I would like to see some longevity tests on something like this. Some cheaper ups units will actively use the SLA battery to smooth out the output voltage, this might cause excessive wear on Lithium based batteries.
Nice video! However, your XT-60 is not mounted correctly. It’s supposed to be mounted from inside. So that the screws used on the outside pull the connector tight. Also, the XT-90 version is a better choice for more current capacity. I’d love to see another 4 LFP cells in that box.(4S2P) for greater overall Watthours. (Ie -more capacity). Try staggering the cells instead of the “flat” matrix. If the box needs to be just a tiny bit bigger, it would be worth it to have double the capacity, and double the current delivery. Great job with these. Keep up the good work.
I like a lot of this. But some of those cold solder joints are scary. Also, traditionally XT60s use the female connector for the battery, which is more protected.
Well done! I'd like to build one of these to replace the terrible lead acid one in my kids' scooter. I _do_ miss the narration on this video so I hope you'll bring it back! And will you add an Instructable as well? I'm not complaining, you do great work. Thanks!
Thank you for your genuine feedback. I personally prefer voiceovers in my video but sometimes due to time constraints, I am forced to upload it without voiceover.
@@eone2345 I'm curious which cells you used to replace your car battery and what was the cost. I'm sure that it's LFP since li-ion wouldn't charge right from the alternator. Just which size and brand?
hi, i have started to make this with 32650 batteries. but i guess the outpot connector is the socket and the charging is to the terminals. is this right please.
hello my dear, take me out of a big doubt, nobreak battery is used to replace the electric bike ones???can i put 4 nobreak battery in the electric bike what happens?? to run a 6 coil alternator with a 350w 36 controller at 48 using 4 UPS battery? My battery is 7 Ah
Thanks for the great videos. I also build this battery bank, but my question is, can I connect two of this battery banks in parallel to get the double capacity?
The question I have in my mind is that you used 3s in one battery and 4s in the other, is there a purpose for this? Finally, my ups battery charging voltage is 16.20v 4s or 3s should I make a battery
There are two different battery chemistry one is lithium ion and other one is lithium iron phosphate. The cell voltage of the first one is 3.7V and the second one is 3.2V. For the second one we need 4S ( 3.2 x 4 ) to get around 12V.
Hi, I really liked your model. Just what I'm looking for. The only point is that I use catl prism batteries. If I asked you, would you be able to change the dimensions of the case and cover for me? I am far from 3D graphics, I can increase the size myself, but in this case, the dimensions for the screen and the connector also increase, and I need to leave them as they are, since I also use xt60 and the screen is the same size ... Thank you!
Is that the right connector for the pack? Surely it should be the socket, not the plug that goes on the live connections. Far too easy to short those connectors accidentally.

I've always wanted to build these batteries. Unfortunately, I only have 3 lithium ion batteries and I don't have the budget to buy more. I don't trust those cheap "1500mah" batteries from China. Ordered once and it was very light. Was actually planning to keep some money to buy the more expensive stuff to serve me longer during a power outage
Since the video is in the suggested ones. This will not work in a UPS. 30A is not enough for a UPS, the operating mode is not suitable, it is very expensive.
акум получился хороший единственная проблема это этот индикатор заряда. в общем индикатор надо соединять через кнопку иначе он высаживает акум в ноль, у меня там 2 банки умерло от переразряда
What you’re asking is correct, FePO4 is a less dangerous cathode material than other chemistries such as NMC. However, LiFePO4 batteries are still Lithium Ion batteries.
Nice project. A few remarks: The connector is better to use a female instead of a male. Less chance of accidentally short circuiting. Second, you're missing a fuse. You really need to fuse those otherwise they will explode. Thirdly, don't solder on the battery itself. It's difficult to heat up and it may damage the battery. Always solder on the nickel strip away from the battery. Also, be careful with your charger. Lead acid chargers are a lot different than lead-acid chargers.
This can be used only with ups where only smal amount of packs is used. It cant be used in high voltage battery systems like 8x12V. If one battery is depleted and BMS shut it down, then ohers wil reverse voltage on that battery and single BMS cant handle this and will burn,...
@@Okhe133 Yes yaar, but you're not maximizing usable range of the battery - lithium 18650 has a range from 3.8 when empty and 4.2 volts when charged: 3.8v x 3 cells = 10.8v 4.2v x 3 cells = 12.6v. This means your battery has a range from 10.8v to 12.6v. So when it's 100% charged you can call it 12v battery, but when it's 50% charged it will only have 10 or 11volts. You should use lithium iron phosphate (Lifepo4) 18650 battery in a 4s configuration for better 12v battery. They have charge range from 3.2v to 4v. This way minimum 12.8 volts and max is 16v.
The voltage difference between SLA and Lithium batteries is not insignificant, the BMS will NOT be able to mitigate this. This is NOT a safe hack and should NOT be used!
DISLIKE because while this works well with lifepo4, the title indicates this could also work with li-ion and this video does not discuss the issue of voltage difference between a standard ups that outputs up to 13+ volts into a li-ion. BMS could fail causing the battery to get over charged which is a fire hazard.
Oh, battery is the easy bit. You can't just put different chemistry batteries into UPS's and the like and expect them to work or last. You need to modify the UPS battery settings to have a hope, foolish to just swap and expect to work.
I would like to see some longevity tests on something like this. Some cheaper ups units will actively use the SLA battery to smooth out the output voltage, this might cause excessive wear on Lithium based batteries.
but would this be able to handle ac load for a bit? or would it kill the batteries faster?

What type of charger? Same as lead acid or constant current constant voltage?
U shouldn't cut the bms whires, it makes rsistance of each too be different.
Besids of that, tutorial is good, thx.
Thanks for the great videos.
I also build this battery bank, but my question is,
can I connect two of this battery banks in parallel to get the double capacity?
Certainly! Just need a larger container and appropriate BMS.
Does it really replace the Lead acid? Bcoz cut off voltage of lead acid circuits is different. Than full charge of li ion and lifepo4.
I have mentioned in the video description. But the Lifepo4 Battery cutoff voltage is very close to the lead acid battery.
@@opengreenenergy 12.7 for lead acid, 14.6 for lifepo4 🤔
Please go through this article regarding the charging voltage for the lead acid battery.

You can't call it a 12v battery if its 3s lithium and sits nominally at 10.8 volts. Good luck running any 12v devices besides a fan or a light bulb.
