That's what I was looking for, thanks sorry for the high Jack but this is part of boondocking I think. My progressive surge protector shows amps and volts but only on the 120v legs. My auto leveler shows the battery voltage but its 2 volts higher than my Fluke so don't think its accurate.

Wow...thanks for all the great info. A few notes based on some of the replies...

-Yes the battery (interstate marine) was dealer supplied not factory. My mistake.

-I'm pretty sure 2 6v batteries will fit under the bench seat of the vibe 6501, however they would need to be end to end. So two vented battery boxes may be a tight fit. 2 sealed (agm) 6v batteries would get around the need for venting (and the boxes) but would add $$ to the project.

-Thanks for the recommendations on converters and monitors. I'll check 'em out.

AGM or GelCell batteries depend on proper charging. Never run them lower than 50% charge and don't overcharge them. A good charging system is a must and they will last 2 to 4 times longer than lead acid batteries. Gel Cells are strict on over voltage charges also.

If you can get two batteries to fit please post a picture because I could not figure out a way to do it in my 6501

I am in agreement that more battery power is needed....especially since you only get to USE half the amp hours that you buy. Instead of gettig 6V's (which I like for FOUR battery applications)...I'd suggest true 12V marine deep cycles in whichever size you can get in there...group 31 or 27 preferred to give you around 200 amp hours. (See DEKA/Penn Marine Master with DC in the model #!)

The REASON is that if you have a SINGLE 6V battery failure ...you have O power. With a 12V pair....all you need is one.
Next... you must understand that ALL wet cell batteries are going to be limited to taking BULK charge amps at about 20% of RATED capacity. Thus for a 200amp hour battery bank...any charger over 40 amps will not get you one minute faster charging. So...if you are "refilling a 200amp bank from 1/2 full....i.e. trying to put back 100 amp hours....you'll have about 2 hours of BULK charging to put in 80 amps and than roughly another 2 hours of absorbtion and float charging to get to 100%.
If you want to charge more quickly...you need to move to AGM's which can take AT LEAST 50% of their rated charge in bult mode,,,,which then means you could charge at 100amps on a 200 amp hour bank. You are still faced with a big slow down for the last 20% but you should be able to charge to 100% in about 2 hours.
Suggest that IOTA DLS chargers with SmartIQ feature provide excellent price and performance and are widely available. If you go with AGM's then their DLS90 would be a great choice.
I also prefer the Victron Battery monitor over the Trimetric....but they both perform the same essential functions and no boondocker should be without one or the other if they want to keep their batteries rather than kill them!

I have two 12Volt 100AH batteries paralled (DEKA) for that reason as you said, incase a 6V baterry failure. My dual battery set up has worked really well for us so far. I like the Victron battery monitor in your pic. Nice looking monitor. I haven't install a Solar array on my roof as of yet but probably will in the spring.

I would suggest that people look at the vibe 6501 before they suggest two large batteries. This is a small V noise trailer that does not have room for two large batteries. I have one and tried to but two batteries in but could not get them to fit.

Happy....point taken...but I see a space where they could go.


There is no reason the batteries must remain in the current position. There is no way to do extended boondocking on a 75amp hour battery without constantly running the generator so at least 2 batts are needed for what he wants to do. Look to me like a bit of that storage space needs to be reclaimed!

There you gp, if there's a will there's a way. Then mount a 100 watt solar on the roof to keep them charged. Also there are some nice portable solar charge panel kits out there if you don't want to mount one on the roof.

When im in the woods here in NM and its cold, i just run the genny all night long because thats when the most amp draw happens. It only burns about 1 gallon during the night and my batts stay fairly charged. It takes about three days at 3 amp trickle to get my 12 v batteries (2 of them) topped off after an outing.
