FPVERA 3.7V 1200mAh Li-ion Battery 2PCS 3.7Volt Rechargeable Batteries with USB Charger Cable SM-2P Plug for RC Car Drift Monster Truck Off-Road Vehicle Remote Control Car High-Speed Climbing Racing

Works well. Batteries are the size of a double a so check the you because they may be too big to fit. No problems otherwise

My son got a few RC toys for Christmas and I got these extra batteries so that there is always a charged battery for his toys. The come with USB charging cables for each battery and work with pretty any electronic toy

These worked for one RC but not both These are about 2" long. Measure the compartment. They have great life and comes with two chargers.

I had to replace the battery for my bubblegun and this was the perfect replacement. Good price and charges well. It works well and it fits in the bubblegun battery slot perfectly

When the easter bunny brought a bubble gun, the main concern was running out of bubbles, and running out of battery, especially when it takes 3 hours to re-charge the battery it came with. This was a great value to add extra batteries to make sure we always have one charged and ready to go when the kids want to play in the bubbles. The provided two additional batteries, and one extra USB charge cable.

Batteries charged up easily. Functioned perfectly and charge lasted longer than expected. Only drawback was size. They didn't my application. NOT THE PRODUCTS' FAULT. My bad. I still would recommend.

Used to replace batteries in our bubble guns during a jog a thon so we can keep using the bubble guns.

Since the Zuru Bubble Blaster from Costco does not have great battery life when you have a bubble obsessed LO, it's great to have these two charged and on deck to swap out.
