I run my fish finder on the Milwaukee M18.
- Lighter and more compact than the Dakota.
- Designed for cold weather use.
- M18 has 12 Amp hours instead of 10 amp hours on Dakota.
Bottom Line is that 18 volts at 12 amp hours has nearly DOUBLE the watts/power (94% more) of the Dakota
Milwaukee M18 = 216 watt hours
Dakota = 120 watt hours.
And, it will also run my Milwaukee drill/auger so I have a redundant battery without actually carrying a spare.
