do is run a Engal 40 lt fridge and charge a LED camping light.
Any help would be great.

Cheers

mate a 100amp kit will be fine as you will find that your alternator is only rated to about a max of 80 amp, im using a 100amp red arc isolator and it works a treat.

^^^What he said - 100Amp redarc here too and it manages my 100aH AGM's and the 110L Waeco just fine... Just make sure you go as big as practicable in wire size to maximise efficiency and reduce voltage drop...

110L Waeco? I thought my 60l was big You must be a thirsty man, Blue

Nah mate, the missus loves her fresh salad stuff and fruit for the kids when we go away - in hind sight, I should have bought 2 x 50L but that's another story...

Blue - Ive been debating whether to go one big one or two smaller ones. Whats your thoughts behind two ? Is it one fridge one freezer ? Ive seen the Waecos with a freezer/fridge component in the one unit -they come in 50L an 80L size, but I have no idea how well the freezing component works in them. Would hate to buy one and find out the kids ice blocks melt

In future I want to get a camper trailer (where I could put another fridge),so thats why Im tossing it all up. Im also not sure if mose camper trailers would fit a bigger size fridge in them to be able to slide out.
