Would it make sense to replace my four 6-Volt batteries with 3 Li, assuming boondocking would become my primary activity? Two would seem sufficient for routine camping needs, but if I'm off-grid, I like to have plenty of back up, should it be needed...


Hmmm.... I think I figured out the answer...

First, the dilemma, then the answer... My dilemma came about regarding dimensions.

Initially, it appeared I would have trouble fitting them in, because the dimensions of the Li were larger than the battery tray - too long by about 3". Even with the 100Ah, I could only get 3 in, length-wise front-to-back, to replace my 4 flooded jars. That meant removing the tray, having it modified to fit the new Li's. Then I remembered something... these Li's can pretty much be positioned any way one chooses, absent upside down, so I measured the battery compartment, and discovered I have about 20 1/2 inches of height open to me, and at 19.1/16", standing both of the 200Ah I wanted on end, wired in parallel, they would fit just fine, as long as they were strapped down and secured to the tray... I would then have 400Ah at the core of the system.

Does anyone see an issue with this approach?

“ Does anyone see an issue with this approach?“

YES, you’ll be starving-out the good guys at PG&E - lol !!.... Not a problem so long as your battery manufacturer’s specs allow for parallel connection...Might be a good time to consider an upgrade of your cables as well...

I gave the Chinese mfrs of my lithiums the size dimensions of my small battery box, 14"x8"x9.5", & they custom made 2 100AH batteries for it.

I ended up dealing direct with them and paying through Alibaba;

After having my service guy look things over, he came up with the idea that the sliding tray the batteries were on was taking up a lot of space, and that by removing it, I could not only fit the batteries I wanted in the now empty space, I could probably get 10 flooded batteries in there... a terrible waste of space, he said... but, it appears the best choice for me are the Battle Born Lithiums, and have decided to go with 4-100Ah that should fit nicely, with the tray removed...
