LifePo4 6v 12a Batteries - Kayak Fishing Adventures on Big Water’s Edge

Greg, do you happen to know what the output is on the charger that comes with the battery? I'm wondering if the one that I have know is to much for it.

I also run my FF on Lipo polymer 4 cell batteries. These are 14.8 volts W/battery monitor.

Hobby King Battery Monitor 4S
Accurate and easy to use, the Hobby King Battery Monitor 4S will give a warning buzzer when the Lipoly pack drops below 12v.

These light weight batteries 5000mah will give me over 18hr of running time on the FF.

The yellow case is water proof. I made sure the outside connection are also waterproof. Running your FF and bait tank on lithium does have its inherent dangers, but the lifepo4 type batteries are much safer.

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.

Or you can always buy the extended warranty

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.

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..

FishNinjaY, my FF needs 12v, most do.

GregAndrew · 06-25-2013, 08:48 PM

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

Jorge,

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.

GregAndrew · 06-24-2013, 09:43 PM

Yes, what John said. You need a special charger for LifePo4 batteries which are not the same as Lipo batteries or lead acid batteries.
