Smart Charger (1.8A, 3 pin connector) for 24V NiMH / NiCd Pack -- UL/CE Listed

• Designed for safe charging 24V NiMH/Nicd battery pack with capacity > 1800mAh
• Built in IC to smart control charging status and keep battery charged fully and safely, which features with advanced functions are as the follows:
  • Charging current: 1.8A pulse current.
  • Detect Minus delta V ( > 6 mV/cell) to cut-off power when battery is fully charged.
  • Detect temperature rising rate. ( dT/dt)  If battery pack temperature rises too fast, (>0.5^oC/60S)the charger will reduce charging current.
  • Detect battery pack's max. temperature (T max.).  If pack's temperature >70^oC, the charger will cut-off power.
  • Over charge protection; Polarity reverse protection.
• This is very smart charger: just plug in and forget it.
• Charging terminal: 3 pin female cannon connector
• Pin 1 = Positive of Battery
• Pin 2 = Negative of Battery / Common with thermistor
• Pin 3 = Thermistor
• Included one 3.5" long of Temperature sensor(70C, BEC female plug)
• Included one  2 to 1 connector adapter, convert from 3 pin male cannon connector to standard female Tamiya connector & BEC male connector adapter 
  • Must attach standard female Tamiya end to standard male Tamiya end, charging terminal of the NiMh pack.
  • You must attach BEC male end to the included temperature sensor (70C) wire for the charge to operate (see pictures below)
  • Must buythe connector adapter (Convert from Standard Male Taimya connector to Mini Female Tamiya connector) separately if the 24v pack has mini male charging terminal
• Included Connector/Adaptor: BEC male to male connector (3.0", 22AWG)
• Use for connect BEC female connector with BEC female connector
• CE / UL listed

Specification:

• Input: 100~240VAC 50/60Hz 0.8A
• Temperature sensor: NTC R₂₅ =10 K    B=3960
• Dimension (HxWxL): 2.7"(69mm) x3.6"(91mm)x4.9"(127.22mm)
• Weight: 1.0 lb 3.2 Oz  (544 grams)

Operation Instruction:

• Connect battery pack to output connector and plug AC power source
  • Plug included 2 to 1 connector adapter to the 3 pin cannon plug of the charger.
  • Plug standard female Tamiya end of the 2 to 1 connector adapter to standard male Tamiya end, charging terminal of the NiMh pack
    • Must buythe connector adapter (Convert from Standard Male Taimya connector to Mini Female Tamiya connector) separately if the 24v pack has mini male charging terminal
  • Must Plugthe included temperature sensor (BEC female plug) to the BEC male plug of the included 2 to 1 connector adapter. Then locate the temperature sensor end to the middle top of the pack as picture shown below.
• Make sure battery polarity is connected correctly (Red wire is positive)
• After it connect the correct battery pack, the red LED will be on, shows that it is charging.
• After battery is fully charged, green LED will be on and it shows the battery fully charged.
• If the sensor is not connect, the LED will flash red/green indicate bad sensor.
• If everything is connect properly (no battery connection, but has ac power), the LED will stay Green

Warnings:

• Please don't use the charger for low capacity battery pack (<1800mah). Strongly suggestion to use Powerizer brand high drain rate battery pack. We are not responsible for any damage caused by charging other brand battery using this charger.
• Open voltage is at 38.4Vdc, Iout = 0.0A (no battery connected)
• Please don't charge battery pack which is not 24V or 24V with capacity < 1800mAh.
