Hi everyone!!
I’m currently converting a 2006 Dodge Sprinter, ex Fedex fleet. I’m on the electrical stage of my van conversion and am a little confused on what to buy for the battery to battery charger according to my battery and alternator.
I’ve estimated I’d use around 72Ah per day (fan has to run pretty consistently as I have a dog and cat). I’m using the Far Out Ride electrical guide. Their calculator says I should have a 220-240Ah battery. I’m going to go with a Renogy 200Ah battery since that’s what I can afford in my budget.
Instead of an isolator I’m going to use a battery to battery (dc to dc) charger. I will hook that up to the alternator. The Far Out Ride calculator suggested I use up to 40A charger based on my battery and alternator. I have a 150A alternator and am likely going to upgrade to a 200A alternator within the next couple weeks.
My question is -
Is the 40A battery to battery charger okay to use based on the alternator power and the battery? What is the difference in charge driving/idling time with a 40A battery to battery charger vs a 20A?
I won’t be running solar right now due to budget limitations but plan on it in the future.
Any help is appreciated and I hope I’m posting in the right place! ☺
