# Check all batteries with a LiPo checkers
# Order them by tension, group them accordingly
# Before chargincharging, plug all the batteries on the parallel board WITHOUT the balance plug. When the batteries equalize, some important current can flow throught through them, the balance plug may burn if the board is not current limited
# Start charging and look at the cells tension to see they are all pretty much the same (~1-2V)
# Monitor the whole process, never charge unattended
