HOOVO7.4V 80C 5200mAh 2S Lipo Battery Hard Case with EC5 Connector for RC Car Truck Truggy Buggy Tank RC Airplane Helicopter Boat Car Racing (2 Pack)

I bought these to use in my Promoto-MX because I didn't want to change the connector on the bike to XT60 which is what I normally use. This was the 1st time I bought the Hoovo brand battery but the price was good and the size seemed ok to fit into the battery compartment of the Promoto-MX. They with a storage charge and when charged had very little resistance. The fit very well into the battery compartment and I could even hide the balance cable in the compartment so it did get torn off in a crash or something. Ran it in the grass in the dirt mode and got 11m 52s before it went into LVC didn't time the stock battery that came with the bike but I think it was around 9m for so. Can't say yet how they will hold up to long term use but as of now I am more than happy with my purchase.

Love the price! The run times are similar to all other 5200mah 2s batteries. I run mine in a Traxxas TRX4, and a Losi PromotoMX. I get 16-18 minutes of run time on my PromotoMX motorcycle. That's as good as, or better than others have reported. Very happy with purchase, and will be buying more on Amazon. 2 for $30 is crazy!

Very happy with these batteries. I have used them under extreme conditions. They have never let me down

It came earlier than I expected both batteries keep same voltage which is important when running 2 batteries in a rc truck don't expect anything to go wrong minus normal wear for use

Bought a few Hoovo brand 2s and 3s lipo batteries to use with my RCs. They work well. No issues with charging, using, or storing them. Good cheaper lipo batteries.
