The UAZ 36V 15.6Ah is a Hailong-style ebike battery with a capacity of 561.6Wh that fits into a classic downtube-mounted battery shape. It is part of the UAZ multi-voltage product line that offers batteries in 36V, 48V, and 52V. This particular model is the 36V 15.6Ah version with a 4-pin connector. Riders who are seeking a 36V battery replacement, or who wish to build a conversion project, will find that 561Wh of energy is ample to satisfy many applications. You can compare it with other 36V packs on our comparison table to see how it stacks up in terms of price per watt-hour.
UAZ is a relatively new name in the budget ebike battery market. Although they are not a well-known name to the general public, they produce a variety of batteries across multiple voltages and capacities under the same product listing format. This 36V 15.6Ah version is sold as a complete kit with a charger, a mounting bracket, keys for the lock, and the battery itself. You do not need to purchase additional items to install and begin using the battery. The listing claims a 40A BMS, which is on the higher end for a 36V pack and would theoretically support motors up to 1000W without any issues.
Specs and Build Quality
The battery specifications are 36V nominal voltage and 15.6Ah of capacity, providing a total of 561.6Wh of energy storage (36 x 15.6 = 561.6). The 561.6Wh of energy storage is a large capacity for a 36V battery and is greater than nearly all 10Ah and 12Ah versions of 36V batteries available today. The battery weighs 10.8 pounds according to the bullet points, though Amazon's tech specs list the item weight at 8.5 pounds. Both weights are reasonable for a battery of this capacity.
Physical specs
The physical dimensions are listed at 14.47 x 3.74 x 4.17 inches in the bullet points, which is a standard Hailong housing size. The battery will likely fit onto most downtube mounts that accommodate the Hailong configuration, though it is recommended to verify the frame clearance prior to ordering. The battery slides into a metal mounting plate that attaches to the downtube with slotted holes, allowing the user to adjust the position to avoid frame obstructions. UAZ includes mounting screws and two keys for the built-in lock mechanism.
Some features that are not typically found on less expensive ebike batteries are included on the UAZ 36V 15.6Ah. A series of LED lights located on the top of the battery indicate the level of charge remaining. While some ebike displays may not accurately indicate the remaining battery life, this feature will allow users to estimate how much time remains until the battery needs to be charged. Additionally, a USB charging port is provided, enabling you to charge your mobile device while riding. The charging speed will be limited, but it will maintain a level of charge sufficient to prevent the device from dying on longer rides. The battery housing contains water-resistant seals to protect against moisture, including rain and splashing, though the battery is not designed to be submerged in water.
BMS and motor range
According to the listing, the battery includes a 40A BMS, which is a relatively high current rating for a 36V battery. At 36V and 40A continuous discharge, the battery can theoretically support up to about 1440W of power output. In practical terms, the 40A BMS will be able to supply power to motors up to 1000W, providing a substantial margin of error for users of 250W to 750W commuter setups, or those converting their bikes to 1000W motors.
Standard protection mechanisms for the BMS include overcharge protection, over-discharge protection, short circuit protection, and over-temperature protection. UAZ states that the cells within the battery will withstand 1500 or more charge cycles, although this estimate is somewhat optimistic for lithium-ion cells. Users should plan for 800 to 1000 charge cycles before experiencing a noticeable reduction in capacity. Based on these estimates, the battery should last for 2 to 3 years of normal usage.
Form Factor and Compatibility
The Hailong configuration is perhaps the most widely accepted battery form factor in the ebike community. The configuration is relatively compact, and the slide-in design enables the user to easily access the battery for indoor charging. The UAZ 36V 15.6Ah utilizes the well-established Hailong configuration with a locking mechanism to secure the battery during rides and enable quick removal for charging.
Installation is relatively simple. Install the metal mounting plate to the downtube of the frame with the included hardware, insert the battery into the plate, and lock it in place using the key provided. The slotted mounting holes in the plate allow the user to adjust the position of the battery to suit the unique requirements of their frame. The battery uses a standard 4-pin discharge connector and an XT60 output, providing two possible connections depending upon the type of connector utilized by the controller. The 4-pin connector is commonly used in 36V ebike systems, but the pin arrangement may differ among manufacturers. Contacting the manufacturer or verifying compatibility with your controller prior to ordering is advisable.
UAZ does not list specific bike brand compatibility in the listing, instead describing it as suitable for commuter and off-road ebikes with 36V systems. They do mention a 24-hour response time for compatibility questions, which suggests they are willing to help you figure out if it will work with your particular setup. If you are building a conversion or looking for a replacement, the Hailong form factor gives you a lot of flexibility since it works with most standard downtube mounting positions.
Real-World Range Estimates
UAZ claims 20 to 45 miles per charge under moderate use conditions. The actual range depends heavily on your motor wattage, rider weight, terrain, and how much throttle versus pedal assist you are using. With 561.6Wh of capacity, you have a solid energy reserve to work with.
On a 250W to 500W motor with moderate pedal assist on relatively flat terrain, expect somewhere in the 30 to 45 mile range. That is enough for most daily commutes with energy to spare. If you are running a 750W or 1000W motor and relying more on throttle, especially on hilly terrain, realistic range drops to maybe 15 to 25 miles. The good news is that 561Wh gives you noticeably more range than the smaller 10.4Ah version of this same battery, which only stores 374Wh. That extra 50 percent capacity makes a real difference on longer rides.
The included charger takes approximately 5 to 7 hours to fully charge the battery from empty. For riders who want to see how the UAZ 36V 15.6Ah stacks up against other batteries in terms of price per watt-hour, check the comparison table.
What Amazon Reviewers Are Saying
This is a relatively new listing on Amazon, first available in October 2025, and at the time of writing there are no customer reviews posted. That means there is no real-world feedback to draw from regarding long-term reliability, actual range performance, or how well the battery holds up over time. The absence of reviews is not necessarily a red flag since newer products simply have not had time to accumulate feedback, but it does create uncertainty for potential customers.
UAZ does have reviews on their other battery variants (the 36V 10.4Ah version under a different ASIN has a few reviews with mixed feedback), so the brand is not completely unknown. But for this specific 15.6Ah variant, you are essentially an early adopter. UAZ offers a 3-month replacement warranty and 12 months of technical support, which provides some safety net if the battery arrives with issues or develops problems early on.
Who Should Buy This
The UAZ 36V 15.6Ah makes sense for riders who operate a 36V ebike system and require a larger capacity battery than the standard 10Ah packs. The 561Wh of energy contained in the battery will provide ample range for users operating a 250W to 500W motor with moderate pedal assistance on relatively flat terrain. The range may be reduced for users operating a 750W or 1000W motor with heavy throttle input on hilly terrain. The complete kit supplied by UAZ includes a charger, mounting bracket, mounting screws, and two keys to secure the battery to the frame. The inclusion of a USB charging port and the LED power indicator are welcome additions that enhance the overall functionality of the battery.
The lack of any customer reviews is something to weigh carefully. You are relying on UAZ's specs and claims without independent verification from other buyers. If you are comfortable with that trade-off and the Hailong form factor fits your frame, the UAZ 36V 15.6Ah is worth considering.
