Awesome. Glad to see someone else works the same way I do: "yeah, that'll work fine". Not everything needs a fine finish, right? Sometimes a tool is just a tool, not a shelf piece
As an owner of 3 dead jump boxes, I am seriously digging this. I just so happen to have a pile of 6 cell drone batteries and charger so I guess it's time to crack one of those POS open.
I purchased 48 of those cells from battery hookup. LOVE THEM!!! Didn't care for the grommet connection so I used 2 - 5/16X3/8X3 inch aluminum bars with #10 screws to sandwich the tabs. Can't take credit for the idea. Saw someone on youtube do it and felt it was a better connection. Also easier to hookup the balance leads and output leads. I've been following your kayak builds and am impressed so far. Hopefully you have a new video for us on the wife's dual motor setup.
That's a nice little project. I held my breath when you started punching holes in the pack... awfully close to the lithium. That would have been something of a new years show. :-) Happy New Year buddy!
Positive to negative, positive to negative, builds voltage, like 12,24,36 and so on, hooking two or more batteries positive to positive, negative to negative builds amps.
Happy New Year! Jehu has a really cool channel...not as good as yours...but he mostly specializes in batteries so it's all good :) I would go ahead and put a grommet in each of the two "ear" tabs as well...it will help with the higher amperage delivery.
Reverse charge protection would be good, I.E. when the alternator is charging the battery after starting, it could over charge to battery pack or apply significant undue stress on the cells. Probably enough to keep the pack voltage that above the alternator voltage when charging a dead battery.
Ideally you would want a little spot welder to weld those connectors together. Especially when pulling hundreds of amps through it you want slightly more than the rivets. Although... they'll probably weld themselves together under load anyhow :P
These high current batteries need space to expand while charging/discharging. That's why they have a lot of room in the original case. When you don't allow the cell to expand properly, Samsung Galaxy Note 7 happens
I was waiting for the bang when you punched holes while resting the punch on the tape below The one thing they shouldn't have removed from cars is the starting handle, often you have enough power to turn it over a few times, but not enough to start due to the starter motor taking the power.
I recently purchased a lithium jump pack, my only concern is that they use a dc-dc converter board to up the voltage for starting- why on earth would you do that, when you can get a reasonable 14.4V from the right count of lithium cells, and its a lot less complex, you can then convert the voltage down for your 5v output as a battery bank. personally I favour your approach.
I am not sure what the battery chemistry is ... Non-LiFePO4 lithium polymer cells get hot when you charge or discharge them at a high rate. When the get hot, the polymer expands. When they get really hot, the polymer bag can pop and now you have a problem. High discharge for a brief period of time is not an issue. Use cautiously !
Bloody awesome video! Do you have information or link to where you got the batteries and build-kit from? My mind gears are churning up a storm of projects. Thanks a lot, mate.
I found the problem with jump boxes or as we call them booster packs they come as just booster packs or with air compressor or modified inverter for year's I bought them for running a drill and when cordless tools came out to charge the battery packs but their life was short usually about a year hated to throw them away so into storage they went then I found utube and videos on how to properly treat sealed lead acid batteries simple things like keeping them fully charged don't discharge below half and. Every time you take them below dead you shorten their life then they shocked me a 12 volt battery is not 12 volt but 14.8 so half is 13.4 and dead is 12 volts I thought they were wrong after all wouldn't the booster pack manifacture know proper charging and discharge perameters most of my inverters shut down at 10.8 volts but I had my old black and decker handy so I opened it up to find out who made the battery and find their website to find out what their charging perameters was but didn't have to as written right on the battery was do not discharge below 12.2 and float charge is 13.4 and full charge is 14.8 and on the built in charger was output 12 volt so no wonder it died it was dead to start with and was being discharged way too much sometimes to completely dead since I have a pt cruiser with a glitch I had just purchased 2 everstart booster packs so I checked their charging perameters and found that they were better charging to 13.1 so I phoned them to check and was assured that it was fully charged at that voltage but a year later I noticed that they were doing the same thing as my other ones did amount of boosts dropped from 5 to 4 and shortly after to 3 so I hooked up my good battery charger to the booster cables turned on the booster cables and plugged in the charger it got it to 13.8 or 90% and couldn't get it to full charge but after a few uses and charges it finally got it to 14.1 and said it was full but after another year it looks like it's now died but I also found that the rest of the components were garbage one compressor didn't work and the second locked on so I had to open it up and cut the wire but thanks again to utube I found I can rebuild some of my old units replacing the battery and I can while I have them apart upgrade them adding USB charging basically turn them into solar generator but I'll have to see if I can change the charging perameters or put in a port to charge them with a good battery charger after watching utube videos I found that with a little modification I can put in a bigger battery in some units.now if some company will bring out a circuit board to change modified sine wave inverter to pure sine wave that would be great I'm told that a product from Triplite called a line conditioner lc1800 will do it but while they are reasonably priced at under a hundred dollars in the USA up here its 138 dollars Canadian still reasonably priced but at almost 400 dollars shipping costs its cheaper to buy a new pure sine wave inverter
I'm looking forward to seeing the fully finished jump pack. My jnc770 is 4 years old and still going strong after tons of use. But I'm starting to look at options.
11:13 The diagram shown is for a 6S pack, but the battery being built in this video is a 4S pack. I'm sure anyone using this video as a guide could probably figure out how to make the mental image adjustment from 6S to 4S. Also, dont listen to me, I'm just a big dummy.
I would have like to see if you could have made the old system work first before the battery upgrade I was wondering if it only the connections good job but beware
Looks like sealed lead acid batteries ... It needs to be charged once a month for a proper use ... Self discharging 3% a month . They are quite good usual stuff but unlike usual car batteries you cannot change the liquids in to charge these back ... Once totally discharge there quite almost no chance any to be charged again ... But, ... Ain't lead buyed at its right rate at this time ???
Can you not keep the USB and DC plugs...I have a beast box 15 in1 .... Has DC in outlets and air pump and solar panel trickle charger..... Can I just pull the lead acid battery and plug this up to it and it still work?
Those kind of cells look a lot like the kind that were blown up like balloons in my Macbook air that was in our garage looking for a screen to replace the crappy Apple paper thin glass one. Here in Finland a couple of years ago the temprature dropped very low down in that part of the house briefly went below zero. In spring when I went to fix the laptop screen the whole thing was blown up like a balloon. Just wondering how those cells you are using cope with cold?
You shouldn't have made this video. I have like 2 of these and my father-in-law has like 5 of them and I have a UPS battery for my computer that bit the dust. My mind is spinning!!!
@@TheGoodoftheLand I feel silly for not thinking of this idea already. I follow Jehu this was a great idea to make something that already exists significantly better. I can't wait for the next episode! I will definitely put this to use. I appreciate the inspiration.
There's a small error in your calculation. Putting batteries in series adds up the voltage, not the amperage. It's the other way around when putting them in parallel. So your pack is only the what ...200 ish amps now. Still more than enough!
lithium batteries like the pouch ones when they go bad swole Round up to 4 times lets say all his puches go bad at the same time that plastic jump box would explode cuz all those batteries would end up as a Basket Ball but it will take years
I have to correct you, no offense intended. Just don't want someone who is doing this to have incorrect info. Alot has changed in the lipo world. These will not catch fire on a direct short and will not expand. They will vent but it is not violent. Hope that helps.
@@TheGoodoftheLand cool i didnt know that thanks ! i have emergency lights , those were lead acid gel and went bad maybe i will replace with lithium then
@@fergabmmx I put a link for cheap lithium in the description. There batteries were only four buck a piece! They sell best systems that are very easy to wire. Great option for what you need.
I like this with the grommets. I learned something. Thanks
Thanks for making this video. I have everything laying around to do this to my dead jump boxes. They were in storage for 8 years.
Awesome. Glad to see someone else works the same way I do: "yeah, that'll work fine". Not everything needs a fine finish, right? Sometimes a tool is just a tool, not a shelf piece
Dam, going to have to build me some Lipo batteries, looks like a winner 👍👍🇦🇺
Very nice jump box. I can't keep them over 3 months around this place. Looks like I'll be building one or two. Thank you that's some great information
COOL STUFF MAN

