Using mainly EGO Chainsaw, does the 7.5 Ah battery put out more power (better performance) than the 5.0 Ah battery, or does the 7.5 Ah battery just give a longer run-time than the 5.0?  Thanks

John, EGO makes two chainsaws (14" = CS1403 and 16" = CS1604).  The 14" comes with a 2.5 Ah battery, while the 16" comes with a 5.0 Ah battery.  Additionally, the 16" chainsaw has a "slightly" higher Watt motor versus the 14" chainsaw.  Now, the 7.5 Ah technically speaking has 3x more power than the 2.5 Ah battery.

Power (Watts) = Volts x Current (Amps)
  • 56V x 2.5Ah = 140 Watts / hour
  • 56V x 5.0Ah = 280 Watts / hour
  • 56V x 7.5Ah = 420 Watts / hour
To that point; I am not certain if the chainsaw will (and/or) can use all that power.  What is certain is the 5.0Ah battery will last longer than the 2.5Ah battery.  Several owners on this community board claimed that the EGO chainsaw does detect the size of the battery, and therefore, can support more power to the motor - which gives you more cutting torque at the blade.  The only way to know for certain is to contact Customer Service to validate this.
