You did not answer the question, if Anafi does not calculate the remaining charge based on the cell voltage, then on what basis? Because if cell voltage were the basis for the calculation, an aging battery would reach 2% charge sooner where it turns off.1. For used Anafi battery. There are two methods. First, is to drain it once just likes the video. If it falls. You know what to do. But you must charge it back to nominal voltage (1-2 leds) immediatley after the test or it will degrade significantly within days if remains totally empty. The second method is you get it fully charged at 100% before you go sleep. On next morning. Check again its % percentage. If it has already dropped to 95% or lower. It can be considered to be retired. For a new lthium battery, in the RC airport. professional RC players usually would strictly follow the 3.7v per cell rule (11.1v for 3S) on each flight to maintain the lithium health cycle. They would also use a small paper note to note down each discharge cycle. When the no. of discharge has reached to an expected number (such as 100 times). The battery is retired. They retired the battery first before to let the crash happens. I also do this way on Bebop 2. That's why my Bebop 2 could last for 2000 times flight spreading across 4 generations of battery replacement cycle within 4 years. Due to the discharge is always being controlled to not less than 3.7v per cell on each flight. So the estimation of day of retirement can be quite precisely.
2. Only choice is offered. Nothing more. Which choice to take is not a concern. As battery is not a very profitable goods. That's why preferring customers to buy the Parrot stock battery first. (for battery only, You go bother Parrot, don't bother me). In case people also need the Mod. My super bundled offer can help. The plan for the returning customer has already been described.
In whichever case, for the first time of purchase. The amount you spend for 3 batteries is very same. Because you buy it or not will not gain too much profit so no one really cares. My practical offer is I let people to know the truth and reality. Which may change the destiny of your drone. This's a major contribution. Thus, I have already offered my part for all people. Don't request further unreasonably.
In short, need battery only. Just go Parrot to help yourself.
Maybe you measure the elapsed time?
This problem could be aided by a firmware that monitors the cell voltage. So this is a firmware error because it does not take into account the specifics of the battery.
The 80% crash is not a hardware failure in my opinion ...
In any case, the useful advice you gave is not to submerge below 43%, but the solution is a firmware that informs you about the charge based on the battery voltage and brings the drone home safely when the battery voltage requires it.
