Battery Storage

[Two Showers]

I tow with a VW 1641cc TRIKE. So we have weight issues and everything has to be kept as light as possible.
My problem is I need to store a leisure battery in the mini caravan, just for 12v lighting and phone charging, iPod stuff etc
I need to find the smallest battery I can as space and weight is an issue.
If I use a leisure battery do I need to ensure it's in a sealed container with ventillation to the outside?
Is there a dry cell 12v battery I could use, as I have space to store inside the caravan but sealing to vent externally is going to be a problem


This was my first Sleeper, which is basically a bed inside a fibreglass shell

Now I've (with help) developed a 'dropped' box trailer to reduce the size and weight (for Trikes) but gives storage, somewhere to sit and a double bed. Easy access for wheelchair users, and it's just waiting for the full double glazed caravan windows to go in and the wiring to be finished when I get a resolution to the battery issue.

Have you looked into solar? I don't know anything about it, but a panel would have to weigh less than a battery...

Sealing an inside battery box that vents to the outside is easy. Just use caulking on the box and foam weather stripping to seal the access lid. Get a little aluminum, circular vent from the hardware store for the outside.

A solar (photovoltaic) panel won't give you electricity at night when it's needed for lighting.

That's fine if you're talking about a Tear that's large in size, being pulled by a car/van/truck, but my Teardrop is a modified small (very small) box trailer that's been dropped in height. Deliberately made for towing with Trikes or very light kit cars or micro cars. The seat/storage you can see is only as tall as a battery, so I can't fit it under there.
I'm trying to find a way of fitting or identify a very very small leisure battery which would go under and allow me to vent outside, or a dry cell battery that doesn't need venting. It's hard to tell how big my micro caravan is, but trust me. It jsut makes a bed 4 feet wide by 6'6" long.

Motorcycle batteries. Lawn mower starting batteries. Or if you want the exotic, explore www.batteries.com

...and check out MARINE batteries, like this example:

Happy hunting,

I would grab an AGM motorcycle battery. Small, light, and no fumes, or so they say. If all you need it for is lights, it should last all weekend without a problem.

It probably wasn't necessary, but I put a hole in the floor and in the sidewall, just in case.

TS, I am presently using 2, 6v, 33ah SealedLeadAcid batteries, which are designed for a backup power supply...they are 2.75"s thick and about 6"s square, giving a footprint of about a 6" cube...I paid 25USD each at www.batterymart.com ...I'm sure something similar is available on your side of the pond...........

Cheers Guys, I much appreciate the info

[Two Showers]

Thanks for all the help.
I'm now running a 17AH 12V (Golf Cart Battery) as I've found it can be put in any position and as the Teardrop only has LED lighting, it lasts for days and days. I then take it out to charge it. I don't need to charge whilst riding the Trike so its saved me a lot of wiring.
I appreciate all the guidance you lot gave.

What about one of those power paks that jump car batteries? I use one in the VW for (110v)lights. Can use a cig lighter adapter for 12v. Does have a low noise when on, but I don't have it in a cabinet.

Its all down to weight. With a 550Kg Trike, I'm limited to towing 250Kg

SO for Tirkes in the UK we have to go ultralight.

It depends the quality and size. φωτοβολταϊκό πάνελ or photovoltaic panels and good batteries can give you more power to charge you phone, stoves and lights..

I'm curious about this idea, can you tell me more about the battery pack you use? Why does it make a noise? Do you recharge it in your VW while underway? How long does a charge last to power your trailer, and what do you run off of it? Any problems with battery life given multiple charge/discharge cycles?

Thanks!
