I needed more than one Charger to do myLi-P0 batteries I used from a day of flying. My choice I thought I would try this Imax Unit. I had an extra power supply just needed a charger with the connections that come with it . It seems to be working fine. By having a couple charging at the same time it reduces the time element you have after a days flying.It was also nice it came with T-connectors for the charger. It matched up with what I was already using.Up to 6 cells is more than enough for the average flyer.Once you've used a few times it pretty easy to operate. Value Hobbies has helped me again. Thank You.
