Using a LiPo cell with 3.7V and a booster to 6V raises the question how to avoid destruction of the battery. I do not want to see my HP 41 go up in flames.

I have about 50 HP 41 in my home, +/-1 does not depends
No, the booster serves only 5V / 6V (depends on the module). I fact, there is still the problem, that the Lipo gets empty before the BAT flag is set.
For recharching, we modified the charger with a resistor, so that the battery is loaded slower and saver.
