Comments on Elecyr's Smart Battery (LiFePO4)?

[grjfield]

I have a 40' sailboat which I converted to electric a while ago. I currently have 235AH of lead acid batteries and for my needs it works quite well.
My intention was always to upgrade to LiFePO4 when the price improved.

I recently came across a vendor (ELECYR) in the eastern US who carries a LiFePO4 product I'm considering. Apparently the batteries are Chinese and the US company has a proprietary BMS. They have positioned themselves as an alternative to the Tesla Powerwall.
I noted in their 'Marine' Application page that one of the owners had undertaken a conversion to a Hybrid Electric Propulsion System on his sailboat..hence my interest.

Their battery is called SmartBattery, 7.5 Kwh for ~$4900US.
The battery has a max output of 40A @ 48V, so to make it viable for my setup, I would need 3 or 4 set up in parallel to achieve 160A to get close to hull speed.

They also have a product called the Daily Sun, also 7.5 Kwh for $5900US, which has a built in 1500 inverter.

My question is...
Have any forum members come across this product/company and would care to share any insights?

I have attached the website below.
