#skyrc #mc3000 is a Universal Battery Charger and Analyzer. I am having major issues understanding the meaning of the capacity information shown at the end of a refresh cycle for some #liion #liionbattery 18650 protected batteries (https://www.akkuteile.de/keeppower-18650-4000mah-3-6v-3-7v-li-ion-akku-geschuetzt-pluspol-erhoeht-p1840c_12099_3332). Basically I do not know if the capacity information at the end is the correct info for the charge or discharge value of the battery in question. Anyone know how to interpret the data show as "capacity" ?

#skyrc #mc3000 is a battery charger & analyzer 120€ from Amazon https://amzn.eu/d/0bsrltPF . It has an app called "SkyRC MC3000" in Google Play Store. (The QR code, to get the app, in instructions do not work.) It has a "refresh" mode where it charges, discharges & then charges batteries. All the while it shows "capacity". The video shows the capacity info (and other info) at the end of the refresh program. The image shows what the LCD shows. The capacity in app seems to be rubbish (I hope). 1/2

2/2 ... Want to make sure that my 3 batteries (Keeppower 18650 4000mAh Li-Ion-Akku Protected raised + pole P1840C Art.ID: 12099 https://www.akkuteile.de/keeppower-18650-4000mah-3-6v-3-7v-li-ion-akku-geschuetzt-pluspol-erhoeht-p1840c_12099_3332 ) are sufficiently matched / similar (in final voltage & capacity) for use in parallel with solar power battery manager from Waveshare (https://www.waveshare.com/solar-power-manager-d.htm?sku=26363 SKU 26363). Export data only shows the voltages over time. Guess I need to do the discharge only program to see if app tells me capacity is same as LCD info. #meshtastic #liionbattery
