VOK power 1500 2s Lipo

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 ..

VOK1500 2s Lipo Battery Test (3 min 50 sec)

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 ? )
