I think Ful-rac uses the same batteries. The batteries aren't cheap but not having to wonder when you're FF batteries will go dead is priceless. |
you never EVER want to drain lipo batteries to the bottom. That is a good way to toast you expensive batteries. That is why you install a batt monitor parallel with the circuit.

That might not work for two reasons. Most lithium rechargeable batteries today charge the individual cells in parallel. I'm guessing that's the same approach Greg's supplier is using, although I could be mistaken. Second is the charge voltage for lifepo4 is a little different than lithium ion and lipo. |
Yes, what John said. You need a special charger for LifePo4 batteries which are not the same as Lipo batteries or lead acid batteries.
|
Jorge, your charger is for 12v batteries. This thread is for 6v bait tank batteries. If you are asking if my charger for my 12v battery has the same output, I can check for you when I get home.

I think I'm interested.. but sorry if this is a dumb question. So my Lowrance FF won't run on this 6V battery? I know my livewell (Johnson 500gph 12v pump) will run on the 6V. Just wondering about the FF. It's the bigger Lowrance Elite 7 HDS. :rolleyes:
If it's all good, I'd be interested in 2 batt + 1 charger. I'm in Long Beach area, so I could probably come by to pick up. Thanks Greg.. :cheers1: |
FishNinjaY, my FF needs 12v, most do.
|
All the FFs I have owned were 12v, but would run down to about 10v before shutting off. These batteries are designed for bait tanks. At 6v, a bait pump runs at less than half the rated amps for 12v operation. That means longer run times than for a 12v battery with the same amps. They also lessen the water flow which is important with pumps putting out 350gph or more. You will not have to worry about these batteries running out of juice in a day, or even 2 in most cases. With the 4a charger, your battery will be fully charged in a few hours. Granted, I go out more than most, but I have a table full of 6v lead acid batteries that do not work any more.

Pretty awesome of you to be doing this. How much does one of those weigh?
Count me in for 2 batteries and a charger Thi |
Hey Greg,
If they are making a custom battery for you maybe you could ask them if they could make a larger capacity 12v with a six volt tap ? maybe you could avoid the second battery altogether? I use a dc-dc convertor which is not bad but I do lose some power from the convertor. Just thinking ;). Darren |
The weight of the batteries is TBD because they are going to be custom built. My 12v 12a batteries weigh 3.65lbs, so I am guessing about 2.5 for the 6 volts.
The point of these batteries is to provide a lot of power, not to consolidate. Combining them would require a battery size that I would not want to deal with. My 12v 12a batteries are as big as I would want on a kayak. |
Greg! Don't know where your count is but I'm good for a battery and a charger. Let me know. Thanks! Jim
|
Everybody that has spoken is accounted for. I only have 5 of each (batteries and chargers) unspoken for.
|
Greg,
If you do this again with a 12V battery setup count me in! I am still debating on the 6V if you have any left by the time I make up my mind...LOL You really do rock sir both for your videos which I am addicted to, and this project. Thank you kind sir! :you_rock: |
Here you go jaws. Make sure the dimensions will work for you. Comes with charger.

I'm talking to that same company about the 12V12Ah LiFePO4 battery. If we order a few, there's a small discount. You interested? I'll post up separate from GregA's post here, to avoid cluttering his group buy. Txt me if you are in? Kev, I think that *free* 12V battery you gave me crapped out too early, on my trip.. so I had very spotty fishfinder function. I need to get batteries for my multitester to check it, but I probably need to get something newer and more reliable for my FF and livewell tank. |
Really? Is the one you got for your friend holding up? I have a few that I use and they have all out lasted my 8-9 hour days; maybe its because my FF is smaller. If you want to try another lmk, I have a few more I can spare. I’m abandoning my plans to install a trolling motor so I don’t think I’m going to invest in lighter batteries at this time unless the price is too good to pass up. Text me when you have a price.
