Tenergy 36V 5A LiFePO4 Battery Charger

.red {color#F00;font-weightbold;}Features Intelligent charger designed for 12 cell LiFePO4 battery packs. Built-in cooling fan to ensure charger long service life. Safety protection Over Voltage ProtectionShort Circuit ProtectionOutput Reverse ProtectionCharging time Charging Time= (1.41 * Ah rate of the pack) / 2.5A charge currentBuilt-in IC to cut-off power automatically when battery is fully charged. LED indicators LED 1 = Red = Power OnLED 2 = Red = ChargingLED 3 = Green = Fully ChargedUser Instructions:Check the output plug of this charger and make sure it is not loose.Before charging, please connect the charger's alligator clips to battery firstthe "red" clip connects to the POSITIVE pole and the "black" connects to the NEGATIVE pole. After, connect the input power plug to the indoor power supply.The charger applies the intelligent charging method of constant current and constant voltage. The charger will automatically shut off when battery is fully charged. Unplug the input power supply then disconnect the output clips.When charger is not in use or finished charging, be sure to unplug input power supply.Indictor LED instruction "Charging" indicator shows "red" under normal charging state. It turns into "Green" when the battery is fully charged, the battery can be put into use at this time.The charging voltage of this charger is 36V, and shut-off current is .5A. It can only be operated when connect with not fully charged battery.Includes Battery Charger Power Cable ManualTechnical Specifications:Item 36V 5A Charger Model TN3605AL Max Output Power 120W Output Voltage 43.8V ??0.02Vdc Output Current 2.5A Rated Input Voltage 110Vac Input Voltage Range AC90-135V AC Input Voltage Frequency 5060 Hz Constant Current 5A??0.5A Constant Voltage 43.8V 0.3V Cut-off Current 0.5A Power Efficiency 90% (Vin=110Vac, rated load) Over Voltage Protection YES Software Over Voltage Protection The charger software limits the maximum output voltage to a level suitable for the connected battery system Thermal Protection N/A Current Limiting Protection YES (At CC Mode) Reverse Polarity Protection When output wires are reversely connected to the battery the chargerwill not operate and will work normally when DC wires are correctlyconnected Electric Strength Test Input-Output 1500Vac/10mA/1 min (No Breakdown) Isolation Resistance Input-ground 10m@500Vdc Isolation Resistance Output-ground 10m@500Vdc Leakage Current <3.5mA Safety CE/UL Compliant High Temperature Ambient Operating +40??C Low Temperature -10??C High Temperature Storage +70??C (Normal after recovery under normal temperature for 2 hours) Low Temperature Storage +40??C (Normal after recovery under normal temperature for 2 hours) Random Vibration 20Hz to 2000Hz 3 Grms 20 hours per axis Repetitive Shock 40g peak 3 orthogonal axes, 3+ and 3- in each axis, 11ms pulse width Thermal Shock -35??C to 75??C, <3min transition, 2.5 hours dwell, 200 cycle Drop Test BS EN60068-2-32:1993 TEST EDfree fall appendix B AC Wire Length 1m length DC Wire Length 1m length Net Weight 1.2Kg Dimensions 135mmX90mmX50mm (L*W*H) Output Connector Type XLR Connector Casing Aluminum Thecharger has been calibrated to take account of the voltage drop in theDC output cables during operation, to prevent the possibility of over orunder charging of the battery it is recommended the DC output cablesare connected directly to the battery without modification.Warning Only for use with LiFePO4 4 cell battery pack (If used with batterypack of less cells will cause damage to battery and possible personal injury mayoccur). Unplug charger after use. To prevent electrical shock, DO NOT remove casing Be careful of high-voltage inside charger. If failure happens, please contact us. Users and non-professional technicians are prohibited to open the charger! Keep charger out of children's reach. The charger and battery belongs in indoor environment with good ventilation and good cooling system, Do not expose to humid, high temperature, flammable, explosive gas environments. Do not bring charger along during transportation to prevent shock damage! Read the instructions carefully before using.Damage caused by improper use is not covered by warranty.
