SHEWAIHE is just another one of those many Amazon battery manufacturers creating products toward the lower-end of the cost scale when it comes to buying batteries. They sell their 48V 13Ah pack for under 160 dollars, providing 624Wh of usable capacity at about 25 cents per Wh. That makes them one of the lowest-cost-per-Wh options in the 48V category.
The battery is approximately 14.37 x 5.12 x 3.43 inches and weighs approximately 10.8 lbs. That provides a nice, compact, and space-saving design, especially when compared to other 48V systems of equal capacity. The smaller footprint helps with fitting the battery into tighter bike frames where larger packs simply won't go.
Specs and Build Quality
This is a 48V nominal battery with a capacity of 13Ah and a total energy output of 624Wh. The product was designed using a downtube configuration style and features a top-mounted discharge outlet. Why is this important? Many other configurations direct the outlet down through the center of the battery and since the base plate of the battery will be oriented differently depending on how it is mounted, this may present additional challenges in terms of routing wiring to the motor.
Important specifications from the seller include:
- Nominal voltage: 48V
- Actual capacity: 13Ah (624Wh)
- Continuous BMS rating: 40A
- Dimensions: 14.37 x 5.12 x 3.43 inches
- Weight: 10.8 lbs.
- Peak motor support: 0-1000W
- Outlet location: top mounted
The weight is very acceptable considering the amount of capacity inside the battery. On average a 48V 13Ah battery weighs 9-12 lbs. consisting of cells and case material. This battery weighs right in line with standard lithium-ion ebike packs.
In addition to the battery itself, the package also includes a mounting bracket, a charger, two wrenches, and six screws. The mounting bracket attaches directly to either the seat tube or frame rail of your bike, while the battery locks into place with a provided key.
BMS and Product Features
SHEWAIHE included a 40A BMS with this product. It offers overcharge, overdischarge, overcurrent, and short circuit protection. Since the BMS is rated for 40A maximum, it should be able to provide full motor current (about 1920W) during operation without cutting off the motor (assuming you are running no more than a 1000W motor), thus allowing for some headroom.
The battery is secured to its mounting bracket via a keyed lock. While it does not appear to be overly secure (it appears to be a simple tumbler lock), it likely deters casual thieves.
As mentioned earlier, the outlet for charging and discharging is located at the top of the battery. As such, if your bike's frame rails direct wires from below the bike frame, check that the orientation of the battery will allow easy cable routing prior to placing an order.
Feedback from Other Buyers
Currently, the SHEWAIHE 48V 13Ah has a total of two reviews with an average rating of 4.2 stars. In addition to being limited by small number of reviewers, they did indicate that upon arrival and after charging, the batteries worked as expected.
Feedback concerning the compactness of the product were noted as positives by reviewers. Overall, the dimensions should accommodate normal mountain bike and cruiser frames fairly easily. Unfortunately, there have been no negatives expressed by reviewers yet.
It is worth mentioning that limited reviews are a consideration in your overall evaluation. SHEWAIHE is a well-known manufacturer within Amazon and they have several battery offerings currently listed. Therefore, based on their existing product offerings, other products from SHEWAIHE have received feedback from more customers over time.
Who Would Benefit Most From This Battery?
Based on pricing alone, this is likely going to appeal to users building budget-friendly 48V systems where capacity becomes secondary to initial investment costs. At around 25 cents per Wh, it is hard to find a cheaper way into 48V power for a commuter or light trail build.
Good matches:
- Commuter bikes using a hub motor with capacities ranging from 500W to 1000W
- Users seeking 15-25 miles of travel distance on each charge cycle
- Replacement batteries for existing stock 48V batteries
- Small frame triangle designs where larger packs do not fit
Not ideal for:
- High powered builds requiring over 40A steady state draw
- Users desiring more than 30 miles of travel range
- Those who desire verification of user experiences from a large sample
- Bicycles utilizing bottom-mounted discharging orientations
The compact size and light weight make it a solid option for commuter bikes where you do not need massive range. 624Wh covers most daily commutes with margin to spare. Riders who charge at work or overnight will find the capacity sufficient for round-trip commutes up to 20 miles each way.

Frequently Asked Questions
Will this battery fit my bike frame?
The dimensions are 14.37 x 5.12 x 3.43 inches. Measure your bike's triangle or mounting area before ordering. The top-mounted discharge port means cable routing may differ from bottom-discharge packs. This is a key consideration for riders with existing wiring setups that assume a bottom port.
What size motor can I use?
SHEWAIHE rates it for 0-1000W motors. The 40A BMS provides headroom above the motor rating. A 1000W motor at 48V draws about 21A continuous, well within the 40A limit. Even a 1500W motor running at 31A would have headroom.
How long does charging take?
The included 2A charger takes approximately 6-7 hours for a full charge from empty. A higher-amp charger (4A+) will charge faster but would need to be purchased separately. Overnight charging with the included unit is the most convenient approach for most riders.
What kind of range can I expect?
624Wh at typical ebike consumption of 20-25Wh per mile gives roughly 20-30 miles. Hills, rider weight, pedal assist level, and wind all affect real-world results. Riders using higher assist levels continuously will see closer to 15-18 miles.
Does it come with a mounting bracket?
Yes, the kit includes a battery holder bracket, charger, two wrenches, six screws, and two keys for the lock. Everything needed for installation is included in the box.
Is this battery compatible with 52V systems?
No, it is a 48V nominal pack (full charge 54.6V). Using it on a 52V system designed for 58.8V full charge could damage the battery or controller. Stick with 48V components for this battery.
