Sennheiser BA 20 Reviews
Always have a backup battery
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. Tip: luckily I temporarily saved the problem by connecting the damaged battery to a power bank and it worked while it was connected. The same day I ordered two of these products,
AVX is the way to go!
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.
Always good to have a back up
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.
Always have an extra charged battery on hand.....
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.
I guess it was about time.
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.
Limited by the size of the receiver, run-times are much shorter than the transmitters you'll be using. Spare BA 20 packs are a must on any shoot.
Original battery. Great capacity and works as it should.
