Pipeous, does that 2400mah pack get warm? I ask as because it is meant to be a receiver pack only, the discharge rate isn't exactly great. 12 amps would make me think twice about running it in my MLST.
the 2400 mah works good in the 18B/R/T... the 1800 is a better choice for the mlst. I didn't find any problem with the low c rating for the 18B because it weighs nothing.
even on road you get dirt in the spur. I have an 18R as well
