    Now here is an interesting battery run with salt water and no acid, they don't tell what the pricing is though.

    salt water batteries isn't anything new, but they don't exist in the commercial market for the simple reason that they can't handle the higher loads, as explained in this video. These are fine for smaller loads at home, but that's about it. Stacking too many of those batteries will have new challenges with cabling, fuses, etc.

    Pricing here

    Interesting alternative. Their statement of 1500 cycles for a lead acid battery at 50% discharge does not cover every day discharge, which is almost a quarter of that according to my experience.
    I find that solar charging lead acid and doing a 50% discharge that next evening on a daily basis, yields about 200 cycles.

    Ouch!

    Without import freight, import duties and VAT, it would cost me R103,054.74 to replace my current 48V/225Ah AGM battery bank! Let's use their 90% DOD example, or rather let's say I can halve what I have with these batteries, then it would still cost me R51,527.37. Without freight, import duties (+10%?) and VAT (+14%). So, R64,615.32 without courier / freight! Definitely NOT cheaper than Lead Acid.
    And then support would be costly since you need to pay the freight back.
    And you need to purchase a separate DC combiner box, which could probably cost another R6K

    At R 57,060.00 I can get a Lithium Iron Yttrium Phosphate (LiFeYPo4) battery, with 7000 cycles, locally. This is from one of the more expensive distributors. It'll probably cost a bit less through my own company.
