I am currently upgrading my existing Electron-based counters with newer Boron-based ones. As I do, I will rework / recycle as much as I can from the older units to reduce waste. These units have been operating on solar power for anywhere from 1 to 4 years.
How can I tell if it is time to replace a Single Cell LiPo Battery? Here is the battery I currently use: https://www.adafruit.com/product/2011 I thought it would be straight forward to test the internal resistance of the batteries (at a consistent charge / temp) as the resistance goes up as the battery ages. However, I am struggling to find a battery tester / charger that will measure a single LiPO cell’s internal resistance. I have tried both of these: - Tenergy: https://power.tenergy.com/tenergy-5-in-1-intelligent-cell-meter-capacity-checker-battery-balancer-battery-discharger-internal-resistance-tester-esc-servo-ppm-tester/ - HTRC: https://www.amazon.com/HTRC-Charger-Battery-Balance-Discharger/dp/B07MWSW3TP/ref=sr_1_4?dchild=1&m=A193SNVHREJU7H&marketplaceID=ATVPDKIKX0DER&qid=1614968073&s=merchant-items&sr=1-4 Any suggestions?
