All right, today's video is gon na be short um. A lot of people are buying these uh obx-e batteries right. These are 16 volts, uh, 5s lithium-ion phosphate right, and so what we're doing is uh a lot of people are using them to power their. You know their blue eddies or their uh equal flows or whatever some some stuff right, they're building either that box there's a bunch of projects that use these, but people are saying some of the so a lot of the people that are getting these are first time Battery builders right and because these are so easy, they're already put together um.

Well, sometimes they don't have maybe like a multimeter right and sometimes i'm like in some of my instructions. I go just measure the voltage and, if it's this and that you know - and so something that sounds really easy to me - it's it's quite hard right, uh inconvenient for someone that doesn't have uh this tools that you need to do to work on batteries right and So it's okay, you're, just gon na build a one battery and you don't wan na, buy a thing right and then what i ended up doing is making a little piece here, a little board that has some essential things just to try to make it easier for People right so what you'd have to do is get a voltmeter right, a multimeter and then learn how to use it and then do the thing and then you'd have to get like some kind of kid. This type of connector here, which just has a weird name and it's hard to find, um and then you'd, have to make some kind of cable to charge it right if you're gon na charge a bunch of them. So i just went ahead and made this board right here, and it's got some instructions here says for to use for that.

Obxe 371 hour battery packs found in jack 35 instructions can be found uh on this address right and i'm just gon na put this video in that address. So this little board here what it does is - allows you to use a 18 volt 2 amp charger to charge your battery right. So usually, i would say, just use this board or use this thing to charge your batteries. But the question has been: how do we know when they are charged? How do we know like yeah, because these this might be close to being charged or close to being fully discharged right? So it might take 10 minutes to charge one battery right if it's almost fully charged or it could take, maybe almost a whole day.

This is a big battery and this is a small charger. So this thing will allow you to do that, because all you have to do is connect it right here check it out. It's got that same connector bam right and there we go. You get the voltage 16.7, so this battery is not fully charged until it reaches around 18 volts.

That's why we have an 18-volt charger here right, and so this also just has the connector to be able to use this off the shelf. You don't have to do nothing, you just plug it in there and you plug this into the wall, and then it starts charging. When you see this reach 18 volts that battery's charged and then you can keep going if you're do using multiple of these batteries and then now you know they're all fully charged to 18 volts, and now you can connect them together. If you're gon na do a multi-pack uh battery right, so that your, if you like that one over there, it uses three of these in series and three on these in parallel, so it uses nine total of those right, and so they have to be balanced before You plug them all together and this little device here will help you do that you can find this at jack uh.

Thank you for watching this video we'll see you guys on the next one and keep building. Remember these batteries. Uh are amazing. There's never been a better time to build batteries because they're, you know super affordable and they're everywhere right.

So there we go. Thank you. What see you guys? The next one bye.

    oi' I bought a few battery packs that look just like this from your site a while back that were 12v. So I would need a 12v charger plug? Or will the 18v also work?

  2. Avataaar/Circle Created with python_avatars Michael Morrison says:

    You ARE the Ultimate Plug and Play MacGyver when it comes to all the different battery types and how to use them! Thank you for sharing your knowledge and understanding for the rest of us!

    Hi Jehu,
    Would you be able to do a video or recommendation for those of us who own a Costco Cyberpower 1350VA too extend its run time.

  4. Avataaar/Circle Created with python_avatars Chris Lewis says:

    What is the part number of the 6 pin connector on the circuit board? I been working on a project that needs that connector and can't find it anywhere

    Great idea, even if you do not have a meter, you do not have the plugs or cannot fabricate due to no soldering skills, keep heading this plug and build direction and people will buy the accessories and make your and their life a lot easier, keep heading in this direction and more people can be involved, do not listen to the naysayers, they live to criticize rather than innovate.

  6. Avataaar/Circle Created with python_avatars Peter Hancox says:

    Ah, plug the charger into the ‘mains’ power BEFORE you connect it to your battery. IF the charger has some ‘smart’ circuitry to control/regulate its output, better to get into the habit of doing it in this order.

    out of the 6 packs i bought from you jehu only 2 got to 17v. the other 4 only 16.7-16.8 is that bad? should i charge them again? my kilowatt meter only charges them at 4w after a few hours, does it mean they are full?. i bought the charger you have, 18v. 2amp charging at 37-41w

    @jehugarcia – that’s a standard 6-pin Molex. Commonly used in PC gear like motherboards, backplanes & GPUs. Loads of pins and blank connectors out there! 😁

  9. Avataaar/Circle Created with python_avatars Ecospider5 says:

    I think this is a great idea. Also if they don’t have a multimeter they probably don’t know how to protect circuit boards. Are all the powered connections covered so the can’t short out?

    Man, I gotta just say, if your buying or even playing around with batteries like these, you should've already had a voltmeter or dmm… I mean damn
