YS YOSE POWER Electric Bike Battery Review: Is This 36V-52V, Up-to-20Ah Replacement Worth $259.69 in 2026?
The YS YOSE POWER Electric Bike Battery covers 36V, 48V, and 52V with up to 20Ah capacity, supporting motors from 250W to 1500W at $259.69—solid range for the price, but the included 2A charger adds 6–8 hours of downtime per cycle.

How this e-bike scores for different riding styles
The 30A max continuous discharge supports heavy-duty cargo motors up to 1000W. The 720Wh capacity provides sufficient energy for loaded hauling, making it suitable for utility bike builds.
The 30A max discharge current and compatibility with motors up to 1000W can power off-road builds. The 720Wh capacity provides decent trail range, but this is just a battery component.
The 48V 15Ah capacity supports leisurely rides with 31-112 mile range depending on assist level. Compatible with lower power motors (250-500W) suitable for casual riding, though it's a component not a complete bike.
This is a replacement battery, not a complete e-bike. It can support commuter setups with motors up to 1000W and offers 31-112 mile range, but lacks the integrated features commuters need like lights and displays.
Limited to 1000W motor compatibility and 30A max discharge. Performance enthusiasts typically need 1500W+ systems with higher discharge rates. The 48V platform is entry-level for high-performance builds.
The battery weighs approximately 15-18 lbs based on capacity and measures 14.45x4.37x3.54 inches. It fits down tube mounts but isn't specifically designed for folding bike integration.
Our Verdict
The YS YOSE POWER Electric Bike Battery is a multi-voltage replacement pack available in 36V, 48V, and 52V configurations with capacity options up to 20Ah—yielding up to 1,040Wh at 52V 20Ah. At $259.69, it competes well against similarly specced lithium packs in the $280–$340 range.
Motor compatibility spans 250W to 1500W, covering commuter builds, cargo e-bikes, and higher-torque trail setups. The built-in BMS manages overcharge, over-discharge, and short-circuit protection, helping preserve cell longevity across repeated charge cycles.
Charge time runs 6–8 hours with the included 2A charger, which is slower than the 4–5 hour standard seen with 4A–5A chargers on competing packs. Riders who commute daily will need to charge overnight rather than topping up between trips.
The integrated keyed lock secures the YS YOSE POWER battery to the down tube frame mount, and LED indicators display remaining charge on demand. However, the battery fits down tube installations only—rear rack mounts are not supported.
The 18-month warranty covers cell defects, and a 30-day return window gives builders time to verify fit and voltage compatibility before committing.
What We Like
- Up to 20Ah capacity (1,040Wh at 52V) supports 40–100+ mile pedal-assist range depending on motor wattage and terrain
- Compatible with 250W to 1500W e-bike motors, covering commuter, cargo, and high-torque trail builds
- Multi-voltage design (36V, 48V, 52V) fits a wide range of existing electric bicycle controllers and motor kits
- Built-in BMS with overcharge, over-discharge, and short-circuit protection extends lithium cell lifespan
- Integrated keyed lock secures battery to down tube frame mount, reducing opportunistic theft risk
- 18-month cell defect warranty plus 30-day return window reduces purchase risk for custom e-bike builds
What Could Be Better
- Included 2A charger produces 6–8 hour charge times, roughly 2–3 hours slower than packs bundled with 4A–5A chargers
- Down tube mounting only—incompatible with rear rack or triangle bag frame installations
- Sold as a standalone battery; motor, controller, frame, and display must be purchased separately, adding $300–$800+ to total build cost
- No fast-charge port or dual-charger input, limiting top-up options for multi-ride days
- Weight undisclosed in listing, making it difficult to calculate final e-bike payload capacity before purchase
