Got interested seeing the headlines. Trying to see the merits.

I could find two contenders for these batteries.
1. Zinc-bromine flow batteries from ASX:RFX.
I believe these are priced around same as SAS batteries. Fire proof and lithium free. Manufactured in Thailand. Company have struggled for years to generate sustainable revenue.

2. LiFePO4 battery.
Wikipedia says-"Because of its lower cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility scale stationary applications, and backup power. LFP batteries are cobalt-free. As of Q1 2021, LFP type battery market share reached 24.1%, with Chinese manufacturers holding a near monopoly ..."

As found on eBay today-
BYD B-Box Premium LVL 15.4kWh Battery, Brand new, AU$12,120. (supposed to be LiFePO4 battery)
Green Bank LiFePO4 10 KWH lithium battery 48V 200AH 6000 cycles 5Y warranty, Brand new AU$4,760 +AU $385 postage
[At today's rate, those prices are BYD: EUR8,100 and GreenBank: EUR3,200 + EUR260].

Will appreciate if others can correct or add to these info, so people like me can make-up our mind.
Cheers.
