How to choose the battery packs for bike lights?
  • Before replacing  a rechargeable battery for bike light,  you must know following data
    • What kind of light do you have ?   Halogen Light or HID light?
    • If  it is halogen light, what are  Voltage and  Wattageon your bike light?  6V or 12V?  5W or 15W?
    • If it is HID light, what are Voltage on your Light?   12V system or 14.8V regulated ?
  • Battery Packs for Halogen Bike Light
    • Halogen bike lights have two types:  6V or 12V.  Please make sure light bulb voltage before choose battery, otherwise, light bulb may burn out immediately
    • Halogen light has much lower cost than HID, and drain more energy from battery. NiMH battery packis suitable for all Halogen light.
    • In order to get better brightness and longer burn time, you can overdrive light up to 25% at voltage, for example
      • 6V halogen light  can use battery packs from 6V to 7.4V
      • 12V Halogen light can use battery packs from 12V to 14.8V
      • However, overdriving may reduce bulb life at same percentage  (Halogen light bulb is inexpensive)
      • Li-Ion battery pack can be used on halogen bike light, but you have to make sure PCB on Li-Ion battery pack can pass through higher higher initial current ( 3 time higher than normal current)
  • Battery Packs for HID Bike Light.
    • HID light three times higher brightness than halogen light at same power wattage, but much more expensive.
    • HID light must be fired between 9V -13.8V.  If battery voltage is higher than 13.8V , the bulb may burn out quickly.  So usually HIH lighting system has voltage controller to regulate voltage at 11V - 13V.
    • If  using 12V-13.2V NiMH battery pack  or 11.1V Li-Ion battery pack to drive HID light, you can drive any HID bike light on the market without voltage controller
    • Please never drive HID light by 14.8V  or higher voltage battery pack without voltage controller.\
    • Li-Ion battery is the most suitable for HID light because its less weight and higher energy
    • Usually, HID manufactures don't  list  all data on their battery pack , and they want to earn your money on replacement battery.  Doesn't matter.   you can email us  your light's brand name and P/N to  tech@batteryspace.com  , our engineer will suggest you a right battery pack immediately at 50% or more less cost.  Also, you can find battery data from below list.
  • How to Calculate burn time of battery pack for bike lights
    • Battery burn time is decided by battery capacity , e.g. mAh or Wh. Higher mAh  or Wh will provide more burn time
    • The time can be estimated as the following:
      • Burn time ( Hours) = Battery Wattage Hours (Wh) / BLight bulb Wattage (W)
        • here , Wh =  Battery voltage ( V) x  Capacity  (Ah),     1000mAh= 1Ah
        •  for example, battery pack ( 14.8V , 4.8 Ah) has 72Wh energy, can burn 13W light for 5.46 hour

 How to change connector and Cable

  • All brands bike light's connectors and cable are customized in special size , and can not be exchanged  (Trial-tech only supplies female cable)
  • You shall keep the connector in your old battery pack and install it to new battery modules
  • or  you can cut off your old connector , and install ourUniversal Water proof connector and cable
  • For HID light, you must connect cable in right polarity : positive to positive and negative to negative , otherwise, HID light can not be fired. 
  • You shall use Iron gun to solder junctions well, and use electric tape wrapping the the junctions.
