The SDTYYP 48V 17Ah is a Reention Dorado Plus style downtube battery built for 48V ebike systems. It's marketed as a replacement for the Aventon Pace 500, though the Dorado Plus housing is used across quite a few ebike brands. SDTYYP packs 65 automotive A+ grade cells into an aluminum alloy shell for 816Wh of capacity, with a 30A BMS managing everything. The listing does have multiple capacity options (13Ah and 17Ah variants are available), and this review covers the larger 17Ah version. It comes with a charger, a lock with keys, a built-in USB port, and LED power indicator.
If you're running an Aventon Pace 500 or another ebike that uses the Reention Dorado Plus housing, a third-party replacement battery is a nice way to save a bunch compared to buying from the original manufacturer. The SDTYYP slots into that gap at a competitive price per watt-hour, and 816Wh is a generous amount of capacity for a 48V system. This is a relatively new listing so there aren't any customer reviews yet to draw from, but the specs and form factor are worth looking at if you need a Dorado Plus replacement. See how it compares on price per watt-hour against other 48V batteries on our comparison table.
Specs and Value
The capacity math works out to 48V times 17Ah, giving you 816Wh of nominal energy storage. That's a solid amount for a 48V pack, and puts the SDTYYP into the higher capacity territory before pricing jumps significantly into the 20Ah+ range. Per watt-hour it works out to about 0.36 per Wh, which is competitive for a Dorado Plus battery designed for a certain mounting on certain ebike frames. Generic Hailong packs can sometimes work out cheaper per watt-hour, but they won't fit in the Dorado Plus mount unless you do some serious modifications.
Physical specs
The Reention Dorado Plus housing is an aluminum alloy downtube battery that is designed to bolt directly to the frame of compatible ebikes. The alloy construction is far better for heat dissipation compared to the plastic Hailong shells, and feels sturdier in general. SDTYYP states 65 automotive A+ grade lithium ion cells, which points to a 13S5P configuration (13 groups in series for 48V, 5 cells in parallel for 17Ah). There is a spring-loaded handle on the top to easily pull the battery off the frame for indoor charging or storage, and the whole unit can be locked to the frame with the included key.
SDTYYP doesn't specify the charge rate on the listing, but the included charger will bring the battery from empty to full. Based on similar 48V 17Ah packs with standard chargers, expect something close to 5 to 7 hours to charge from empty. The battery has a USB port for charging your phone while riding, and a four-light LED indicator that lights up when you press the button on the bottom, showing you how much charge is remaining.
BMS and motor range
The 30A BMS covers the standard protections: overcharge, over-discharge, short circuit, over-current, and over-temperature. At 48V with a 30A continuous discharge, you get about 1440W of theoretical power output. SDTYYP lists compatibility with 250W, 350W, 500W, 750W, and 1000W motors, which covers the vast majority of 48V ebike configurations. The 30A limit means you shouldn't push beyond 1000W consistently, but for most riders running a 500W or 750W motor, there's plenty of headroom.
SDTYYP highlights the use of "automotive A+ grade cells" which is their way of saying these are higher-tier lithium ion cells selected for consistency and longevity. Without a specific cell brand mentioned (Samsung, LG, EVE, etc.), it's hard to know exactly what's inside, but A+ grade cells from reputable manufacturers can still perform well and last through hundreds of charge cycles. The 65 cell count lines up with a 13S5P arrangement, which is a standard and proven configuration for 48V 17Ah packs.
Form Factor and Compatibility
The Reention Dorado Plus is a specific downtube battery housing that several ebike manufacturers use on their factory-built bikes. The Aventon Pace 500 is the most notable bike that uses this battery form factor, and it's the primary compatibility target listed by SDTYYP. If your ebike originally came with a Dorado Plus battery, the SDTYYP 48V 17Ah should be a direct physical fit, the battery slides into the same mounting rails and locks in the same position.
That said, physical fit doesn't always mean electrical compatibility. You need to confirm that your bike's controller expects a 48V battery and that the discharge connector on the SDTYYP matches your bike's wiring harness. For the Aventon Pace 500, the Dorado Plus is the factory form factor, so the connection should match. For other bikes using Dorado Plus housings, double check the connector pinout before ordering. SDTYYP offers email support through Amazon Messages if you have compatibility questions.
The aluminum alloy shell is a nice step up from plastic housings. It's more resistant to scratches and dings from trail debris, handles heat better during sustained high-power discharge, and generally has a more premium feel. The spring-loaded carry handle makes it convenient to pull the battery off the bike for charging indoors, and the security lock keeps it attached when you're away from the bike.
Real-World Range
With 816Wh on a 48V system, range potential is very good. Running a 500W motor on moderate pedal assist over flat terrain, you could reasonably expect 35 to 55 miles per charge. With a 750W motor and more aggressive throttle use on hilly terrain, that drops to maybe 20 to 35 miles. For the Aventon Pace 500 specifically (which runs a 500W nominal motor), riders should see solid range that comfortably handles longer rides and multi-day commuting on a single charge.
For daily commuters, 816Wh means you can likely go several days without charging if your round trip is under 20 miles. Even with a 30-mile round trip on moderate assist, you should get two days out of a full charge. The USB port is a nice bonus for keeping your phone charged on longer rides, especially if you're using GPS navigation.

What to Know Before Buying
This is a relatively new listing on Amazon and at the time of writing there are no customer reviews available. That means there's no real-world feedback on longevity, actual range performance, or customer support quality. SDTYYP does offer after-sales support through Amazon Messages, but without review data it's hard to gauge how responsive they actually are.
The lack of reviews is common for newer listings from smaller brands, and it doesn't necessarily mean the product is bad. The specs are solid, the Dorado Plus housing is a proven design, and 65 A+ grade cells in a 13S5P configuration is a reasonable setup. But buying a battery with no reviews does carry more risk than picking one with dozens of verified purchases. If you do go with the SDTYYP, test the battery thoroughly within your Amazon return window. Verify that it charges correctly, that the voltage readings are accurate, and that it fits your bike properly before committing to keep it.
One thing to consider is whether the charger specs match your needs. The listing doesn't specify the charger amperage, which could mean anything from a slow 2A charger (7+ hours to full) to a faster 3A unit. Ask SDTYYP through Amazon Messages before purchasing if charge time matters to you.
Who Should Buy This
The SDTYYP 48V 17Ah targets a specific audience: riders with ebikes that use the Reention Dorado Plus battery housing, particularly Aventon Pace 500 owners. If your bike uses this form factor and you need a replacement or upgrade battery, the SDTYYP offers 816Wh of capacity at a competitive price point with an aluminum housing that should hold up well over time.
The 30A BMS handles motors up to 1000W, the USB port and LED indicator add convenience, and the spring-loaded handle makes removal and installation straightforward. The main trade-off is the lack of customer reviews, meaning you're taking more of a chance compared to batteries with established track records. Keep your return window in mind and test early.
