Is the circuit applicable for Maximum Battery voltage (volts) indicator Or circuit modification is required?

Thanks & Regards,
Prashant S Akerkar

The circuit shown above? If so, it's so small, can't distinguish what's being shown

Thanks.

Great breakdown, loved the video

Thanks.

Can we modify the battery level indicator circuit with IC LM3914 or equivalent IC to be used with Uninterrupted power supply batteries?

Thanks & Regards,
Prashant S Akerkar

I don't understand what you mean by that...

Thank you.

I mean the Battery level indicator circuit to be designed for connecting to the UPS batteries for displaying the % level used by the UPS Batteries in LED display.

Can we use IC LM3914 or any other equivalent IC for the above requirements?

Thanks & Regards,
Prashant S Akerkar
