white paper on SiO2 batteries
Hi, Finally found one. It compares Lead Acid, Nickel Based, Lead Crystal and Lithium Based Batteries chemistries. https://azimuthsolar.ca/wp-content/uploads/2020/08/study-of-comparison-of-charac...
Forum Discussion
Not clear on how much they tested the SiO2 themselves or used reported data from somewhere else.
Interesting that they say to charge FLAs at least at 10% charging rate, but no more than about 25%. I have found that rv/marine 12s like low and slow under 10% as long as you keep doing that till they get to 16v. Otherwise it is a real chore trying to get them to full SG.
I have not been able to really use my two SiO2s in the camper since last December due to Covid, so they have just been floating except for a deep cycle test in July to make sure they were ok. They were.
I think I will move them to the MH to get a 6 batt bank for the winter and just go with a single 12 in the camper for the day-running it only does these days.
I agree with PT to wait till next year when you will have a chance to use them before spending the big bucks.
I see Azimuth still has 36 of the ones he got 50 of before Xmas, but he has jacked up the "sale" price some lately. Don't understand that! Shelf life is happening big time there! Would have thought the price would drop by now.
