The battery box on the 16 is wedged up front of the propane tanks. I'm not even sure if the larger group 27 will fit in the welded box frame. A little research on my part will give me the answer but I'm still looking for options. Still liking RDM's solution. Seems very adaptable to the type of camping being done. Take them along for boondocking, leave them home for the high falooten full hookup trips. Jamie

I currently have more solar charging capacity (260 watts max) than battery capacity in our 25' CCD with two group 24 gel cells so I plan to acquire a third larger battery for those long late fall and early spring boondocking trips. I will use a 45 amp Anderson Powerpole connector rather than switches and other wires or connectors. I already have one on my batteries to power my amateur radio equipment when I am operating under the awning or at a nearby picnic table. The connectors are polarized so you can't plug them in wrong and I keep it permenantly connected via a 12-inch cable that is curled up inside the battery box until I need it. These connectors are becoming the standard for people that provide communications support to public agencies for public service and emergencies.

You can find the Powerpole connectors from several vendors by searching the web; http://www.andersonpower.com/product...powerpole.html is thwe manufactures web page.

Swapping to 2 6 volt golf cart batteries

Due to their low internal resistance, they only lose about 3% of charge per month, compared to 30+% for lead acid and about 20% for gels.
Couple of questions on swapping to 2 6 volt AGM golf cart batteries:

1> where can you pick these up (e.g. Camping World, Sears)?

2> are there any wiring or other tasks involved for swapping these in?

These questions may be answered on another thread, so I will hunt around as well.

Thanks!

p.s. nice to see this thread start up after my original post in 2004!

The biggest Lifeline that fit my 2006 16' Bambi was the GPL-24T. I called around and I found a number of local distributors that had Lifelines but none that had the GPL-24T in stock. Tri State Battery Online Catalog ended up being both cheaper and easier.

I got a Honda EU1000i to run a Schumaker 3 stage battery charger (2, 20, or 40 Amp). When I want to recharge I power down everything in the trailer that I can switch off, then hook the charger directly to which ever battery setup I have - 20 Amp for the single group 24, and 40 for the 6 volt golf cart batteries. An hour and a half brings the batteries up to 80% or so, and doing it in the middle of the day minimizes the amount I bother other campers with the noise (but it's really pretty quiet).

I also have a Honda EU200i that I got for home to run the furnace or refirigerator in the house when commercial power goes down, but the smaller Honda does the job for camping, and is pretty light weight & fuel efficient. The bigger generator would run the small microwave I take when I go someplace with hookups, but usually when we're camping it's either a campfire or Coleman stove on a picnic table anyway.

Group 27 Battery on 16' Bambi

Jamie
I played around with upgrading the single group 24 to a group 27. I found the 27 will not fit in the same area as the 24, at least if you want to use a battery box. One thing I did try that would work is to position the group 27 battery box long-ways, instead of sidways like the 24. So it sits on the two welded bars, instead of between them. The battery box will fit, but I found the battery cables are not long enough to reach the relocated battery terminals. I looked a long time for a cable stretcher, then considered replacing the original cables with longer ones. The way the cables are routed into the trailer has a large amount of some kind of sealer that would have to be dug out and then replaced, and I didn't want to get into that since the group 24 is OK for my trips with hook ups, and the single group 27 wasn't enough for my boondocking trips, anyway.

If someone has done the job of digging out and replacing that sealer stuff I would like to know how that went - I was afraid I would never get a good seal again. Otherwise, the group 27 would be better than the original, and not very much more weight.
Bob

I have the Honda EU3000i to run the air conditioner. I'm told the 2000 can run the air but is iffy for start up. Rarely use the air so the generator is used like Bob's, during a power outage which we seem to get at least once a year. Jamie

I did put in a new 55amp WFCO converter and I'm pretty happy with its' 3 stage charging, but it's not perfect for AGMs. I have a new charger on order that is actually a 4 stage unit and has selectability between lead-acid/gel/AGM. I'll report back after some experience with the new one.

On another note. Be sure to use the SAME TYPE BATTERY if you are adding a second or third. By that, I mean the same brand, size and rating. Otherwise, you WILL have charging problems.

try to consume less.. change those halogen lamps to LEDS.. makes a huge difference.
a battery inside the Bambi is not a good idea... toxic fumes do escape from batteries.

A generator is an annoyance in my opinion... I hate the sound of them.. even the "silent" ones.. it really ruins camping for me..

Solar panels, on the Bambi's roof there isn't enough space for a decent amount of solar energy.. separate panels... mmmh.. one thief and they're gone.. There are some Photovoltaic panels that can be rolled up and linked to eachother.. so easy to store overnight though... I even thought of incorporating them in the awning.

Or, an expensive, but a solution I'm considering myself, is buying a portable AirGen hydrogene generator.. makes no noise, consumes little..there is another brand...smaller... but I cannot remember the name.. it's an American brand and made for RV's... it automatically tops up the battery if needed, is completely noiseless and needs almost no looking after...

