Optimate Lithium 4s Battery Chargers

Optimate Lithium 4s battery chargers are ideal for high performance batteries that demand auto-fast, temperature controlled charging. The AmpMatic microprocessor adjusts current to ideal LiFePO4 charge curve to match the battery size/condition, for fastest and most complete charge. Simply connect the OptiMate Lithium 4s battery charger and it does the rest, no supervision required! Select the model best suited to your needs. Key features: * Automatically and safely charges, tests and maintains 12.8 V LiFePO4/LFP starter or deep cycle batteries as specified * Delivers maintenance charge, safe to leave connected 24/7 * Includes weatherproof battery lead and battery clip set * AmpMatic microprocessor adjusts current to ideal LiFePO4 charge curve to match battery size and condition for the fastest and most complete charge—smaller battery gets less, larger battery gets more * Optimate Lithium 24-7 smart inter-active maintenance prevents discharge from connected circuitry * Most advanced Lithium save mode will save battery from as low as 0. 5 V—continues charging if healthy, stops and warns if faulty! * BMS (Battery Management System) wake up mode safely wakes battery with integrated BMS protection out of sleep mode * No risk overcharging—totally safe for vehicle electronics, sparks suppressed and safe for long-term battery maintenance * Automatic shut-down if short-circuited or battery disconnected * Input: Global (100-240V 50-60Hz), high efficiency (CEC listed)—only the power plug type is different to comply with national/regional electrical safety laws Show Less
