Has anyone seen or used this new battery monitor device called the BVM-8s? It showed up on ebay this week.

My Cellogs have both of those features.Hyena said:The interface is identical to the cell log but has the added benefit of being able to specify the LVC alarm voltage. It also has a max delta V alarm, so if cells get out of balance by more than say 200mv then the alarm will trip too, which is kind of a cool feature.

Nope, but putting a small switch in the first negative wire would turn the device off.toft said:Thanks for report.
Is there some kind of swich on/off?
I'll check tonightWhat is minimum alarm Voltage? (thinking of using with lifepo cells).
They're the cheaper ones, bought 6 months ago. Are you absolutely sure yours doesn't have them?Hyena said:Really ? Is it the USB version or the cheaper version ?
Mine is the cheaper version but it's a year or so old, maybe they revised them more recently ?
I'll have to buy another one to check.
Not sure, my cell log only has an alarm output option of a normally open or normally closed - I've never actually used it. The BVM looks like it just outputs a voltage on the alarm line. When you plug in the external buzzer it also uses that for the keypress beeps - which are much louder than the internal beeper in the unit.dumbass said:Does it indicate the max capasity (volts and MA) of the external alarm? I'm assuming it's like the CellLog8 and can handle a small relay.
Pretty sure, I'll check again tonight.bobale said:They're the cheaper ones, bought 6 months ago. Are you absolutely sure yours doesn't have them?
