Which size AC-DC battery charger to get?

[SteMacK]

Starting to plan out the electrical system for my conversion and have my first question (of many no doubt!)

I think I'm going to go for a 100Ah Renogy or Roamer Lithium battery but not sure what size 240v battery charger to get. Have been looking at the Victron ip22 models, either 15A, 20A or 30A but not sure which size will be good enough for my requirements. Realise that the higher amp versions will charge faster but maybe I don't need that. How long would it take to charge this size battery from fully depleted with the different chargers?

Also, is there much between the ip22 / ip65 chargers, mine will be permanently mounted inside the van so seems like the ip22 makes more sense, but maybe I am missing something?

Cheers

IP22 has a fan.

IP65 is water proof.

But same charger via the app...

Size your charger to 20% battery ah + normal loads.


So example, 100ah lithium would be 20ah charger plus, standard camper loads at 10ah (fridge,lights,usb etc).

That gives you a 30A charger required for EHU.

No fan on the 15A IP22. which is the main reason i went for it, apart from it being Victron
15A is plenty IMHO. Ours spends most of its time in "Float".
