Evening all; i ask this as it says under battery cautions/care you should never fully discharge a battery as this leads to an unstable battery. So when do you know it is time to recharge - when power light turns yellow or red??? i am using the Efest IRM 18650 battery in the SVD. Thanks again...
Also when do you know when to charge the MVP? Is it the same as above??
