M 248 w external battery
ccage:
took the combo out for a spin for NMA last Saturday...ran the ext battery for 3 1/2 hrs and it showed 75% charge left.
Ran the mk4's w/ gain knobs on pre at about 60%...sounds great as usual.
Will see if the drain rate increases more or holds steady with what's left on external.

The 148 has 48 volts of internal batteries and no DC - DC converter. You would need to hook it up to a 48 volt external battery.

I'm convinced Doug built the 148 around a 48 volt power supply he had lying around

Doug is looking at external option for my 148 I sent him.
Will keep folks posted.
