No he is right. We should launch and 20-30 minutes later have a trophy fish of our choosing. Back at the house before the warden wakes up

Bypassed the switch, installed new cartridge, soldered and shrink wrapped up new terminals, did the same to the new 6 volt battery. And what do you know....it pumps like a champ.

It's not Bob, it's Tom. I live in Bakersfield, take my Mini X out of Shell Beach
(part of Pismo Beach) for only a couple hours, two fish and I have dinner. I absolutely envy you guys down south that get to fish all year. I won't get to fish from my kayak until May 1, 2015. Love your forum, please excuse my interuption |

X2 it's takes me 6 hours to make bait ......but side note I was having the same issues less splices the better I hard wired mine w/o switch Beside how often do u need to turn the dam thing off. My battery would be fine at home on voltage and power on the pump . But when the splices got wet after being on the water a couple hours I would lose voltage just do to water getting in the splice heat shrink splices

Battery (I know this is old)
So here's my $.02 on this. I poise a question. Why would Hobie use a 500 gph bait pump designed to run with 12 VDC, and run it off of a 6 volt battery? I already know the answer, and I'm not really asking the question. By running the pump with 6 VDC, it restricts the water flow. It's an alternative to running the pump the way it was designed and using a ball valve to restrict the flow. Now using an electrical component under it's suggested voltage rating won't hurt it. If you were pushing more than 12 VDC (say 14-16 VDC) you would fry it. Also, an electrical component is only going to pull the amperage it needs. That's why you can hook the same bait pump up to a deep cycle SLA cranking battery on a boat, and it still works without frying.
I my opinion, this is lame! The battery compartment on the bait tank is designed around the dimensions of the inadequate battery. The overboard discharge tube in the bait tank is adjustable to accommodate variables in water flow. It could easily keep up with the 12 volt battery running the pump at full bore. I've searched high and low for a 12 volt battery with the same dimensions and amp hours, but to no avail. But then again, the battery compartment isn't water tight anyways. If you roll your kayak, it's going to get wet (even with the designed configuration from Hobie). If you wanted to use a larger 12 volt battery, then remove the protective cover from the bait tank, and strap it straight down. You're out there to fish- not win a fashion show. Who cares if it doesn't look as aesthetically pleasing as the designed configuration. As far as waterproofing splice connections- if the marine grade butt splices are utilized properly; not only are they impervious to water penetration, they will last forever. The key is what you use to shrink them down. NEVER, EVER, EVER use a lighter or a butane torch. They get too hot, too fast. And they heat the splice unevenly. They also have a tendency to scorch and ruin the material. ALWAYS use a heat gun. Harbor Freight sells a heat gun that is AWESOME! http://www.harborfreight.com/1500-wa...160-69343.html This heat gun has 12 different settings so you can heat shrink the small delicate stuff all the way up to the high voltage electrical heat shrink. If using the marine grade heat shrink butt splices, heat them until you see the inside of the butt splice start to liquefy and adhere to wire. Make sure your stripped wire end is long enough to bottom out to the center of the butt splice, but short enough that there's not a shiner hanging out of the butt splice. It's VERY easy to find the proper length. Tightly trist the stranded wire together before crimping. And use a proper crimping tool. Make sure it's designed to be used with insulated cripms. If you perforate the shrink material on the butt splice, you've defeated the whole purpose of what you're doing. ESPECIALLY inside of the bait tank. You have salt water sloshing around the whole time, and when you mix salt water with DC current, it creates massive electrolysis on the wire. This accelerated corrosion. Copper corrodes at a molecular level. That's why when your components stop working, and you strip back the wire, you see that red dust come off of the copper wire. That's the copper equivalent of rust. Just replace the whole length of wire at that point. As far as you start to trim it back, you're going to find that red crap inside. Anyways, enough of my rant about that. The point I'm trying to make is Hobie is lame for designing the bait tank around a 6 VDC battery and using a 12 VDC bait pump. Like I said, just my $.02 though. |

The 500GPH pump running on 12 volt would be great if your tank was 15-20 gallons, not sure why you think the tank needs more flow, also I'd recommend using marine grade stainless wire, not copper. What exactly do you find to be "lame"? The run time? the amount of water flowing?

