  • Fast 6 hour charging time


    • When using this charger, the battery can still output power while it is charging.

    This battery output terminals are separated from charge port. Charge battery from charge port only. Do not charge the battery from output terminals. The charger will control charging voltage and current. Internal circuit will provide over charge and over discharge protection, but will not control charge voltage and current.

    Applications:

    1. Directly use this battery to provide power:

    This battery output voltage range is 21V ~ 29.5V. When the battery is fully charged, its output voltage is 29.5V. The output voltage will drop gradually during the discharge process and the final cut off voltage is 21V:
    Only use this battery with devices that can accept every voltage in the 20-30V range and require 500W or less power.


    2. Use this battery with a DC to DC converter to to provide different voltages

    This battery output voltage range is 21V ~ 29.5V. This output voltage can be converted to different voltages to meet different needs by using DC to DC power converters.

    3. Use this battery with a DC to AC Power Inverter to provide 110V or 220V AC power

    This battery's output voltage range is 21V ~ 29.5V. You can use a 24V DC to AC Power Inverter to convert DC power to 110V or 220V AC power.

    4. Use the single 24V lithium ion battery to replace two 12V lead acid batteries connected in serial:

    You may use this single 24V lithium ion battery to replace two 12V lead acid batteries connected in serial. This battery is perfect for devices that need up to 500W power, such as 24V motors in electric scooters and electric wheelchairs.

    The Toy That Tires Out Your Dog So You Don’t Have To!
    Color: Classic Blue, Color: Classic Blue
    After trying a different interactive ball previously, I can confidently say this one is built much better. The construction feels more durable, and most importantly, it has held up well against my dog's enthusiastic chewing and chasing. Many interactive toys claim to be tough, but this one has actually survived extended play sessions without being torn apart. The charging design is simple and well thought out. The ball twists apart easily to reveal the USB-C charging port, making recharging quick and convenient. Once charged, you simply twist the halves back together, press the power button, and it's ready to go. I appreciate that there are no complicated steps or special charging accessories required. What really stands out is how engaging the toy is. The unpredictable movement keeps my dog interested and encourages plenty of exercise and mental stimulation. Instead of losing interest after a few minutes, my dog continued chasing, pawing, and interacting with the ball until he was genuinely worn out. For pet owners looking for a way to help burn off excess energy, this toy definitely does the job. One minor issue I noticed is that on a couple of occasions, my dog was able to accidentally turn the toy off while carrying it in his mouth. It wasn't a frequent problem, but it did happen enough to be worth mentioning. Fortunately, turning it back on is quick and easy. Overall, this has been one of the better interactive dog toys I've tested. It's durable, easy to charge, keeps dogs engaged, and provides the kind of activity that leaves them happily exhausted afterward. If your dog enjoys chasing moving toys and you want something sturdier than many of the alternatives on the market, this is a solid choice.

    Great Entertainment, Short Battery Life
    Color: Classic Blue
    This is the first interactive ball I've found that my dog hasn't managed to destroy, which is impressive on its own. The ball keeps him entertained for long periods, and he loves chasing, nudging, and following it around the house. The material feels durable and has held up well to regular play. The one button operation is convenient, and the ball is easy to recharge and clean. My biggest complaint is the battery life. On a full charge, it only seems to run for about 10 minutes before needing to be recharged again. Because of that, I find myself charging it frequently. Even with the shorter runtime, it's been one of the more engaging and durable interactive toys we've tried. Overall, a fun and sturdy toy that keeps dogs occupied, but be prepared for frequent charging.

    Fun Dog Toy
    Color: Classic Blue
    This toy has been a lot of fun for our dogs. One of my dogs absolutely loves balls and is perfectly content to just carry this around in his mouth. The outer shell feels like a firm foam material. It is durable while still being lightweight enough for the dogs to enjoy. The ball screws together, but it is designed well enough that you are not constantly worried about it coming apart. You have to intentionally press and twist it to open it, so normal dog play has not caused any issues. Inside is the motorized component, which is easy to turn on and recharge. It offers a few different vibration modes, which keeps things interesting. The reactions from our dogs have been hilarious. One dog is convinced the ball might be plotting against him and keeps a suspicious distance. Another dog loves it so much that he holds it in his mouth while it vibrates, making his entire head shake. Our third dog plays with it exactly as intended, chasing it around and interacting with it normally. The motor has enough power to make the ball bounce, roll, and move unpredictably across the floor, which keeps the dogs engaged. It has been a great addition to our toy collection and provides a different kind of enrichment than a standard ball. Overall, the dogs really enjoy it.

    A fun toy
    Color: Classic Blue
    Our Malamute loves this ball. He likes to carry it around with him and let it will out of his grasp and pick it back up. The outer ball it tough and durable, and so far it has held up well during play. It does bounces more than rolls I expected a little more movement across the floor in a more rolling fashion... like those weasel balls from the 90s, but tends to hop and bounce in place. It does works best on hard floor where it has enough contact to move around and keep the dog engaged. To charge you have to unscrew the ball in half to access the motor unit, and there is grease on the motor, so be careful when opening it and handling the internal piece. It is not difficult, but it is a little more complicated than a simple plug-in charging port. The button on is also super hard to press. I you have to really squeeze it and even use a tool to turn it on. It has 2 modes though it is so hard to press I am not sure which mode I actually turn on. It so far has been a fun toy for our young dog and has lasted our extreme chewer (only supervised play) I would recommend if it went on sale.
