A dead pack on a folding ebike leaves you with a narrower problem than most battery shoppers face. The XP Lite's battery slot is short, and most replacement downtube packs are built long. Buy the wrong one and no adapter fixes it.

ShunTongDa sells this 10.4Ah pack in the 410mm length the XP Lite 1.0 actually takes, and it costs well under what a first-party pack runs. That gap is the whole reason it sells. The ShunTongDa 48V 10.4Ah Lectric XP Lite replacement battery is a 499.2Wh pack on a 30A BMS, sold at 188.00 with the 54.6V 2A charger in the box.

It carried 4.0 stars from 15 ratings when we checked, with a histogram that skips four and three stars entirely, and the spec table promises a 1-year warranty. That record is the honest center of this review, because the rating has moved down from the small perfect score the pack first shipped with.

ShunTongDa 48V 10.4Ah Lectric XP Lite replacement battery, the 410mm folding pack

The 410mm question decides everything

This pack measures 410 x 100 x 42mm, and that first number either fits your frame or it doesn't.

Most downtube replacement packs run 430mm, which is the length the bigger XP frames take. The listing says outright that this one does NOT fit the XP 1.0, 2.0, 3.0 or Step-Thru models. The battery bay on a folding XP Lite has no room to spare, so 20mm isn't a spec quirk, it's the difference between a battery and a return label.

Two buyers in the record found that out the expensive way. One rode a Sasikeibike folding bike, one never named the bike at all, and both texts end the same way, with the pack going back.

The listing fights this harder than most sellers bother to. It asks you to measure your original battery before ordering, it prints the not-fit list in capital letters, and it offers a photo check of your bike and old pack within 24 hours.

Use that photo check if your frame isn't a stock XP Lite. The Janobike H20 and SMLRO S9 names are the only other bikes the listing actually commits to. The claim that burned both buyers is the softer line further down, the one about various adult electric bicycles sharing the 410mm housing.

Shared length is necessary but not enough, because the cradle shape, connector and key position all have to match too, and a 410mm tube in the wrong cradle is still a return.

Five XP Lite owners in the record report the opposite outcome, a drop-in fit with no changes. One of them bought a second pack and noted it matches the original down to the patent number molded on the side.

What the numbers on the page add up to

The spec sheet is short, so it's worth doing the sums the listing leaves undone. 48 volts times 10.4 amp-hours is 499.2Wh, and the 30A BMS on that voltage works out to roughly 1,440W of continuous draw on a fresh pack. That covers even the 1200W ceiling the heading claims, though the bullet body underneath only names 350W, 500W and 750W motors.

Nothing in the record stresses the BMS either way, because the XP Lite's motor sits far below all of those numbers.

The 20 to 35 mile range claim is the listing's own figure, and it holds up against the bands in the ebikes.ca battery guide. A power-hungry rider burns 14 to 20 watt-hours per kilometer there, and a typical assist rider 9 to 12.

Run 499.2Wh through those bands and you get roughly 25 to 36km flogging it with no pedaling, 42 to 55km at a steady assist pace, and past 80km if you're barely touching the motor. No owner has published a number against any of that, so treat the listing's band as arithmetic rather than proof.

One figure deserves suspicion rather than trust. The spec table lists the battery weight at 3kg. Divide 499.2Wh by 3kg and the arithmetic says about 166 watt-hours per kilogram. The ebikes.ca guide puts a complete lithium-ion ebike pack, cells, case and BMS together, at around 110.

A light build can land above the norm, but this is also the kind of number that shows up when a capacity spec is generous, so the honest move is to meter the pack early rather than argue about it. A second weight line says 6.82 pounds, which agrees with the 3kg figure, so any gap sits in the capacity figure, not the weight.

The listing also carries small evidence of a page assembled in a hurry. The Model Number field holds the text 16.14 inches, which is a length, not a model number.

The Model Name reads JD-006FZ104 while the fit copy talks about the DCH-006 format. The cell composition says lithium-ion without naming a brand anywhere. None of that is disqualifying on its own, but it's the same page-care gap you see on listings that change hands or get rebuilt often.

What 15 ratings actually say

The record shape is unusual, and it's worth reading closely before you trust the average. Fifteen ratings produce 4.0 stars, with 74 percent five-star and 26 percent split between two-star and one-star.

Nothing sits at four or three stars at all. All 11 written reviews carry purchase confirmation, which is rarer than it should be on Amazon, so nobody is arguing about fake praise here. The split is real.

The only text on the page with a helpful vote is the March 2026 one-star, three sentences saying the pack will not fit and is going back.

On a page where fit is the dominant risk, the community's most-endorsed signal is the failure case. That's actually useful, because it tells you the average is hiding two different outcomes rather than a mediocre product. Nine owners report warm experiences, mostly short texts about perfect fit and fair cost, and both negatives are fit failures rather than electrical ones.

