Guitar amp powered by rechargeables?

Batteries and Chargers Rechargeable Batteries

I know this is a little off topic, but does anyone here know of a small guitar amplifier that is powered by a rechargeable like a 18650 or a 26650?

I’m not aware of any that use Li-ion but the Roland Micro cube GX runs on 6xAA rechargeable Ni-MH (9v) or Alkalines

Specs from Roland:
Alkaline battery: Approximately 20 hours
Rechargeable Ni-MH battery: Approximately 25 hours (When using batteries having a capacity of 2,400 mAh.)

I’m pretty sure you can get AA Ni-MH with a higher capacity than 2,400 mAh.

I have the Micro Cube, mine is older and also runs on 6xAA, It’s a pretty cool little amp with a big sound, effects and modeling. I haven’t tried it myself yet but users have reported it will run up to 25 Hrs. on Ni-MH which would be 7.2v

With that in mind I would assume you could easily convert it two 18650 or 26650 in series to get 7.4 - 8.4v, a bit higher than the 6 Ni-MH and not over the 9v of the 6 AA. You’d just need a 2 cell 18650 or 26650 series battery holder and wire it in.

I’m not positive but maybe you could just wire the holder to a plug that’s the same as the AC power power plug, since the AC power cord is a 9VDC transformer type power supply.

But personally I think I’d be happy just using the Ni-MH.

Roland also has several other battery powered Cube series amps:
The Micro Cube RX the Mobile Cube and the Cube Street (all three are 9v / 6xAA)
And also the slightly larger Cube Street EX (12v / 8xAA)

The Yamaha THR series is another series of battery powered mini amps that also run on rechargeable Ni-MH (or AA alkalines)

I’ve been considering one of those, I demo’d several versions at Guitar Center and they were really awesome.

Specs from Yamaha:
AA alkaline batteries (approx. 6 hours)
or
Nickel-hydride batteries (approx. 7 hours)

there is one by crate that uses a 12v 7ah sla.
i get them in for repair.which is just battery replacement.
your best bet is to find something that runs from 3 alks and install a holder for a 18650/26650.

i have a small marshall micro amp that’s powered by a 9v battery, i tried it on 2x li-ion batteries in series and it worked fine!
