Outstanding information! I'm upgrading my fish finder and this answered my question regarding battery perfectly! Thanks so much for sharing.

No problem appreciate the kind words 👍🏻

Answered all my questions. Nice.

Great explanation.

This is good info feller I have 10 gen 3 and didn’t really no what amp battery to go with lucky I got one that lasts the day 😉

Thanks man really good information.

Great video! I’d love to see a video about how to use fish finders and what the features do. I’d like to buy one but I don’t know what to buy!

great teacher

1.my lowrance elite fs 9 state power draw 2.0a @ 13vdc. if i fish for 10 hours means i need 40ah lead acid battery? how can my elite smaller than yours draw double? 2. i just purchased 12v 26ah lead acid battery and fully charge using bosch c7. but after connect woth my elite the voltage shown is only 12.3v.. is that normal? i read some article it supposed to be 12.6v n above when full charge

For those tuning in to this tutorial, be advised that fully discharging a Lithium battery damages it! You should ideally not let is drop below 20%. Also note the Humminbird unit is an older model, which is why people are trying to correct Thom on the current draw - they are of course looking at the latest version of the Helix 10, with is 2.7A. For hire boats, I use two networked Garmin Echomap Ultras, plus GT-56 and LVS34 transducers, add the black box and that's a lot of amps - hence I now use a RebelCell 12v 70A lithium Outdoorbox. Expensive, but the best isn't cheap.

I have a Garmin Striker VIVID 5CV . I as well would say 12. The finder goes in my boat plus my kayak so weight is key for me. What would you recommend in the lithium? Dakota brand or?

Well explained.

So on my helix 10 gen 4 ive got a 12v 40ah battery but do I need to fit an inline 5amp fuse to the battery on the positive side is it needed

Yes. Definitely.

So you can use any 12 volt battery (4ah, 7ah etc) for the Garmin striker 4?

@Thomhuntfishing

Not ‘any’ 12v battery, you need a deep-cycle (rechargeable) battery (it’s possible to use a cranking battery but not ideal) and the ah is the size so I’m not sure what the power draw is for a Striker 4 but look it up to figure a battery size big enough to last all day

Should I base my battery requirement on the maximum fish finder amp draw?

@Thomhuntfishing

3 жыл бұрын

Base it on the draw for your specific unit. There are ways to reduce the power draw like turning down screen brightness or switching off modes like GPS but for simplicity sake for yourself, yes base it on max draw for your unit. 👍🏻

I’ve got a Lowrance Hook Reveal 7 TS. Would I need an inline fuse to run it off a 12v deep cycle marine battery? The battery has 685mca and 140rc. Thanks I’m advance!

Hi there, I’m not sure on the specifics of that exact unit, but my intuitions would always be to put an inline fuse on the positive wire between battery and unit to prevent any over-voltage issues and damage to the unit if battery went faulty. I’ve seen melted wires and damaged units before from people running direct to battery without a fuse. For fuse size for example I use 10” & 12” Humminbird units which require 4amp and 5amp inline fuses. If you have a 7” unit my guess would be about 3amp fuse needed but it’s important to get it right so deffo look it up in the manual or visit the Lowrance website.

@@Thomhuntfishing thanks! After looking in the manual under power requirements it says 10-17v for voltage input and for fuse it says 3-amp automotive. I’m just curious why it didn’t come with a fuse if it needs one? You’d think they wouldn’t want you frying your unit…

When I get home and put it on the charger do I leave it on until it’s full then take it off and wait for the next trip or do I have to keep it on the charger until the next trip?

@Thomhuntfishing

2 жыл бұрын

If you take it off the charger once it’s full and leave it for a long time then potentially the battery can run down slowly over time. If you have a smart charger it does no damage to just keep it plugged in the whole time and as it slowly runs down the smart charger automatically tops it up

I went to the website you suggested. It says 3.3. You talk about screen brightness, what about the power your transducer uses.

Sorry man, don’t know how to help. I’ve got a screen grab here from the Humminbird link I sent you saying it’s 1.75amps (but I can’t post a picture here in the comment) Literally no idea where you got 3.3amps from for the Helix12 unit, as the Solix12 Mega Si+ G3N only draws 2.88amps 🤷‍♂️ Plus I know it can’t be 3.3amps as I’ve run my day battery for 9-10 hours before, and if it was 3.3amps/hour draw that battery would need to be 30-33ah size, and it’s only 22ah but lasts all day on my Helix12? The amp draw stated by Humminbird that I’ve quoted includes the transducer, as it comes via the unit, the only transducer that requires extra power is the M360 (I have one) but even that with moving parts doesn’t use much. Either way, if you’re still adamant it’s 3.3amp draw, you can still use the equation I’ve given just make sure you get a large battery! 👍🏻

My helix 10 si on web says 2.7 amp draw. Is that right?

@Thomhuntfishing

2 жыл бұрын

I think the Gen3 & Gen4 units have a much higher draw so 2.7 is correct. I did this a few years ago and it’s the Gen2 unit I think the max draw was 1.4 and I used to run at screen brightness 8 which was 1.05 amp draw. Like I said in the video every person needs to work out their own equation based on their specific unit

Hi. Can you use a car battery to power a fishfinder?

@Thomhuntfishing

2 жыл бұрын

Yes and no. There are 2 types of lead acid batteries. ‘Car batteries’ also known as cranking batteries are more for delivering higher amounts of power over a short period to start a car engine. The car then has an alternator which recharges the battery as they are not designed to be run down flat. Alternatively, a ‘leisure battery’ also known as ‘deep cycle batteries’ are better for fish finders and trolling motors as they are designed to be run down and then recharged when you get home. So if you have a ‘car battery’ that starts your boats motor, and an alternator that recharges the battery then yes you could run your fish finder off this system, but if it was a car battery just rigged to your fish finder then no, the battery would die very quickly. In that instance you’ll need a deep cycle battery 👍🏻

Hi I would like to run two garmin 95 uhd chartplotters at the same time and it draws 1amp per hour and fish off different boats every time I go fishing so if I bought a peli case how would you suggest I wire them up together please , thank you

2 units on the same battery is simply attach all +ve terminals to +ve….. and all -ve terminals to negative and away you go 👍🏻 I’ve heard of fish finders and trolling motors being on the same battery causing interference but 2 sounders on 1 battery is fine

what do you mean "Li ion is *very expensive* "? A 20Ah is ~200$. For the money we spend on reels, rods, lures, technology itself + the FUEL, it sounds fair.

@Thomhuntfishing

Made this video 4 years ago when it was very expensive, and even though prices have come down, compared to a standard SLA battery of the same spec, LiPo4 is still roughly twice as expensive so yeah given the choices on the market it’s an expensive option

If your 12” humminbird unit uses 1amp it’s broke. Should draw 3.3 amps.

@Thomhuntfishing

3.3amps? Where did you get that from? Here’s the link to the spec page of the Humminbird website.... which says it draws 1.75amp but that’s at full screen brightness. I’m normally running screen brightness 7 which is is 1.1amp (I should know, I’ve tested it) but for simplicity of explanation I just rounded it to 1. humminbird.johnsonoutdoors.com/fish-finders/helix/helix-12-chirp-mega-si-gps-g3n?jo-page=2

Amps per hour. 👍🏻😂 I was trying to differentiate between useage/draw and size.

Never run a lithium to zero it will degrade the battery so badly, although most lithium batteries have a cut off somewhere around 20% or so but never zero
