I have had Powerdrive 12 volt v2 with co pilot for a couple of months now, and been Long lining and trolling cranks about 2 months. 15 minutes into trolling crank baits, motor would spin and only way to stop it was un plug it and then plug it in and start moving again and it did it a second time freaking me out alittle as well as tangling lines up, figured it was battery getting weak so switched remotes as I had a spare, and it never did it again. Both hand helds are brand new, so just curious as to how long the batteries last as I will change them out, carry small screw driver and spare batteries with me also, I figure I have used the remote about 160 hrs or so.
