My removable Battery Bank!

[bigcitypopo]

Soooo,

I recently installed a 75amp boon docker upgrade converter in my springdale. Its great!!! I had two grp 24 batts from my aljo that i have kept watered and charged...

So, i rigged them up in a removable type tote with a quick connect battery cable.... Pics below

Here is the Tool box!



Drain hole and vent holes drilled... 8 vent holes... and 4 drain holes



cable port...



Group24 box...



With handles cut off.. all but one to allow some spacing...

boxes installed in the tool box, wired up....



6gauge cable with quick connects soldered and heat shrink wrap...



installed on the cable pair on the trailer battery bank...



Connected up...



Stowed... the box weighs 85lbs... Handle easily supports it. The latches are locked with a padlock. Im not to worried about someone running off with it. they'll have to crawl under the rig, cut the huge hardened cable... Drag the sumbeach... and be quick enough to run from my shotgun.. lol

Interesting idea, but IMO I sure wouldn't consider something with a handle like a tool box weighing way north of 100lbs as being portable. I know my 50lb Honda EU2000i is about the limit of what I would consider portable for something with a handle.

I started out with four each 85AH standard issue Interstate 12VDC batteries and lost one due to boiling out fluids with my single mode Elixir Converter/charger unit.

Been living off of the remaining three Interstates (255Ahs) for the past few years with smart mode converter/charger and works out great for our lifestyle. We end up at around 12.1-12.0VDC each morning at the battery bank.

Then we run the Generator when allowed and recharge the batteries back up to their 90% charge state in around three hours generator run time...

My future plans are to add 300AHs worth of batteries to the trailer and also in the back of the truck to run all of my toys when running my truck stand alone with my emergency radio nets or combined with the trailer when camping...

The plan is to use the Trojan T-1275 150Ah 12VDC batteries but cost will probably drop me back to using the Golf Cart 6VDC 225Ah Battery sets in both locations. My 2008 Installed Interstates are now starting to lose performance...

Supplement this with solar panels should keep me in the pink for years to come...

Question though Dave, why do you need 4 batteries? Isn't the camping family a bit smaller now with your daughter off to college? With fewer people I find we're in the trailer less and with fewer kids there's less use of the electronic stuff like movies and games.

I really like this idea of a portable battery pack. Thanks for the insight...

Perfect !

Any thought about venting at the very top of box? I've read hydrogen is 20x lighter than air. Wouldnt want a pocket of it next to a quick disconnect? Not a battery pro, just thought I'd ask. Looks great and extra battery cap is always good !

I could be off on the weight... I lifted it it no sweat... But. I really wasn't estimating well. Nonetheless, the handle and the side handles are super stout.

I'm looking at the go power flex panels... The seem super tough...

[bigcitypopo]

I ordered a couple of other of the quick connectors... I'm gonna rig my moms Class C with a "bank" connector and a dedicated charge circuit at home... It's kind of cool to be plug and play...

I'm hoping to be able to upgrade to 6v when these batts die... It's cool to have some relatively portable power.

Nice job and nice post! Thank you. 🙂

Great idea with the tool box battery case...

I have been doing something similar with a couple of GP24 battery boxes mounted on a small one inch panel in the back of the truck bed. I have a long 4AWG two conductor cable that will plug into my off-road POPUP trailer. This all temp for now but will eventually wire all of this into the truck permanent.

This supports my Ham Radio ops for the truck when by itself and will also add to my POPUP trailer when in camping mod.

Adding battery bank to the truck bed was big brain storm since my 2KW Generator is already sitting there. Takes weight off my trailer tongue area and keeps my Camping and Ham Radio hobbies going...

My ultimate plan was to install two TROJAN T1275 150AH batteries in both locations... That would give a big 600AH battery bank when in camping mode.
I am currently running two groups of 12VDC 85AH Interstate batteries giving me over 300AHs of usable batteries.

Nice mod. I've always wondered about doing a "portable" battery bank like that but had not seen it done. Great idea.

Two of my East Penn gel group 24s would weigh 150 pounds. Those interstates are some light batteries. Nice workmanship though.
