Hi All,
i am planning to extend the flight of my drone, by adding a 2nd battery.
The max payload of my drone is more than the weight of an additional battery, so that is not the problem.
For now, I have designed a docking station that comes in place of the original battery and that has a cable splitter, so I can connect 2 identical Lipo's through that. I will carry the 2 Lipo's externally in a bay, between the landing gears.
The question is about the connection. I have understood that parallel connection can be done safely when voltages are between 0.1 difference between the 2 lipo's. I can measure that after charging and balancing.
What should I expect at connection time... heat building-up while the 2 batteries even out ? Is it safe ? Are there additional precautions to make ? Should I keep them in parallel during charging ? In that setting I can not balance charge them I presume.
Is it a good idea ?
