| | Using 10V gel-cell
|
|
Hi, Can anyone tell me if I can use a 10V gel-cell battery rather than the 9.6V NiCad pack? I don't think the higher voltage should affect the board - it's just a little more work for the regulators. But what about the charging circuitry? Will the (...) (28 years ago, 15-Nov-96, to lugnet.robotics.handyboard)

| | Re: U14 problem
|
|
Firstly, 19.9v is a normal unloaded voltage from a 12v DC adapter. The reason: these common wall adapters are unregulated, and voltage output varies inversely to current. I.e., if there is no load, the voltage is higher than the rated voltage; if (...) (28 years ago, 15-Nov-96, to lugnet.robotics.handyboard)
