12.6V 3.3A Lithium ion Battery Charger for 10.8V 3S Lithium Lipo Battery Soft Start Precharge auto Cutoff Charging Percentage bar 20% 50% 80% 100% with 5521 Male Connector

Input: AC 100-240V 50-60Hz 1.0A Charger Output: 12.6V 3.3A Efficiency: 83% Charging Mode: Precharge (gradual start) - c.c. - c.v. - Cut-off Charge Display: 4 leds to indicate battery status (capacity levels 20%, 50%, 80%, 100%) Size and Weight: 120*67*38mm, 270g Protections: ocp, ovp, short circuit, reverse battery Safety and emc: ccc, ce, cTUVus, fcc, pse 12.6V 3S lithium ion battery charger, 3.3A at 12.6 volts, with slow-start function and state-of-charge indicator. The charger can be left permanently on the battery for maintenance. It uses energy-saving techniques and advanced charge precision. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. It suits accurately lithium-ion and lithium-polymer packs. It is programmed auto 4 stages (Ip-Im-Um-cutoff) charging process, designed for 3~25Ah Li-Ion/Polymer battery pack: Stage "Ip" is a pre-charge function for deep discharged battery pack, this is helpful for battery's cycle life. When the battery recovered by pre-charge small current, stage "Im" will give bulk current charging (up to 50W). Then, "Um" stage is followed, the output voltage is limited on C.V point, until the charge current declined to 0.4A (for 3A c.c) or 0.2A(for 1.5A c.c.). At this stage, the battery is charged completely, and the charger will cut off output automatic.

• 100-240 Vac, 1.0Arms 50/60Hz universal input. Output 12.6V 3.3A. Suitable for 10.8V/11.1V 3S lithium ion batteries.
• 4-stage charging mode: precharge-CC-CV-Cut-off. Precharge (soft start) with small current at the beginning when the battery voltage is below 9V, helping to extend battery life, and cut-off at the end, improving charging safety.
• 4 green LED segments bar charging percentage 20% 50% 80% 100%. Real-time monitor charging process.
• Multiple protections: undervoltage protection, overcurrent protection, overvoltage protection, short-circuit, reverse polarity. Multiple protections guarantee battery safety.
• Safety approval: CE cTUVus. Dimensions: 4.7*2.6*1.6in
