This battery costs 480Wh. That's roughly the same amount of energy contained within many entry-level downtube batteries. However, the Cefito 48V 10Ah, is a universal bottom bracket mount and therefore is not welded to any specific manufacturer's frame. Therefore when a generic replacement pack is listed at this price point the question shifts from "is this cheap?" to "what did they cut to make this cheap?" That sums up the entire review, and the answers may surprise you.
Therefore, I proceeded to evaluate each specification provided, each bullet claimed by the manufacturer, and each of the handful of genuine reviews on that webpage. Herein lies the true evaluation of this item.
Specifications and Build Quality
First, let's eliminate the obvious. In terms of specs, this is a 48V, 10Ah battery. To determine the Wh (watt-hour) we multiply voltage x ah = 480Wh. With regard to the significance of the 480Wh number, well, that really depends upon your needs as an e-biker. A general commuter (who doesn't carry a load, nor climb mountains) can reasonably achieve their round-trip commute on a single charge, and thus avoid carrying additional weight and bulk via an excessively large 20Ah brick.
This battery contains Grade-A lithium cells, and according to Cefito's specs is capable of surviving over 1000 charge cycles. I recommend taking the 1000 cycle number with a grain of salt. Every budget brand lists that number. Cycle numbers only represent real-world performance once you understand what constitutes a charge cycle. What truly represents a meaningful number is that these are lithium cells and not lead-acid bricks disguised as "48V" packs that some discount sellers may attempt to pass off as such. Furthermore, at this price point you are in lithium country for both weight savings and longevity.
In physical format this is a rectangular shaped bottom-bracket battery, which means you'll attach it to your downtube via generic rack or other mounting hardware you might have lying around. While it is possible to find universal style batteries, in my opinion this is one of the closest examples available.
I have identified two specifications to draw attention to. First, the connectors used on this battery include a T-plug and Cefito provides an XT60 to T-plug adapter with the purchase of this battery. The second item is a 5-pin connector located at the base of the battery. Note that while Cefito states this battery comes with a 5-pin connector and includes an XT60 plug for connection to your controller, the controller itself is not included. That is another example of why you should be aware of the term "universal." Keep in mind that a generic-style pack will require you to locate your own mounting hardware.
BMS and Safety Features
The BMS (battery management system) is the primary determining factor in evaluating a budget battery. The Cefito features a 30A BMS. The BMS protects against over-charge, over-discharge, over-current and shorts. These are the four standard protections you'd expect from any competent BMS.
Why does the BMS matter? Simply put, an ebike battery is an open container of stored energy sitting directly below your seat. If the BMS functions correctly then a faulty cell or short will be detected prior to creating a problem. Conversely, if the BMS is poor then you're rolling dice with a fire extinguisher as consolation.
The 30A rating indicates that this pack can deliver sufficient current to a motor without tripping too quickly on hills or aggressive acceleration. That's beneficial for commuters who prefer to accelerate aggressively from traffic lights.
Additionally there is a USB outlet built into the pack. Convenient for topping off your mobile device or small light while you're underway however location and whether it's always active would need verification. It's a small plus but useful for commuter packs.
For the money, I believe that the safety aspects of this pack are among the best things about it. The 30A BMS spec is something that can be held accountable. However, having a spec written on paper does not equate to functioning properly in real life. Currently there are only five reviews for this pack and therefore the real world safety track record is very thin. Consider that.
Range and Real-World Performance
Okay, let me be frank about this. There are only five reviews for this pack on Amazon currently and it has an average rating of 3.9 stars. That's not much data. A sample size of five can go either way, so treat that rating like a hint rather than verdict.
Positive reviews for this pack primarily center around value. Reviewers indicate satisfactory range for commuting purposes and easy charging using the supplied 2A charger as well as adequate construction quality relative to price. However, please consider that the supplied charger is only 2A. Therefore, you'll likely spend anywhere from 3 hours to half of a day waiting for a complete charge from empty using the included unit. Fast charging is also not available here. Plan accordingly.
Range will obviously vary based upon your bike configuration, your weight and how frequently you grab throttle vs. pedal-assist. A normal hub-motor commuter with moderate assisted-pedal usage should be able to obtain approximately 25-35 miles based upon terrain and throttle usage.
No manufacturer can provide your exact number because your weight and terrain usage etc., are all variables. Any figures manufacturers provide should be taken as rough guidelines only.
Low review count may be the greatest drawback regarding this product. Early adopter status comes with its own set of benefits, but you're betting on a product without any community history to back it up.

Who Does This Battery Suit?
If you have a dead or fading 48V pack on your ebike and wish to replace it with a budget-friendly option without selling one of your organs for brand name batteries then this battery is targeting you directly. Universal-bottom brackets mounts and a 30A BMS makes this a reasonable choice for anyone who wants to commute again without breaking the bank.
It's not suitable for extreme throttle riders, heavier riders, nor cargo-riders who burn through their capacity daily. Ten amp hours doesn't leave room for overhead and two amps takes forever to replenish. If you routinely use all your capacity per ride then larger capacity options on our battery comparison page will treat you better even though they cost more.
It's not suitable for you if you need drop-in fit for proprietary docking systems from specific brands. This is generic-pack style and thus requires you to source or fabricate your own mounting hardware yourself.
Frequently Asked Questions
Will the Cefito 48V battery fit my ebike?
It depends. The Cefito 48V battery is designed as a universal bottom bracket type pack, so it will fit frames with generic rectangular mounting areas and not proprietary mounts unique to individual brands. Measure your frame triangle and mounting hardware before buying this unit as "universal" does not guarantee it will fit every frame's triangle.
What connectors does this battery use?
The battery has t plugs and includes an XT-60 to t plug adaptor in packaging. The base plate on the battery also contains a five pin connector. Important to note: no controller comes with this pack, so ensure your existing configuration utilizes compatible connections.
How long does it take to recharge?
The charger that comes with this pack is a 2A unit, which is a relatively slow charging speed. It will take three hours or longer to completely recharge your ten amp hour pack. Good for overnight recharging, not ideal for quick top-off between rides.
What kind of mileage should I anticipate?
Typical range for a twenty-five (25) to thirty-five (35) mile commute distance on hub-motor commuters with moderate pedal assistance using a 48V 10Ah pack is generally expected. Terrain variations and extent of usage of throttle functionality will significantly impact your actual mileage.
Is the 30A BMS a legitimate safety feature?
Yes, the thirty amp BMS provides protection against over charge, over discharge, over current and short circuits. Those are all four types of protection you would typically expect from a quality bms.
What type of warranty does it come with?
Cefito offers a one-year warranty on this battery. That's standard for budget brands, therefore it's not really anything special regarding warranty coverage, however it does give some peace of mind for issues related to defects early on. If you're comfortable with that tradeoff, check current pricing on Amazon. And for more battery options with deeper feedback, head over to our blog.
