Battery p/n and mAh rating for CurrentRanger
« on: October 12, 2021, 03:21:41 PM »
Hi all, new here.

I understand that for the CurrentRanger, the website indicates to use a 3.7V Li-Po or Li-Ion that charges to 4.2V via MCP73831 IC with a 454mA charge current.

But what does this correspond to in terms of battery? When searching online for Li-Po or Li-Ion batteries on Amazon for example, there are pages and pages of these types of batteries...

So... does anyone have a specific part number with a direct link to a known working battery that they have personally tested with the CurrentRanger?

On Amazon, I see like PL505573 @ 2500mAh or LP503040 @ 600mAh or PL583450 @ 1500mAh... so which one should I get?

Thanks!

That there are many, it's a good thing. Choose something local that won't take 3 months to ship from our commie friends.
The problem with providing a specific link is they can be valid for a week and then be gone.

Anything between say 500-2000mAh is sufficient, you're more concerned about the size to ensure they fit inside the box, and the JST PH2.0 connector to be the right polarity (although it's relatively easy to swap the 2 wire/connectors inside the connector housing (ex. with tweezers) to ensure correct polarity.

For instance Welectron sells a 503035 (3.7V, 500mAh) battery to accompany the CurrentRanger, but also there is a 1500 and 2500mAh option.
