DICHOU 52V 25Ah Shark Battery for E-Bike Conversions — Worth $335 in 2026?
The DICHOU 52V 25Ah Shark Battery Pack delivers 1300Wh for e-bike conversion kits rated up to 1500W, with smart BMS protection and broad motor compatibility — but a 52V vs. 48V voltage discrepancy in the specs must be verified before purchase.

How this e-bike scores for different riding styles
52V voltage provides higher power potential than standard 48V systems. Max discharge of 50A supports motors up to 1800W for strong performance, though the listing incorrectly states 48V in descriptions.
High discharge current (50A) and compatibility with 1500-1800W motors make it suitable for heavy-duty cargo applications. The 25Ah capacity supports sustained power delivery for loaded riding.
The 52V 25Ah capacity and 50A max discharge current can power off-road motors effectively. However, this is only a battery pack and needs to be paired with appropriate motor and frame components.
This is a battery replacement component, not a complete e-bike. It can support commuter builds with motors up to 1500W, but requires additional conversion kit components to function.
Compatible with lower power motors (150W-500W) suitable for casual riding. As a component part, it cannot be evaluated for leisure riding without the complete bike setup.
The shark-style battery is relatively compact at 368x95x150mm and removable with key lock. Portability depends entirely on the bike it's installed on, not the battery itself.
Our Verdict
The DICHOU SAIBIKE-R049-64826-0911 is a 52V 25Ah lithium-ion battery pack built for e-bike conversion kits in the 150W to 1500W watt range. At 1300Wh total capacity, it stores 2x the energy of typical 500-750Wh replacement packs, supporting sustained torque output for high-power builds over longer distances.
One critical spec issue: the product title states 52V, but internal descriptions reference 48V throughout. Voltage directly affects motor torque and top speed — a 52V system delivers approximately 10-15% more power than a 48V equivalent at the same amp draw. Confirm the actual voltage before ordering, since controller compatibility depends on it.
The DICHOU 52V 25Ah Shark Battery Pack uses 21700 lithium cells managed by a smart BMS that handles overcharge, over-discharge, overcurrent, and short-circuit protection. The 5-pin discharge connector provides more reliable current delivery than standard 4-pin designs. No hydraulic brake cutoff wiring is mentioned, so verify brake sensor compatibility with your specific conversion kit before installation.
No official weight is listed. Comparable 21700-cell packs at this capacity typically run 8-12 lbs — a meaningful addition to front or rear rack mounts that affects bike handling at speed. The included 3A charger requires 8+ hours to fully recharge 25Ah from empty; aftermarket 6A chargers cut that to roughly 4 hours.
At $335 for 1300Wh, the DICHOU battery undercuts comparable-capacity packs priced at $400-500. The removable key-lock design lets you charge indoors without moving the bike. For builders running Bafang mid drive motors or Voilamart, AW, and Ancheer hub motor kits, this is a cost-effective high-capacity option — provided the voltage specification matches your controller.
What We Like
- 1300Wh capacity (52V × 25Ah) stores 2x the energy of typical 500-750Wh replacement packs, extending range potential for high-watt conversion builds
- Supports motor kits from 150W to 1500W, covering the full watt range from budget commuter builds to torque-heavy off-road conversions
- Smart BMS protects all 21700 lithium cells against overcharge, over-discharge, overcurrent, and short circuits for longer pack lifespan
- 5-pin discharge connector handles higher sustained current more reliably than standard 4-pin designs, improving power delivery at peak watt draw
- Removable key-lock design lets you charge the 25Ah pack indoors without moving the bike, reducing both theft risk and cable management issues
What Could Be Better
- Title claims 52V but product descriptions repeatedly state 48V — a voltage gap that directly changes motor torque output, top speed, and controller compatibility
- Included 3A charger takes 8+ hours to fully recharge 25Ah from empty, versus 4 hours with a 6A aftermarket charger
- No official weight listed — comparable 21700 packs at this capacity typically run 8-12 lbs, adding significant mass to rack or frame mounts that affects handling
- No IP rating specified, leaving water and dust resistance unconfirmed for wet-weather e-bike riding
- XT60 connector limits sustained current to approximately 60A, which may cap peak watt output on the highest-power 1500W motor configurations

Frequently Asked Questions
Common questions about52V 25Ah Shark Battery Pack with Smart BMS Board for 0-1500W Ebike Conversion Wheel Kit - Lithium Ion Battery for Bafang Mid Drive/Front Rear Wheel Kit Hub Motor（25Ah）
Is this battery 48V or 52V as specifications conflict?
The title states 52V 25Ah but the description repeatedly mentions 48V throughout. Contact the seller to confirm the actual voltage before purchasing, as this significantly affects power output and compatibility.
How long does this battery take to fully charge?
With the included 3A charger outputting 54.6V at 3A, a full charge from empty takes approximately 8-9 hours. The 25Ah capacity divided by 3A charging current determines this duration.
What motors is this battery compatible with?
The battery works with motors from 150W to 1800W including Bafang, Voilamart, AW, and Ancheer conversion kits. The 50A max discharge current and XT60 connector support this wide power range.
Can I charge this battery while it stays on the bike?
Yes, you can charge it mounted or remove it with the key lock for indoor charging. The DC charge port connects to the included charger either way for flexible charging options.
What safety features does the BMS provide?
The battery management system prevents overcharge, over-discharge, overcurrent, and short circuits. These protections extend battery life and prevent damage from electrical faults during riding or charging.
