Cell Chemistry
LFP

Cycle Life
80%+ capacity after 3000 cycles

App Control
Wi-Fi, Bluetooth

Discharge Temperature
14 F to 113 F/-10 C to 45 C

Charge Temperature
32 F to 113 F/0 C to 45 C

Optimal Operating Temperature
68 F to 86 F/20 C to 30 C

Storage Temperature
14 F to 113 F (68 F to 86 F is best)/-10 C to 45 C (20 C to 30 C is best)

Using RIVER 2 Max six times a week, 3000 full 100% cycles will last 9.6 years until it drops to 80%.
BMS includes over-voltage, overloading, over-temperature, short circuit, low-temperature, low voltage, and overcurrent.
When charging and discharging at high wattage, RIVER 2 Max may make a noise up to 62db.

UPDATE 

EcoFlow has reached out to me regarding the battery health and fast charge of the unit. The company claims charging the unit at the max rate doesn't affect the battery health. They state:

The fast charge function doesn't affect battery life. 
The charge rate is set according to the AH capacity of the cells. The higher the AH of battery cells, the higher the charge rate.
The new RIVER 2 series and DELTA 2 series use higher AH cells (20Ah). The C-rating (charge rate) is relatively high, which means that the battery cells can take up to 20A and can therefore be charged faster than before.
While I appreciate the feedback, I would still prefer to stick to the 200W charge for ease of mind. Heat build-up isn't good for batteries and higher, faster charging causes heat. So I would sleep better at night knowing the unit isn't getting too hot.
