This is a 48V 1200Wh folding style ebike battery. The pack is designed to hold a significant amount of energy, enough to let you ride much longer distances than a standard 10Ah or 13Ah pack. The folding style allows the battery to sit on a bracket mounted to the bottom of your ebike's frame rather than being tucked inside it. It also has a locking system with a key to keep it secure when parked. The included bracket and XT60 connector make installation about as straightforward as it gets for a folding battery this size.
If you've been browsing the ebike battery comparison table looking for something with serious range at a reasonable price, this one earns a look. The seller's customer service gets consistent praise, with multiple reviewers mentioning that SEENRONGYUAN reached out before shipping to confirm compatibility. The battery performs well according to reviews, and most buyers were satisfied with their purchase.
Specs and Build
The battery comes with a mounting bracket and connectors. The bracket attaches the battery to the bottom of the ebike frame. The dimensions of the battery are 14.37 inches by 5.12 inches by 3.43 inches. The weight is approximately 11 pounds, so it's not the lightest option out there but it's reasonable for the capacity. The case is a hard plastic housing typical of folding batteries, with a portable handle on top that makes carrying it convenient.
The built-in security lock keeps the battery secured to the frame and doubles as theft deterrence when you park. You get two keys with it. The pack uses a 30A BMS that handles overcharge, over-discharge, overheating, and short circuit protection. SEENRONGYUAN rates it for motors from 250W up to 1000W. The cell chemistry is lithium-ion with a 25 amp-hour capacity at 48 volts nominal, giving you 1200Wh of total capacity.
Range and Real-World Performance
At 1200Wh, this battery delivers serious range. On a typical ebike setup with a 750W motor, you're looking at 30 to 45 miles depending on terrain, throttle usage, and rider weight. With a 500W motor and mostly pedal assist, you could stretch past 50 miles. That's enough for all but the longest commutes or weekend adventure rides.
One thing multiple reviewers mention is that the battery sits low on the frame, which helps handling compared to top-tube or rack-mounted packs. Some users reported the battery performed well even after heavy use, maintaining consistent power output throughout their rides. Others found they did not have to charge often, going a whole week without needing a recharge depending on their commute distance. That kind of real-world range is what makes a 25Ah pack appealing in the first place.
A few buyers mentioned the battery is slightly taller than expected, which could be an issue if your frame has a tight battery compartment. If your bike features a recessed frame or tube for the pack, it could present an issue as it sticks out from under the seat. Measure your available space before ordering.
What Amazon Reviewers Are Saying
This ebike battery receives an average rating of 4.3 stars based on 19 total reviews. Buyers generally feel this battery delivers solid performance for its price.
The positives from buyers:
The seller's customer service gets consistent praise. Several reviewers wrote about receiving emails before shipment confirming compatibility. That kind of proactive support is rare at this price point and adds peace of mind. Battery performance is strong across the board, with users reporting good range, steady power delivery, and simple installation. Multiple reviewers appreciated how lightweight it is compared to lead-acid and generic lithium-ion packs they had used before. One buyer called it a great service experience and said the battery fit perfectly.
The negatives from buyers:
The main downside is sizing. A number of reviewers noted concerns about fitment. Specifically, the battery may be taller than your original pack, particularly if your bike has a recessed battery compartment rather than a universal mounting bracket. The included bracket works fine for frame-mounting, but if you were hoping for a drop-in replacement inside your frame, double-check the dimensions.
Who Should Buy This Battery
This battery makes sense for riders who need maximum range without spending top dollar. The folding form factor works great for bikes with frame-mounted brackets, and the included hardware makes installation straightforward.
Good for:
- Commuters riding more than 25 miles per day
- Folding ebikes with external frame-mounted brackets
- Riders needing a removable pack for security and charging convenience
- Anyone upgrading from a smaller pack who wants to double their range
- Bikes lacking sufficient internal space for a larger pack
Not great for:
- Tight frames where packs cannot fit below 14 inches
- Ultra-light builds where 11 pounds is too much weight
- Anyone who needs specific form factors like downtube, Hailong, or Shark
Frequently Asked Questions
