Sure, you can always upgrade to a larger battery than what your light originally came with. The runtime will be extended.
HOWEVER, we don’t recommend downsizing your battery, e.g. using the Magicshine 6500S/8000S with the MJ-6112/MJ-6116.
Operating a higher wattage light with a lower rated battery may exceed the current limits of the battery, causing overheating and trigger the protection feature to kick in.
