Eagle Cap 850 Battery Compartment

Well, the 6V Fullriver batteries arrived. It was a tight fit...but this will give us 250 A/H of true deep cycle capacity.

Specs;


Tight fit through the door. Height was the real challenge, only about 1/2 " at the door. A couple of inches taller once they are in;


With both batteries in, there is about "1 hand" left on depth of battery compartment. I put a wooden block in so batteries won't move around;


We don't use a lot of power so this should get us through 3-4 days easy. The only time we use more is ski camping, we will carry the H2K then.

Thanks Bob...the Eagle Cap has a pretty good sized battery compartment. Just to be sure I made some cardboard mark-ups to verify fit.

Kind of funny...I never heard of the Fullriver brand until recently. Apparently a top of the line deep cycle battery...

Bill, FR is a good choice .
I remember reading some solar info on 6 v. batteries. If my memory serves me correctly .....

verify the following if you need more room .
if you are short on room in the battery compartment and you need a little more wiggle room to make the connections, look into using a copper buss bar . I think it offers better equalization between the 2 batts as well as being able to use a thinner wire that will bend easier in a tight compartment.

Looks like I will go with 2 Fullriver DC250-6 6V AGM's. If I purchase through my office via local distributor there is a significant savings vs retail so I am going with the largest 6v I can fit. Note; if you have access to a commercial account I was able to save ~ > $60/battery!

These will give us 250 amp/hr- 25% more than current GR 27's and the cycling ability of the 6v should reap benefits over time. In speaking with the distributor (who knows more about batteries than I ever will!) he did not hesitate to reccommend the FR brand when I asked which deep cycle battery he would reccommend for RV's. Interesting as they carry MANY different brands.

I am seriously leaning toward 2 x 6v. They are 10.25" lg x 7.06" wd x 10.19" ht.

Plenty of lg and wd...ht will be tight; 11" at the door.
Hope I can get my hands in to bolt the straps on!

Thx, Bill

Without grounding the tool in the process. I've done a little arc welding with my 27's.

series = volts double , I think amps remain the same.

if you then add two more 6 volts to that pack, you would be able to double the amps.

caught me on that one Bob!

Yes you are correct...

Went out and measured the battery compartment last night.

The 31's are .86" ea longer than the 27 12.91" vs 12.05".
I have 1 battery out right now (in the airstream) and with 1 in there I still have a solid 15" to the door. that mean a good 28" OAL.

2 GR 30= 25.82".

2 gr 27= 24.10"

SHOULD be fine. In fact I use a 1" block of wood with my 2 gr 27 to prevent them from sliding around.
I know it will be tight, but being AGM's...once they're in, they're in for good.

I want to get 2 more batteries so I can stop switching back/forth TC to AS...a real PIA! I will put new batteries in the TC.

I think it's time to give Randy a call...
