I strongly recommend always having a backup battery. Mine all of a sudden stopped charging and I found out the night before filming a video.

Smaller battery but still packs a punch. I would at least have 2 of these per lavalier set and you will be good to go for a day or so depending on your production.

Purchased this because my original battery doesn't show a green charge light while charging. Got me a little scared so I picked up another one just in case.

Whether you need it or not, an extra charged battery is recommended. So, suggest you purchase a backup BA 20 rechargeable battery pack for your transmitter and the BA 30 for your receiver.

We have had our AVX wireless packages for almost 2 years. They have been great. Considering that the wireless units they replaced cost 8 times more.� But now we thought it was about time to purchase backup battery packs. I expect they will be just as good as the first.
