Battery charger for 3pi

Hello,

I am looking for a battery charger for my new 3pi.

I was thinking about this one (please click on “details”):

The charging current can be set to 0.5 or 1A (no values in-between).

It uses delta-peak disconnection.

I think both current settings should work with my NiMhm AAA batteries (900mAh), right?

Can the electrical connections (i.e. copper lines) on the 3pi PCB also handle a current of 1A?

What maximum charge current would you recommend?

Is it possible to use and program the 3pi while the charger is connected and charging?

Thanks!

Best regards,

Josef
