Lead Acid Battery - 2 Cells No Float

With solar you do shallow cycles and don't get PCL you would notice getting to full or near full so often. 6s get PCL too. It is easier to "recover" them after than the marine/Rvs. T-1275s are like 6s for that--loved my T-1275s!

Guys on here can help with how to attach to your fibreglass roof. You can just lay them out lashed to the cargo rails to keep them out of reach, drop the wires down to the controller near the batts.

The 1093DBD is good for marine/rv batts. Mex got me onto that and time2roll (used to be smk) was right that they like "low and slow".

Set it to 4 amps and push the Equalize button and it brings them up slowly to 15.7v. You don't have to be there for that so good for overnight. Mex wants 16v if you can get it. Anyway that gets the SG up into the green and you can do it again if the SG is not all the way up. Painless compared with the agonies I had with my 27s back when.

You want a good size bank to run the inverter doing a microwave. After you win the Lotto, you can join the Lithium stampede and get more usable AH in the same space, plus they handle big draws like inverter-MW, and no sulphation so no PCL. Meanwhile you can stall like you said with three 12s until you can tell where you want to go with your batts.

1. Yeah, I was thinking with solar, the generator and the 1093DBD, I could actually have a chance of topping them (equalizing) a few times during a week. So the GCs should start bubbling earlier, thus shortening the process. Same as at home, yes.

And loved your T-1275s, eh? Well now you've piqued my interest. A new pair of GC2s and a single, new 29 hybrid will run about $300 and offer about 310 Ah. Meanwhile, for double the money, 3-T-1275s will offer 480 Ah. wa8yxm mentioned rapid aging. Well... for just another 90 bucks for the Everstart 29, I can afford to rapidly age the heck out of those 3 hybrids and then plunk down the 6 bills for the 3 Trojans... and have a bank stronger than 4 GC2s. That's if my tray can handle almost the 250 lbs. And If I can lift 'em up in there!

2. No cargo rails. Tons of basement storage, though

3. Well with voltage regulation, the 1093 can be low and slow no matter the setting. But yeah... the equalizing function will only allow a max of 4A. But I thought the unit had to read "Full" by regular charging first, no?

4. My Harbor Freight beast, the one Mex also loves, can easily bring them to 16V. I believe it was mena who measured that unit as almost 20A on the 10A setting. The "Start" switch effectively overrides the auto function and makes it manual in whatever current setting it's on. I had run the 1093 on equalizing mode and took SG readings afterward. Then I hit the 2 good ones with the HF unit and got an average of another 0.150 out of them. So basically from an average of 1.260... to an average of about 1.275.

5. You bring up another good point. Hybrids should provide more power to the hair dryer or microwave before tapping out. I feel like we had this very conversation about your rig way back when. And didn't someone insist on an electric popcorn popper??? Or was that just microwave popcorn we were talking about?

Should there be any concern of harming the Xantrex if I'm running the 1093 concurrently? They don't give those things away, I see.
