@@andrewthuku2638 for a motorbike motor battery pack 72V 80 Ah you will need 72/3.6 =20 cells in series and 80/3.4 =23.529, say 24 cells in parallel. You can go with a 20S24P NCR18650 battery pack with a suitable BMS that can balance cells, overcharge/discharge, over temperature and short circuit protection.

@@andrewthuku2638 not that good in terms of capacity retention overtime. Cycles when DoD <= 80% original capacity is 200 times, as compared to other popular 18650s like Molicel P26A, which has a capacity retention of > 500 cycles

You have to look for chargers that support PD 2.0, 3.0 protocol for fast charging and voltage switching. A regular 5V 2A power supply will take 10 hours to fully charge, but a PD 3.0 with 45W will only take 3 hours lesser to charge :)

@@fardinahommad No, it doesn’t

Yup it’s one of the high-quality power bank builds you can find 😊

@@ruwanhasaranga4554 Yup, I’m using Ender 3 Pro in the video :) With the SKR Mini E3 it’s the same for Ender 3 pro!

@@tiendang6790 No unfortunately, Airlines typically only allow 100 Wh max power bank on flight. But this has 111 Wh, so it exceeds the limit

8 but one was hidden in the picture

@@cendlam Interesting question, yes you are right about the lower capacity but it has a higher nominal voltage of 15.36V, thus it has a high energy of 75 Wh. People do sometimes get confused with mAh and mWh. mAh is the amount of current a battery can provide in 1 hour. mWh is the energy a battery can provide in 1 hour. Energy that goes out to the power bank is the same as the energy that goes in to the laptop, taking away losses in conversion. The power bank nominal capacity is 30000 mAh, but it has a lower voltage of only 3.7V, thus its capacity in Watt hours is 111 Wh. Take 111 and divide by 75 you will get around 1.48 times of charging.

Yes you can. But when using laptop charging is slow because most uses only 65W Type-C

It’s not the power supply that is fault but probably the connection scheme of the motor. Most motors have an enable pin to turn on the motor. Usually there would be the instructions on how to operate the motor on the website, go figure 😊

@@AxomeV10 3 times due to conversion losses in the battery → USB → phone battery

Baseus Amblight is made of plastic case, whereas the USAMS 65W 30000 mAh is made of aluminium alloy casing, which is more durable. On the other hand, if you prefer to charge many devices simultaneously, the Amblight would be a better option as it has more output ports than the USAMS

@@striesDIY ok

@@papus9163 Glad you liked it 😁

@@awesomeboss4558 haha I do get that sometimes

Thanks for the suggestion! Definitely will keep that in mind :)

thanks for the suggestion! 😁

Format your sd card, download the firmware for ender 3 pro and transfer it to your micro sd. Name the file as firmware.bin and eject your card. Put the card into the motherboard’s slot and turn on your printer. That should work out

Still working great, meets its 18000 mAh @5V 3A rating

@@striesDIY thank you I will buy this

Assuming 80% efficiency of the 65W output, the real capacity is near the field of ~26700 mAh

Wow, that's dope! Anyway, are u still using that powerbank? Did the batteries capacity degrade? If so, how much? Sorry for asking too many question, im afraid of getting scammed😢😢@@striesDIY

No probs, charging time would take longer

The most accurate way is to directly measure the capacity of the lithium ion battery

But this power bank battery is very hard to remove, and also dangerous

You can connect it to a type c output charger

The metal sticking on top of the scope is usually a 1 kHz reference for the calibration

There are different variations actually

The siren shown here is a Hormann ECN-1200. It is considered a type of electronic outdoor warning siren.

You should, it’s a very good motherboard!

@striesDIY Bought and am installing it as I write this. Trying to figure out where to plug the bltouch.

Still working nicely :)

Generally I would advise renaming it to firmware.bin as it is normally standardised :) Thanks for your support!

Not really, I’m from Singapore

These sirens are used to warn people in times of emergency, since it is important that these sirens do function when they actually need, they regularly test the sirens every 1st day of the month at exactly 12:00 p.m. to make sure that they still work :)

Yeah, and it can be quite difficult to tell sometines
