You've got the DYMOZYNE 36V 12Ah 432Wh replacement pack battery. With all these features, it should come as no surprise that this DYMOZYNE pack has a lot of potential as a cheap alternative to other 36V ebike batteries. At 23 cents per Wh, this battery is likely one of the most affordable options on Amazon for a 36V battery, sitting near the top of the ebike battery comparison table for value. But being cheap is nice, it isn't everything. In fact, many times cheap simply means low quality, and there are certainly comments in the reviews section from customers who would agree with that.
Specs and Build
This pack is made of a PVC case and contains 432Wh (36 volts x 12 amps). The case itself is roughly 7.9 inches wide, 3.5 inches deep, and 2.7 inches tall. Weighing around 2 to 2.5 kilograms, it's large enough to hold a decent charge yet light enough to store in a bag or under the seat without adding too much weight. The BMS on this pack is designed to allow you to drive motors up to 1000 watts. However, several reviewers noted that the BMS didn't perform as well as they expected. While no one reported that the BMS failed during testing, there was at least one report that stated the BMS caused the pack to shut off prematurely.
The battery uses an XT60 discharge connector and comes with a T plug adapter and power cable. A 2A charger is included, along with an AC plug and power connector. DYMOZYNE claims a 1000-plus cycle lifespan, which is typical for lithium-ion packs at this price point. The case is sealed PVC, so it'll handle some dust and splashes, but don't expect it to survive a full submersion or heavy rain.
One thing worth mentioning up front: the form factor is rectangular PVC brick style, not a downtube shape or a Hailong or Shark style for mounting on a frame. You'll need to figure out where to put it on your bike, scooter, or whatever you're powering. Several Amazon reviewers mention using it under seats or in utility trays, which seems to be the intended use case. The battery ships with a 2A charger, an XT60 discharge cable, a T plug adapter, a power connector, and an AC plug. DYMOZYNE backs it with a 1-year warranty.
Real-World Battery Life and Range
At 432Wh, a 36V 12Ah pack gives you roughly 15 to 25 miles of range on a typical ebike setup, depending on your motor wattage, terrain, and how much you rely on throttle versus pedal assist. For a 350W motor, you're looking at a bit over an hour of continuous runtime at full power. For a smaller 250W motor, you can stretch that further.
But here's the catch that multiple buyers have pointed out. The BMS on this battery doesn't seem to deliver the advertised 30A continuous rating. One reviewer who bought this for a Razor MX650 conversion put an amp meter on it and found the BMS was tripping at around 8 amps. That's a massive discrepancy. If accurate, that means this battery is really only suitable for motors under 300W, not the 1000W motors the listing mentions. Another user reported that the battery just shut off on them entirely.
That said, a few buyers are running this in lower-power setups without issues. One reviewer uses it to power a 350W motor on a folding ebike and says it works fine for weekend trail riding. Another had good results fitting it into a Razor MX500 kids electric dirt bike. So it seems like the BMS works fine in lower-demand applications, but pushes back hard when you ask for sustained high current.
What Amazon Reviewers Are Saying
With a 2.5 out of 5 star average across 7 reviews, this is not a universally loved battery. But the feedback is actually pretty split between people who had a completely smooth experience and people who hit real problems.
The positives from buyers:
The main thing people like about this battery is that when it works, it works. One reviewer gave it 5 stars for fitting perfectly in a Razor MX500 and said it's been great so far since the install. Another buyer picked it up for a Jetson electric scooter and confirmed the fit works, though they cautioned that you need to measure your original battery before ordering to get the right size. A folding ebike owner reported that the battery fits neatly in a bag under the seat and provides enough power for weekend rides on a 350W motor setup. They also mentioned DYMOZYNE's customer service was responsive when they had sizing questions before buying.
The negatives from buyers:
The complaints center around a few recurring themes. The most serious one is the BMS issue we covered above. One detailed review found the BMS tripping at about 8 amps, making the 30A rating on the listing feel misleading. In addition, a couple of reviewers noticed that their pack stopped functioning after shipping. These reviewers described the quality as less desirable than previous packs they had purchased. Shipping delays and poor seller communication were also mentioned by at least two reviewers.
The takeaway from the reviews is pretty clear: this battery works well in low-power applications below about 300W, but you're gambling a bit on quality control and BMS performance. The 2.5 star average reflects that split right down the middle.
Who Should Buy This Battery
This battery makes the most sense for a very specific kind of buyer. If you have a small scooter, a kids electric ride-on toy, a folding ebike with a low-power hub motor, or any project that pulls under 10 amps continuous, the DYMOZYNE pack could work out fine for the price. The compact size and light weight are real advantages for tight spaces.
Good for:
- Small scooters
- Kids electric ride-on vehicles like a Razor MX500 or MX650
- Folding ebikes with low-powered hub motors in the 250W to 350W range
- DIY projects needing modest amounts of power
- Under-seat or bag-mounted battery replacements
- Budget builds where price is the top concern
Not great for:
- High-power hub motor builds drawing over 300W sustained
- Heavy riders on steep terrain needing continuous high current
- Anyone wanting a 1000W-capable battery as advertised
- Riders who can't afford downtime if the battery fails
Frequently Asked Questions
Will this battery work with my Razor MX650?
Possibly, but be careful. One reviewer used it for an MX650 conversion and reported that the BMS tripped at around 8 amps, which is way below the 30A rating. The MX650's motor draws more than that under load, so you could run into the same problem. An MX500 with its smaller motor is a safer bet based on buyer feedback.
What connectors does this battery use?
It comes with an XT60 discharge connector and includes a T plug adapter and power cable. Most ebikes and scooters will need an adapter to match whatever connector your controller uses, so check that before buying.
How long does the included charger take to charge?
The included 2A charger takes about 5 to 6 hours to charge the battery from empty. That's on the slower side, but for overnight charging it works fine. If you need faster charging, you'd need a separate higher-amp charger.
Is this battery waterproof?
No. The PVC case is sealed and offers some resistance to moisture, but it's not fully waterproof. Keep it away from heavy rain and don't submerge it. For wet conditions, you'll want a battery with an actual IP rating.
Can I use this battery on a 48V system?
No. The battery runs at 36V nominal. Using it on a 48V system will damage both your controller and the battery. Make sure your controller and motor are rated for 36V before buying.
What's the warranty?
DYMOZYNE offers a 1-year warranty. According to the listing, they'll replace the battery if you encounter any quality issues within that year. After the warranty period, they say their technical team may still offer support, but Amazon's return window is much shorter.
Bottom Line
For riders who need a cheap ebike battery and are willing to accept some risk, this DYMOZYNE pack represents a bargain. At under 25 cents per watt-hour for a pack with 432Wh of capacity, you'd be hard pressed to find anything on Amazon that compares. For small scooters, kids ride-ons, and low-power folding ebikes, it might be exactly what you need at a price that's hard to beat. But the reviews suggest the BMS doesn't deliver anywhere near its rated 30A, and a few buyers had units that failed or arrived late. Check the comparison table to see how it stacks up against competitors.
