Can I run the Aeotec Multisensor 6 on rechargeable Li-Ion cells?

Configuration Z-Wave
1

Hi,

not really a config question…
I’m running my Multisensor 6 on batteries, CR123 lithium cells to be specific.
As it eats batteries like candy, I’m wondering if I could use rechargeable 16340 Li-Ion batteries instead.
They would physically fit, but the Li-Ion cells are rated at about 3.7V while the lithium batteries are rated at 3V.
I’m concerned that the higher voltage would damage the device.
On the other hand, I couldn’t find any specific battery recommendation in the sensor manual.

Does anyone have any experience with that?

TIA,
Sebastian

The Li ion is getting close to 25% increase in voltage over the cr123, which may not kill the sensor outright, but might shorten its life.

A better option might be to power a 3v regulator with the Li ion and then route the output of the regulator to the sensor.

You should be able to find something on eBay for less than 10 dollars

I’m not sure if the sensor already has a voltage regulator that would allow it to work with a wider range of voltages.
Apparently it is already designed to work with only a single 3V cell, 5V USB power and 2x3V cells.

I’ve sent an email to Aeotec support - let’s see what they are advising.

Got a response from Aeotec: 3.7V cells cannot be used.
I’ve also found some 3.0V rechargeable cells from UltraFire, maybe I’ll try those - or I switch over to mains power.

If you switch to USB power, you’ll need to exclude (Remove Node) and then re-include. If you don’t, the sensor will act as if it’s still on battery power (slower updates, etc).

Yeah, I was aware of that. Thanks for reminding me!
