i have just been browsing through an can't really be sure what has been concluded here but some ref here from someone that uses battery's to a greater extent then normal

the 1320mAh battery can in no way supply over 24W they are not built for high power delivery but high capacity and the 24W is based on 5C which they cannot deliver anyway, the circuit can defiantly not deliver much more the 5-10W

On the charge cycles, well you will already feel a slight drop (very low tho) from 5 cycle, and after 300 cycles it will have lost some % capacity, and here it really depends on the quality of the battery.

I have not been nice to my EV Ciao battery through the last year an it has lost a little over 20%, next time (in the near future) im getting LiFe instead.
