spotify95 Thank You! I was pretty sure but I think you nailed it. You know your stuff! I think Kenh did an awesome job with neatness and making a safe and dependable unit. I would think a buck/boost converter would be a must if your load is sensitive to voltage being within a close tolerance. I would have replied to your post directly but RU-vid seems to have disallowed that. Maybe I made a mean reply to an idiot and they are spanking me. I did not realize one could get a case that matches the lead acid dimensions. Interesting.
Nice way to repurpose a 12V lead acid battery. Having said that, you can quite often find kits online comprising of a battery casing (similar in size to these lead acid batteries), and a set of battery holders, which basically allows you to create your own 12V Li-Ion battery pack, thereby saving the need to open a lead acid battery. These are ideal for powering portable electronics - though bear in mind that it won't be a full 12V output, as it is nominal 11.1V (and minimum 7.5V - 9.0V, maximum 12.6V). So you might want a buck/boost converter if the output voltage is critical.
Ya he visto varios vídeos como este y me preguntó si es mejor estás baterías de litio por qué no comercializan baterías del tamaño de las de plomo en litio?
La seule chose, et je suis sûr que tout le monde est d'accord avec moi, ce sont les possibilités de fabrication d'une batterie. Cela nécessite le moins d'équipement dont vous disposez pour fabriquer un avion. Il suffit de simplifier les choses et de rendre le travail presque manuel et très simple.
Also, just realized: The Lithium Ion battery is 14,000mAh capacity, not 15,000 (each cell is rated 2,000mAh) The battery pack is not designed for 100A discharge current. The protection PCB may be rated at 100A but the cells are rated at 2A discharge current each - 14A total. Trying to draw 100A from that battery pack will make it very unhappy, very quickly.
@@grzegorzbetyna4307 Cześć kolego ha no oczywiście że nie tylko ty oglądasz jego filmy. Miło mi cię to słyszeć. Tak w ogóle to się okazuje że wielu twórców jest z Polski pomimo tego że nie piszą nic po polsku. Ciekawe jak jest w tym przypadku
Using 14 AWG wire is insufficient for a current of 100A; instead, 10 or 8 AWG wire should be employed. Additionally, terminal connectors should be crimped with the appropriate tool rather than relying solely on soldering. It's crucial that the connectors are curved so that the metals can embed into the wires. This ensures that if the cable heats up, the expansion won't cause the metals to loosen from the wires, as solder alone may not provide sufficient support. By curving the connectors, any expansion will facilitate a deeper embedding into the wires, thus enhancing their contact.
😉 *Muchas gracias amigo* _quedo muy buena esta batería de litio_ por cierto me gustaría que pudieras mostrar el consumo de amperes del motor DC. Sigue con más transformaciones de baterías de plomo a litio, me gustaría una gran de de autos. Saludos 🖐️😎
You can't use a lead acid charger on these re made batteries because they can charge up to 13.8 v for sla battery chargers and 14.4 for liquid lead acid chargers. Can't use them in a gas scooter as starter battery or in an emergency light, the chargers are incompatible. You need a proper li-ion 12.6 v charger. Need to put a warning label on those packs!
@@DavidSmith-dm8ew i mean i use my lifepo4 in my ups regularly and the overvoltage protetion has been working..but i guess its a good idea to not rely on them
@@Iinustechtips Lifepo4 are different then li-ion. You can charge the lifepo4 (4 cells 3.6v = 14.4v) with ought any issues. Dumping 14.4 into 12.6 li-ion is a problem lol.
The issue with using a 3S Lithium-Ion configuration is that the nominal voltage is just about 11.0 V. Most devices you might use this in will cutout by 11 V or even higher. This means that you can only use half of the available capacity, or about 7 Amps, which is what you started with. Of course you could use full capacity if you connected the battery to a Boost converter then out to the device.
I was thinking the same thing. also you can't use a lead acid charger on these re made batteries because they can charge up to 13.8 v for sla battery chargers and 14.4 for liquid lead acid chargers. Can't use them in a gas scooter as starter battery or in an emergency light, the chargers are incompatible. You need a proper li-ion 12.6 v charger. Need to put a warning label on those packs!
@@DavidSmith-dm8ew That's why bms is used .it controles the charging and discharging processes off the batterie ,when the maximum voltage is reached when charging the batterie or the minimum voltage is reached when using it ,the bms turns off the batterie You can charge this batterie with lead acid charger without any problem
@@Ahmed-Youcef1959 Don't ever rely on the bms when you are using an in compatible charger, that's a great way to burn your house down, burn up whatever you have the battery in. This is just bad information to be giving out. This is why they make specific battery chargers for Li-ion, otherwise everyone would be sticking all kinds of voltages on lithium batteries. Remember they need cv/cc chargers. A lead acid charger is not a cv/cc charger.
I have been using the other 12 volt 3S 40A BMS boards but the voltage always reads lower than the battery pack so I just ordered this BMS because it’s balanced and hopefully this one turns out better than those cheaper 12 V 3S BMS boards. I’m going to follow how you soldered it. Btw that pinky nail being longer than all other nails lol I think I know why.
Yeah I got balancing issues with my pack even though the bms got balancing resistors, I fully charged every cells to 4.2V and assembled the pack but after discharging and charging it the pack voltage stays at 4.2V, 4.0V, 4.0V, what to do?
Good morning Sir. Can you explain to me how the 100 A results? How much mah is each battery? because even if it were 3000 mah, you would have 63A in total.
I tried the same but got one problem, my ups works normally on this battery if its already on and give backup after power cut, but if there is already power cut from grid then i can not start the ups iven if battery is fully charged. I need grid power to wakeup the ups I dont understand this problem help me
Hello and nice video 👍 i try made it this batteries with more capacity 18650 battery high quality 19800mah 3.7v 18650 batteries li-ion rechargeable battery ... Its ok i go if i made it that battery ??!!
