Leisure battery advice - 100 or 80 amp?

hi...on my first conversion and keeping it quite basic, only planning to run 4/5 led lights and a stereo off the leisure battery, as well as charging mobile phones. I don't want to put too much strain on the alternator - would an 80 amp be enough?

cheers

depends what watts and volts the lights are and how long you plan to use them will dig a chart out i got later when get more timeT:

With that limited set up you could probably run it off a standard car battery.

Depends how long you intend to run the set up stationary. bigger battery/more AMPs longer it will run betwen "fill ups"

85 amp one has always been fine for us - lights, stereo, 12v tv etc. All depends how long you want it to run without charging, should be fine for a long weekend T:

Hi as a rule of thumb bigger is best as it will have more reserve and what you are going to run is very low on consumption so you will be fine with 80-100 amp! you can have a crossover unit fitted to the battory supply and this will automaticaly keep your leisure battory topped up when you are driving ( not to expensive to buy diy from towsure ).

110AH. Can be had cheap. If you are going to put in all the wiring and split charge relay, may as well get a decent battery. After all, later you may wish to add an inverter etc.

Use decent cable. I stripped out and re-wired my motorhome as the factory wiring was getting HOT and I only got 11v at the back! 12v requires thick cable to avoid voltage drop, I used flexible 70a cable and 100a split charge with a 50a fuse.

It won't tickle the alternator, the only difference is how long they take to charge. Your alternator will still kick out 14.4v just fine.
