Selectable BMS Discharge Currents · Metal Enclosure
⚡ High-Performance Li-ion Pack
What BMS current do you need for a 52V battery?
The required BMS current depends on your motor power. For example, a 1000W motor typically needs a 30A BMS, while high-power setups above 1500W require 50A or higher to avoid current limiting and ensure stable performance.

Universal mounting support Tailored Power Delivery — This 52V 30AH battery is engineered with a robust metal shell and an intelligent Battery Management System (BMS) available in four continuous discharge ratings. Each BMS option is optimized to match specific motor power requirements, ensuring safe operation, extended cycle life, and consistent range. Choose the current that aligns with your controller and motor setup.
📋 How to choose the right BMS option:
- • Choose 30A → for motors up to 1200W, daily commuting, longer range, lower heat
- • Choose 40A → for motors up to 1500W, balanced performance and efficiency
- • Choose 50A → for motors up to 2000W, high-load or off-road riding
- • Choose 60A → for motors up to 2500W, maximum acceleration and power systems
🔋 Lower Current BMS (30A–40A)
Longer range
Lower heat generation
Limited peak power
⚡ Higher Current BMS (50A–60A)
Strong acceleration
Supports high-power motors
Reduced range
📏 Understanding range estimates: Range varies based on speed, terrain, rider weight, and throttle usage. Lower current setups typically achieve higher efficiency (Wh/km), resulting in longer range under similar riding conditions.

🛡️ Metal Case Advantage: The rigid metal housing provides superior protection against physical stress, compression, and impact — far exceeding standard ABS or shrink-wrap casings. It also aids thermal dissipation during sustained high-current discharge, keeping cells cooler and safer.
State of Charge (SOC) Guidance
For daily use: charge to 80–90% to maximize cycle life. For storage: maintain 40–60% (3.7–3.8V per cell). Never store long-term at <10% or 100% — this accelerates internal degradation.
Long-Term Storage Maintenance
If storing longer than 1 month, perform a shallow charge/discharge cycle (30% → 80%) every 3 months. This maintains lithium-ion activity and ensures the pack is ready when you need it.
