Compatibility and Fitment
The ebike industry continues to grow and evolve. A variety of different ebike brands are available. Many ebike manufacturers produce proprietary ebike batteries that are difficult to replace locally. Some ebike owners have had to replace the proprietary ebike battery (after having exhausted its energy storage capacity) because of its diminished capacity after a long period of usage and numerous charging cycles. ShunTongDa's Amazon listing for a drop-in replacement battery for Engwe folding ebikes could help save those consumers from potential future frustration.
The DCH-006/09 case style is common on folding ebikes. If you have an Engwe EP-2 Pro, Engine Pro, or Engine X ebike, this ShunTongDa battery will physically fit into your ebike. However, there are many other ebike brands that utilize this case style. Other examples include the Engwe Mate X, Bezior XF200, CMACEWHEEL RX20, and Lankeleisi X3000 Plus.
When buying this battery, simply make sure the connector configuration on the ShunTongDa battery is equivalent to the connectors on your original factory-installed battery. Also, verify the size of the two products. If you do not see this information in the seller's description, then you should reach out to them before making the purchase.
Aside from the connector configuration and size of the case, another important consideration is how the lock configuration works as a power switch. Typically, one turns the key to lock/unlock the battery. The electrical circuitry is active when locked and inactive when unlocked. There is no separate button required to activate/deactivate the power.
Prior to purchasing a new battery, pull the existing battery off of your ebike and examine the underside for a model number etched into the plastic. Examples of model numbers that would indicate you can buy a replacement from ShunTongDa include DCH-006, dch-009 or something very similar. Next to verifying the model number, you must also verify that the number of pins on the connector is the same as your original connectors.
The 48V version of ShunTongDa's 17.5Ah and 14Ah batteries differ in regard to their capacity. The 17.5Ah version has approximately 840Wh of capacity while the 14Ah version has approximately 672Wh. Both versions of this battery have sufficient capacity to equalize your original factory-installed battery in terms of total amp-hour rating. However, the 17.5Ah version offers a much greater increase in overall miles per charge than the 14Ah version.
Regardless of which version you opt for, both are designed to operate inside a 48V DC voltage environment and can be used with both mid drive and hub motors. When running at 48V, a controller module is not required. Rather it is just plug-and-play.

Specs and Build Quality
While building quality is obviously subjective and may depend on various factors, ShunTongDa's replacement batteries are generally constructed with injection molded ABS cases along with all of the required parts including connectors and mounting hardware. Consumers have indicated that the case of this product fits perfectly with OEM cases and that the slide rails remain secure during operation.
As specified in the manufacturer's documentation, the connectors on each battery are uniquely designed to be directly compatible with OEM connectors from Engwe for their ebike systems. Therefore, consumers will not be required to wire or add any adapters in order to connect their new ShunTongDa battery to their ebike system.
It is essential for consumers to recognize that if they have purchased an ebike from a retailer that utilizes a nonstandard configuration or have modified their ebike in a way that alters the position or type of their existing battery connectors, they may be required to install adapters or modify their wiring in order for the ShunTongDa battery to properly communicate with their ebike system.

BMS and Safety Features
Each of ShunTongDa's replacement batteries comes equipped with a built-in battery management system (BMS) capable of providing up to 30 amps of continuous discharge along with the following protective features:
Cell balancing Over discharge protection Short circuit protection Temperature cutoff Over current protection
For users that ride in extreme temperatures (either hot or cold), it should be recognized that ShunTongDa's BMS does include some temperature-related protective features. Nevertheless, it is suggested that users exercise caution when riding in extreme conditions. Extreme temperatures can result in permanent degradation of lithium-ion batteries or decrease their lifespan.
Who Is This Battery For?
Considering these points in practice, this product would be an excellent choice for customers that own an ebike mentioned previously and whose original factory installed battery has aged over time. This product may also be an option for customers whose ebike was delivered without a battery, or were unsuccessful in finding a compatible alternative. Regardless of why you need a replacement battery, we encourage you to consider taking a closer look at this product before deciding which product you want to purchase.
Please keep in mind that this product will not work properly if you try to utilize it with an ebike utilizing a standard downtube mount, shark mount or other proprietary case designs. Check measurements carefully before making a purchase. Additionally, please refer to our ebike battery comparison chart to view what other choices are available for your particular e-bike.
Frequently Asked Questions

Does it come with a charger?
Some configurations being offered by Amazon sellers will include a charger (usually either 2A or 3A) while others will not. As Amazon product descriptions and photos vary greatly among products, please verify this information before completing your purchase.
How do I know if my bike uses DCH-006 casing?
You can quickly determine whether your bike uses DCH-006 casing by removing your existing battery from your e-bike frame and looking at the model number etched or stamped onto the lower part of the plastic housing. Alphanumeric characters like DCH-006, dch-009 etc. indicate that you are dealing with compatible units.
Another method to establish compatibility is to compare the physical dimensions and slide rail configuration of your new ShunTongDa battery against your original factory installed battery.
What is the warranty?
This product is covered by a 1 year warranty from ShunTongDa, protecting against all manufacturing defects and premature cell failure resulting from normal use. Damage caused by accidents or breakage, water entry or submersion, and incorrect connections or electrical connections are exempt from this warranty. Although we understand that users typically prefer products from reputable manufacturers with a history of delivering top-notch products, in practice ShunTongDa's 1-year warranty is reasonable considering the affordable price of this product relative to OEM alternatives. We suggest retaining any receipts and documenting any problems you experience with your new ShunTongDa battery once you receive it.
Can this battery be used on other bikes?
If your other bike also uses DCH-006 or dch-009 casings, yes you can use this battery on your bike. Other examples of brands that utilize this case style include the Engwe Mate X, Bezior XF200, CMACEWHEEL RX20, and Lankeleisi X3000 Plus, though you should always verify the connector layout matches your original battery first.
