Note: Balance Boards NOT included or required. Batteries can plug directly into the (2) balance ports on the front of the charger. Looking at the front of the charger, the NEGATIVE pin is on the left hand side of each balance port. Simply align the negative balance wire on the battery with the left side of each balance port.
Only slight gripe is I wish it had higher quality buttons to match overall quality. First time ordering and very happy with price & fast shipping, will order again!

Great charger
This is a fantastic charger for the price! I can now charge my 5000, 6 cell batteries (12s stick packs) at 1-2c no problems at all. Gives me more time up in the air flying. Love the size and the ISDT link app so I can see my battery stats on my phone while they are charging etc. Highly recommend.

Best charger I’ve owned
Been running rc cars for years and now getting back into heli’s. I needed a charger to charge a 14s battery and this is what heli direct recommended. I couldn’t be happier! There’s no need for balance boards, it’s very user friendly and has lots of options with an easy to navigate menu.

Great charger!
This charger has been a great addition to my 308DUO. Only problem is the need for a more thorough instruction booklet for more advanced use. Basic use is simple to figure out without the instructions though.
