The SDTYYP 48V 12.8Ah is a 614Wh battery made by SDTYYP for folding electric bicycles, such as the Lectric XP and Jasion EB7. Because SDTYYP is a manufacturer of replacement batteries, this battery is designed to be installed directly into the downtube or frame cavity of a compatible folding ebike, whereas universal batteries must be installed using an external mount or bracket. The battery comes with a 30A BMS and a 54.6V 2A charger, as well as an anti-theft locking mechanism to prevent removal of the battery from the frame of the ebike. According to the manufacturer, the battery is suitable for motors ranging from 250W to 1000W.
Because the SDTYYP 48V 12.8Ah has a capacity of 614Wh, this battery is suitable for a wide range of applications, including daily commuting and casual riding on a folding ebike. The physical characteristics of this battery include a length of 430mm, a width of 100mm, and a height of 43mm, as well as a weight of 3.38 pounds, which is significantly less than many other batteries on our comparison table. The 30A BMS is rated for 30 amps and is suitable for protecting motors up to 1000W. In addition, the battery has a sealed housing that protects against water and sand, allowing users to ride in various weather conditions without fear of damaging the battery.
Specs and Value
The primary specifications of the SDTYYP 48V 12.8Ah are 48V nominal voltage and 12.8Ah of capacity, resulting in a total of approximately 614Wh of stored energy. As a result, the SDTYYP 48V 12.8Ah falls in the middle range for 48V batteries, as they offer enough capacity for most daily commutes and weigh very little compared to other folding frame batteries.
Physical specs
The battery measures 430 x 100 x 43mm and weighs 3.38 pounds. These dimensions were designed to fit inside the frame cavity of a compatible folding ebike, such as the Lectric XP and Jasion EB7. The slimmer profile of the battery allows it to be easily integrated into the frame without adding unnecessary bulk outside of the frame, which is a significant advantage for folding bikes that must be folded into a small shape for storage and transportation.
The battery comes with a 54.6V 2A charger that will take around 6 to 7 hours to charge the battery from completely empty to a full charge. This is a typical charging time for a 2A charger for a battery of this size. The fully sealed housing provides protection against sand and water, and the anti-theft locking mechanism allows you to secure the battery inside the frame.
BMS and motor range
The 30A BMS protects against overcharging, over-discharge, overcurrent and short circuits. On a 48V system, 30 amps results in a maximum theoretical output of 1440 watts, which gives plenty of room for the stated motor compatibility range of 250W to 1000W. The 30A BMS is a common rating for a battery in this capacity range and will likely handle the power requirements of the motors used in most folding ebikes.
Although SDTYYP lists the battery as containing high quality lithium-ion cells, SDTYYP does not list the specific brand or chemistry of the cells. For a replacement battery in this price range, the 30A BMS and sealed housing provide a reasonable level of protection and build quality.
Form Factor and Compatibility
The SDTYYP 48V 12.8Ah is unique among the batteries on our comparison table in that it is a built-in frame battery, designed to insert into the frame cavity of specific folding ebike models. The primary compatible ebikes listed are the Lectric XP and Jasion EB7, which are both popular folding ebikes that use a built-in frame battery. The built-in design is important for folding ebike owners, since it preserves the ability to fold the ebike.
Before purchasing, check if your specific ebike model uses the same internal battery dimensions as either the Lectric XP or Jasion EB7. Although ebikes within the same model line may use the same battery form factor, ebike manufacturers often change the form factor between production years. To confirm that the 430 x 100 x 43mm dimensions match your ebike's frame cavity, measure your existing battery or measure the frame cavity of your ebike. Also check that the discharge connector type is compatible with your bike's controller.
Real-World Range
The 614Wh capacity of the SDTYYP 48V 12.8Ah is large enough to support most daily commuting needs for a folding ebike. Assuming a moderate amount of pedal assistance on flat terrain, the battery should allow you to travel around 18 to 28 miles on a 500W motor before needing to recharge. If you are using a 750W or 1000W motor and apply more throttle input, you can expect the battery to last around 10 to 18 miles. For the average commuter who travels 5 to 10 miles to and from work, this battery should be able to complete the round trip on a single charge.
The 614Wh capacity is not ideal for long distance travel, however, most folding ebike owners do not intend to ride long distances. Most ebike owners plan to use their ebikes for short urban commutes, last-mile transportation, or recreational rides. For these types of riding, the 614Wh capacity is a good balance between range and weight. Check our comparison table to compare the SDTYYP 48V 12.8Ah to other 48V batteries on price per watt-hour.
What Amazon Reviewers Are Saying
The SDTYYP 48V 12.8Ah does not have any customer reviews on Amazon as of the date of this writing. The listing for the battery was first added to Amazon in July 2025, and thus there has been insufficient time for customers to post reviews regarding the actual performance, installation, and durability of the battery.
SDTYYP is a lesser known brand in the ebike battery market, and without the benefit of customer reviews, potential buyers of the battery will be relying solely on the technical specifications and description provided in the listing when making a buying decision. The lack of reviews is not necessarily a red flag, as many replacement batteries for specific bike models have smaller audiences and take longer to accumulate feedback.
If you prefer to purchase a battery with a proven track record of customer feedback, you may want to wait until reviews are posted or consider alternative options. Check our battery comparison table for other 48V folding ebike batteries with a larger body of customer feedback.
Who Should Buy This
The SDTYYP 48V 12.8Ah is designed for owners of the Lectric XP and Jasion EB7 folding ebikes who need a replacement battery that fits inside the frame cavity. The built-in form factor of this battery preserves the folding feature of the ebike while providing 614Wh of usable capacity for daily commuting and casual riding. The 30A BMS and sealed housing of the SDTYYP 48V 12.8Ah provide standard levels of protection for motors up to 1000W.
In addition to being a direct replacement for the Lectric XP and Jasion EB7, the SDTYYP 48V 12.8Ah is one of the lightest batteries on our comparison table for its size. At 3.38 pounds, this battery is light enough to be carried on a regular basis, especially when considering that the battery fits inside the frame of a folding ebike and does not require the use of an additional bracket for mounting. The anti-theft lock adds security for riders who leave their bikes parked in public areas.
This battery is not intended for riders of ebikes that require a universal battery and have an external mounting bracket. In addition, the lack of customer reviews and the fact that SDTYYP is a relatively new brand in the ebike battery market means that buyers are assuming a degree of risk. However, for owners of the Lectric XP and Jasion EB7 who need a direct replacement battery at a competitive price, the SDTYYP 48V 12.8Ah is certainly worth reviewing. Compare it against other options on our battery comparison table.
