I have fished on a boat that has had all 3. [electramate, daiwa, krystal]
By far my Daiwa 1000 is the Cats A$$ compared to the others. That's not just me saying that. It's the othere gys.
But I don't plug mine into the boat as I have it totally self contained. No I don't use the $400 8ah battery pack that Daiwa sells. To big and to bulky.
I do have a custom 8ah battery that straps right to the rod. No cables to get wound up in and I can take it on any boat.
Mine is the Proto type. I can run the reel for 2 days fishing on one charge.
Contact me if you would be interested in one of these battery setups. The connector and wiring is 10ga wire with a 2pin flat plug.
This setup still weighs less than a Electramate. The Daiwa 1000 will dead lift 25lbs. 30lbs will pop the internal CB.
I know that doesn't seem like much at first, but this is off the side of the boat on the ground. Not in the water where buoyancy comes into effect.
