Interesting article! He uses time before a needed recharge as "usable AH" for his comparison (relates to the other thread on that) where in each case he has four 6s.
In my scenario I would not get the long lifetime many cycles advantage so that money would be wasted, but I would get vs AGM:
- the very little sulphation
- the high draw on one battery
- leave it undercharged long times no damage
-no need for an ammeter/Trimetric for proper recharging
No access location is the same for SiO2 and AGM so that is a wash, both vs can't do that with Flooded.
The scenario I have means it can be done with two AGMs or one SiO2 for the same money, so that is a wash ( I don't need the more "usable AH" per battery to stay out longer)-or I can save money by using Flooded and do a bunch more inconvenient work to keep it all going.
(I went back to Flooded for the MH because I can get at them easily to see water level and all that. Not a convenience problem, no need for sealed batts of any kind there.)
That leaves the SiO2 advantage of little sulphation, leave undercharged, no Trimetric.
I had a similar scenario and used AGMs. Ended up with warped plates from high draws (most likely what happened, Mex says) despite looking after them properly using ammeter and all that.
I don't need an SiO2, but it would be a treat to have one. (Don't need two) so it is all about convenience "worth" vs state of the piggy bank :)
