I've had mine tied to a power supply for a while now and no adverse effects, It is a regulated supply though and I'm meticulous about checking the voltage before powering up.

I've also modded the charger connection so that I can charge the battery in-situ when its turned off or run off power supply. Too idle to mess with those fiddly little clips.

Your concerns tie in with my own, 9 cells at 1.2V is fine but when they are freshly re-charged they can put out as much as 1.4V This would give 12.6V which is over the recommended level for the RCB.

It might explain why they didn't go with a 12V system which would have been more standard.

Either that or they couldn't be bothered to redesign the front cover to get an extra cell in.....

Hi, I have plenty of 12V power supplies, my worry is that most "12V" supplies actually pump out around 13-14v, would someone who has sucessfully used one of these mind check ing the no load output voltage for me?

Mine is 13.8V

Many thanks

I will then continue the hookup of a PC ATX power supply. Thanks, you adventurous soul. NO SMOKE is good!

I have my manoi hooked up to 12v, and I am not seeign any issues. No smoke looks good. I wired up a teather to a 12v dc 1.25 amp wall wart.

AHA! 12V. I will try it. I have a brand new ATX supply that I prepared before and stopped when I got concerned in favor of a regulated that I could control... Will post the results or smoke.

Taking a cue from slashsplat, I think I am going to go the route of using a power supply.

In looking over the RCB3-J english documentation, it says in the specs that the operating volatage is 9-12 volts. I just wanted to see if anyone else has hooked up 12 to the RCB controller. 12 V power supplies are all over the place and cheap.

Also there is a shunt on Power Supply Setup on the controller board. Does anyone know what this does?
