Review Summary

This is one potential weak link in your AVX system. I find that the transmitter battery lasts a very long time, but the receiver ones not as much. Two of these get me through a day pretty easily though. I suppose that depends on what you're shooting though -- I'm commercial and there's usually a lot of time between takes.

This battery is small, light, and works well.The battery has lasts pretty well. Especially since the receiver turns on/off with phantom power. Charging is easy. The rubber cover can be a tiny bit fussy at times, but overall it works well. Overall, I would buy one again.

Works perfectly with the AVX system receivers. I get about 3 hours on a single charge. Build quality is average.
