I'd get
http://www.hobbypartz.com/thac6smbachw.html it charges all battery chemistries, and has free shipping
Or if you are sure you are only going to use NiMh
http://www3.towerhobbies.com/cgi-bin...&I=LXTSA4&P=ML is a good charger
Don't take this the wrong way BUT that charger you have looks pretty crappy. I looked up it says compatible with NiMh...
SPECS: Pack Rating Charge Time in Minutes:
1300 to 1500mAh: 15 - 23 minutes
1700 to 2000mAh: 28 - 33 minutes approx.
so for a 5000 NiMh you would have to reset that thing around 5-6 times...
