What to do with my Kubota 7.5k

[mchero]

I have a 3 cylinder Kubota under the font of my 93 Pace. When I'm in a CG with full hookups charging the batts is not an issue.

When boondocking I need to Charge the batteries via a generator. The Kubota is VERY noisy, I hate to run it for more than an hour.

I normally use a Honda EU1000i to charge my 4 Sams Club 6v golf cart batts via a P.D. 60amp converter with charge wizzard.

Is it possible to get a MUCH larger converter to charge my batteries? If I can fire up the Kubota for perhapsd an hour or so that would be great. I just don't know how fast and/or how much of a charge these batts can take.

I do know that I have NO room in my battery compartment for AGM's.



Ideas?

Thanks

How many amps can you pump in? The typical rule of thumb for frequent charging is 10% of Ah ratting. Your set of 4 GC should be about 440 Ah so that would be 44 amps of charge current. In the interest of shortening gen. run time I would say doubling that would be plenty so that puts you at about an 80 amp charger. There won't be much advantage, nor is it advisable, to go any larger.

Most chargers will only reach full current output in the middle range of your battery voltage, and will taper off as the batteries get charged. For that purpose, charging from your onboard could best be done in the middle range, and you will keep the noisy beast to a minimum, but perhaps twice a day if required.

I would reckon you could get 80 - 100 amps in, but again, only when the battery is in the proper range for full charge current.

Oh yah, you don't have to tell me the EU1000i is a stretch, If the batts are deeply discharged the EU100i will not handel it.

Just wondering how much amps I can pump into these batteries.

Prior poster was asking where the batteries are. I have a battery compartment on the curbside, last compartment back. I have a pull out try with 4 Sam's Club golf cart batteries. Very thick cables running to batteries. I need to take a closer look at ther PD, located under the bed. I can't recall the wire size from converter to batteries.

Thanks for the info so far.

You can a little by going to the 80 amp PD unit. You would gain a little.

Where are your batteries locted in your rig. My gas Pace is located in front. Wire size and voltage drop could reduce your charge rate if they are located some distance from your converter.
Have you checked with Kabota dealer to see if your genset is abnormably noisy?
