The SDTYYP 48V 14Ah is an integrated downtube battery that replaces a specific set of ebike models such as the Aventon Pace 350, Pace 500, and NCM Moscow. The 672Wh capacity and aluminum alloy casing make this battery a viable option to install inside those ebikes that utilize the Reention Dorado Plus battery housing. If your original battery has started to lose performance and you want a compatible replacement, then this is one of the options you may wish to consider on our comparison table.
SDTYYP is a brand name that appears throughout various ebike replacement batteries, especially for popular ebike models such as the Aventon and NCM lines. They have multiple ebike replacement batteries listed in the 48V category and this particular 14Ah model is targeting a group of riders who require an exact fit replacement versus a universal battery. The listing is quite clear that this is an integrated battery and the compatibility of this battery is strictly based on whether the size and appearance of this battery will match your current battery.
Specs and Build Quality
The specifications of this battery are straightforward. 48V is the nominal voltage, 14Ah is the capacity, and the total amount of energy stored in the battery is 672Wh (48 x 14 = 672). 672Wh is a respectable amount of stored energy for a 48V ebike system and should give you sufficient range for daily commuting and recreational riding. The battery itself weighs 11 pounds which is fairly normal for an integrated downtube battery with this capacity. The dimensions of the shipping box are 15.35 x 4.13 x 2.56 inches and give you a general idea of the overall size of the battery.
Physical specs
The physical dimensions of the battery are 390 x 104 x 65mm (or approximately 15.4 x 4.1 x 2.6 inches) which is crucial information since this is an integrated battery that needs to fit inside the battery compartment of your ebike with perfect precision. The housing is constructed from aluminum alloy and is a step up from the plastic housing used on many of the lower cost ebike batteries. Aluminum provides better heat dissipation and tends to feel more solid and durable when mounted. Included with the battery is a safety lock to keep the battery securely fastened to the frame and the charging port utilizes a DC connector.
The charger provided is a 54.6V 2A charger, which is the correct charge voltage for a 48V 13S lithium-ion battery. SDTYYP states it will take 5 to 7 hours to charge the battery from empty to full and that is a typical duration for a 2A charger on a battery of this size. The charger has nothing unique to offer in terms of charging speed, but it will get the job done for either overnight charging or for topping off the battery during the day. The listing also mentions a "smart" charger but does not describe anything that would indicate the charger is smarter than standard chargers, although it does mention the standard feature of auto-shutoff when the battery is fully charged.
BMS and motor range
SDTYYP lists the motor range for this battery as being from 250W to 700W. While that is a relatively conservative rating, given that some other batteries in this price point claim to support 1000W motors, it is actually consistent with the intended use case of this battery. The Aventon Pace 350 has a 350W motor and the Pace 500 has a 500W motor and therefore 700W provides a reasonable buffer above both intended use cases.
The BMS details are not mentioned extensively in the listing. They do state that their quality testing demonstrates that 80 percent of the capacity will remain after 800 charge cycles, which is a realistic expectation for lithium-ion cells. You will commonly see competitors making claims of 1500 or more cycles and therefore SDTYYP is actually refreshing by setting realistic expectations of 800 cycles. Based on 800 cycles of regular use, you can anticipate 3 to 5 years of service life before the battery begins to noticeably lose range.
Form Factor and Compatibility
This is where the SDTYYP 48V 14Ah becomes specific and where you need to pay close attention. It is an integrated downtube battery, which means it mounts directly inside the ebike frame compartment instead of mounting on the outside of the ebike frame via a bracket. The listing specifically identifies the Aventon Pace 350, Pace 500, Pace 1.0 MTB, Scrappeur MXC, and the NCM Moscow as compatible models. All of these ebikes use a Reention Dorado Plus style battery housing.
The critical item that SDTYYP stresses is that compatibility will only occur if the size and appearance of this battery match your current battery exactly. Because this is an integrated battery, it is not a universal battery like a Hailong or Shark battery. The dimensions, connector location, and rail system all need to match perfectly. If your bike utilizes the Reention Dorado Plus battery housing and the dimensions of your current battery are the same as the 390 x 104 x 65mm dimension of this battery, then you should be fine. However, if you are not 100 percent certain, please verify the dimensions of your current battery before ordering.
The aluminum alloy housing gives the battery a very clean and factory-looking installation. It will not protrude from your ebike frame like an aftermarket accessory and the integrated nature of this battery means you do not have to deal with any external mounting brackets or exposed cabling. The included safety lock secures the battery to the frame while you ride and allows you to remove the battery for charging indoors.
Real-World Range Estimates
Based on the 672Wh of energy that is stored in this battery, you should be able to achieve a reliable range for most riding conditions. For example, on an Aventon Pace 500 equipped with a 500W motor, moderate pedal assist on flat terrain should yield ranges of approximately 25 to 40 miles per charge. On the other hand, if you reduce the motor to a 350W motor like the Pace 350, you may be able to increase your range to 35 to 50 miles with conservative pedal assist usage.
Of course, those estimated ranges will be reduced if you are relying heavily on the throttle, riding in hilly areas, or carrying additional cargo. Full throttle on a 500W motor through mixed terrain may result in ranges of 15 to 25 miles, which is still acceptable for short commutes and errands. The 14Ah capacity of this battery is very close to what many ebike manufacturers originally ship with their bikes and therefore you should expect the same range characteristics from the SDTYYP 48V 14Ah.
If you plan on doing daily commutes of 10 to 15 miles round trip, this battery should be more than capable of handling the commute. Charge it overnight and you will be ready to go the next morning. Check how it compares to other 48V options on our comparison table.
