Excellent worth the price

These batteries are the best ever. I bougt 3 of them about 5 years ago and all 3 survived a long term storage. They are still able to power a 250 racer quad without noticeable loss of capacity. I got similar batteries of other brands, also rated 40C and all of them are degraded after a few years unused. So, these Rhinos are simply WORTH THE PRICE

Great battery. Lost count as to how many times I've drained and recharge 2 of these I bought, but they are still going strong.

previously i gave both batteries 5 stars for their performance. soon after the review, both batteries puffed. i'm disappointed because i never used both lipos long enough for the batteries to puff. i will try another brand of lipo batteries.

Hi RCer,Over time I have tested different Lipo's mostly 3s.Any that Discharge below 10.5V had less life than the others that I test along side of each other and I only let others drop down to 11.3V.these lipos lasted longer or should I say held volts over time much better during Discharge. It Does not seem like much but it did affect lipo's life over time .3.3V per cell on a 3 cell total volt is 9.9V total I would tell a friend to at least stay above 10.9 on a 3 cell lipo.As for myself all of my 3 cell only Discharge to 11.2V or 11.3V per cell! and they have lasted for over 100 cycles.Try testing two of your new lipos and see what you come up with.Any Brand as long as they are the same name and mAh during test. I do know that the maker of lipos say something different in the Discharge department.And they would like us to buy more lipos.stay up RCers!!

this is a top quality battery. been using it for a couple months with my power hungry 64 mm ducted fan gliders. stays cool. sometimes warm but never hot. pricey but worth every penny.

I have two similar packs, after 8-10 charges both look like they're about to explode and lost a lot of power. I'll buy other types from now on.

I bought two and all of them are useless. There are voltage table, measured about 30 minutes after flight when battery is cooled down. Directly after flying some cells have less than 3V. LiPo alarm set to 3.4V per cell!! after first beep of alarm i have to land immediately, because in few seconds ESC starting to cut off power (set to 3.3V per cell). Last flight LiPo alarm started to beep while after ESC cut off power. My old turnigy 2200 40C have almost equal V per cell even if measured directly after flying. Worst LiPo i ever seen :(
