No. The only issue is that the charge current will be higher if you tell the charger it's a 1800mah when it's really a 1500mah (if that's what it really is). It would charge at 1.2C relative to the battery's true capacity instead of the typical 1C. For a 25C lipo that's not a big deal. The charger will still stop when it reaches 4.2V/cell regardless of the capacity.
