Just grabbed a Traxxas Summit 1:10 from ebay, it came with 4 batteris Traxxes 8.4V 3000mah.
I normally fly Planes with LiPos, my LiPo Charger has a NiMh Programm as well. I know from lipo: a cell is 3.7v regular and 4.2v full - therefore a 2s Lipo 7.4v full shows 8.4v
But I am a bit confused:
My 8.4v NiMh battery has 7 cells each 1.2v, summing up 3000mAh
On my multimeter I read 9.16v on one battery and 8.5v on another battery.
I took the 9.16v battery, hooked it up to the charger, chose the NiMh Programm, being conservative I chose only 1.5A charging and push GO. The charger starts pumping a bit and after 10 Minutes, it stops and the battery says 8.5v.
An empty NiMh cell is 1.2v equals 8.4v on my 7 cell setup.
A full NiMh cell is about 1.4v so it's 9.8v
For charging a 3000 mAh battery I should be allowed to chose 3.0A for charging and it should take about 1h t ofully charge.
Where am I wrong?
