1. Sennheiser BA 62 Qad Battery Charger
Light, small and versatile, our quad charger for Sennheiser BA 62 batteries (for SK 6212 digital transmitter) is powered either by a DC source (12 to 24V, a battery pack or an AC/DC adapter) either by AC (110 or 220Vac). AC power has right of way.
BA 62 batteries are High Voltage kind: charging voltage is 4.35V, whereas it is 4.20V for regular LiPo batteries. This extra energy allows for SK 6212 transmitter to run for 10h uninterrupted. Charge current is 1A.
A bicoloured Led monitors charge status: red, charging; green, charge terminated.
Dimensions (LxWxH): 4.45" x 2.20" x 3.15".
Weight: 10.23 oz.
2. Shure SB910M Qad Battery Charger
We designed this quad charger for Shure SB910M batteries, which power the ADX1M body pack transmitter.
As a basis, we used the formerly designed Sennheiser BA 62 batteries quad charger. Because of shortage, we chose an older chip, on stock and still very efficient: SB910M is a classic LiPo battery, and its charge voltage is a regular 4.2V (whereas it’s 4.35V for a BA 62 battery). Charge current is 0.83A.
Our friend Yves-Marie Omnes redesigned the lid, but the fundamental remains the same: the quad charger is either DC powered (by a 9 to 24 Vdc battery or AC/DC adapter), either by AC mains directly (110 to 220Vac).
Dimensions (LxWxH): 4.45" x 2.20" x 2.95".
Weight: 8.8 oz.
Both chargers are available for rental and for sale from DC Audiovisuel.
