I'm trying to use this MX-LMount battery sled on the MixPre-10 II and getting flashing red ring LEDs on all tracks when powering it on, with either a pair of fully charged genuine Sony NP-F970 batteries attached, or a pair of fully charged genuine Sony NP-F570 batteries attached. MixPre-10 II already has L-Mount selected as battery type in the MixPre-10 II's power menu. No other batteries/power sources are connected. I'm using an approved SD card that has been formatted in the MixPre-10 II. Any idea what could be causing this issue?
We're glad you were able to resolve the issue.

question
Hi, I was curious what size/capacity of L-mount batteries this sled can accommodate? The photo here looks like it can use the larger/higher capacity batts, but the image of this sled on the Sound Devices site uses the smaller, lower capacity batts. Any observations? Many thanks!
Larger is fine, but the smaller make for a great form factor. Even the smaller tho when sitting flat on the table will prop the back up on an angle slightly.

question
Do you have to use two batteries at once or can you use one? Also, what's the estimated run time with phantom for the smaller (2900mh) and medium (5000mh) Sony NPF batteries? Thanks.
You only need one battery. I use two just because it seems a bit less awkward to handle. Two of the smaller batteries will run the recorder and a couple of mics all day long.
