A cracked Aventon Pace pack leaves you with an odd problem. The bike is fine, the motor is fine, and the part you need lives inside a plastic case most owners never think about until it dies. Official replacements cost brand-name money, and third-party sellers move in and out of the marketplace faster than the bikes themselves.
SDTYYP's 48V 14Ah pack was one of those third-party options. It copied the Reention Dorado Plus case that Aventon and NCM used, matched the factory 672Wh capacity, and priced itself under the official part. Earlier this year its Amazon listing disappeared, and any review now works from the recorded specifications and stored images rather than a live page.
That changes what a review can honestly do. There is no owner record to quote, because our data never captured a rating or a single review. What the record does hold is a spec sheet that checks out against itself, a shared frame format that outlived the seller, and a price worth weighing against the current market.
The SDTYYP 48V 14Ah ebike battery recorded 672 watt-hours for 309, in an integrated downtube case sized for the Aventon Pace 350, the Pace 500 and the NCM Moscow. Unlike most budget listings, its own numbers agree with each other: the recorded 25A BMS allows about 1200W continuous at 48V, so the title's 1000W motor ceiling sits under it with room to spare.
The price per watt-hour is the weak spot. It sat among the most expensive packs on our ebike battery comparison table, and the listing skipped nearly every detail a replacement buyer needs. The page has since died, and what is left is a useful guide to buying a shared-format pack from whoever sells them next.
A dead listing for a format still on the road
Both ways of checking this ASIN now fail. The listing page returned Page Not Found when probed on 2026-11-02, and Amazon's catalog API rejects the identifier as invalid. That two-way death signature matches what other budget sellers left behind this year, and it means the exact pack in the stored images may never be listed again.
Affiliate links in this article point at a live Amazon search for equivalent 48V 14Ah Dorado-format packs rather than a dead page.
Our data row never recorded a rating or a review count for this ASIN, and no review text was ever captured. The old version of this article claimed owners have reported good fitment and range, but it named no counts, no quotes and no specifics, so none of that survives into this rebuild. There is no owner record to draw on, and the article does not pretend otherwise.
The format is the reason this death matters to anyone. Reention's Dorado Plus case is a shared downtube design, not a part unique to one brand. Replacement sellers in the same class list it against the NCM Moscow, Aspen, Milano and Venice, the Addmotor M-5600, Surface604 bikes, the VoltBike Yukon 750 and Magnum models.
A Pace 500 owner hunting a replacement is therefore shopping in the same aisle as an NCM Moscow owner, and the checks that decide fitment are the same for both.
The recorded spec sheet, checked against itself
The core arithmetic is simple. 48V nominal times 14Ah gives 672Wh, which matched the factory pack capacity on the listed bikes. The recorded 25A BMS allows about 1200W of continuous draw at 48V (25 amps times 48 volts), and every motor in the title's own 350W to 1000W band sits under that limit.
A 350W motor draws about 7.3A, a 500W motor about 10.4A, a 750W motor about 15.6A, and the band's 1000W top about 20.8A. Budget listings often pair a big motor claim with a BMS that cannot feed it, and this one did not make that mistake.
That is worth stating because the old version of this article got it wrong in the other direction. It claimed the BMS would throttle a motor beyond 750W, but a 750W motor at 48V draws only about six tenths of the 25A limit. Its FAQ also gave a 250W to 700W motor band that contradicts the recorded title's 350W to 1000W.
The title is recorded listing data, the other figures were Walter-era prose, and this rebuild follows the title.
The rest of the recorded sheet: a 54.6V 2A charger in the box, about seven hours from empty on a 14Ah pack. Case dimensions of 390 by 104 by 65mm. A key-operated lock for the frame mount, a side-mounted LED charge indicator, and a USB output for a phone, with its amperage never specified.
What was never recorded: a cell model, a pack weight, an IP rating, any cycle-life source beyond a marketing claim, and any warranty terms. A BMS protects a pack from overcharge, deep discharge and shorts, but it cannot make damaged cells or an undersized charger safe, which is why the missing charger detail matters more than it looks.
Three checks that decide fitment on a Dorado Plus frame
Because the format is shared, fitment comes down to three checks rather than the badge on the downtube. First, size.
The recorded case measured 390 by 104 by 65mm, and an integrated pack has to sit inside the frame cavity with the cover closing over it. Pull the old pack and measure it, or read the label. A few millimeters of height is enough to stop a battery cover closing, and a return shipment costs more than ten minutes with a tape measure.