That pump running on 12 vdc KILLS our BAIT. Running on 6 vdc the bait is fine and the pump lasts twice as long.

7.0 Volts for the old battery that only lasts 5 hours 7.0 volts for the charger 6.8 volts for the newer battery that lasts all day Conclusion - just because a battery will charge to a higher voltage does not mean it will last longer. The older battery must have some kind of memory damage, thus it discharges faster. |

Hobie Bait Tank 6Volt Battery Question
12 volt battery will cause too much flow. Tried it. Drain cant keep up. Fomen, not sure why you think the 6v battery is incapable. Ive had my original battery for years and still running like day one. I keep everything alive from pinhead chovies to giant macs, and I overstuff with bait. Im talking 10 hour days! The only baits ive EVER had roll on me were macs that deep throated my sabiki. I would say you are doing something wrong if your hobie bait tank is not working right. Soldering connections with marine grade shrink tubing is superior to your butt connectors. Another thing I suggest is eliminating your switch from the tank. Seemed like I had better flow after wiring straight to the waterproof battery connector. And lastly, charge and discharge your battery properly. I can fish two, ten hour days back to back on one charge with my tank and "incapable" hobie battery with no problems, I would look elsewhere...

Are the different batteries you are speaking of rated for different amp hours?? Might take a look. |

Ask Dr Science, He knows more than you do ... :-)
Here is a little history on a rather elegant and somewhat serendipitous engineering solution.
Before "fishing kayaks", off the shelf bling, slap down a credit card and go fishing, it was roll your own. So we would get a bilge pump, connect it to a cooler or vittles bin, hook up a 12 V battery and go fishing. After all, the pump was "rated" at 12 V. But the battery didn't last too long and the pump flow beat up the bait. So some of us tried a resistor to knock down the flow and increase battery life and it worked but not too efficient. Then some of us built PWMs that really controlled the flow and increased the battery life. On/off timer switches did more or less the same thing. Then someone came up with the bright idea to try a 6 volt battery. Lo and behold, the bait tank flow was good, the battery life was greater than 2x the 12V and no electronics to mess up. A rather simple and elegant engineering solution which I would not characterize as lame. Hobie didn't come up with this but I'm sure they saw what was posted here and on other boards on 6V batteries and decided to go that route. I run a 6V battery on my Hobie tank is it works just as well and just as long as my 12V PWM bait tank with less chance of failure. |

They are both 6v, 10ah batteries with all other specs identical. Both purchased from Hobie for use in their live wells. The only difference is the manufacturers....Newer made by DiaMec, the older labeled Master brand.

I see the problem right there, you can't use the Masterbait battery, that will never last too long without going limp. Unless your 16 and then it will at least recharge faster. |

I had that same issue a few years ago. At first I thought it was the battery so I ordered a new one on Ebay, as soon as I received it I gave it a full charge. Because we were headed to Erendira that same week I wanted to check the battery life before our journey and needless to say the battery last all but 3-4hrs. I thought that perhaps I received a battery that had been sitting around on a shelf for a few years so I decided to head over to OEX and picked one up from Andy. When I got home I charged the battery and once it was fully charged I installed it on the bait tank and let it run. Well, guess that happened....the battery only lasted 3-4 hrs.
After talking to Tony and mentioning that my pump was a little louder than normal he suggested that I replace the the bait pump. WHAT?!! He's crazy, it can't be the pump! Ebay and OEX sold me old batteries.............at least that's what I thought. I had to make a trip to Westmarine so while I was there I went ahead and purchased a new pump. As soon as I got home I Mickey Moused it, connected a fully charged battery and WALLLLLA!!! The motor/battery were still running 8hrs later.
