I wouldn't use a lower resistance carto on those
batteries because it could be dangerous. If you want to run LR cartos you should have a battery of 450 mah of higher because the LR carto will try to draw more current then that battery will allow. It will drain your battery faster like
jtracc stated but will also diminish the life span of the battery as well as possibly cause the battery to fail. Presumably there are safety features in the battery to prevent failure but what if that were to not work as designed? To me, not worth the risk!!! A lot easier to by a bigger battery to run LR cartos then it is to buy a new face god forbid something were to happen.
