​Why 80Ah? 

As lithium cells become larger, their cycle life decreases, 80Ah is a good balance between practicality and lifespan.

No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.

4.2.4

Absolute Charging Voltage

Maximum 3.8V

No matter what the charging model is, including pulse charging, once the voltage of the cell is above the absolute charging voltage, charging should be stopped.

No matter what the discharging model is, once the temperature of the cell is above the absolute discharging temperature, discharging should be stopped.

 
With the repeated charging and discharging, the battery's capacity will gradually decline. The number of charge-discharge cycles a battery can go through before it reaches 80% of its rated capacity called cycle life.
 
For full specifications, please see the manual attached - below the main product photo.

5-YEARS after-sales guarantee. If there is a serious non-compliance with the technical standards of A-grade cells not meeting the following:

  • the cell capacity must meet or exceed 80ah 
  • capacity tolerance within 1.5 Ah
  • voltage tolerance within 5 mV 
  • resisitance tolerance less than 0.2 milliohm

Note: A BMS with cell balancing and overvoltage/undervoltage logging is required to prove suitable usage of the cells.  Please see the Daly BMS or REC BMS units.
