Traditional Battery Case for 280ah Cells

[ChuckNorris]

i would also love to know the results of the 280ah cells. Did you capacity test them?

 

[LanduytG]

Here are a couple of pics with the Eve 280ah cells and BMS inside. Fit is perfect with room on the end for BMS. Just thinking how I'm going to secure them in the box. Terminals on lid are M8. Comes with handles. Will most likely use screw to secure lid.

i made it work in a grp 31 box from wally...$11.

I also bought this NOCO battery box. Costs in the Netherlands € 20. Perfect for storing 4 280A cells and a BMS. I think I will put a different lid on with the battery connectors on top.

Battery terminals are on top.

version 2 of the NOCO battery box

i moved the battery posts to the same side of the case.

i trimmed the plywood cradle to accommodate the battery posts fit in the box. i'll probably cut a piece of plywood to secure around the top edge to complete the cradle. the cells are held together with the vhb tape.

the grp 31 box is a bit big to fit back into the original location for the batteries, at least with the lid on. the height of the lid makes it an issue. im not sure if im going to change the box or change the battery location. we will see, thats for another day.

I built up this pack and dropped it into a Todd Universal Marine Battery box. It is about 1" taller, wider and longer than a group 31 battery box. Heavy duty and fairly reasonably priced. Todd Universal Battery Box

What's the dimension on the 2 big aluminum end-plates there in your pics?

 

[Opie91]

I do not have the exact height as the batteries are installed in my boat, but used this 8" wide piece of aluminum from McMaster. 3' piece was big enough for 2 packs (4 plates).

Sounds great, thanks for following up. I also found some measurements from the battery spec sheet and drawing up some plans now as well. Thanks again bro...

Looks sleek and like a typical battery, I like it, I wish it was cheaper

Greg, are there screw holes to secure the lid or do you have to fabricate the holes?
Thanks,

[LanduytG]

You have to drill the hole. I drilled and tap for #8 and used counter sunk heads.

HMMMMM,

this thread got me thinking, which is always dangerous!

Has anyone tried a small cooler as a box? I know there are lots of CAMCO battery boxes out there for cheap, but here's my thinking:

A cooler is somewhat insulated, perhaps keeping things warmer longer
The handle would be handy for toting
Way cheaper than something like a Pelican case.

Would love feedback on the idea.

What size studs did you install on the cells to still allow the top to fit on the box? My measurements show it as a pretty tight fit in there, but based on your photos it seems to work fine. I see the height of the cell as 207.5mm, and height of box as 215mm. That's only about 1/4" of room......?

The lid sets a bit higher. Used 6mm×20mm set screws with flange nuts. Plenty of room.

Thanks!

Are the external dimensions of the box listed correctly then? I see it as 245mm high? Or is that the height of the box and the lid is higher? If so, do you know that measurement?

Well if you used the coolers, you'd have a cool handle to life them up and out....

I've had that thought several times. Have you searched through any measurements?

I do recall someone using a cooler. I think the only problem is the thickness of the walls if intending to use battery posts. Of course there are several ways around that. For example one could use Anderson connectors to connect between the battery and an inverter.

I do think a cooler would be fairly sturdy. A box that won't flex on the bottom would be good to prevent stress on the cells terminals. If it flexes, throw in a 3/4 inch plywood in the bottom then you should be good to go.
