1560 watt-hours in a single pack. That kind of capacity used to mean wiring two batteries together or running a massive triangle pack that weighed a ton. The LGNUO 52V 30Ah ebike battery fits in a 12.6 x 6.1 x 3.1 inch box and weighs 29 pounds. While 1560 Wh would have been unheard of in a single package even a few years ago, you can get that kind of juice today.
Whether it gets you through a full day of riding depends on your motor and how you ride.
Specifications and Build Quality
This is a nominal 52V pack with a 30Ah capacity. The resulting 1560 Wh of juice translates to a realistic expected range of approximately 30 miles on a 2000W setup operating continuously wide open throttle to 60-70 miles on a 500W bike utilizing a combination of pedal assist and throttle operation. The calculated numbers appear accurate based on a calculation of 52V times 30Ah equals 1560Wh.
The case dimensions are 320mm x 155mm x 78mm. This is a fairly common configuration for high-capacity packs and while it is a substantial battery, the rectangular shape will generally allow for mounting to most frames with a flat top tube. The outer casing is hard shell construction providing some level of protection from impacts.
LGNUO advertises the inclusion of Grade A lithium cells within their pack along with pure nickel strip welds. Pure nickel provides lower electrical resistance compared to nickel plated steel, therefore it produces less heat during prolonged periods of operation. Included with the pack is an XT60 extension cord and a 58.8V 3A charger.
At approximately 29 pounds, the weight of this pack is roughly equivalent to what you might expect for a pack containing this much energy. You will certainly notice the additional weight when placing the bike on a lift or carrying it up stairs, however considering the amount of juice contained within, it is not excessive.
BMS, Safety, and Design Features
The primary distinguishing feature of this pack is its internal 40A BMS. Most 52V packs at similar prices include a 25A or 30A BMS. With a continuous current rating of 40A, the ability to handle peak motors rated at up to 2000W without cutting off due to excessive draw will provide considerable advantages if you run a high powered hub motor or mid drive that requires significant current to accelerate.
The BMS also provides the standard protection functions including overcharge, over-discharge, overcurrent and short circuit protection. No fancy features are provided, however all of the basic functions appear well implemented. In addition to protecting the user and preventing catastrophic failure of the pack, the ability to sustain up to 2080 watts of continuous current output (with headroom to spare) allows for sufficient capability to support any commercially available electric bicycle motor rated at either 1500W or 2000W.
The external case design encloses the individual cells from potential exposure to liquid. According to information presented on the product listing page, there is currently no IP rating specified for this item, so users should mount this item such that potential splashing of water will not come into contact with the unit. If you plan to operate in wet conditions frequently, adding some silicone sealant material around the seams may help protect from moisture intrusion.
Real World Expected Range
Actual range varies greatly depending on both your motor and how you choose to operate it. These are approximate ranges based on the above specifications:
- On a moderate pedal assist setting on a 500W ebike: 60-70 miles.
- On an average throttle/pedal assist setting on a 1000W setup: 35-45 miles.
- On an extreme throttle setting at full power on a 2000W dirt bike style setup: 25-30 miles.
These estimates are somewhat subjective since they vary greatly depending on several factors. However, having a pack capable of delivering approximately 35-50% more energy than many competitor products offers great flexibility for those with varied riding styles.
As noted earlier, the primary benefit of this BMS is in high-draw applications. A high-powered motor like a 2000W hub draws approximately 38.5 amps at full throttle. Most stock BMS units typically do not exceed this rating. Therefore, with a BMS capable of sustaining this level of current draw (and possibly slightly beyond), riders can rest assured knowing they have adequate margin prior to hitting the cutoff.
Finally, charging this pack at a rate of just three amps takes approximately ten hours when starting from completely dead.
Who Should Purchase This Pack?
Based on the characteristics described in this review, buyers that could benefit from purchasing this pack include:
- Commuters that prefer to recharge every few days rather than daily.
- Buyers with high-power setups requiring more than the typical 25 or 30 amp BMS offered by competitors.
- Users tired of being concerned about range anxiety with their existing pack that contains significantly less energy.
The primary drawback associated with this product is the absence of customer feedback. At the time we wrote this article, there were zero customer reviews listed for this particular product on Amazon. Considering the price and manufacturer reputation, there is an inherent risk involved when purchasing untested items online.
That being said, LGNUO appears to be a legitimate seller on Amazon's marketplace. If you require multiple reviews for confidence regarding an item prior to purchase, please compare the specifications in this review article to others found in our comparison table featuring competing 40A BMS packs of similar capacities.

Frequently Asked Questions
Will this battery fit my ebike?
First measure your ebike's battery mounting location. The dimensions for this battery case are 12.6 x 6.1 x 3.1 inches. Rectangular downtubes should accommodate most ebikes, however larger frames with limited clearance may present problems.
What type of connector is included?
An XT60 connector is standard. An XT60 extension cord is included as part of the shipping materials for easy routing around your controller.
Is there an included charger?
Yes, an included charger supports charging at 58.8V at 3 amps.
Can I install this battery on a 48V ebike?
No. The battery charges to 58.8V when full. Installing this pack on a 48V controller will damage the controller. Please verify compatibility prior to purchase.
How long does the battery last per charge?
Around 30-60 miles depending on motor power, throttle use, rider weight, and terrain. At 1560Wh it is one of the higher-capacity options available. See the current price on Amazon.
