Sodium Battery with Voltage Display

Congrats on 200K Subs!! 😃🥳👏 🎆🎉🎊🎈🎈👍🤩

[@JulianIlett]

Thank you!!

Another option for lighting are strips of series LEDs and a TV backlight driver board (few quid off Aliex) that takes a low volt dc input. Basically a dc-dc converter with high voltage constant current output.

Good Morning, Julian!! From New England. 😃🔋🔋🎥

Depends on the type of led, normal old school or phosphor as the will have a forward voltage. So its resistor = (supply voltage - LedVf )/required current.

What camera are you using these days Julian? Focus is really soft and the colour is very washed out. I thought my glasses were mucky to begin with.

He may need to clean his lens. Reminds me of taking a photo with my phone and it's got some oil on it

[@JulianIlett]

The lens was a bit dusty, so image quality may improve now :) Cheers.

Ya last I remember he was using an old or even current cell phone

24:32 "LEDs under that Yellow Jelly type substance" Does anyone know where you can buy that Phosphor coating please? I've seen it applied to blue LED Chips in manufacturing of White LEDs But I have no idea where to buy it from. In a syringe for example.

Really enjoyable. Wish my channel was half as good. 👍😁

[@adriaankoffiekar6442]

Kan je wat meer info over de gebruikte Sodium cellen geven? Evt. Een link? Groet, Adriaan

[@Sopheris]

Do you think tk15 coulometer is best choice for ebike? Im about to buy one and cant decide.

[@frankowalker4662]

To mount those balancers, could you solder a couple of earthing lugs to the PCB somewhere and use them as mounting holes ?

[@williambunch1365]

Where did you get the lights?

[@mickre-fuses]

I think the LS76920 could be a clone of this: TI 'BQ76920' 3 to 5-Series Cell Li-Ion and Li-Phosphate Battery Monitor (bq76940 Family)

[@JulianIlett]

Yeah, that could be it :)

[@jlucasound]

Those resistor values _are_ crazy! Wow! A difference of 900K Ohms, and both in the "stratosphere" to begin with! Do you have a 904 resistor you can add to the 104 to see if the 4S LEDs get as bright as the 5S ones? 🤣😂💡🪔
