I've had 25-30 models in the last 5 years, probably a hundred batteries. there are 32 actively used packs here now. if you solder them when there is a male and female together, there is zero chance of them coming out of alignment...... Those help people by not needing heat to melt 10 or 12 gauge wire on the plastic, then the tip solder on fast,,, it's like a dji esc. I've never had a failure in flight, but i've caught em on the ground where the spring needs some spring in it. if you ever plug it in and think you heard it boot twice, bend that spring..... it's as simple as that. IF there hard to plug and unplug, it's cause you didn't solder them as a pair and the bars moved,,,,, it's really simple. Works fine
The only reason i'd use power poles is if i had a high amp and high voltage draw like big single rotors use. 44 volt, 120 amps, needs something more than a 75 amp rated deans,,,,, i think it's 75
