min safe voltage for an original cypres?

[ljwobker 2]

Friend of mine is getting back into the sport after a couple years off. When powering up the cypres, it pauses at 6140' -- which as I recall is somewhat low for the battery power.

I can't remember if it's "too low" or not, though.

On the cypres website all the manuals are for the Cypres2... anyone happen to know what value is "too low" for an original cypres?

5700?

Regardless, the self test will fail if the voltage is too low.

Agreed the self-test will fail if the voltage is too low to fire the cutter/save your life.

I have seen Cypres 1 succeed in turning themselves on with battery voltages in the 5800 range.
Much below that and batteries will only last a few more weeks or a few more dozen jumps, because batteries discharge rapidly when voltage drops below 6000.

CYPRES 1 batteries must be replaced after 2 years, regardless of voltage.

The manual says it will stop for 3 sec. between 6500 and 5700 which means 6.5 to 5.7 volts. If the battery is to low to activate the cutter it will show error code 8999 or 8998.