Second, the base connector and mount. The Dorado Plus slide-in base carries both the power contacts and the locking mechanism, and the recorded compatibility list named the Aventon Pace 350, the Pace 500, the NCM Moscow and the Scrappeur MXC. The contacts and the cradle have to line up with what your frame already has, because rewiring a downtube connector is not a beginner job.
Third, voltage. The pack is a 48V part, and it belongs on a 48V system. A 36V bike will not accept it and a 52V controller may overdischarge it, so match the number printed on the old pack before anything else.
Once the pack is in the cradle, check that the key lock actually engages and that the charge port faces outward, since a locked pack you cannot charge is just a heavy paperweight in the frame.
Range on 672 watt-hours at both ends of the throttle
Range claims need a denominator, so here is ours. The em3ev 48V capacity table puts a 720Wh pack at 22 to 28 miles of throttle-only riding and 35 to 45 miles on light pedal assist. This pack holds 672Wh, about 93 percent of that row, which scales to roughly 20 to 26 throttle-only miles and 33 to 42 miles with light pedal assist.
Hills, cargo and cold weather all pull the real number toward the bottom of the band, and a heavier rider pulls it further. The old version of this article claimed 30 to 50 miles on flat ground without naming a riding regime, and that figure is gone.
Charging sets the rhythm rather than the range. The recorded 2A charger needs about seven hours from empty on a 14Ah pack, so a pack that is flat at bedtime will not be ready by morning. Top up after each ride instead of running it down, and the seven-hour figure stops mattering.
Lithium packs also age fastest when held near empty, so partial top-ups are kinder to the cells than full drains.
The one longevity claim on record is 80 percent capacity retention after 800 cycles, carried over from the listing era. Treat it as marketing until a seller prints a source.
For scale, 800 full cycles is a little over two years of daily full drains, and a commuter doing partial cycles stretches the calendar well past that. No cell brand was ever named, so there is nothing to check the claim against.
Replacing it now, with the details this listing skipped
The value position deserves a plain sentence. At 309 for 672Wh, the cost per watt-hour sat among the most expensive of the 324 packs on our comparison table, where the middle of the market runs noticeably cheaper.
The exact position renders live in the table's specs box. A dead listing does not change that verdict, it just ends the argument.
Anyone shopping the current Dorado Plus class should demand the details this listing skipped. Four items top the list: an IP rating printed on the page rather than the word waterproof, warranty terms written down somewhere enforceable, the charger included with its amperage stated, and a cycle-life claim the seller will stand behind with a cell brand named.
Add the case dimensions and a clear photo of the base connector, and a buyer can compare two packs on facts instead of photos. Sellers in this class who print all of those usually charge a little more per watt-hour for the privilege, and the arithmetic on our table makes the difference visible.
The current search results for 48V 14Ah Dorado-format packs change daily, which is exactly why the checks matter more than any single listing. Measure the old pack, match the connector, confirm the voltage, and then let price per watt-hour break the tie.
Frequently asked questions
Can you still buy this exact SDTYYP pack?
No. The listing page returned Page Not Found and the Amazon API rejects the ASIN, both probed on 2026-11-02. Equivalent 48V 14Ah packs in the same Dorado Plus case appear from other sellers, and the tagged search link shows what is listed today.
Will a Dorado Plus pack fit my NCM or Aventon model?
Fitment is decided by the case size and base connector, not the brand. The recorded pack measured 390 by 104 by 65mm, and the same format serves the NCM Moscow family, several Addmotor, Surface604, VoltBike and Magnum models, plus the Aventon Pace bikes named in the listing. Measure your old pack before ordering anything.
How long does a 14Ah pack take to charge?
About seven hours from empty on the recorded 2A charger, from simple arithmetic: 14Ah divided by 2A. A 3A charger would cut that to under five hours, but no faster charger was ever specified for this pack, so treat any bundled charger's amperage as a buying criterion.
What motors can a 25A BMS run at 48V?
About 1200W continuous, from 25 amps times 48 volts. That covers the whole recorded 350W to 1000W motor band, with headroom for the extra current a motor asks for during acceleration and near-empty voltage sag. A BMS is a protection layer, not a power source, so the cells and wiring still have to be up to the job.
