Sweet video! Maybe a consideration in the future would be something to lock the cells into the holders to reduce the possibility of one getting dislodged...
You char a 24V pack with a 42V wall wart charger in your description? Isnt that too high of voltage? Where would you plug it in? I’m assuming youd have to cut the connector off and connect the wires directly to the terminals? Hassle...
been looking around for months and its the first time iv seen a kit using this plug in battery board whilst everyone else is welding them together with car batteries or a microwave transformer.
I love this! I dont wanna mess with building a battery but i wanna add 2 ammo cans to my ebike (saddle bag styt) for some extra range/back up get home power.
This definitely looks easy enough. I'm planning builds of similar cans like this (some will be powered off power tool battery packs instead of straight 18650s), but not with the intent of it just being a battery, but having integrated power connectors (USB, 12V, etc.). Along with integrated terminal connectors like shown here so I can connect an inverter - e.g. to recharge camera batteries when on the road.
Jehu, Thank you for creating great content! I am not an electrician but I look forward to building a power wall at my house soon. Thank you for the inspiration! Gracias por ser un ejemplo para todos los latinos que si se puede! God bless look forward to your future vids!
Would love to see you do a DIY version of Milwaukee’s new MX Fuel power Station they’re coming out with. Looks cool but they’re probly going to charge minimum 2 limbs for it.
Lamentablemente, lithium batteries are no longer shipped by UPS, DHL, USPS to Puerto Rico. That kit looks really nice and convenient for building 'solar generators'.
I bought and built one. Are there any recommendations on a 24v charger to use to charge the can? Will any 24v charger work or are there specific requirements. I did not see this in the video.
Cool project! Just out curiosity, apart from the fun of putting one together, how does it compare to LFP 100Ah batteries? In performance? Cost with new cells? (LFP 100Ah are getting to $700 range)
@@htmagic I need it for an E bike, 1 50 caliber can would be the perfect size and container. My current E bike battery is 48v, 20AH which is about 1kwh and is approximately this size.
I think you should be able to make it 48v All you have to do is make it two towers inside the ammo can with bms pcb per tower den connect +to- and you'll end up having two +and- ends
@@jehugarcia Will the batteries stay seated if the case is banged around or vibrated in vehicle? Should I wrap kapton or zip ties around the battery modules?
My biggest concern would be those energized standoffs shorting out on the metal ammo can if one of those nylon standoffs fail or come loose. I would think that a plastic insulated case would be more safe. I wonder if coating the inside with a liquid rubber spray on or brush on liner would be more safe.
Insulating paper (fish paper) for building battery packs or a thin and durable plastic such as polycarbonate/Lexan are some ideas that come to mind. They can be glued to the inner surfaces. The local hardware store is a treasure trove of ideas. The other thing to consider is heat when charging or discharging. It would probably be best to open the lid while in use.
I've seen you use a Lithium battery tester in at least one of your videos, but I can't find it. And you don't sell one on your site. Can you recommend one that will help test the capacity of a bunch of batteries quickly? I don't intend to buy many, but I don't want to spend weeks testing them just to build one battery pack.
Ok okay I’m currently converting a gas motorbike into a cafe electric swap...I’m thinking about 72v minimum....I’m guessing I’d have to drill holes in the kit for cooling then right?
Cool. You should do a throw-back tear down of the Monoprice Obsidian Speed Plus Power Bank USB Charger 6700mAh. They are only $8 new right now. Looks like two 18650s, might be a good chance to explain the economics/harvesting of simple battery banks. ✌️

@@christianlefler5240 My understanding is that each board is giving the nominal voltage of 24 volts and then they are linked in parallel from there to just increase the battery capacity.
I was searching, and searching but can't find a video where you test used 18650s both capacity and IR and say something about it, like what is acceptable range or difference in voltage, capacity and resistance that you would use that cells for a battery pack.
What configuration would you suggest for a lack to run a pair of 120v tools at the same time, and last for at least 30-45min per charge? I have a mitre saw with 15amp motor at 1600watts and a Dust collector at 8.3amps and 1200watts.
If the total capacity of the battery is around 1kwh of energy and your refrigerator uses on average 100 watts per hour than it can run for 10 hours, it’s all math.
I follow your videos regularly. I have one question, I want to install solar offgrid system in my house I have 2 options typical lead acid 150Ah tubular battery or diy li-ion battery. I am getting the lead acid batteries with approx 1500 cycles life span please suggest. Thanks
This is probably a dumb question but 100 watts is 100 watts regardless of voltage right? So if I have one of these and let's say it's built out to exactly 1000wh so a 24volt 100watt "bulb" would run 10 hrs right? If it was stepped down to power a 12volt 100 watt bulb it'd still just be 10 hrs right?
The question, why all the sellers make adv only showing battery voltage, capacity, and energy? Why not say the power supplied? because vision batteries are electronic's batteries, right? So, those batteries different from lead acids battery has a limit of power due to BMS and even the cells limitation. I appreciate your thoughts and comments. Thanks Rodrigo Koji Nishigasako from Brazil.
Because the seller of this item is not thoughtful enough nor does he really care to be honest. Having a sale is his priority, not the descent amount of honest informative information.
Right, but in other hand, the seller would suffer in a warranty for miss information by himself. So, not a good deal at all. Better to inform the customer what would be the maximum power capacity is allowed to drain from the battery, correct? I appreciate your comments. Thanks Rodrigo Koji Nishigasako.
Seems like a lot of labor to send it out premade and assembled. Couldn't you stuff it with cells when building it to capitalize on the labor? There is a loss of labor on both sides.
Well I really like the idea, but WHY??? WHY did you drill holes in there? I mean, for the power connector, ok. Those can be sealed, but why put them in a sealed ammo can in the first place, if you drill holes in it? You can press fit the cell holders when closing the lid. That will be more than enough.
