Wondering if anyone has used the following batteries in a 2b? If so do they work ok? https://www.amazon.co.uk/Rechargeable-P ... 381&sr=8-3
Thanks, Lee.

Didn't try one of those with the 2B, but a friend of mine tried an usb rechargable pp3 battery in a guitar pedal, and it interfered with the signal (and I see some reviews on the amazon page that state the same). Interference in the sound of a guitar amp is no big deal, but I would'nt try interference in the electric signal sent to my genitals

looking at the spec....... noooooo!!!!!

Si

Always better to use the mains adapter or an external 12v battery. The 2B literally jumps to life when running on 12 volts!

Yeah, I did. I found them to be relatively low in power than a standard battery. As mentioned before, the mains power supply is best

Question to Admin
Why are the Lithium rechargeable batteries a problem?
I see they supply a slightly lower voltage and may not deliver as much power but is that a problem unless trying to max out the power?

I suspect it is a 3.7v nominal cell internally and a boost circuit to output the 9v and the output is not perfectly smooth DC like you would get direct from a battery.
