Jerry,
I really haven't timed how long a battery charge lasts on the Handyboard but I
did add a second 9.6v battery pack for the purpose of isolating the motor
power from the logic circuit power. I did this to eliminate motor RF
interference to the sensor readings. As a side effect my time between
recharges has increased. I had to cut the motor power trace and ad a jumper to
the expansion board to power the motors, expansion servos and lego ports. I
see no reason why you couldn't just add another 9.6v battery pack in parallel
to the original. In this way you would maintain the 9.6v input but effectively
double your ampere hour capacity and your time between recharges.

| I am currently using nickel hydride AA cells in two 4-cell battery boxes and so far during my construction and testing of the board they have not needed recharging yet. I didn't have access to a mains power supply most of the time, so after checking (...) (24 years ago, 19-Sep-00, to lugnet.robotics.handyboard)

| i'm not sure if wiring two nicad packs in parallel is a good idea. the packs would fight each other if either one's voltage varied even slightly from the other. i'd recommend either (1) John's initial suggestion of adding a separate pack solely for (...)

| Hi, Quick question. How much runtime are you getting with your Handyboard based robot? With sonar /IRPD pinging once per second and my sensor array being controlled by two servos and my Lego motors pushing the 6 wheel drive rover I am getting 2Hrs. (...)
