I replaced my ageing AGM's with three of their 24V 100A integrated cells+BMS packages (P24100?) about 12 months ago, they run my off-grid house and all utilities such as pumps, waste water treatment plant etc. They have been totally reliable.
The staff answer the phone and you can talk to them. They also are based in Browns Plains, Brisbane, so you can even go and see them! Free delivery too.
They have a bunch of 12V LiFePO4 products, the P12100/ss12100 may suit your needs, dunno what capacity/price point you're aiming for. I'd strongly recommend them.
