battery shield for overclocked raspberry pi 4

Sat Mar 07, 2020 4:03 am

Hello

I recently bought this battery shiled V8 (https://www.aliexpress.com/item/3296969 ... b90afKVvhf), which promises to supply up to 3A. I use an overclocked raspberry pi 4 and I can't get past the 600Mhz range ... The raspberry is always showing low power.

Could someone indicate a good 18650 battery shield for the raspberry pi 4?

Note: I have already tested it with two Samsung 30q batteries and I was also unsuccessful

Where do you see 5v 3A listed? I see 3v 1A or 5v 2.2A

I also see it uses a regular usb cable between it and the Pi, what sort of cable are you using, can it handle the current without dropping the voltage?

Are your batteries genuine?

Hello

Thanks for the answer.

I bought the batteries as being genuine ...
I will test using another usb cable.
In the ad description it says it can support a maximum of 3A.

The keyword there is "maximum". I would typically not run any device at it maximum ratings.

It also goes on to say "not recommended for overload, easy to damage the module, speed up the service life), the output of current depends on the quality of the 18650 battery!"

All in all, given the source and the price I'd be happy if it delivered 1 amp properly.
