Do you use a 12V AC Power Adapter (to bjorn stenberg) ...............becomes
the unit very hot when the batteries is recharging or......?
When the batteries are fully recharged....the rockbox then turns off the
charging process on the recorder, is that true, and
the unit will becomes cooler or ........if deep discharge is on?
If (to all except bjorn:) you read the manual of the circuit that controlles
the recharging process (on the FM recorder), you can se there that the
recharging never stops, just ease off a little bit to, not to strong
charge....i think that if you gonna have a FM recorder and protect the
batteries you should have a timer connected to the AC.....that shut off the
recharging process after a few hours, not let it recharge the whole
night......thats my opinion (as another guy here wrote)
I have now bought a recorder due to the batteries is ni-mh and that the
recharing process is done by the software (rockbox:), really need the deep
2200 mAh and 4,2V should soon be passed by the ni-mh
batteries........already here in sweden it is very easy to get hold of a
1800 mAh .....obviously the unit will then be on 4,8 V

are a *huge* win over priprietary batteries due to competition between
battery manufacturers resulting in lower cost and ever increasing battery
capacity. Note that with modern batteries, the "regular" recorders outlast
the FM units with several hours.
