A rigid plastic case to store safely your AW IMR High Drain 18650 batteries while you are on the go. A virtual necessity to prevent shorting-out if you are carrying batteries separately in your pocket or bag.
Now I know why they have made the bottom coil tube tank the size it is ,
you can dual use their batterie case for batteries and bct's .
The new bct's are an exact size match to the LAVACELL battery so a few cases is all you need to keep everthing safe and sound , no more batteries blowing up in a pocket full of coins no more leaky tanks due to the bct being a threaded bottom tank and stored in a sturdy case ,
all we need now is a nice transport box to place a good size collection of battery cases and accessories in for when we are away from home or even for storage when we are at home ?
