Most 52V packs in this price range will include a 2A charger and a 25A BMS. The LGNUO 52V 20Ah pack comes with both, including a 3A charger.
The LGNUO 52V 20Ah pack has the benefit of having a 30A BMS. A 30A BMS at 52V will have the ability to handle approximately 1560W of peak power. With many 1000W ebike motors you may find there is enough room for additional acceleration or increased hill climbing. You can compare the LGNUO 52V 20Ah option to other options by looking at our ebike battery comparison chart.
Specifications and Build Quality
The LGNUO 52V 20Ah measures 9.8 x 5.6 x 2.79 inches (249 x 142 x 71 mm) and weighs 10 pounds. Compared to the 48V model from LGNUO, the 52V model is almost two pounds lighter. We think the difference in weight is due to different cell arrangements and casing designs.
The housing of the pack is made of a plastic shell that protects the contents from water and physical impacts. This makes it perfect for outdoor applications and DIY builds where frames may not be mounted perfectly. It is still compact enough to fit into a triangle bag or rack mount.
Included with the purchase are:
- The pack itself
- An XT60 extension cord
- A 58.8V 3A charger
- A user guide
We appreciate the inclusion of the 58.8V 3A charger. Many lower priced battery options usually include a 2A charger. Using a 3A charger reduces recharge time down to about 6-7 hours from dead to fully charged versus 8-10 hours with a standard 2A charger.
Protection and Design Features
The 30A BMS covers the four main types of protection:
- Over-charging
- Over-discharging
- Over-current
- Short-circuit
At 52V nominal, a 30A BMS can safely handle up to about 1560W continuously. While that might be a bit tight for a 1500W motor, it gives plenty of extra headroom for most standard ebike motors below 1000W.
The LGNUO 52V 20Ah uses what they call Grade A lithium-ion cells. They claim these cells have long-lasting cycles and consistent performance. Take these claims with reasonable caution.
Fast charging is a nice advantage here. The included 58.8V 3A charger charges the pack in about 6-7 hours from dead to fully charged, which is about 25 percent quicker than standard 2A chargers provided with most low-cost ebike battery bundles.
Range and Real World Results
Given that a 52V system can supply slightly more efficient operation than a similar setup running at 48V, the actual useful range is expected to be greater than a comparable 48V pack. Based on the capacity and voltage, we estimate 28-35 miles on a 750W motor depending on rider weight, terrain, and pedal assist usage. On a 1000W motor, expect about 20-25 miles. The higher voltage means the motor draws fewer amps for the same power, which reduces heat and improves overall efficiency.
The pack contains an XT60 connector capable of handling more than adequate current for typical ebike applications. You should not have any trouble connecting this pack to your controller or motor. The included extension cable gives you some flexibility in where you mount the battery relative to the controller.
Who Should Buy This Pack
There are several potential users for this pack.
If you are seeking the improved efficiency and speed characteristics of a 52V system without breaking the bank on branded products, this pack is worth considering. The LGNUO 52V 20Ah offers a strong value in terms of price per Wh. For riders who want the extra speed of 52V without spending Cardo or Sena money, this hits a good middle ground.
Another good candidate is someone building an ebike project with a small frame requiring a compact battery solution. Given the compact form factor at about 10 inches wide and 10 pounds, it easily fits in triangle bags or on rear racks. Builders who have limited space will appreciate the slim dimensions.
Lastly, if you want faster charging, this is an excellent choice. The included 3A charger allows you to recharge about 25-30 percent faster than standard low-priced ebike battery bundles. That adds up over a season of regular riding.
The biggest concern is the lack of customer reviews. Only one rating exists at the time of writing. That said, LGNUO lists several battery configurations on Amazon, which suggests reasonable seller experience.
FAQs
Does this battery fit my ebike frame?
As mentioned, yes it does. The length works for most triangle bags and it is narrow enough for rear rack mounts. Measure your frame space first to be sure. The flat rectangular shape sits well on most rack trays without sliding around.
Is the 30A BMS sufficient for a 1000W motor?
Yes. A typical 1000W motor produces about 18-20A at full throttle. The 30A BMS has about half again as much headroom as needed. For 1500W motors the margin is tighter, around 3-4 amps of headroom, which is usable but not generous.
What kind of charger comes with this product?
An included 58.8V 3A charger. It charges the pack from empty to full in about 6-7 hours, compared to 8-10 hours with a standard 2A charger. That 25 percent faster charging is a real convenience for daily riders who do not want to wait around.
Can I use this for my scooter or go-kart project?
Yes. This pack is suitable for outdoor construction equipment or DIY builds with applications from about 200W through 1400W. The hard shell case and XT60 connector make it a versatile power source for all kinds of electric projects. It works well for scooters, go-karts, and even small electric vehicles.
Is the case waterproof?
The hard shell design offers water and shock protection for outdoor use. It handles rain and splashes during riding. Do not submerge the pack. The housing holds up well in wet conditions based on the build quality we can see from the product photos. It is sealed well enough for regular riding in the rain.
How does 52V compare to 48V?
52V systems provide higher top speed and better efficiency at the same power level. Motors run cooler and controllers draw fewer amps for the same output. The difference is most noticeable on hills and during hard acceleration where the extra voltage keeps the motor in its efficient range.
If 52V performance and fast charging at a budget price fit your build, the LGNUO 52V 20Ah is worth a serious look. Compare it against other 52V packs on the ebike battery comparison table.
