The Sound Devices MX-LM1 is a compact, L-Mount Battery Sled designed to power your MixPre series devices reliably.
You can enjoy a hassle-free operation as it effortlessly slides onto your MixPre Original, MixPre-M, and MixPre II Series devices and can be equally easily detached with its integrated release tab.
However, remember to have a flat-blade screwdriver if you're using the MixPre-10 II.
