Extensive testing has been performed with
EVE EF651625 750mAh cells which have shown very poor performance - 8600 LR1110 GPS positions + LoRaWAN messages (6 days sending a position every minute)
Saft LS14250 1200mAh - 72000 LR1110 GPS positions + LoRaWAN messages (70 days sending a position every minute) Expected difference in capacity at this load profile is 2x, but the performance is 10x difference
