503040 600mAh Lipo Battery Replacement for Cozmo Vector Robot SkyBell HD WiFi Video Doorbell Flysight FPV Watch Dash Camera GPS Driving Recorder Wireless Speaker

Bought for a Vector robot battery replacement. It fits but only just. If you can do that upgrade then the slight oversize isnt a problem. So far the capacity seems very good.

Was for Vector Robot, fitted and worked well.

Battery arrive not as shown, the plug not as shown, and when I had to connect the original plug to it, it refused to charge not buying again wasted money.

Purchased to replace the worn out battery in a Anki Cozmo. Followed the instructions on the web to take the little robot apart and then replaced the old battery with this one by snipping the wires running to the old battery and then soldering them to the wires on the new battery (I removed the connector on the new battery). Reassembled, charged up and Cozmo is back to life :-)

Beware - This device is 45 x 30 x 4.7mm thick and may not fit if you are using for something other than a Cozmo Rocket SkyBell

My Bluetooth headphones stopped charging. After carefully dismantling them, found battery had swollen. This was a perfect fit and increased the capacity by 120mAh so they stay charged longer. Had to cut the plug-off and solder leads to circuit board. Have been working for almost a month and charge without any issues. Great product to repair my headphones.

Our poor little Anki COZMO had run out of energy (battery expired) Ordered this compatible replacement, stripped COZMO down, replaced defunct 320mAh battery with this 600mAh battery, reassembled, and now the little fella will run in "Free time" mode for over 2 hours! One happy Grandparent here. Can thoroughly recommend for this use.

Nearest size to original but lower capacity. This or nothing

This battery doubles the play time/capacity of the Anki Cozmo robot to about 80 minutes from about 30 minutes max on the original 320 maH battery in the Cozmo robot when it is new. The fit is snug because the battery area has a maximum length in the enclosure of exactly 40 mm. The specific model number of this battery (503040) means the battery is 5.0 mm thick, 30 mm wide, and 40 mm long. The original battery is 503230. Many Anki Cozmo robots were manufactured in 2017, and LiPo batteries of this type often start to fail after about 3 years - especially if they have been used and recharged multiple times. Failure is usually apparent with inability to connect (or stay connected) to WiFi, or sudden shutdown after only several minutes. The beauty of this battery is that it already comes with a ready connector, so you have the option of soldering in a two-wire (+/-) female connector onto the battery connector board (easily obtained from RC supplies stores, ebay or Amazon), or just snipping the wires to fit, feeding them through the circuit board to the correct areas, and soldering them on to the board. There are excellent videos on YouTube that instruct how to do this (for people who don't mind DIY). For $20 you can completely renew and upgrade your Cozmo and not have the wait time of sourcing direct to China through a site such as AliExpress - which may take 1-2 months.

Bought this for an anki vector, the battery is progressively getting worse with each charge, after about 10-12 full cycles the battery capacity is down to about 44%, had to buy a new battery from a different vendor and replace it. Tested the battery on its own and is accepting about 280mah

Ich habe den Akku für unseren Cozmo bestellt. Funktioniert einwandfrei und der Akku hält auch länger als der originale.

Utiliser pour upgrader un cozmo, cette batterie ne m’a pas fait défaut et offre uns plus grande autonomie au robot. Le logement est un peu juste cependant mais en forçant un peu ça rentre

Very good for my Cosmo, fits perfectly. Very good for the price and soldering it was very easy. Battery lasts around an hour and 30 minutes. Plenty of play time.
