This 36V Hailong pack offers a basic spec sheet and a convenient USB port but lacks almost any proven track record. It provides 360Wh of energy at a low cost per watt though the stock is currently limited. It is a budget gamble for riders needing a replacement battery. This is a risky choice for now.
Design and Build
What's the difference between a Hailong-style battery mount and other mounts?
The battery weighs 7 pounds which is relatively light for a pack of this capacity but you still feel the weight when lifting. The listing claims the case is waterproof. This means it might handle light rain showers if the seals stay tight over time. If the seals fail or degrade due to heat and exposure the internal cells will corrode and fail.
The plastic shell feels sturdy enough for daily use but it lacks the premium finish of high-end custom builds. You get two keys for the anti-theft lock which secures the battery to the frame. This adds a layer of security when you leave the bike at a shop. If you lose the keys you are in trouble with a battery bolted to your frame. The use of an XT60 wiring harness is a standard connection that allows for high current flow. This makes it easy to integrate into existing ebike controllers without cutting custom wires. You can find this ebike battery which uses that specific connector style.
Specs
The core of this unit is a 36V system with a 10Ah capacity. This results in 360Wh of total energy storage. This energy level means you have limited range compared to larger packs. If you go on a long hilly ride you will likely end up walking home before the trip ends. The listing claims these are Grade A cells capable of lasting thousands of cycles. I have not run this pack to verify the actual capacity over many cycles or cell health.
Is the 30A BMS sufficient for supporting a 1000W motor?
These safety features prevent the cells from catching fire or dying prematurely from poor charging. The package comes with a 42V 2A charger. This charger is slow for a 360Wh battery. It will take several hours to go from empty to full. You should look at other 36V battery options if you need faster charging.
Power Management
The power delivery of this battery is dictated by its internal management system. The 30A limit is the hard ceiling for what the electronics can handle. Most mid-drive motors rated 350W to 750W will work harmoniously with this pack. If you have a 1000W motor you are pushing the absolute limit of the hardware. The BMS might trip to protect the cells from overheating. You end up losing power halfway up an incline.
The inclusion of a USB charge port is a modern touch for riders. It allows you to charge your phone or GPS while you ride. This ensures your navigation stays alive while your bike is hungry. However using the USB port draws power from the battery. This reduces your total range slightly every time you plug a device in. The LED power indicator shows the remaining charge with four lights. This is better than guessing how much juice is left. It is not as precise as a digital volt meter but it gives a rough idea.
The 36V architecture is an older standard for ebikes. It offers less torque potential compared to 48V or 52V systems. This means the bike will feel less responsive on steep grades. It is best for flat terrain commuting or budget builds. You can find a Hailong power pack that fits this specific voltage and mounting style.
What Riders Say
The feedback loop for this specific LOCKBUS unit is incredibly thin. The listing shows no reviews and no rating at the time of research. This is a major red flag for any rider who values long term reliability. You are essentially the first test pilot for the quality of the cells and the BMS performance.

Current pricing and availability change often, so check the live listing before you order.
Who Should Buy This
This battery is for the rider on a very tight budget who needs a replacement for a dead 36V Hailong pack. It works well for short commutes where range is not the primary concern. If you have a small 250W or 350W motor this pack will serve you without much fuss.
You should NOT buy this if you have a high-performance 1000W motor setup. The 30A BMS is too weak for those high-draw demands. You should also avoid this if you plan on long distance touring or heavy mountain riding. The lack of reviews makes it a poor choice for someone who relies on their bike for daily transportation. If you want peace of mind and proven track records look elsewhere. You can find an affordable LOCKBUS 10Ah battery here if you are set on these specific specs.
Frequently Asked Questions
How much range can I actually expect from this 360Wh battery?
Your range will depend on factors such as your body weight, your motor power, and your riding route. For example, if you are traveling flat ground with a 250 W motor you may reach a range of 15 to 25 miles. Traveling hills or carrying heavier loads may reduce this range to below 10 miles. At 360Wh, this is a relatively small battery capacity compared to some modern ebike standards. Therefore, it is recommended that you anticipate shorter trips around your neighborhood, rather than extended day rides across town.
Is the 30A BMS strong enough for a 1000W motor setup?
The 30A BMS allows for a continuous draw of 1080 watts. A 1000W motor often pulls more than that during peak acceleration or steep climbs. The BMS may sense this overcurrent and shut down to prevent damage. This results in the motor cutting out right when you need power most. It is much safer to use this battery with a motor rated at 750W or lower to ensure the electronics do not overheat.
Is this battery truly waterproof for rainy conditions?
As mentioned previously, the manufacturer states that this battery case is waterproof. In general terms, waterproof means it can withstand rain showers. You should not ever attempt to submerge the battery in water or ride your bicycle through large puddles. Pressurized water will eventually force moisture past the seals allowing water to enter the battery and cause a short-circuit and subsequent failure. Always dry the battery thoroughly after riding in the rain.
What is the difference between the Hailong style and other batteries?
The Hailong-style refers to the way that the battery attaches to your bicycle's frame. Specifically, it refers to a sliding-style mount that attaches to the bottom tube of your bicycle via a metal bracket (or base). The base has holes drilled into it that match up with corresponding holes on your bicycle's frame downtube. The base is secured to your bicycle via two screws and can be easily removed by simply unscrewing them. Other types of mounts include attaching directly to a rear luggage rack or integrating directly into your frame.
The Hailong-style is popular among ebikers because it is simple to install/remove the battery from your bicycle for indoor charging purposes. Additionally, since it slides onto the bottom tube of your bicycle, you need to ensure that you have space for the mounting bracket on your frame (i.e., the holes need to line-up correctly).
