Battery Selection Guide — Which Voltage & Capacity?

36V vs 48V vs 52V — which battery for your kit and riding style?

Battery Selection Guide

Voltage First — Match Your Motor

| Motor | Correct Voltage |

|-------|----------------|

| 250–500W hub motor | 36V |

| 750W BBS02B | 48V (or 52V for extra speed) |

| 1000W BBSHD | 48V or 52V |

| 1500W hub motor | 48V |

Using a 52V battery on a 48V system is legal and safe — it gives you slightly more top speed and better hill performance as the battery discharges.

**Never use a 48V+ battery on a 36V system.**

Capacity — How Far Do You Ride?

Range depends on: battery capacity (Wh), terrain, rider weight, assist level, wind, temperature.

| Config | Wh | Typical Range |

|--------|-----|--------------|

| 36V 15Ah | 540Wh | 50–70km |

| 48V 17.5Ah | 840Wh | 80–110km |

| 52V 20Ah | 1,040Wh | 100–130km |

| 52V 25Ah | 1,300Wh | 130–170km |

*Range at PAS 3, flat terrain, 80kg rider, 20°C.*

Grade A vs Samsung Cells

Grade A cells are consistent, safe, and carry a 2-year warranty. They're what most OEM eBike brands use.

Samsung 50E / LG M50LT cells are better in two specific situations:

  • **Cold weather** — lithium capacity drops in winter; name-brand cells retain more capacity at 0–5°C
  • **High discharge** — if you run sustained high-power (BBSHD 30A config), premium cells handle heat better
  • Form Factor — Where Will the Battery Live?

  • **Downtube mount**: Cleanest look, lowest centre of gravity, best for trail bikes
  • **Shark pack**: Best if you need to remove the battery frequently for charging or security
  • **Triangle soft pack**: Maximises capacity in the frame triangle — great for tourers and cargo bikes
  • **Rear rack**: Only for commuter / cargo builds — adds weight high up, affects handling
