The PLXNYLB 48V 22.4Ah is a hailong style downtube battery that houses 1075Wh of capacity in a waterproof design with a curved body. This is a lightweight battery at only 8.95 pounds relative to its capacity. Included with the PLXNYLB is a 3A charger, a 5-pin mounting plate, security lock keys, and an LED display showing battery charge levels.
According to the manufacturer, the PLXNYLB 48V 22.4Ah is rated for use on motors from 250W to 2000W, covering both the entry level hub motors commonly used by commuters and the higher powered motors associated with mid-drive conversion kits. Several features stand out regarding the PLXNYLB. The 50A BMS is much larger than the 30A BMS units that are often found on lower priced batteries in the same class. The 22.4Ah capacity is higher than the more commonly used 20Ah packs, and the 3A charger is another welcome addition to the package, reducing charging times compared to the standard 2A chargers that are often included with competing batteries. Some Amazon reviewers mentioned that they used the PLXNYLB as a replacement pack for their Windone E2 and other similar ebikes, indicating that this battery has developed a niche in this market segment.
Specs and Value
The main specifications of the PLXNYLB are 48V nominal, 22.4Ah capacity, and a total of 1075Wh of stored energy. The PLXNYLB offers a greater amount of capacity than the standard 20Ah batteries in the 48V class, offering riders a substantial improvement in range while adding relatively little additional weight. According to PLXNYLB, the expected lifespan of the battery is greater than 1500 complete charge and discharge cycles, translating to a number of years of regular riding before a significant loss of usable capacity.
Physical specs
The battery measures 14.47 x 3.7 x 4.17 inches and weighs 8.95 pounds. The unique curved design of the battery is a notable departure from the boxy shape of most hailong batteries. The battery attaches to the downtube of the bike via a 5-pin base plate with a keyed locking mechanism. The waterproof case is designed to provide some peace of mind when riding in wet weather as it will provide a degree of protection to the internal electronics from moisture.
Included with the purchase is a 3A charger, which is faster than the standard 2A chargers that are included with the majority of competing batteries. Using the 3A charger, it would take approximately 7 to 8 hours to recharge the 22.4Ah battery from completely discharged. Most riders will not deplete the battery to zero prior to recharging, so the actual recharge time will be less. The included LED display shows the current charge level of the battery, and the security keys allow you to disconnect the battery for indoor charging.
BMS and motor range
The 50A BMS in the PLXNYLB is a significant upgrade over the 30A units that are found in the majority of mid-range ebike batteries. The 50A BMS provides overcharge protection, over-discharge protection, short circuit protection, and a power equalization chip to maintain voltage stability. When calculating the maximum theoretical output of the BMS in a 48V system, we find 2400W. This correlates with the specified motor range of 250W to 2000W. The 50A rating indicates that this battery can support higher power motors without the BMS limiting the output due to overload.
The 50A rating is important for riders operating 1000W or 1500W motors, providing additional headroom compared to a 30A BMS. For riders that are building a conversion kit utilizing a high-powered mid-drive like a Bafang BBSHD or similar, the 50A BMS makes this battery a viable option. PLXNYLB offers a one-year warranty for this product.
Form Factor and Compatibility
Hailong is one of the most popular designs for aftermarket ebike batteries. The PLXNYLB follows the standard form factor, attaching to a mounting bracket on the downtube of the bike frame via a 5-pin connection and locks into position with a key. While the curved design of the PLXNYLB differs somewhat from most hailong batteries, the 5-pin mounting plate is the standard configuration for this form factor.
Multiple Amazon reviewers have confirmed that this battery fits the Windone E2, and others have confirmed it works on Kettles ebikes and similar models. If your bike currently has a hailong style battery mount on the downtube, then it is likely the PLXNYLB will fit. Check the clearances on your downtube to confirm the battery dimensions of 14.47 x 3.7 x 4.17 inches will fit your bike frame.
Also verify the discharge connector compatibility with your controller, as the listing does not clearly specify the connector type. Checking with the seller before purchasing is a good idea if you are unsure about connector compatibility.
Real-World Range
With 1075Wh of capacity, the PLXNYLB 48V 22.4Ah is among the higher capacity single battery options available in the 48V hailong form factor. On a 500W motor with moderate pedal assist on flat terrain, 35 to 50 miles per charge is a reasonable expectation. On a 1000W or 1500W motor with heavy throttle on varying terrain, expect to achieve a range of 20 to 35 miles. The 1075Wh capacity will still provide a considerable amount of energy even on a 2000W setup.
One Amazon reviewer indicated that the battery doubled their ride distance, which is consistent with moving from a smaller stock battery to a 22.4Ah pack. Daily commuters with round trip distances of 15 to 30 miles per day will likely be able to meet their needs for an entire workweek on just two or fewer charges.

What Amazon Reviewers Are Saying
The PLXNYLB 48V 22.4Ah has a 4.6 star average based on 21 reviews on Amazon. The majority of the reviewers were pleased with the battery and several reviewers commented positively on the fact that it worked as a direct replacement for their stock pack.
Multiple Windone E2 owners have confirmed that the battery fits their bike perfectly. One reviewer said the battery fit on the socket and the bike started right away without issue. Another reviewer commented that the battery doubled his ride distance and easily fit on his Windone E2. A third reviewer complimented the seller, stating that he had no problems with the product.
There is one negative review worthy of note. One buyer gave the battery 4 stars and stated that although it worked well as a replacement initially, the battery cycle life was not great and the battery was not at peak power after only a few dozen complete charge and discharge cycles. This is something to keep in mind, as the majority of reviewers have not experienced similar issues.
Some of the additional positive comments include a reviewer who stated that it was the perfect replacement battery and complimented the seller for helping him resolve a shipping issue. Another reviewer bought the battery as a spare battery for their Kettles ebike and was happy with the product.
Who Should Buy This
The PLXNYLB 48V 22.4Ah is a strong contender for riders that require a high-capacity replacement battery with a robust BMS. The 1075Wh capacity provides more range than the standard 20Ah packs, and the 50A BMS provides ample continuous output to handle motors up to 2000W. The included 3A charger reduces charge time compared to the majority of competing batteries and the waterproof case adds durability for all-weather riders.
The PLXNYLB is a particularly strong contender for Windone E2 owners and riders with similar hailong-style ebikes looking for a direct replacement or upgrade battery. Multiple reviewers on these specific models have verified fitment, providing a degree of assurance for riders with those bikes. For riders building a conversion kit with a higher powered motor in the 1000W to 2000W range, the 50A BMS makes this battery a stronger competitor than the majority of competing batteries that utilize 30A BMS units.
The one cautionary comment made by reviewers regarding degradation of the battery after a few dozen charge and discharge cycles is worth noting. If long-term reliability is your primary concern, you may wish to monitor the performance of the battery over time. However, for riders seeking a high-capacity, high-output hailong battery at a competitive cost per watt-hour, the PLXNYLB 48V 22.4Ah is a viable option.
