It will work for a very short time because the rated voltage of the UPS is between 12 and 14.5v. This battery can't even put out 13v.

Nice upgrade from lead battery to liion battery pack

[@umrashrf]

What about coolant to avoid overheating and fire?

[@PrithwirajBose]

That's not a wise idea to change the battery chemistry of an UPS without adjusting the controlling circuits. A 12V lead acid battery is meant to get fully charged at 14.2V (discrete) or 13.8V(Continuous). That's way too much for the 3C Lithium Ion Battery pack. You need max 12.6V. The BMS will protect the cells from overcharging to some extent, but you will surely never rip out the full lifespan of those cells. The low voltage cutoff of the UPS will trigger sooner than it should for the Lithium Ion battery pack and you will never be able to fully utilize the full charge of the pack (it can go as low as 11.1V but your UPS will likely cutoff at 11.7-12.3V leaving just 0.6-0.3V headroom for the batteries to operate (12.6V fully charged - 12.3V cutoff). And if there are charge indicators on the UPS, they will never turn green to indicate fully charged if the battery is replaced without circuit adjustment. So, such a battery replacement is not practical without carefully adjusting the charge/discharge circuits.

[@somdutttah]

Bro, very nice video. But I read in the comment section that you have modified the charging in the ups to charge the lithium battery pack properly. It would have been really awesome if you had explained it along with the battery pack making or made a new video cause it may be misleading for many of not pointed out that lead charging system is different from Lithium ion technology.

How did yours go

[@TheJay6621]

I have a question: charging a lead acid battery and charging a Li-Ion battery pack(12v) with BMS needs same voltage and current ?

[@tapendramandal]

we can't charge Li-ion battery pack with Lead acid battery charger so I had to modify the charging circuit of UPS so we can get appropriate charging voltage and current.

How I can charge 18650 battery can I charge them with module of powerbank ? With bms for security

[@GavinoBalisi-lk7xo]

very good work master

[@asa7398]

Instead of using normal batteries you could have used 5 amp li ion batteries which are also available yes they are 18650 and only 6 cells would have been needed to create 12v 10 amps battery pack and the ups is not made to charge li ion batteries let me tell you use a simple charger pcb and connect the 12v input of ups to the pcb circuit it will help to keep them safe along with the bms

no fuse on each cell means.. if one gets bad meaning short.. high current will flow from other batteries that are in parallel and we know how will it end in that case

[@sridharj9095]

Lithium ion batteries need a CC CV charger to fill their juice. Others may lead to an explosion. The way of handling 18650 lithium ion batteries is needed to be safe.

[@mangasingh3832]

[@hectormariscalramirez7511]

Ese no es problema. La ups solo permite de 350 a 500 ma para cargar la batería. El problema que yo veo es, 1, que el pack soporte la misma descarga que la batería de acido plomo. Y 2, que la ups maneja mucha temperatura por el trasformador, la cuál eventualmente llega a la bateria. Cuando se termina la carga de la batería de acido plomo con una PC , esos cables se sienten muy caliente(+ y -). Me da miedo que esa batería vaya a hacer explosión en algún momento por temperatura

[@AnxietyReliefYoga]

That's not the problem as your laptop and phone gets even much hotter than this during high operations. My main area of concern is that the pcb should have thermal cut out sensors or sensors that can be attached to the battery body from the pcb. Like we have a laptop and power bank batteries.

[@ErrorXTech]

Lead-acid batteries use the (CCCV) charging method. so ya can replace them with lithium batteries. plus the IC board is going to protect and maintain the cccv more accurately

[@johnoconnell5202]

Yeah, I will say, I don't understand exactly what the circuit they added does or how. But i do know messing with home made battery set ups, lead to lithium battery explosion and fires. I'm sure there are safe ways to do this, but...not being an expert, I can not tell if just adding the circuit makes it as safe as factory made batteries, that are made under approved factory safety standards. This maybe okay, but it also may not, so i personally wouldn't buy or make this.

[@AndreiZamyatin-Svetovid]

Не делайте так, логика работы контроллера бесперебойника не расщитана на контроль литиевой батареи и просто заменить свинцовую на лицевую черевато пожаром взрывом лития и никакой драйвер не поможет. Так литий не любит перезаряд, а в бесперебойника свинцовые постоянно под зарядом стоят. Так что как минимум бесперебойник должен контролировать батарею и при полном заряде отключать ее. А в случай отключения питания она должна подключаться. Так что с такими вещами можно без дома остаться.

[@edmarkota]

Есть грамотное решение этой проблемы в виде снижения конечного напряжения заряда до 12 Вольт. Причем именно до 12, а не 12,6, чтобы аккумуляторы не находились постоянно под максимальным напряжением. Я ставил литий в бесперебойник 1000ВА. Там используются 2 свинцовых аккумулятора, соединенных последовательно. Напряжение заряда по 3,9В на банку при использовании батареи из 7 секций по 4 банки. Полет нормальный. Встроена плата ВМС с контролем состояния по блютуз.

Lithium ion cells cant be charged like lead ones, max voltage is 12.6 for 3s and ur putting around 15v, it will burn the bms

[@rock10061984]

I tested 5 brands UPS crarge only 13.53~13.75V. The bms will cut charge when battery 12.6~12.9V. But UPS will stop output too early when battery still have energy but volter is low for Lead-Acid Battery.

[@lfmlokal-fernsehen9461]

[@opranjr]

Please do not let the UPS charge the Li-Ion 3S Battery. The 3S has a nominal voltage of 11.1V and a maximum of 12.6V (4.2V per cell row) - The UPS will attempt to charge the battery on the Pb voltage standard which is 14.4V. This will take the cells way over 4.2V and the BMS will probably burn its resistors as it will attempt to stop the current from passing, entering the "overvoltage" mode. If you don't do that, at least pin this comm so that people won't do it either. Thank you. Nice pack, btw. :D

You do not measure the charging voltage of this UPS. Very important to understand, that it is not over of 12.6V, otherway the overheat and explosion is only the time... I think, that You need to place another smart bms module with the termosensor and the different charging input and power output and the additional cc-cv module with the max voltage and current ajustable.
