48V 1.5A Lithium Battery Charger with XLR Connector - 54.6V Output for 13S 48V Li-ion/Li-poly E-Bike - Perfect for Electric Bicycle Charging & Maintenance

To make your batteries last 10X longer, avoid using batteries below 35% and don’t charge above 85-90% Protections: Short circuit / Overload / Over voltage LED Display: Red: In charging state, Green: Full Charged Charge Mode: CC to CV Use: lithium battery charger Input Voltage: 100-240 V 50/60 HZ Suitable Voltage / Frequency: 90-264 V 47 / 63Hz Output Voltage: 54.6 V Output current: 1.5A / 3A（select） Power: 81.9 W Productivity: 80% Fluctuation / Noise: <100MV Working temperature: 0-40 ° C Storage Temperature: -20-85 ° C Working Nemi: 5% ~ 90% RH Storage Humidity li ion battery charger: 5% ~ 90% RH Housing material: PC Use and maintenance of the charger : 1. When charging, first connector to the battery, then connect to AC; after full, cut off AC, then pull the battery plug. If you pull the battery plug first while charging, especially when the charging current is large (red light), it is very easy to damage the charger. 2. LED display after turning green, then charge for 2-3 hours. 3. Please do not run out of battery power, then charger. Otherwise the battery cannot be protected or even damaged. 4. long-term shallow discharge battery, about 3 months, for a deep discharge, is the so-called re-lighting, which is conducive to the activation of long-term immobile material in the deep part of the battery. Luminous means that riding the controller battery undervoltage protection action 5. If your battery has not been used for a long time (2-3 months), please charge the battery beforeusing it. Make sure your battery is not broken. 6.Please use the charger in a dry place in time. 7.When you do not use the charger, do not always connect the power supply. 8.Please confirm your battery, Because it is used to charge the lithium battery. Do not use the charger on the LiFepo4 battery, otherwise the charger will be got incredibly hot.

48v battery charger, Input100-240VAC,50/60Hz 84W Output54.6V-1.5A, XLR-3Pin "1"means "＋", "2" means "-", “3”means ground, The plug's Diameter is 18mm, please check the size before order.

105℃ Output capacitor, global applicable AC Input voltage.100% full load aging test, Internal EMI filter, ripple minimum. The precision current between ±0.1A, the voltage tolerance is ±0.1V, absolutely not virtual marking.

The charger 48v, Built-in simply fan, with radiating fin surrounding the board, dissipating the heat through the shell, So some hot on the shell when charging is very normal, but it is durable.

The Charger protected Short circuit protection/ over current protection/ over voltage protection; red light -- charging, green light -- charge OK, it stop automatically when the battery is full.

Replace your broken charger or add an extra charger to charge in 2 locations without taking the original charger with you
