New Battery Manufacturer 'Lifos' ...anyone used?

Hi Guys,

These look pretty decent. Is there anything obvious I've missed?

Cheers

Lifos Advanced Lithium Power

Lifos uses the new premium in leisure battery chemistries - Lithium Iron Phosphate (LiFePO4) - to deliver safe and reliable power for a wide range of uses. It is perfect for charge sensitive, high cycling applications including leisure, commercial and off-grid energy devices.

Some considerations:

1. 123Wh/kg energy density, which is 102.5% of the theoretical maximum for the chemistry. Bold claim.
2. First BMS I've seen that support 4 batteries in series
3. Coulombic efficiency should be around 98% for LiFePO4, they say ">90%" in the datasheet, which arguably could include that!
4. No low temperature cut-off

Looks like a nice product. Bit wary of 'new products', though (...I know, bit risk averse mentality). Would I buy one, yeah, probably, price dependent, obviously.