Check out what I did.

http://www.airforums.com/photo...00&userid=4749

I didn't mess with Gr 24 or Gr 27 batteries. I got a heavy-duty sweeper/scrubber battery for my 22' CCD. This should also work on a 16'. The bracket fits in the tight space between the gas cover and jack. The battery has the capacity of 2 1/2 Gr 24 batteries. I also had a cover fabricated for it. Don't forget the PowerPulse desulfator to protect your battery.

More info on scrubber battery set up?

rseagle
That looks like a good setup - can you tell more about:
1) What did you do with the battery cables to make them reach?
2) How did you fabricate that mounting bracket, and any photos?
3) The cover - any more details, or photos?

I never saw a battery like that but it is exactly what is needed for more capacity, permanently mounted - go taller, not wider!

Thanks
Bob

I got tired of trying to deal with one series-24 battery on our Bambi, so I've reinstalled longer battery cables, welded two 15" L brackets 11" apart crosswise in front to the propane to hold an 11"deepX15"wideX12"high plastic box with cover. This will hold 2-24s side-by-side. The cover is held in place with a few stainless screws and I drilled holes in the bottom of the box for the cables. You'll need a couple of additional short cables to connect the two batteries. The box is white and the whole thing looks good. Adds 40# to the tongue weight which hasn't been a problem.

I also changed out the interior lighting to lower wattage (several threads deal with that (search "5 Watt Bulbs in CCD")). Additionally, we carry a Honda 2000 generator which we use sparingly so as not to disturb others.

alternative energy source

Found the info again... SFC A50 is the generator I was thinking of... not for running your Airco.. but for keeping the battery up all the time.
here some basic info from their website:

The SFC A50 is a battery charger based on DMFC (Direct Methanol Fuel Cell) technology. Using Methanol as a fuel, this system offers much higher energy density than Pb-batteries, which are widely used today. The unit delivers up to 100Ah per day (1200Wh per day), operates almost quiet and is very environment friendly. The replacement of an empty fuel cartridge can be done in seconds compared to several hours needed for charging an empty Pb-battery. The SFC A50 is intended to operate in combination with a 12V Pb battery. The battery can provide peak power as well as startup power for the SFC A50 while the SFC A50 offers a significant extension of energy density to the Pb battery.

The Smart Fuel Cell works as a battery charging unit. If the voltage at the connected battery drops below 12.5V for longer then 10 seconds, the SFC A50 automatically initiates the charging process. The charging process of the SFC A50 will be completed and the unit will switch to sand by mode when on of the following conditions occur:
Battery voltage is higher than 14.5V
Battery voltage is over 14V and charging current is less than 1A
Battery has been charged for six hours and the voltage is higher then 12.5V

Complete Data Monitoring Interface includes Live access to SFC A50 internal system parameters e.g. stack voltage, stack current, temperatures. Delivers all necessary information for evaluation, testing and system integration.
Remote battery charger for 12 Volt Pb-batteries whenever solar power, grid power or combustion engine driven generators are not an appropriate solution. Works well with solar for a hybrid solution.

TECHNICAL SPECIFICATIONS

Power: 50W (continuous)
Voltage: 10,5 - 14,5V DC
Ambient Temperature: -20 C to +40 C, -4 F to +104 F
Storage Temperature: +1 C to +45 C
Humidity: 20% - 90%
Fuel Methanol Consumption: 1,3l Methanol/kWh at continuous operation
Noise Emission: less than 40dB(A) at 1m distance during operation
Dimensions: (WxHxD) 380mm x 260mm x 150mm
Weight: App. 6kg (without fuel cartridge)
Electrical Interface: 12V DC output including sense wire to automatically charge 12V Lead Batteries.

Here's a situation almost every RV aficionado is certainly well familiar with: on a holiday journey there is a beautiful spot beckoning to linger longer than originally planned - but the on-board batteries have almost completely run down. Unfortunately, the most scenic locations are not connected to the power grid. This is where the SFC A50 comes in, representing an attractive alternative to conventional power supply systems.
Reliable power supply throughout the entire winter season

Even if solar cells fail to do the trick in the dark winter season, you can count on the SFC A50 to provide adequate power. The fuel cell is capable of feeding a daily 100 Ah to the battery and delivers an output of 50 watt. With only a single five-liter methanol fuel cartridge the SFC A50 will deliver electricity for a five to ten day period - depending on the season and personal consumption. In this way, RVs can operate independently - without the unpleasant exhaust and noise of a generator. Moreover, the fuel cell can be reloaded in only a few seconds.

Thanks to its own thermal discharge the capacity of the battery increases. Especially in the wintertime, this ensures a one hundred percent availability of on-board electricity. With its mobile, clean and silent power generation, the fuel cell offers a far more comfortable alternative to generators or solar cell systems.

The unit weighs around seven kilograms and is about the size of a briefcase. Thanks to the compact dimensions and light weight the unit can be easily retrofitted and integrated into vehicle interiors. Power supply is fully automatic due to the charge controller: whenever battery voltage drops below a certain level, the SFC A50 is activated and recharges the battery. A remote control unit is available as an accessory for easy operation from anywhere inside the vehicle.

Clean and silent power generation by methanol



Also available in a lightweight weatherproof box...
