The LOLRKO 48V 14Ah battery contains 672 wh within a six-pound soft-pack. A 20A BMS and PVC wrapping raise questions about how it holds up over time. See the current listing on Amazon. The review base is thin, so the specs do the talking.
The LOLRKO enters the crowded budget segment of the market with a very simple idea: you get a lithium cell wrapped in PVC, a 54.6 v 2 amp charger, and a t-plug to xt60 adapter for those controllers that use the commonly used connector. The LOLRKO supports motors ranging in rating from 250 w to 750 w, thus making it suitable for applications such as e-bikes, electric scooters, trikes and conversion projects that have a 48 v input. The seller warns against submerging the battery and advises users to put it in a battery bag when installing it in an open position on their bike or vehicle.
At its price, the LOLRKO offers customers a budget friendly way to achieve some good mileage. The 20 amp bms has several features including overcharge, over-discharge, current limits, voltage protection and short-circuit protection. Customers receive 1,000 plus charge cycles out of their purchase. With the 672 wh capacity, customers may be able to achieve significant mileage on most setups that run at 500 w to 750 w.
Specifications and build quality
All the Specs appear to be valid. Forty-eight multiplied by fourteen equals exactly 672 wh. That is what most customers watch for. The soft-pack design utilizes PVC wrapping instead of a metal case. This keeps the weight lower than a metal case, however, requires greater care in how it is mounted. Contacting hard items (such as frames) and/or road debris could cause damage to the PVC. The adapter included for t-plugs to xt60 eliminates confusion regarding compatibility. Many 750 w controllers utilize xt60. smaller motors normally utilize t-plugs. Now customers do not have to purchase separate wiring since they now have both connectors.
Customers can determine whether or not this battery fits their mount style based upon measurements listed in our comparison table. They also need to ensure that there is adequate clearance between the battery and surrounding parts of the frame.
Bms and Safety Features
Protecting each individual cell is the primary function of the bms. Overcharging protects cells from receiving excessive voltage during charging. Under-charging protects cells from draining to levels where capacity loss occurs due to prolonged exposure to low voltage. Overcurrent protection limits current flow to prevent damage caused by drawing excess currents. Protecting cells from being damaged due to excessive voltage, either too low or too high, is accomplished by voltage protection. Protection against overload and shorts disconnects the power supply if problems occur.
It means this battery can feed a 500 w to 750 w motor without difficulty because the bms has headroom at 20 a. To provide an example, a 750 w motor operating at maximum output produces approximately 15 a from a 48V pack. The bms provides ample room.
If you attempt to exceed 1000 w (which is much beyond most e-bike ratings), you may see the bms trip during extreme acceleration. While protecting the cells, this limits performance.
The provided 54.6 v 2a charger is basic but serves its purpose. When charged fully from empty, it will take approximately seven hours. Check the LOLRKO price on Amazon before you decide. Since charging lithium cells slowly reduces potential degradation compared to rapid fast charging, this is recommended.
In addition to providing specifications for the product, the seller cautions against submersion and recommends using a battery bag if the mount is open to weather and/or road spray.
Range and real world performance
The calculation begins simply. Divide the total wh capacity by estimated wh/mile for your typical ride scenario. As an example, assume you have a mix of flat and hill terrain and your 500 w to 750 w setup consumes 15 to 20 wh/mile. That places your estimated Range at approximately 33 to 45 miles per charge for casual pedal-assisted riding with moderate throttle application. On extremely hilly routes or full throttle commutes, actual wh/mile increases to approximately 20 wh/mile. Thus, real-world Range falls nearer to the lower end of the calculated band.
More important than any other variable when estimating Range is motor sizing. Smaller motors consume less energy and therefore increase the Range of the battery. Larger motors burn through capacity at an accelerated rate. Other variables include wind resistance (air resistance), rider weight, and tire pressure all contribute to increased energy consumption and decreased Range.
As mentioned previously, soft-packs present a practical limitation in terms of mounting methods. Without a rigid metal shell surrounding the battery, proper mounting is required. Additionally, cleaning and protecting the PVC wrapping from road debris and weather-related elements must be performed properly. Using a protective bag around the battery can protect it from damage resulting from these factors.
