How to BUILD A LITHIUM POWER BOX For ONLY $36! 

Sorry man. My bad.

That's why I tuned in but I learned a bunch & how to spend more money on my creation

As the video says you can use any battery. You can also get an attachment to use one of your lithium batteries from your cordless drill. Dewalt, Milwaukee, etc. Almost everyone has that already. You dont need to put a Dakota Lithium as stated in the video :)

Amazing! 3.99 is a great find!

Those are great suggestions!

Noted!

😂😂 that's what I was thinking!

How do you charge the battery?

I just connect my charger to the red and black post and turn the switch on and it charges

Thanks man! The dakota was from my old ice fishing graph. If I didn't already have it I wouldn't use it. I would use a drill battery. Best part is you can adapt these to whatever you use. Can customize.

Pretty straightforward. Connect all positives and connect all negatives

I had someone build my first one and it broke. I offered to bring it in for repair. Enzo said I had to ship it to him. Shipping there and back would cost more then making a new box. You can also buy an all in one USB panel already prepared wired.

@@FoxFishing4K I'll buy yours... how's $37 😉🤣👍

@@mehlbeck lol I'm not taking the risk. If one of these things burns a house down or a truck lights on fire the builder would be liable. My original was close to catching fire. Hence I built my own and made it secure. Battery in the purchased one was loose and rattling around inside lol.

@@mehlbeck if you bought a power box make sure that battery is secure.

As stated in the video you can use a common lithium drill battery you already likely have.

Thanks for the feed back!

I connect to the Red and black Teri also on the outside of the box and turn it on. It's starts to charge at that point.

I clip my charger prongs to the positive and negative bannana plugs sticking off the box, and then I turn the box to on. Will charge without having to have to open it.

You can't overdischarge the battery. It's lithium. Just like using a drill you have full power then boom instantly dead. I run all my lithium until they run out of power and have never had an issue.

it has a bms built in for protection

Like the other person commented these batteries have a little built-in circuit board with chips that cut off the battery at a set voltage to keep them from being discharged below a certain level so the battery won't get damaged.

Oooh thats cool!

Lol I am not. Super easy though.

Lol I hit my knuckle on the edge of the box trying to tighten a usb socket. I actually slowed down footage to try and show the hit but you couldn't see it.

lol you noticed my hand did you!. Hand healed and box is working great still. I did change the power switch to a water proof button rather then a switch so it cant get bumped and turn on or off while during transport.

Nope likely fine. I wouldn't worry about it. Maybe it's reading the draw from it while in use?

Turn the power switch on for the banana posts and clip to them and it will charge ;)

Do what you feel is safest :)

I could help sure. If your local bring it over. If not text me 705-937-8558 and i can walk you through how to fix. I originally had a Lake Simcoe Power Box but it was made terribly and fell apart in like a month. This is why i built my own.

Yes they are LOL

I think the battery was on sale for $98 it was a 12ah Dakota Lithium.

It kills the power to all the switches and everything so you don't get battery drain.

The gold would be negative for the neon light on the switch to work. The switch would work without the gold being connected to negative but the neon light on the switch won't work

Unfortunately I use mine all the time. It is so handy!!!

That fine and thanks for the link.

Just connect charger to the postive and negative bannana clips on the top of the box and turn it on.

I don't run a fish finder off of it because my graphs have 9" screens and require a lot of power. They all have larger lithium battery of there own. This box is built small so I can take camping or bank fishing.

Most are the same parts that are on Amazon.

@@FoxFishing4K aliexpress just cuts amazon out of the middle man picture. Same country of origin.. With that said, I'd wager any of us would be hard pressed to find any of these parts made in the usa or another country of origin. It's just the facts of today..

@@skelafeti your right. I don't mind paying a bit of premium buying locally. But when stuff is $1 in China and $15 here that's brutal.

Mine is a Dakota Lithium, and I bought it at Cabelas. You can get much cheaper brand Lithium now, though.

replay the video. he described the wiring in earlier in the video, and in the end, he just assembled everything. Great project for camping etc. and unlike other projects on RU-vid, it do not require a forklift to carry around. 🙂- Have a nice day

Yes it was!!! Plus at bare minimum for safety reasons I would use shrink wrap over each terminal into each switch or plug .

smart!

