I am going to be installing an Onan QD5000 into my race truck motorhome but also want to run off batteries whenever possible ie. overnight and whilst on the road travelling (the generator will be great for big loads i.e tools etc when needed but obviously cant be running all the time and while travelling) we will be running 230v appliances (Fridge, TV, led lighting, microwave, combi boiler, charging phones / laptop).
I am looking for recommendations for batteries to look at and how long would i should expect these to last? agm vs lithium - id rather use agm due to costs. (im not sure what my average consumption will be as i haven't finished building the truck yet) and also what sort of recharge time would i get out of the generator to the batteries.
Adding to the above, what inverter would be best suited? and also are there any other related products i will need / will be of value to have.
thanks in advance.
