what kind a run times do you get from that? I just picked up the new RH1 MD and it doesnt have an external AA like my RH10 does and this thing would be pretty sweet for doing a long show.
This very cool kit seems to output up to 200 milliamperes at 5 volts. So some higher power devices (like Microtrack deck especially with internal battery still charging) are not going to work very well, and/or very long.
Suggest using highest capacity 2500+ma capacity NiMH AA cells over regular alkaline, or maybe try newer 'OXY' type alkaline from Sony or Panasonic for longest possible operating times.
I was going to put some Monster 2300mAh NIMH rechargables in there. perhaps I could find a lithium cell to put in there. Does a MT consume more juice then the MD does?
Quite a bit more; likely 2-4x more than MD.
Measured 6 C alkaline battery milliamperes power draw from external BC-MT power sled connected to Microtrack with and without the battery charging and posted the chart of the results at near bottom of page:
www.sonicstudios.com/mt2496rv.htmActual current going into Microtrack deck's 5 volt USB connection is more or less same as measured pack battery drain as BC-MT USB input. BC-MT internal switching voltage converter is 75-95% efficient depending on capacity remaining in the sled's 6 C cells.
Chart is based on near full capacity (9 volt max) sled batteries, and switching regulator is bucking 9 volts) down to needed 5 volts, so measured draw LESS than what deck is drawing by ~20-30%. So if chart says sled battery draw is 200 milliamperes, likely deck is needing ~300 milliamperes at 5 volts USB input to operate
If I made chart of sled battery draw when alkaline sled batteries were near end (4.8 volts; batteries at nearly half rated voltage), then converter is less efficient and slightly boosting battery voltage to needed 5 volts, and measured current would be higher than actual current draw of MT deck.
Bottom line is MT deck is going to draw at least ~225 milliamperes with already fully charged internal battery (minimum current draw for deck to operate), so 2 AA cell boost converter kit seems not a good fit.
