1. Under the "Power, battery & charging" heading the picture of the JST plug shows a black and red wire. However, your link to Digi-Key JST ASPHSPH24K152 is only a black wire, what is the part number for a red wire?
2. Under the picture is a warning that says "...exercise case...". Think this should be "exercise care".
3. The 2nd paragraph states "The CurrentRanger requires a standard Lithium Polymer/Lithium battery that charges to 4.2 V". What if I want to use an analog DC power supply set to 4.2 V? The common of the power supply output is not connected to the mains ground or neutral line, it is floating.
4. You need to use proper SI nomenclature. There is always a space between the value (the number) and the following SI letter symbol. And no attachment is made to SI letter symbols. That is "5VDC" should be "5 V DC". Refer to ANSI/IEEE/ASTM SI 10, NIST Special Publication 811 (a no cost PDF download), or ISO/IEC 80000-1.
1. No red is carried by Digikey that I could find. A fully assembled harness is here (https://lowpowerlab.com/shop/product/168), or a battery can be purchased with the kit.
2. Fixed, thanks.
3. Use at your own risk. The "SI" for this guide means if you plug in USB it will try to charge the attached "battery".
4. Nothing unclear about 5VDC, everyone gets it. No changes.
