There is a point for ebike batteries (and a point in time) when you have spent as much money on the "brand" name as you spend on watt-hours and the DYMOZYNE 48V 20Ah battery fits into that area. The cost of this battery is less than 18 cents per watt hour and provides 960Wh of capacity in a lightweight 10 pound package sufficient for most 48V applications.
It may not be the most attractive battery nor will it show off Samsung or LG cells, but it doesn't have to. All it has to do is provide Range per dollar and it does. Check the current price of the DYMOZYNE 48V 20Ah on Amazon.
This product is intended for DIY builders and riders moving away from lead acid who want lithium at a low cost. Check out the comparison table to see how it stacks up against other 48V options.
Specifications, Built-In BMS and Build Quality
The DYMOZYNE 48V 20Ah is approximately 10.1 x 5.83 x 2.75 inches in size and weighs approximately 10 lbs making it a relatively light weight battery for 960Wh. Its size makes it easy to mount on almost any ebike frame.
The DYMOZYNE 48V 20Ah battery is encased in a PVC outer casing with a hermetically sealed interior casing that DYMOZYNE refers to as "military grade protection". In theory, the multi-layer design protects against corrosion and impacts better than a single layer design. The company estimates this battery will last through over 1000 charge cycles which equates to years of normal riding before you notice significant capacity loss.
Included within the DYMOZYNE 48V 20Ah battery is a 30 amp built-in BMS designed to protect against:
- over-charging
- over-dis-charge
- excess current
- shorts
- high temperatures
With its ability to support motors ranging from 150 watts to 1500 watts, the DYMOZYNE's BMS has plenty of room for most mid-drive and hub motor applications without having to throttle back during charge/discharge. When charging/discharging, the BMS automatically balances each individual cell so none of them works harder than another cell, which is part of why DYMOZYNE estimates that it can go through over 1000 charge cycles.
DYMOZYNE states that they utilize well-known lithium-ion cells and professionally match those cells. However, DYMOZYNE does not mention the name of the lithium-ion cell manufacturers. Since this is such a low cost product, that is quite common.
The addition of the PVC shell offers additional physical protection for wet or dusty conditions while allowing the rider to build a small commuter or heavy duty off road application using a motor range of 150W to 1500W. Check the current price of the DYMOZYNE 48V 20Ah on Amazon.
Customer Reviews on Amazon
Since this is a new listing on Amazon, there is only one customer review posted. The customer gave the DYMOZYNE 48V 20Ah 5 stars. They stated that they used the battery on a motor rated at 1500 watts and noticed a significant increase in runtime compared to their previous 10 ah lead acid battery.
The reviewer did note that the supplied charger was only a 2 amp charger and took approximately 8-10 hours to fully charge the battery after a prolonged ride. Even so, they were satisfied with the Performance and indicated they would purchase again.
That first five star is a positive indicator since the cost of this battery is less than eighteen cents per watt hour. However, with only one review posted, it is premature to make conclusions regarding long term reliability. As mentioned above, the initial feedback has been favorable.
Real-World Runtime and Range
At 960 wh, this battery should provide considerable Range for most builds. On average, a typical 48 v hub motor pulling 500 w continuously should allow you to ride for about two hours or approximately thirty-five to fifty miles depending upon your terrain, cargo load and throttle usage.
Increasing power consumption increases runtime but still allows for a full day of riding. If you're using a motor with a power output greater than 1000 watts, then you'll drain it quickly but the 30 amp BMS will allow you to use the entire twenty amps without triggering the protective circuitry.
Additionally, this battery will function with many 48 v scooters, tricycles and golf carts. Again, Range will vary based on application. However, 960 wh is a lot of juice for most uses. If you're planning on building an aggressive off-road bike, this will give you a great capacity-to-weight ratio at approximately ten pounds. See our comparison table for how it compares to other forty-eight volt twenty amp options.
Who Should Buy This Battery?
If you want the cheapest option for a 48V 20Ah pack available today and do not require a specific branded battery, this is worth a close look.
Great For:
- DIY builders looking to maximize value from their 48V 20Ah pack.
- Riders upgrading from lead acid wanting lithium at a reasonable price point.
- Any rider using motors rated between 150W and 1500W with a single battery.
- Commuters needing thirty-five miles of range.
Not Great For:
- Riders that want cell brand names like Samsung or LG.
- Anyone expecting a fast charger included in the box.
- Those interested in seeing multiple reviews prior to purchase.
- Users requiring a specific form factor such as downtube or shark mounts.
This product offers a great option for maximum Range per dollar for most forty-eight volt builds.
Frequently Asked Questions
What voltage does this battery operate at?
Forty-eight volts nominal. It will work with any motor or controller designed for 48V systems.
What is the actual capacity?
960 watt-hours, or 48V multiplied by 20Ah.
Will this battery function with my motor?
Any motor from 150W to 1500W running off 48V, including hub motors, mid-drives, and scooter motors.
How long does charging take?
About ten hours at 2A. A higher-amperage charger cuts that significantly, and is worth buying if you ride daily.
Is it waterproof?
The PVC shell over the hermetically sealed inner case protects against splashes and moisture. It has not been rated for submersion.
What type of connectors are used?
Standard XT60 and T-plug connectors used in most controllers and DIY builds. Adapters are easy to find for Anderson plugs.
Conclusion
The DYMOZYNE 48V 20Ah offers excellent bang-for-your-buck for anyone looking to build or upgrade an ebike on a budget. At under 18 cents per watt-hour, it is one of the least expensive 48V 20Ah packs available today. While long-term review data remains sparse, the early feedback indicates a promising future. If you are looking for an affordable ebike battery that works across multiple builds and want maximum value for your battery dollars, the DYMOZYNE is worth considering. See current pricing on Amazon.