Based on customer comments on Amazon, it appears that the LOLRKO delivers on its Specs. There are currently Four positive reviews indicating that customers received value for their money. Based on its Specs alone, the LOLRKO seems to offer a budget-friendly alternative for customers seeking additional Range without paying too much. Soft-packing offers reduced weight for transportation purposes or maintenance situations. however, it requires careful attention to protect the PVC wrapping from damage related to debris impacts and abrasions.
For occasional commuters who wish to ride lighter or campus riders looking for extended ride ranges without breaking the bank. or weekend trail enthusiasts who desire sufficient Range for leisurely rides. the LOLRKO meets all of their requirements without introducing unnecessary complexity.

Who is this battery for?
Use this battery if you are in need of a budget alternative battery with 672 wh capacity for a 48V system. The adapter provided for converting t-plugs to xt60 adapters allows connection with multiple types of controllers. The 20A bms protects against excessive current flow and handles continuous operation of motors ranging in power from 500 w to 750 w without excessive strain. Each lithium cell receives 1,000 plus charge cycles, allowing for years of continued operation prior to replacement. Due to its light weight soft-pack construction, this battery is lightweight enough for transportation to service areas or maintenance locations.
Do not use this battery if:
- your motor draws continuous loads exceeding 750 watts.
- your motor will continually operate above its continuous load rating (i.e., you'll always be "on" rather than just assisting).
- you prefer rapid charging (the provided charger operates at two amps).
- you need a rugged metal enclosure for off-road usage (soft-packs are more fragile).
Although there are Four reviewers who gave this battery five star ratings on Amazon. there are still relatively few reviewers in total. The five-star average reflects real experiences. however, the reviewer sample is small. Although this battery looks promising according to its Specs. actual durability over time in regular daily usage remains difficult to validate. If you prefer larger samples of reviewers' experience. consider checking other battery reviews for products with larger user bases. However. if you believe in Specs and want a budget alternative. give the LOLRKO consideration. Check prices on Amazon
Frequently Asked Questions
What motors will support the LOLRKO 48V 14ah batteries?
This battery supports motors rated at 250 w, 350 w, 500 w and 750 w. The bms is capable of supporting motors up-to 750 w when operating at maximum output. Although higher-rated motors are supported. the bms will restrict power delivery prior to reaching peak output of the motor. Review your controller voltage rating prior to purchase.
How long does it take to charge?
Charging takes approximately seven hours when utilizing the included charger set at two amps from zero volts completely discharged. Charging partially (from fifty percent discharge) takes approximately three-and-a-half hours. Utilizing slower charging rates reduces potential degradation of lithium cells over time compared to using faster charging systems.
Will i be able to connect an xt60 controller?
Yes. Included with the purchase is a t-plug/xt60 adapter permitting you connect your controller using either t-plug or xt60 connector depending upon which type you have installed on your motor(s). Many controllers used for motors up-to 750W use xt60 connectors. while smaller motors (up-to250w & 350W) normally use t-plugs. Providing both connectors permits you avoid having to install additional wiring.
Are the soft-pack batteries safe for exposed mounting?
Yes. Soft-packs may be mounted in exposed locations. however, they require additional protection. While PVC wraps provide modest water/weather resistance. direct road spray. abrasion/debris impact and hard contacts with surrounding items (frames) may damage them over-time. Sellers recommend using a protective bag around the battery when mounting in an open location on your bicycle or vehicle. Protective bags add layers of protection against potential moisture damage and physical damage associated with debris impact or abrasion.
How many charge cycles do batteries support?
Manufacturers state their cells will last over one thousand charge cycles. That equates to over thirty thousand miles of riding prior to requiring replacement (assuming thirty miles per charge). Actual number of charge cycles dependant upon charging frequency and storage environment.
What type of warranty coverage is provided?
Battery comes with one year warranty covering manufacturers defects. failure of individual lithium cells and normal usage. Damage resulting from water immersion/submersion or improper installation of battery falls outside warranty coverage parameters. Retain your receipt and contact seller through Amazon for initiating claims process for warranty coverage.
