Advice on Battery charger

I don't have a MH yet, waiting for my boat to sell. I installed a 100 amp Charles marine grade 3 bank battery charger in my boat that costs about $1300. I'm thinking of removing it from the boat to use in my future DP. I know any DP I buy will have a batt charger, but the Charles charger is high quality with a lot of capacity.

It will be a bit of an effort to remove, but will if it's worth it. What do you guys think?

Most motorhomes come equipped with a 3 or 4 stage charger of high quality. Not sure the juice is worth the squeeze. At least not until you know what any future MH already has in it.

The largest converter / charger output amps that is recommended for battery charging by lead-acid battery manufacturers is based on the rule C/3 where C is the battery bank Amp-hours. A typical low or mid range MH will have 160 AH or so. Your MH will already have a OEM 45 or 55 AH converter / charger.

If you are planning to add more batteries to the MH then the bigger converter / charger would be useful to replace the OEM one.

Many Class A diesel pushers have 3 or 4 stage, 100-120 amp inverter/chargers. Lower end models are more likely to be in the 50-60 amp range.

I think if you think your boat will sell without that $1300 100 amp Charles marine grade 3 bank battery charger in it....remove it.
(But it's your boat and your charger...only you can decide what's best for you).

As Gary noted, most DPs in the size you are getting, will have an inverter/charger appropriate for that vehicle. From your post it sounds like you have a charger only, if so, you would some how have to add a 2000 or 2800 watt inverter. I'd leave it in the boat, as a selling point, your future DP should be fine with the OEM equipment.
