It may be better to have a reliable Battery like this 36V 20Ah ebike Battery arrive at your doorstep. With Twenty amp hours on a thirty-six volt system you can access 720 watt hours of usable power, which is far more than the paltry seven ah (twenty-one watt hour) Battery that was mounted on your bike from the factory. The pack includes a USB port for charging your phone or other devices during the ride and comes with an anti-theft lock, something that many lower cost packs lack.
Do not buy until you understand that currently this product listing has zero reviews. Therefore, the only thing keeping you from purchasing this pack is the fact that it has never been reviewed. As such, i will reference the Specs provided by the manufacturer, and indicate any unknown variables as we move forward.
Specs and Build Quality
Capacity is where the numbers start. You get 720 watt-hours using a 36-volt and 20 amp-hour configuration. Depending on the level of assistance used, on average, you should be able to travel approximately forty-five miles per hour. However, when traveling uphill or in windy conditions you may get less mileage.
Dimensions are fourteen-and-a-half by three-and-three-quarter by four-and-a-half inches. Or in metric terms 37.6 by nine by eleven-and-two-tenths centimeters. The pack weighs nine-and-two-tenths pounds. While not lightweight, these specifications make the Battery suitable for mounting to a rear rack or securing in a bicycle frame triangle bag.
The ABS plastic case of the Battery provides both shock resistance and water proofing. This is exactly what you want when the Battery resides on the outside of your bike and endures exposure to weather elements and vibration on each ride.
The lead wire has an XT60 connector at the end. This is actually an advantage. XT60 connectors are well-established in industry use, they are highly reliable and capable of carrying a large amount of current. Additionally, most higher-end controllers and chargers utilize this type of connector. If your existing bike utilizes an XT60 plug then you can simply swap-in this new Battery and continue to utilize your original wiring harness. If your bike has a different plug type, you will either need to purchase an adaptor or add some soldering capabilities to complete the connection.

BMS, Safety, and Design Features
On the inside of the ABS casing is a BMS (Battery management system) rated for thirty amps of continuous output. In terms of 36-volts systems having a thirty amp BMS is important because it enables the pack to provide sustained output to motors ranging in power output from one hundred to one thousand watts. The BMS is responsible for controlling all functions associated with electrical Safety including. overcharging, over-discharging, short-circuit detection, and thermal protection. As such, the electronic components in this pack take care of ensuring that the internal cell(s) are protected from damage caused by excessive electrical stress.
Another unique feature included with this Battery is a USB charging port located on the exterior of the pack. Although it cannot rapidly recharge your smartphone or tablet, it can serve as a convenient method for providing additional power in case your device's Battery becomes depleted during a long ride.
Finally, there is an optional anti-theft lock that can be applied to secure the Battery in place. Since the theft rate of bicycles continues to rise as cycling increases in popularity, the inclusion of this anti-theft mechanism is welcome. This lock serves as a deterrent to those thieves who are interested in quickly stealing a pack from a bike. It is not intended to replace a true lock designed for securing bicycles however.
Range and Real-World Performance
I wish to provide a fair perspective regarding expected Range. Based upon the characteristics described above, you can reasonably expect to achieve ranges from approximately 40-55 miles based upon factors such as. weight, terrain, and speed of travel when utilizing moderate levels of assistance. However, if you consistently maintain maximum torque input to your motor throughout your entire ride you will likely realize significantly reduced Range. Conversely, maintaining steady speeds at low torque inputs will enable you to maximize the achievable Range. As such, there is sufficient "head room" available within this pack to allow you to make extended trips with minimal requirement for additional recharging en route.
Therefore, this Battery will appeal primarily to commuters who desire to minimize their need for frequent recharging, trikes/tricycles requiring greater payloads than smaller units, and electric scooters experiencing rapid depletion due to excessive usage.
As previously mentioned, compatibility with existing 36-volt systems is typically acceptable since they utilize similar configurations. Check your motor and controller specifications however to confirm compatibility with this pack's voltage requirements. If your bike employs a 48-volt system, this Battery is not appropriate for your needs.
In addition to compatibility considerations regarding your e-bike's existing configuration, another critical consideration is matching the pack's discharge capability to your e-bike's motor characteristics. Specifically, since this pack is rated at thirty amps continuous output, it supports motors within a power output Range of 100-1000 watts. Thus, if you plan on operating your e-bike aggressively and/or have selected a high-wattage controller for performance purposes, you will exceed the recommended load ratings specified by the manufacturer.
Who Is This For?
This pack is suitable for several distinct groups of users:
- commuters who seek multi-day Range without needing to carry secondary packs.
- trike/tricycle operators conducting extended loop routes.
- scooter owners that experience frequent exhaustion of their existing small packs.
Ultimately, this is a viable option for anyone seeking a durable thirty six volt workhorse with a sealed casing and reasonable BMS capabilities at an affordable price point. check out the pricing options for this pack here.
However, there is an undeniable risk involved with purchasing this product. Currently, there are zero reviews for this product from customers on amazon. Therefore, no independent verification exists for any claims made by the manufacturer. While that does not necessarily mean that the Battery is defective in any way - it merely means you are assuming some risk of purchasing an unproven unit. If you prefer a proven unit with documented performance and reliability, consider investing in a more established brand name pack instead.

Frequently Asked Questions
What size battery is this, and how many watt hours?
This is a 36 volt 20 amp hour pack, which works out to 720 watt hours of usable capacity. On a 36 volt system that is roughly double what the tired little factory packs on entry level commuter bikes carry, so it gives you real room to stretch a ride.
Will it work with my 48 volt bike?
No. This pack is built for 36 volt systems only. If your controller and motor are wired for 48 volts, this battery will not be compatible and you should look at a 48 volt pack instead.
What connector does it use?
The lead wire terminates in an XT60 connector. That is a common, high current connector used across the ebike industry, so if your existing harness already uses XT60 you can plug this pack straight in. If your bike uses a different plug, you will need an adapter or a bit of soldering.
Does the USB port really charge my phone?
It can top off a phone in a pinch, but do not expect fast charging. The USB port is a convenience for emergency juice on a long ride, not a replacement for carrying a proper power bank.
How long will it take to charge?
There is no bundled charger, so charge time depends on the charger you already own. With a typical 2 amp 36 volt lithium charger, expect roughly eight to ten hours from empty. A larger charger will cut that down, but keep the current within what the BMS is rated to handle.
Is it risky to buy with zero reviews?
It is worth being honest about this one. With no customer reviews yet, there is no independent feedback confirming the claimed specs and long term durability. The BMS protections and ABS shell are reassuring on paper, but you are taking a small leap of faith on an unproven listing. If you would rather have documented performance, a more established brand with a track record may be the safer call.
