I ordered a 2s 1500mAh battery for my WLtoys 12428 Crawler ..
It got here at last the other day .. ( Now I can have twice as much fun )
I never use a battery untested :
So here goes ,
I charged the battery @ 0.5 amp till it was fully charged .
I then discharged it to check capacity as well as how well the cells were matched ..
Discharging to 6v @ 0.5 amp one cell was 3.5v and the other cell was 2.5v .. ( not a good showing )
Recharged the battery @ 0.5 amp till its fully charged
Then discharged once again @ 0.5 amp to see at what point the imbalance kicked in
All was good till about 3.66v ( individual cell voltage )
By the time one cell was 3.63v the other was 3.53v .. ( 1120 mAh discharged )
I stopped the discharge right there and then , and went back to charging the battery @ 0.5 amp ...
I did not cycle the battery again ..
But rather went to bed , and then threw the battery in my WLtoys 12428 Crawler buggy ..
The video shows my running the VOK 2s in the WLtoys , and then checking the battery after depleting it ..
Cells were about 3.222v and 3.183v ...
Currently charging the battery @ 0.4 amp ( balance charging - Is there any other way ? )
