The Shuntongda 52V 17.5Ah is available only for the Lankeleisi X3000. For that bike it has serious capacity (910 wh) in a 52 v architecture inside the DCH-009 case. However, the drawback is the same one as all other special packs: almost nothing but one five star customer review, and a Fitment list you simply can't avoid.
Specs and Value
First, the math: 52V times 17.5Ah = 910 watt-hours. While that is significantly better than average capacity in a mid-range commuter pack, the additional volts (higher than normal 48 volt ebike) also gives you more room for speed, possibly even increasing the top end of your ebike. Keep in mind that the increased volts mean that each component in your system (charger and controller) must have an input voltage of 52 volts. Using a 52 volt pack with a 48 volt controller may damage it. And don't forget the added weight in tighter corners will affect handling.
A pack configured for 52V uses 14 cells in series vs. 13 cells in series for a 48volt pack. More cells in series produces a higher voltage limit for the motor so the motor can produce the same amount of power using less current. Less current reduces heat loss in wiring and controller. On the other hand, everything downstream of the motor must be able to accept higher voltage.
The 30A BMS handles the standard protection set: overcharge, deep discharge, overcurrent, and short circuits. Charging uses the pack's designated 54.6V charger, and a full charge from empty runs several hours given the capacity. Charge indoors at room temperature when possible, since cold charging is hard on lithium cells.
As mentioned earlier, capacity is measured at 17.5Ah and exceeds the typical range of 10Ah to 13Ah commuter packs. You are trading endurance over agility and thus, the pack will grow in weight.
Fitment for the Lankeleisi X3000
This pack was designed specifically for the Lankeleisi X3000. This pack was built for the Lankeleisi X3000, and the DCH-009 cradle is not shared widely across other brands. It is not a universal pack. Compare your current battery against the listing photos and confirm the connector matches before ordering, down to pin count and housing shape. A powered-up mismatch can short the pack or the controller. If either detail differs, the pack will not seat in your mounting bracket. Older X3000 revisions can differ in bracket type, size, or hole locations, and mounting discrepancies are among the most common complaints on third-party replacement packs. Any mismatch turns this into a heavy paperweight, so verify every dimension first.
Although we discussed mounting hardware dimension compatibility issues earlier, connector interface compatibility is equally important. Connectors need to match exactly: pin count, pin thickness & housing shape. Incorrectly mated connector powered up can short out the pack or the controller. Shuntongda provides no wiring diagrams so you'll have to make the comparison yourself. Any difference means stop now and look for adapter or another pack.
Real-World Range and Power
In practice, 910Wh equals consistent power delivery right until the end of a ride, with less voltage sag on climbs than smaller packs.e. Speed at which you consume wh depends upon throttle habits and terrain type. When you drive continuously hard enough to deplete Battery, voltage drops faster as ride progresses and top speed increases with decreasing voltage towards the end of charge cycle.
Picture two riders climbing the same hill on identical bikes, one with a 13Ah pack & other rider has this one. Smaller pack sags under load (grade) where larger pack maintains constant voltage level & keeps pulling downhill. That consistency under load is true advantage of extra capacity. Price for that advantage is added mass that shifts center of gravity and reduces cornering ability. Tourists usually don't mind this trade off.
What Amazon Reviewers Are Saying
There is a single five-star rating in the review section. That is the entire evidence base, and it tells you nothing about cycle life, heat tolerance, or winter performance. base. No one outside Shuntongda can tell you how these cells perform under heat cycling & cold cycles or after year of weekly charging.
Cells lose capacity due to heat and cold cycles regardless of brand, which is exactly why independent reviews matter so much for a niche pack like this one. Without independent reviews, it is impossible to know whether Shuntongda chose quality cells or cheap ones. Purchase now & you become unpaid beta tester. Whether pack last years or fades within months is unknown until it happen to you.
Who Should Buy This
Buy this only if you own a Lankeleisi X3000, require the 52V configuration, and accept first-mover risk on a listing with one review. Buyers who prefer proof should wait for the review count to build before committing to a pack this expensive. Everyone else should keep shopping.

Frequently Asked Questions
Will It Fit My Lankeleisi X3000 Plus?
Yes, the Lankeleisi X3000 Plus is listed as one of models supported by Shuntongda, and therefore should match dimensions based upon housing style of DCH-009. Double check your original ebike battery to specifications of 16.5 x 4.5 x 2.3 inches prior to making purchase for your own assurance.
How Much Usable Energy Does This battery Contain?
This battery offers 17.5Ah @ 52 volts of usable energy which translates to about 910 wh of usable energy. Greater usable energy due to higher voltage compared to standard use voltage of most fat tire folding ebikes typically rated at 48 volts increases range between charges.
Are There Locks on This battery?
Yes, a safe lock switch is built into this battery for improved protection against theft. Also included is a power supply control switch for complete disconnect from ebike when it is parked or stationary.
What Kind of BMS Does This battery Utilize?
BMS used on this ebike battery is rated at 30 amp with indicated maximum rated discharge being 30 amp. That should be plenty sufficient for usual loads encountered on most folding fat tire ebikes' motors and prevent excessive heat buildup in wiring and controller due to rapid acceleration from standstill utilizing throttle.
