Edit-- might be some confusion! I did not say that it was only $300 more to get the same AH. Obviously 230 AH is more than 100AH. I already have one SiO2 (expensive) so adding another to that would also be expensive to get 200 instead of the 230 for the 6s there now. (but hard to get at--unsat) It is just that if I left the 6s in the TC I would need to get two for the MH to get back to having four there. Clear as mud?

Not clear what Azimuth is doing for price just now. I think the prices are coming down somewhat. They still have a bunch on the shelf they just got in that are not exactly flying of the shelf. I found that if you get hold of them and do your best bazaar routine, you might get a deal.
I would not buy them at all unless you had a special need that only they can fill compared with ordinary AGMs. I hope I have made that clear in this thread--not suggesting they are better in every case. In fact IMO, probably few cases. But when needs must--yes.
My special case was I needed to run the microwave at fairly high amps wrt to the battery bank AH, and the batteries were hard to get at. So Wets are no good being hard to get at, and I had no luck before with AGMs doing that work, where they apparently warped their plates the way I was doing it, and want to keep doing that. (I have no trouble in the C doing that with four 6s, but can't do that in the TC with limited vented space for batts you can get at)
Ta Da! The SiO2 is the right answer for the TC. But not enough AH for the other loads to last a few days as with regular camping work. No problem as DW was only going to be day-running or maybe one overnight at the dog training place. Then of course-- she moved the goal posts and wants to be able to stay longer, but still use the TC instead of the C because of parking space. Well drat! So out comes the Visa card for another SiO2 to make up the AH and still be ok where it is hard to get at. At least that puts all four 6s back in the C where they belong. Oh well. :)
Just how it is in the big city! :)
