The wiring diagram on this web page is completely wrong - for one thing there are 8 sets of wires not 6 as shown, and actual wire colors are not as shown in the diagram. The unit delivered had no labels on any wires or connectors, despite the photo on the web page. Look elsewhere for how to wire this unit for your e-bike or e-scooter. With info from other sources and some luck I may be able to install, although there are You Tube videos that indicate two of the wire sets (motor and charger connectors) are incorrectly made and must be reversed to work in Razor scooters. Beware: if the connectors are left as the manufacturer made them, the motor may run in reverse and the battery charger may burn out the controller unit. Look elsewhere in desertcart for the exact same unit with better, correct instructions. ## Features - ★【WORK VOLTAGE】24 Volts;Matching Motor:DC brushed motor; - ★【RATED MOTOR POWER】250 Watts;Under Voltage Protection:20V±0.5V;Current Limit:21±1A; - ★【NOTE】Please verify model number and size prior to ordering to ensure this is the correct part; - ★【WOOSTAR CUSTOMER SERVICE】Always available to help our customers.Please message us for replacement or refund if you are not satisfied with the order;Be happy Online in your time. ## Images ![A94-CO - Image 1](https://m.media-amazon.com/images/I/61Zj87VGkyL.jpg) ![A94-CO - Image 2](https://m.media-amazon.com/images/I/7118Vip51QL.jpg) ![A94-CO - Image 3](https://m.media-amazon.com/images/I/71X7jQ5p4mL.jpg) ![A94-CO - Image 4](https://m.media-amazon.com/images/I/717Q6LKAWvL.jpg) ![A94-CO - Image 5](https://m.media-amazon.com/images/I/711mOhPRVhL.jpg) ## Available Options This product comes in different **Pattern** options. ## Customer Reviews ### ⭐⭐⭐⭐ Bueno *by J***E on May 12, 2025* Muy buenos ### ⭐⭐ Wiring diagram all wrong, no labling *by G***F on January 5, 2022* This is a Yiyun Tech model LB27 controller, 24-volt 250-watt unit made in China.

The number of connectors and labeling do not match what is shown for the Product Description and Product Pictures. I purchased this for a Hyper Scooter sold by Walmart. Surprisingly some of the connectors matched the ones on my Scooter in the description so I ordered it. But when it arrived things did not match. Polarity for the Charger and Motor were reversed. I had to flip the wires on my scooter. I haven't powered this up yet because if I don't get the answers I need I'm returning it like I received it. By the way, it show signs of wear and previous installation like it may have been a return. I hope I can get my answers and get my scooter working. Well I got my response. Told me I should seek professional help if I still have questions. WOW! I quess that means they are disqualified since they could not help.
