Thank you!
I think that’s not really safe against short-circuit. In between I’ve found the solution with ties:
I hope that will work, but it shows that another charger has to buy.
One additional question for charging Eneloop:
What’s the difference if I use NiMH charging program or Eneloop charging program?
Additional (apart the MC3000): are there any differences in charging strategies of NiMH and Eneloop, like charging-end-voltage or something else? Can I always charge Eneloops with chargers that are only capable of charging NiMH and do not have any extra program for Eneloop?
