Many of today's 48V eBikes seem like afterthoughts until you find yourself climbing a very steep hill. That's where the LZIXYM 20Ah pack attempts to address that issue by adding a tremendous amount of energy inside of a standard-sized housing. The LZIXYM 20Ah pack is essentially a simple solution to commuters who do not wish to worry about running out of energy while making the trip to work. If you don't want to think about.
If you want a pack that removes range math from every ride, this one covers it. The LZIXYM listing on Amazon
Technical Details and Performance
The LZIXYM 48V 20Ah pack is built for high usage. With a total capacity of 960Wh, it falls at the upper end of the average commuting battery. The brains behind the operation is a 30 Amp BMS. This will allow the battery to supply motors up to 1200 Watts, without limiting output due to excessive demand while climbing hills or heavy throttle application. High amp BMS units are typically the limiting factor for performance. they ensure that the cells can supply the needed amps when the motor calls for them on an incline.
Weight and Fitment
Installation size matters as well. Weighing in at 4.77kg, or approximately 10.5lbs, this is a fair trade off for its energy density. The battery measures 13.90 inches x 5.31 inches x 3.54 inches. As previously stated, this battery was designed to fit most frames, however, installing this battery onto a frame requires care.
One positive aspect of the design was putting the three pin discharge connector on top of the housing instead of the bottom. Many other manufacturers place connectors such as these at the bottom of their housings. Placement at the bottom makes connecting wiring for the bike more complicated when installed near the ground. The ease of accessing and connecting the wiring at the top is greatly appreciated.
As part of this kit, you receive the battery itself, the holder for attaching it to the frame, a charger, two keys, and instructions.
Folding Vs Seat Tube Mount
Reviewers should note a large contradiction within the product description. The title clearly states that this is a folding eBike battery. However, the technical specifications outline a seat-tube type of mounting system. This contradiction may result in buyers selecting the wrong item based upon their particular bike.
Verify your bike frame prior to purchasing this product. If you have a folding bike with a specific rear-type mounting system, this battery may not be compatible. If you have a standard mountain or commuter bike with a down-tube, the description for the seat-tube mounting would probably apply to you. The "folding" designation in the title possibly refers to its intended use on a folding bike. however, physically, this appears not to be so.
Take precise measurements of your frame for mounting space. The 13.9 inch length of this battery requires ample room between the seat tube and any components that may interfere with it. Don't just assume it will fit anywhere. Be sure to compare the mounting mechanism to your bike first.
Range Calculations and Real World Performance
At 960Wh, this battery represents nearly double the capacity of many standard commuter batteries at 500Wh. In practical terms, this gives riders new flexibility in planning rides.
Standard 500Wh batteries will give riders sufficient range for one day of riding with some reserve energy remaining. This 960Wh battery allows riders to accomplish either two days worth of riding or one extended weekend ride without stopping to charge.
The 30A BMS provides reliable delivery of energy from the battery when operating in high demand conditions. When you require 1kW of power from your motor, the battery must have sufficient headroom to maintain steady voltage. This unit prevents voltage sags commonly experienced with smaller capacity batteries under heavy load.
What Buyers Say About It
There isn't enough information available regarding buyer feedback specific to this product. There is only one reviewer listed at present. He gave it a five star rating. Although that doesn't tell us anything about performance or longevity of this product, it tells us that he received his order and it worked as advertised.
We can't discuss long term cycling characteristics or potential weak spots based solely on one reviewers input.
Who Will Benefit From Purchasing This Product?
Buyers interested in this product will benefit from a few categories. They include: Commuter users who do not want to recharge their bikes mid-trip. Users of high wattage motors (500w - 1200w) equipped with 30A BMS systems. Mountainous terrain cyclists requiring additional range.
Those seeking ultra-light solutions should consider alternative products. At ten pounds and six ounces, this is a relatively heavy addition to any bike frame. However, if you're converting an old frame for longer distances, or creating a new conversion kit for long range travel, then this is a viable option based on energy to weight ratio.
One sizing note before ordering. The 960Wh rating assumes a healthy 48V controller, so riders running older 36V systems gain nothing from this pack, and the 13.9 inch length rules out frames with short seat tubes. Measure the compartment and check the discharge plug against your controller before committing.

Frequently Asked Questions
Is this battery compatible with my 52V motor?
This battery is designed to operate exclusively at 48Vs. Operating a 48V battery on a 52 volt controller will severely limit performance and/or create errors.
How long does it take to fully charge?
Charging times depend upon the charger used. On average, using a 2A charger will take four to five hours to fully charge a 960Wh pack.
Does it include the mounting bracket?
The packaging includes a holder for securing the battery to your bike frame. Please ensure the bracket design matches your bike frame geometry.
What is the purpose of the three-pin discharge port?
The three-pin connector is where the battery connects into your motor controller. The placement on top simplifies wiring connections compared to bottom-placed ports.
Can I install this battery in extremely cold weather?
Cold temperatures reduce lithium ion efficiency. Although this packs high capacity aids energy recovery slightly in extreme cold. expect reduced range due to temperature drops below zero degrees Farenheit.
Will replacing a failed BMS void warranty?
Typically yes. Failure of the integrated BMS necessitates replacing or repairing the whole unit.
What is the cell chemistry?
Most lithium ion packs (this included) utilize lithium-ion cells. They offer an excellent combination of energy density and weight.
Can I use another charger?
For optimal results, please use a charger that meets both voltage and amperage requirements for this pack.
