Thanks for the detailed explanation John.
I have never had an issue with the Digifire 7 actually cutting out as I always carry spare batteries and simply replace it when the low voltage light cuts in. Of course I am not running Go To so my power usage is lower.
Kendrick have an interesting discussion of the reasons why they implemented this feature on the their website ( see
http://www.kendrickastro.com/lvc.html ) which makes the reasons clear. Whether this is valid, I am not qualified to argue having just about zero knowledge of electronics.
Obviously whether this feature is seen by the OP as a positive or negative point in their circumstances would have to be left to them.
