Very nice power box, well designed. As a Ryobi user, I built a Ryobi 4-battery box similar to yours. I added an outlet coming off the 18v before the buck inverter to give access to the full 18v. I also added a powerpole plug-in (pp30) for each voltage level to give a way to connection other than the cigar outlet. the battery gauges are a nice addition. You do have room to add a small (200w?) inverter. I found that to be useful now and then. I have several videos about tool battery operated units, including the power box, if interested. You're off to a great start in RUclips. 3 great videos in a row. Welcome to the world of YT creators.
Thanks! I kept this simple it did its job though. I have a 200w inverter still in the box I never used. Wasn't sure if I wanted to add that or another row of batteries. Decisions, decisions 😄
exact same way, just a different battery holder and maybe a different shape for the box if they're wider or longer batteries. I'm surprised more people aren't doing this since everyone owns tool batteries and they store a ton of energy
well i have power banks i build have 12 volt small battery 12A 20hour and have 2 18 volt lithium battery with 3 usb port wich 2.1A and 1A each to charger my phone 12volt lead acid battery with 500 watts inverter with two switch and 2 110A/C out let 15A out to charge laptop and battery meter and volt meter one tell how much % and volt battery
(25pcs) 15SQ045 Schottky Diodes 15A 45V, Diode Axial Schottky Blocking Diodes for Solar Cells Panel a.co/d/hz52ir8 This is what I used. I need to make an updated video. Lots of questions about these
the makita batteries don't have bms for low voltage protection. I wonder if you could add in a relay on the battery source to shut off below 15v so the battery won't get destroyed.
The circuit wouldn't be too difficult to make. My 5aH batteries seem to turn themselves off at low voltage. I haven't fully tested that or tried any other lower capacity batteries. 4 batteries seems to last a long time. Definitely worth making a 2nd video I think. Great idea!
@@TechNTorque Yeah, I saw a video where someone took a cheapo 5s 20amp bms and connect resistors across all the balance leads so the end result is the discharge mosfets would cut power at 15v. You get all the features with the bms except for cell level monitoring.
Not directly. The power I'm using from the solar controller will turn itself off at low voltage, and the power inverter has a built in low voltage shut off. Should be enough to cover my needs 🙂

Any blocking diode will work depending on your amperage requirements but these worked for me. I'll put the other links in the description soon. Thanks for watching!
The outlet comes with a gasket that seems to work pretty well. Not sure I'll ever be stuck in the rain with it but eventually if I add an inverter or another row of batteries I'll completely seal it so I never have to worry about it.
What diodes are you using? Would it matter for them to be any different, say, for my 18v majors packs? Having a hard time understanding how diodes are wired also. Only in the positive?

Could you make a 2.0 box and video step by step making it plz. With capacity for *8 batteries,with low voltage cut of protection. *Inverter 2500w with 2 outlets on the side of the box and switch to go between 12v,may as well add a few usb outlets a type c and a. *Solar charging in the box 450w limit. Just an anderson connector on the outside. N id buy one postage would suck (im in Australia) so would need a 240v inverter.
You'd need a much bigger case for a true 2500 watt inverter. Even then 8 batteries couldn't support it for more than a minute or two. Would definitely be a waste of efficiency at lower wattage levels
I'll be making update videos soon. Just moved into a new house just getting settled. Check out my truck toolbox video I have a 2500 watt inverter in that one with solar on top. Not as portable but it can support the loads a bit better
awesome setup im trying to build one similar, are you worried about killing battery packs? with no low voltage cutoff protection on them? seems that if one pack falls below 2.5v it could keep draining it and damage it.
With the diodes it'll pull from the pack with the most voltage first until the voltage is balanced between them all. The individual cells hang out around 3.7v the longest, so it doesn't draw from the highest voltage pack for very long. I'm making another version with lvco. Should have it ready after new years.
@TechNTorque oh OK nice! Would it act the same if you use different ah batterys? Say like 3 5ah and one 2ah? Would it eqlize them? Please post your new one I'd love to see please. What's ivco?

@@TechNTorque I was researching projects like yours. You did a great job. I found an inverter that is 18 volts on ebay. However, I don't want to limit using the inverter somewhere else.
@MrRChitty you might be able to find more powerful adjustable buck converters too. Just make sure the input and output are in the range you need. I wouldn't buy a special 18v inverter, I like to be able to remove it and used for something else as needed.

I need a video on how to install the Dios
If you were here in North Texas, I would pay for a class on how to do that using my Milwaukee batteries! Great video!

Nice build. I like the truck tool box solar setup also. .
Thanks! More update videos coming when the snow finally stops 😃
Dude!! THAT is nice!! Thank you for making this and sharing to the world of RUclips.
Thanks I appreciate it!
Very Nice and simple (but still smart) design of 12V power box.

very very nice all need is some inverter in it like 1000 watts pure sine wave cool love it i build some of own not finish as yet
Hey it would be awesome if you didn't video on the wiring process and yes how the diods were wired into the wiring harness for the batteries
@@brianbowles99 I definitely should. I've gotten a lot of questions on this
Can you show us how you connected everything like a wire diagram or even better step by step?
@@unbebe1 ill have a video coming soon!
You just splice in the battery level indicators before the diodes? Where does those grounds go to from the indicator? Nice build!

Love the truck setup even more! I built a dewalt one with dewalt tstak case really for GMRS radio or emergency 12v to go box.
That’s a nice set up. Appreciate you showing it. I do have a question. Do you have a low-voltage shut off set up for your batteries?
Not directly. The power I'm using from the solar controller will turn itself off at low voltage, and the power inverter has a built in low voltage shut off. Should be enough to cover my needs 🙂
Could you please share a parts list. Looking for what diode you use to stop back feed for batteries. Thank you for sharing!

u can make it waterproof.. use silicone around the leds, and the outlet

Fair enough as big as an inverter as possible then maybe 1000w
600w minimum.
