Hello,

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

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

[http://www.conrad.com/100-240-V-/-Ac-Fa … 162/md5%7D](http://www.conrad.com/100-240-V-/-Ac-Fast-Charger-1a-Led.htm?websale7=conrad-int&pi=237739&ci=SHOP_AREA_21100_0502145&Ctx=%7Bver/7/ver%7D%7Bst/3ec/st%7D%7Bcmd/0/cmd%7D%7Bm/websale/m%7D%7Bs/conrad-int/s%7D%7Bl/int/l%7D%7Bsf/%3Cs1%3E237739+-+62+%3C/s1%3E/sf%7D%7Bp1/6bc7c5454f771d426586c22601885f95/p1%7D%7Bmd5/30b8a0697e0fca2822b43104b8363162/md5%7D)

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
