Hexfly 2S 20C 7.4V 5000mAh LiPo Battery Hard Case Banana 4.0mm

I bought this for a Red Cat Caldera. I had to cut the body/chassis to get it too fit as it was mentioned so no big deal. At first it was great. Long life and LOTS of power. I used it 3 times and after that the 1st cell would not charge, only the second one did. If the first cell is no good the second one makes no difference. Battery is no good. I contacted seller through Amazon and they couldn't help at first me and referred my complaint to the manufacturer for warranty. Hopefully they will make good on it. I'm still waiting...Well after a month and multiple emails and a failed A-Z Claim through Amazon, Radio Controlled Toys Online refunded me back 1/2 the cost of another battery after buying it through their storefront. I was out of options so I was happy with R.C.T.O. offer. I would be sure my next RC order went through Radio controlled Toys Online.

Great battery as advertised no issues. I like that it comes with a variety of banana clip plugin connectors that attached directly to the face of the battery instead of to the end of the dongle. also has the charging monitor cable neatly wired directly into the adapters. Only downer is that the plugs stick out perpendicular to the battery face so if you have a tight clearance for your battery compartment it might be irritating.

Has tons of power, but for 56 dollars it should last longer than 9 months and between 30 and 40 charges.

I use this Lipo's in my redcat racing terremoto. They work great. The plugs come out of the side, so I had to modify my RC to make them fit, but it was worth it.

It's no Nano-Tec, but still pretty good.

Use it in a Stampede 4X4 VXl, Monster Jam series XL5 and upgraded VXL. Fits good in battery area.

Tons of power and long life. Cool carbon fiber look and fits perfectly in my redcat caldera. Came in quick in good condition I will buy again.

Good battery life awesome service would butt again well built case charges very well no problems easy of use a++++++