Charge at the terminals. Connect your charger to them and turn the switch on for those and battery charges. Once done turn switch off and done!!

Thank you. The box is still going strong and i use it all the time!

Connect the charger to the red and black posts on top of the box and turn the switch on.

Connect the charger to the red and black plugs and turn the power switch on for those plugs. It never has to be opened.

SHHHHH My wife will see this. I do this stuff while she is working night shift!!! LOL

Weird. Was the battery charged? I only run lithium. It's either full charged or dead lol

I think it was 16 Guage.

Amazon even has all switches and USB all done for you. It's a little more but plug and play. :)

I mean no water proof box, toolbox for example, to water proof

I think it was 16 Guage wire if I can remember correctly

Awesome!!

I can't remember lol. I will check the box and let you know

I think it was a 15 though

Yup that's what I'm using your video was the best that I seen!

How are you changing the unit?

@@vladimirangel7226 I turn the switch on for the posts and connect the charger to the positive and negative post :). Super simple and never have to open the unit.

Sure! Good idea! Soon as I get home

Posted. Its in video description as well as a comment. :)

The switch on what? The box, or the charging unit? Also you must have bare wires or crimped terminals from the charger, right?

Connect the charger to the positive and negative posts on the top of the battery and turn the switch on.

No worries! Thank you for the kind comment!

Lol screwdriver slipped and stabbed my knuckle lol

Thanks man!!

Awesome! It will save you so much money as well!

There shouldn't be any drain with the inline switch turned off. The only drain would be battery discharge over time which is normal.

Smart man! I have those as well. I need more power for my otter lights and gopros. If I didn't then the smaller portable power banks would be perfect!!

Thanks for the wonderful comments.

They are annoying but cute assistants!! Lol

Glad it was helpful!

Turn on the power switch and connect charger to positive and negative posts on top of the box

I have a similar build. For mine I have a cigarette lighter male that I can attach to my lithium battery charger. If you plug into the port it will charge

for poor as cheap people like me. you go to Google, and you find yourself 4 used headway cells. you pay no more than 4 dollars eatch for them.

If y'all are anything like myself, I keep on hand at least a dozen 18675, 3.7V. Batteries that I am always salvaging from old or dead electronics! You know like an electric razor, or anything that is wifi! I actually have 3 whole sets of electronics from Ear Buds headphones!! With a tiny tiny lipo battery and wifi circuit!! I also take any solar panels. Those are always still good !!

You can use a drill battery you already have at home ;)

Need a lithium charger for lithium battery. Turn it on and connect charger to the banana plugs and done. Don't even need to open it.

@@FoxFishing4K I understand the process. I was simply noting that you never mentioned what type of battery charger to use with it. If someone who doesn't understand LifePo4 batteries builds your project, (a very fine one at that), and tries to charge the battery with a standard power supply, car power socket or car battery charger, they will wind up with a pile of HOT orange goo where the battery box used to be and / or possibly even a very hot fire that is next to impossible to put out. Lithium type batteries are no joke and need to be used with care and respect. I was encouraged by your use of a fuse. I'm guessing by your accent that you are Canadian. A little tip for you and your fellow countrymen / women and my country people to the north of me. LifePo4 batteries can NOT be charged by ANY charger or solar array if the cell temperature is below 32 degrees F, (0 C). Permanent damage to the battery will result. it can be used cold but not charged. It must be warmed up first. I say this for someone who may go ice fishing and leave it sitting on the ice or may leave one in a car for emergencies in the winter. Larger higher quality, LifePo4 batteries for solar, marine or RV use have a BMS module or Battery Management System module built into them to protect them from overcharge, undercharge, low charge condition, (below 20%), short circuit, excessive high drain and high and low temperature conditions. It is not impossible but unlikely that your battery contains a BMS module and more likely contains just raw cells in a plastic box. This is not a bad thing but requires more care when charging. Other than this, it's an exceptionally well done project.
