You need to check before all cell capacity for best backup

Davon hab ich zwischen Frühling und Herbst 20 Akkus mit je 14Ah gebastelt. 280Ah bzw 3500Wh. Gespeist mit 180W Solarpanel und hat nen 400W sinus Wechselrichter bekommen. Noch just for fun. Bisher nur die Weihnachsbeleuchtung dran angeschlossen

Nice project 👍

[@TechnicalJugaad-k9]

Good

[@electronicsandinventions5919]

Thank you!

[@Lakshmanasamy-p9y]

I have 12 laptop lithium ion battery it to make 12 volt battery package how many mah please tell me bro

[@updatedalways6241]

8ah

[@electronicsandinventions5919]

It depends on each battery and the rating mentioned from the manufacturers

[@Lakshmanasamy-p9y]

Bro laptop single lithium ion battery how many mah
Or it differ about company please tell me bro😅

[@electronicsandinventions5919]

The capacity of laptop batteries varies, depending on the manufacturer and model. You can check the label of each cell, or you can use lithium batteries tester to check the capacity and the current of each cell

@electronicsandinventions5919 bro iam student so iwas low money budget so i dontnot buy a lithium battery capacity checker 👍

[@Lakshmanasamy-p9y]

@electronicsandinventions5919 bro i have a three type of laptop battery to make battey pack any problem because laptop battery capacity mey differ so please clear my doubt bro

[@electronicsandinventions5919]

No problem, but you will be limited to the lower battery capacity

[@eshlavathnithin5459]

How to recharge that battery

[@electronicsandinventions5919]

Connect the outputd -ve & +ve to any DC charger 12+ ~ 14.3V
The output acts also as an input for changing

Из ноутбуков хорошие аккумуляторы это только Panasonic NCR 18650b

[@electronicsandinventions5919]

Thanks for the note

[@TheAalihero]

How many ampere in there?

[@electronicsandinventions5919]

Depending on the amps of each cell, in this project, we have 7 cells in parallel and then 3 sets in series.
Asumming all cells have the same current in this case You shall multiply the amps of one cell by 7 to get the total amps. Depending also on the BMS internal board
If each cell can provide 3000 mAh
3000×7=21000mAh= 21Ah

[@suryapatnaik5720]

Can you send me some, I'll pay for delivery.

[@electronicsandinventions5919]

Apologies, I didn't sell batteries. You can check with your local laptop repair shops

[@robotronik2371]

How much ampere one batterie can flow?

[@electronicsandinventions5919]

Original capacity may have been 1800-3600 mAh per cell.
After heavy use, the capacity often drops to 1000-2000 mAh, and in some cases, even lower.
