Hi Everyone, I just thought I would write a review since no one else has. I bought these batteries about a month ago, I was like so many other people, I was tired of the poor performance of the stock eflite batteries only lasting 20 cycles or so. Well, what I've found is that these batteries have way more punch, run cooler, and after 20 cycles are still performing like new. That being said, here is what I do and don't do. Never charge at more than 1c or .5 amp Never drop these batteries, all[More…]

Perform well. The only problem is that the plastic caps have come off all of the 6 batteries I purchased. This makes it more difficult to remove the battery from the 120SR battery tray. I've attempted to use superglue to re-attach the caps.

I bought two of these Protek batteries and plan on buying more !! The run times for these packs compared to the E-flights is a LOT better !! The only problem I've had is that the end caps will pull off if you're not carefull ! Make sure the connections inside the cap are ok then a very small dab of hot glue and you're back in business !!

I have flown 2 Blade SR 120 helicopters on these batteries. The one I'm using now is still my best battery of 5 different brands and, after checking the e-receipt for it, I bought 2 of these in April 2011! I lost one in a massive crash last Fall (which I forgot about the guarantee I should have used), but the one I have now is still from the original two I purchased... and it still out performs my other batteries.
