RC ERA C138 / C138-Pro Battery

These batteries are a must have, they have a very good flight duration and very reasonably priced.

Works perfectly with both the C138 and C138 Pro. Buy one and you wont regret it.

Batteries are great! Last a long time in flight! At least 10 min.

Got 4 of these and they give you a nice amount of flight time

Great backup battery. Allows a good 8 min flight.

Purchased two extra batteries to go with C138 Bell 206. They give me about 8 minutes of flight time per battery before low battery lights begin to flash. The side clips were loose when they arrived. The batteries would fall out if landing hard. I applied a little heat with a heat gun to the sides of the battery while small pieces of popsicle sticks were inserted behind the side clips. Be very careful not to overheat the sides of the battery. They now clip firmly to the bottom of the helicopter.

I purchased this battery for my C138 copter. It fits but I wish it snapped in place so it feels secure and won’t fall out

Shipping was super-fast and well packaged, batteries were fresh and gave me 12 min. of power, would buy again.