For a sec I thought I was missing your notification but you've just slowed down the content cant wait till it gets warm more of the canoe vids
This doesn't sound like a resounding endorsement for MATCO.
Man I need to make one really cool

can you put a link to the battery source. The battery site listed doesn't have the battery you are demonstrating
Give them a call. They have a ton, just not listed. They have to be unpacked.
@@TheGoodoftheLand what are these batteries called?

I hadn’t considered expansion, personally I was worried about heat dissipation stacking them all together like that.
Bummed the kayaks caught the back burner!!!
It's coming back!
where can i find these cells
Is it possible to charge the battery with an external charger but through the crocodile type cables?

Just subscribed came over to check you out at the subjection of talking loud Steven Cox. LoL like his channel. And seems you have a good channel also.

What kind of batteries are those? There was no kinda circuit board or anything necessary?
I wonder if there is some way you could extend the handles on those crimp ring pliers? (Trying to get a bit more leverage out of them.)

High discharge for a brief period of time is not an issue. Use cautiously !
Look up these batteries. They are impressive. Lots of testing on TH-cam including a short to ground test. Check out Jehu Garcia.
Not saying there is anything wrong. Just use cautiously.
I understand.

At 14:40 you can see a wells vert mill!
No we're near 800 amps bud. When in series the amperage doesn't increase.
