Has any one here replaced the battery on this amp. Having a difficult time finding a replacement that will fit in the case. Looking for some help here. Thanks

I'm also looking for a battery upgrade that will last longer because the sound of this bear is so wonderful that I need it to last longer or find a way to power it off the wall.

A battery like this one will work if you're able to strip one end of the supplied male-to-male power cable of its' connector, then solder that end to the B4-X's PCB where the existing battery plugs in using a PC motherboard-style connector, or simply terminate the power cable with a similar connector. Both methods may involve running the amp with the cover off.

Otherwise you could simply purchase two B4-X's and charge both, swapping the batteries (or even amps) when one is depleted. I haven't been able to find an off-the-shelf replacement for the B4X's battery with the correct motherboard-style connector, and there isn't room to fit a larger battery inside the existing case.