The details buyers confirm are narrow. One owner upgraded from the XP Lite's stock 7.8Ah pack in October 2026 and calls the capacity jump significant. Another says it looks identical to the original pack it replaced.

A third notes it costs much less than the one Lectric sells, then closes with the honest part, hopefully it will last.

Nobody has published a range figure, a charge time, or a report past nine months, because the oldest text on the page is from January 2026. You're buying a pack whose longest data point is younger than a school year, and no review, this one included, can fix that.

Charging, warranty and the cycle-life claim

The charger is included rather than an extra purchase, a 54.6V 2A unit with an LED indicator, and the 5 to 6 hour charge claim checks out. Two amps at pack voltage is roughly 96 watts of input, and 499.2Wh divided by 96 lands a touch over five hours, so the listing's band is real rather than hopeful. Overnight charging covers a daily commuter's needs with hours to spare.

The cycle-life bullet is where the listing reaches. It claims 800 to 1,000 full cycles while keeping more than 80 percent of original capacity, which runs two to three times the 300 to 500 cycles Battery University gives as the maker norm for consumer lithium-ion, and the listing names no chemistry that could explain the difference.

No buyer can check a cycle claim in under three years of daily riding. The practical reading is simple: the claim is a promise, the 1-year warranty is the enforceable part, and the gap between them is yours to manage. Meter the pack's capacity inside the warranty window, because a pack that meters at 80 percent in month ten is telling you which end of the cycle claim you got.

Water resistance is rated IPX5, which means protection against spray from any direction, not immersion and not a pressure jet. That's consistent with a battery living in an open folding frame, and it argues against leaving the bike under a hose or riding flooded trails. The mechanical key doubles as the power switch, so the pack stays off in transit and you don't nurse phantom drain between rides.

What it costs against the field, and who should buy it

At 188.00 for 499.2Wh, this pack sits among the most expensive of the 301 batteries we track per watt-hour, and the live position renders in the specs box on our ebike battery comparison table, so you can see the cheaper bands directly around it. That's a plain fact worth sitting with, because the same money in a standard 430mm-format pack buys meaningfully more watt-hours, and several of those packs also carry longer track records.

What the money buys here isn't value per watt-hour, it's the 410mm case itself, which almost nothing else on the market targets.

So the decision reduces to the question the title asks. If your old pack measures 410mm, this is one of the only purpose-built replacements available, the fit record among XP Lite owners is clean, the charger's included, and the 1-year warranty gives you a metering window.

If your pack is 430mm, don't bend the fit rules to make this work, because the 430mm ShunTongDa 48V 10Ah tube pack serves those frames with a longer record behind it. If you ride a Janobike or SMLRO rather than an XP Lite, treat the works-on-many-bikes line as unproven until you've used the listing's photo check, because two buyers trusted the fine print and shipped a battery back.

Frequently Asked Questions

Will it fit my bike?

Measure your old battery first. The pack fits 410mm bays, which covers the Lectric XP Lite 1.0 plus the Janobike H20 and SMLRO S9 the listing names, and it does not fit XP 1.0, 2.0, 3.0 or Step-Thru frames, which need 430mm packs. If your bike isn't one of those, send the listing's support team a photo of the bike and old pack, and they commit to a fit answer within 24 hours.

What range should I actually expect?

No owner has published a number, so the honest answer is arithmetic. The ebikes.ca guide puts typical assist riding at 9 to 12 watt-hours per kilometer, which turns 499.2Wh into roughly 40 to 55km.

Throttle-heavy riding cuts that toward 25km, and gentle pedaling stretches it past 80km. The listing's own 20 to 35 mile band sits inside those figures.

How long does it take to charge?

About 5 to 6 hours on the included 54.6V 2A charger, and the arithmetic agrees with the claim. Two amps at 48 volts is about 96 watts, and a 499.2Wh fill needs just over five hours of that. A full overnight charge covers a daily commute without thinking about it.

Is a third-party pack safe to run in place of the Lectric original?

The protections on paper are complete: a 30A BMS covering overcharge, over-discharge, over-current and shorts, plus IPX5 splash resistance and a key-locked power switch. What no listing can give you is field history, and this pack's oldest purchase-confirmed report is nine months old. The sensible approach is to meter capacity and watch the first few charge cycles closely rather than trust any brand's word for safety.

What if it doesn't fit?

Return it, and buy through a path that makes that cheap. Both negative texts in the record are fit failures, one a Sasikeibike that the works-on-many-bikes claim didn't survive and one an unnamed bike. The listing pairs its fit warnings with a 30-day return policy for exactly this reason.
