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 35.com 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.
