The VBWEQAD 48V 13Ah battery is designed to fit into a Hailong/Shark frame slot, providing a clean, integrated design to improve overall aesthetics while also placing the battery's weight near the center of the frame to enhance ride quality and stability.
Specs and Form Factor Details
It is important to note that the Hailong/Shark battery form factor is only compatible with frames that have a Hailong/Shark battery slot. If your frame does not have such a slot, then this battery would not be compatible with your frame.
Motor Compatibility: 500W to 1500W
The 500W to 1500W motor range is quite wide and leans towards more powerful applications. The 500W bottom end indicates that this pack is intended for applications that are slightly above minimum power, and likely not for very low-powered commuters or other applications.
A 1500W top end is significant for riders that are using either high powered hub motors or mid drive systems that pull a lot of amps during periods of hard climbing or prolonged high assist operation. Many Hailong form factor batteries are not rated at the 1500W level, so the extended upper limit is a useful point of differentiation for riders that are looking to build a more powerful application.
Bafang BBS02 Compatibility
The fact that the VBWEQAD 48V 13Ah battery is listed as being compatible with the Bafang BBS02 is worth noting, as mid drive applications have specific requirements that are not always clearly defined in generic compatibility statements. Bafang BBS02 kits operate at 48 volts and can draw considerable amounts of current, especially during hard climbing or sustained high assist periods. It is reasonable to assume that a battery that is specifically listed as compatible with the BBS02 is capable of delivering enough power for these types of applications, although you should always confirm the type of connectors provided before making your purchase.
Bafang BBSHD kits tend to draw even more current, particularly under high assist conditions, and therefore require a battery that is equipped with a BMS that is sized to handle that kind of current draw. Always verify that the BMS current rating matches your particular motor's maximum current draw specification prior to making your purchase.
Why Hailong Form Factor Matters for Conversions
The popularity of the Hailong/Shark form factor is largely due to the fact that it allows conversion builders to create an integrated battery appearance without having to use a custom frame. Many Chinese market ebike frames feature Hailong slots as standard features. Additionally, many conversion kit vendors provide frames that were specifically created to be used with a Hailong battery.
If your frame includes a Hailong slot that is compatible with the correct dimensions, a Hailong battery is usually going to be the best option instead of an external box battery. An internal Hailong battery will allow you to position the weight of the battery much closer to the center of the frame than an external box battery, which will result in improved handling characteristics. The internal battery will also be more protected from road debris and harsher weather conditions than an external box battery. Finally, a Hailong battery is mounted securely to the frame via a locking mechanism, eliminating the need to rely on straps or bags that can shift over time.
The drawback to a Hailong battery is that they are generally not interchangeable with other form factors, and are therefore only suitable for frames that include a compatible slot with the correct dimensions.
Evaluating the Listing
Since VBWEQAD is a relatively unknown brand name, and the number of user reviews related to this particular listing are very limited, there is no substantial body of evidence upon which to evaluate the actual performance of this battery. However, the relevant specifications (48V, 13Ah, 624Wh, Hailong) appear to be consistent with the specifications provided by reputable manufacturers of cells in this build configuration. The BMS appears to be sized adequately to support the specified motor compatibility range.

Who Should Buy This
This is a good product for riders who are creating a Bafang BBS02-based build, or any similar 48V mid-drive kit on a frame with a Hailong/Shark battery slot. The 624Wh of storage in this battery provides a good amount of reserve for a commute of approximately 15 to 25 miles each way, the upper limit of the motor compatibility range (1500W) provides additional margin for more power hungry applications, and the Hailong form factor provides the integration into the frame that an external box battery cannot.
If your frame does not have a Hailong slot, or you are using a lower power motor that does not map directly to the 500W lower bound of the motor compatibility range, you may wish to consider other options, including external box batteries, or other battery form factors listed in the battery comparison table.

Frequently Asked Questions
How do I determine whether my frame contains a Hailong-compatible slot? Slots that are compatible with the Hailong/Shark battery form factor are of a specific width and contain a particular mounting rail configuration. Most conversion frames that are sold specifically for ebike builds will specify that they are compatible with a Hailong slot. You can measure the slot on your frame, or consult the documentation for your frame. If you are uncertain as to whether your frame contains a Hailong-compatible slot, you may wish to opt for an external box battery with a flexible mounting system.
Is this compatible with Bafang BBSHD as well as BBS02? Although the manufacturer lists the VBWEQAD 48V 13Ah battery as compatible with Bafang BBS02, it does not state whether it is compatible with Bafang BBSHD kits. As previously noted, BBSHD kits draw considerably more current during high assist operation than BBS02 kits, and therefore require a battery with a BMS that is sized to meet their high current demands. Therefore, although the 48V voltage is compatible with both motors, you should verify that the BMS current rating meets the maximum current rating of your BBSHD motor prior to purchasing the battery.
What is the expected range with a BBS02 using 624Wh? On flat terrain, with a Bafang BBS02 operating in PAS 1-2, 624Wh of energy storage is likely to provide 30 to 40 miles of range. Lower ranges are typical for hilly terrain, and operating the motor at higher assist levels or on steep inclines. Range will be severely limited in PAS 5 or using the throttle on a climb to 15 to 20 miles.
Are chargers provided with the battery? Please refer to the current listing to determine what accessories are provided with the purchase price. Most Hailong batteries are shipped with a corresponding 48V charger, but the amperage of the charger is variable and will impact charging time.
Can I use a non-Bafang controller with this battery? Yes, as long as the non-Bafang controller is rated for 48V, and the connector types are the same as those used with the Bafang BBS02, you can use a non-Bafang controller with this battery. The Bafang BBS02 compatibility statement is a reference to that specific motor kit, and does not imply that you can only use Bafang hardware.
Is the Hailong form factor waterproof? While Hailong batteries are somewhat weather-resistant due to their sealed casing, waterproof is generally not a characteristic of most Hailong batteries. Rain or snow ridden rides are usually acceptable, but submersion or hosing the battery down is not. Cover the charge port whenever the battery is not in use to protect it from water intrusion.
