Dude, this is Awesome. I made a 48V 30AH battery using four 12V 30AH lifepo4 batteries from globalbatt on e-bay. Just ran them in series connection then connected it to the solar input on the bluetti ac200p and the bluetti solar charger to it, the AC50S. I run my whole cabin off of the AC200P with a total of 22.5 KW HRS of lifepo connected to the mains on the motherboard VIA xt90 Y-Cable and an Renogy all-in-one 80A solar charge controller. I have 5,900 watts of PV here in central Texas. Battery gets topped off by noon on a daily basis and the ac200p reads the battery percentage correctly too.
neat buld.I made a few ammo can battery's. but 4S 12.8V . did not use bluetooth in metal one. I have 50Ah cells in 50cal one. BMS with balance. used Anderson power pole connectors with meter. and master switch and fuse. have same binging post . I used KEP nut. I made my buss bars with copper pipe I flattened down in shop press. and tinned them. Try cutting a rubber mat for the bottom. 😊
Ok, I think you win the suggestion with the rubber mat. Great Idea! I was concerned about the Bluetooth signal getting through the metal, but I remembered SOK, and a few other metal cased batteries were doing it fine so I went for it. Sure enough it works fine, I was even connecting to it from inside my house. Those sound like some awesome ammo can builds you have! I've done that flattened copper pipe, I even made my own nickel acetate to coat them. I have a video on the channel, it was actually super easy. Thanks!
@@BradCagle I do a lot of DIY stuff. I use my ammo can battery 12.8V for HAM/CB/MURS/GMRS radios . take it camping and to park. with solar panel. i got 10 to 300 watt ones in foldable. lot of fun ! ☺
@@robertmeyer4744 Nice, it's fun stuff for sure man 👍
Great and interesting video, like all your videos. Well done!
Thanks!
Great and interesting video😁
that is so cool... you do know that you can get plastic ammo boxes
Yes, I've seen them. Thanks!
Great build! I am considering building two of these for use on a long range bakfiets ebike. Could you please tell me the weight of the completed battery? Thanks!
Great build! What app are you using on ipad?
Very good job man, Enjoyed watching.
Just slap a Roll2Videos sticker over it 😂
Thanks! Yup send me a stack 🤣
@@BradCagle If I had one i'd sender.
What a fit! Glad you put the fibre board on the bottom...had me worried there for a while. Might be a good idea to use the fibre board on top too. Much better than ply I would think.Soldering the BMS leads is, I think a great way to do it - less chance of a failure. Just confirming that the copper wire you used is perfect - you shouldn't pull more than 25A out of that battery. A fuse would be a great idea too as relying on the BMS for protection only works if the BMS is working. Maybe a reset-able type automotive fuse?
Good call on the fuse. I might try to find some thicker fiberboard. The stuff I have is thin enough I think the cell terminals would penetrate with little effort. Yeah, I would normally stay 1C or under, but I might just beat this thing up, I had it sustaining over 30amps last night without a problem, I might push it to 50A, and keep a close eye on everything to see what it will do. Not something I would do on a installed system, but this being a test with me near by I can react before it takes my house out 🤣
@@BradCagle I don't know if LiFePO4's are capable of taking the house out. A lot of noxious smoke, but that's about it as I understand it. Be interesting to see how they go. If you are going to try 50A (I don't if you have an IR device) it would be useful to create a heat map of the cells.
@@BenMitro Yeah, I'm exaggerating it 😂. I have an IR thermometer gun, I can get a rough Idea with. I do need to get a thermal camera.
@@BradCagle Just create an imaginary grid and write down the temperatures in each cell.
@@BenMitro Good idea.
I'd like to replace six 6 volt Trojan T-105 lead acid batteries that are getting tired with something like this as it appears those ammo cans would fit into the separate battery trays on my 1992 EZGO Marathon 36 Volt Golf Cart. I've even tried three .12 Volt Remote Solar panels hoping to gain more range while out on the Sporting Clays Course but I don't think they can keep up with the discharge quick enough to help keep me going. Any suggestions on what you would recommend would be appreciated. I'd like to have something like you have there. Great videos, thank you. Following.......
You need to layer some non conductive material on the bottom, sides, and between cells also. That blue stuff is not good enough.
got a link for the cells
1C discharging rate.?
Cool build. Plasti-dip the bottom edge of that clamp down lid. You dang near exploded yerself! Kapton tape over top of the cells, now that it's all assembled? What do you do with a 48v battery that only has 25AH of capacity?
Good idea. You're right, I did almost LOL
Hi. Hi I tried to order the celles. Got; your order cannot be shipped to the selected adress.....you got a good suplyer that can send to Oslo Norway? Thanks
Hei. Great vid. Where do you buy the batteries from. ?
You can get them here batteryhookup.com/products/new-3-2v-25ah-lifepo4-topband-navitas-prismatic Use my discount code BMC to get some % off. Thanks
the inside of a big old tire would be fine for a soft base ... and 4 rubber legs!!! screwed or even glued
I have something that looks like tire tread on it now. Harbor freight sell this rubber tread as antislip. I just used that. It works great. Thanks
Can I use it on Super73 Ebike?
Yes, you probably could. That would be awesome looking, and very long range 😃
I did a comment, but it's gone now. Get neoprene sheet for the bottom is the gist. Meh.
Nice, that neoprene sheet stuff looks fantastic. I'll see if I can score some. Thanks!
Actually 12v is better than 48v…
Better at what?
