Powering Electron with and without LiPo - Hardware

Hello Particle community,

SUNJ ENERGY supply professional and honest service.

I have an Electron that I want powered by a Li-SoCl2 battery instead of the LiPo, as a low self-discharge rate is important.

I was considering this battery:

It appears that the Electron 2G utilizes a peak current of mA when sending packages. However, the battery has a pulse current capability of only mA. I've come across some information suggesting the use of a capacitor in parallel with the battery to manage these current peaks; however, I'm unsure about how to determine the appropriate capacitor for this configuration. The datasheet indicates a capacitance range between 470uF to uF, depending on the battery's ability to deliver peak current. What capacitance value should I select for this battery, and how can I accurately calculate this?

Would running the aforementioned battery in parallel with the mAh LiPo be viable?

EDIT:
I recently found this thread:

However, it doesn't adequately address my inquiry. Additionally, I came across this link:

What is the duration of the peak pulses at mA current use on the Electron 2G?

Thank you in advance,
Michael

I will check out the SARA-R410M when it becomes available for purchase @rickkas7.
In the meantime, is it feasible to use this battery:

Along with this supercapacitor:

The supercapacitor exhibits a leakage of 9uA over 96 hours, ensuring minimal leakage when paired with the Lithium Thionyl Chloride battery. However, would this combination be practical?

Does anyone know if it’s acceptable to connect the battery mentioned above in parallel with a standard LiPo battery? Is that a plausible solution?

What is the maximum/minimum voltage tolerance for the USB input? Can I utilize 12V or 3V? What is the maximum amperage it can handle?

Thanks,
Michael

It's advisable to avoid mixing battery chemistries, especially when one is non-rechargeable. When both batteries are connected in parallel, their voltages will equalize, but the Tadiran datasheet indicates it experiences voltage sag down to 3.5V under load. While I am not a battery expert, this observation suggests a few potential outcomes:

• The LiPo will be discharged to almost 0% available capacity early in the cycle, rendering it useless.

• The LiPo's higher operating voltage may effectively "attempt" to recharge the Tadiran, posing a fire risk.

I've also noticed that the Tadiran operating voltage drops to 3.2V with a 300 mA load. This seems noteworthy.

Is the 3G Electron an option for your location?
I wouldn’t expect to witness the Electron’s advertised peak current in real-world usage, as it is listed as a maximum.
