| | | (...) Thanks for your replies. Both are RCX2 and I use the Robolab software. In Administrator / RCX settings you can set the RCX IR-power setting to high or low, but both were already in high. After some testing I found out that the main problem are (...) (18 years ago, 20-Jul-06, to lugnet.robotics)

| | | | (...) Depending on the kind of rechargeables you are using, they generally have significantly different characteristics. They also often output a slightly lower voltage (about 1.2 or 1.3v per cell as opposed to the expected 1.5). If you have a (...) (18 years ago, 20-Jul-06, to lugnet.robotics)

| | | | Hi Danny, (...) Have you seen real failures using some rechargeables batteries? I believe that the RCX motor driver IC is really foolproof, and I don't think anything could be destroyed using various kind of batteries (provided that the 9 or 10 (...)

| | | | (...) I have not seen them on the RCX, but I have on other devices, where power transisotrs have died. Its all to do (I think) with the characteristics under load, and the fact that larger spikes in current may occur with rechargeables. If the IC (...) (18 years ago, 21-Jul-06, to lugnet.robotics)

| | | | (...) Yes, the driver IC is current-limited to about 500mA (and thermal limited too), so it is very hard to destroy! (...) I have used NiMH batteries a lot on RCX, the only adverse effect I noticed is that the power available on motors is nearly (...) (18 years ago, 21-Jul-06, to lugnet.robotics)
