I have encountered problems with Phottix BP-D80 with my D90.
Just wanted to check if anybody experience the same problem.
I put the Original Nikon battery 7.4V @ 1500mAh and a 3rd party battery 7.4V @ 2800mAh together.
When my 2800mAh battery drained out, my camera cannot turn on even my 1500mAh battery still got full charge.
Is it my battery grip or its the battery dissimilarities?
send me a message.
