This isn't quite right. Just having different sized batteries connected will not cause one to drain the other. Now if one of those batteries is really old/weak, regardless of size, it may bring the resting voltage of the newer/stronger battery down to its level. Also, having mixed chemistry batteries connected can have a similar effect. Meaning, if you had a flooded lead battery and an agm battery connected it wouldn't be ideal. I've personally done that one for a short period of time(less than a year) and noticed no major ill effects, though the agm would rest at the same lower voltage of the flooded battery when connected. After disconnecting the two, the agm bounced back to where it was before. Keep power and ground runs to the amps short as possible and make sure both connections are solid.

That one is not being made at this time, sorry.

Your disappointed comment made my heart sink.

As with anything it depends on your goals. I have 3 pieces of crap in my boat, does more than I need. Conveniently marine stores and craptons of websites have battery tie downs as well. Sealed batteries don't require a case, but my non-sealed ones do. Got the battery case from the same place

Just doing some calculating and have pedaled at least 100mi with my 7 yr old thia month

Werd, I understand it's photo's of someones special moment, so I wouldn't want to intrude on that. I understand changing color but I think it's stupid to physically edit people. However, photoshopping out something obscene in the background makes sense to me.

Just to be certain, can you link me to the enclosure you are referring to?

Double post.

You mentioned XS batteries in your post, which tells me you know something about this topic. My suggestion would be to contact them and discuss this to get an idea that will work for your application.

that's a dark oak stain I like working with birch but I'm not cutting another sheet until I have 60 tooth blades on my saws the shit splinters a bit with 32 teeth unless you cut REALLY SLOW.........................

Yes you need the same size battery's or the weaker one will drain the stronger battery. And I always hook up my amps to the battery in the trunk that way you have shorter runs of wire for maximum power. And you always want to have it secured or other wise it could make contact with some metal and catch fire. Myself I ran one hot wire from my front battery to the rear and grounded my 2nd battery in the trunk with the same grounding point as my amp. But I also ran 2 grounds for my amp as JL recommended. Now my 2 battery's aren't identical but they are they are very similar in size and I haven't had the first problem. You also want to fuse both ends of your hot wire and also have a fuse between your rear battery and your amp other wise you could short out and have a real problem on your hand.
