In a nutshell
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).
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: 4.53’’ x 2.24’’ x 2.56’’.
Weight: 8.8 oz.
Grey prototype pictures, production case is black.
