5pcs 3.7V LiPo Battery Spare Parts For WLTOYS V911 4CH 2.4GHz RC Helicopter

I love my v911 so much I had to go out and by 5 more batteries so I could have more flying time. I can fly for about 35 min now Beats the 10 min I was getting.

I ordered these batteries from Tomtop and these appear to be the same batteries as included with the v911 as it comes from the factory. The top number printed on the battery is the same and the battery and connector appear identical. I initially had a problem with the charger not recognizing one of the batteries, but upon close inspection there was a drop of some super glue from assembly on one of the battery contacts. As soon as I scraped it off, it worked as intended. These batteries deliver flight times at least as long as those included with the helicopter. With 7 batteries and the two well charger, you can pretty much fly nonstop even with allowing the batteries to cool after flying and after charging, but I'd still recommend allowing the helicopter to rest for 5-10 minutes between flights to allow the motors to cool. They do get a bit hot. In order to maintain equal cyles on all of the batteries, I used a Brother label maker to make small labels numbered 1-7 and attached one to each of the batteries. The weight added is negligable and allows me to keep a notebook where I mark off the last battery used and if it has been subsequently charged. Overall, a very worthwhile purchase that greatly reduces the downtime between flights.

Good extra batteries for my chopper

The catalogue said the new and improved batteries would fit all the 911 helicopters. It took more than a month to get the new batteries and two orders. The new batteries came and the connector on the batteries had been changed so would not fit the helicopter or the charger.I tried to get the sender to answer questions about the battery connector, like could I get batteries that would fit. The sender responded by telling me the refund has already been arranged. I do not care and did not ask about the refund, I want batteries that will fit in the helicopter and charger.If there was a negative star to select I would have selected it.

I ordered a v911 RC helicopter for my husband at Christmas. At the same time, I ordered extra batteries. The batteries took 3 weeks to arrive and when they did the batteries did not fit. As many other reviewers have discovered, newer helicopters use different batteries. I contacted the company and they offered to send me the correct batteries if I returned the ones sent. I was happy to pay the postage as really, this was my fault. We received the batteries last week and they are correct.The process took awhile to resolve but the company made it right even though it was my error.

Batteries worked great when I received them. 3 days later 2 stopped charging and are fully dead. Note I never fully discharge them as I know lipos die if you discharge too much. Did not contact seller since I figure its too much hassle for $5.00 in batteries for a helicopter I use primarily just for giggles when I can't fly my B450. They are slightly longer than originals but after trimming remote not a problem.

These are a must have for extended flight time for your V911.I average 7-10 minutes on a single battery fully charged, so with 7 batteries (these plus the 2 that come with the copter) you're looking at roughly an hour of flight time.These really help to make it worth while when you decide to go flying outdoors.

... not to mention they arrived nearly a month after they were purchased. These batteries were the suggested addition to the purchase of the WLTOYS V911 4CH 2.4GHz RC Helicopter (Toy) . I considered it a good investment and ordered the extra batteries in good faith, making the assumption that they would be the correct batteries for the model advertised. Like ALL of the most recent reviews of this product, they are not the right batteries. Amazon is usually very good at making right multiple-customer complaints of a particular product. It would be great if they would A) reimburse/credit the buyers of these batteries purchased with the WLTOYS V911 4CH 2.4GHz RC Helicopter without making them hassle to return them, and/or B) offer to exchange the batteries with the correct batteries for no charge. It would also be helpful to remove the suggested incorrect batteries and perhaps suggest the correct ones...!
