The Optimate 1 Duo Battery Charger is one of the best trickle charging systems on the market. This has been designed for performance power sport vehicles from small vehicles to large jet ski's. The Optimate 1 Duo Charger works on both lithium or lead-acid batteries. It will automatically save, charge and maintain both LifePO4/LFP and 12v lead-acid (STD, AGM, GEL) battery without any hassle or extra work. Simply connect your battery to the charger and forget about it. Optimate features an adaptive charging system that will adjust to either battery and condition of the battery without pushing any buttons. This provides a constant current of 0.6A so your battery will receive the trickle charge it needs to survive if put away in storage. There is no risk of overcharging! Using the Optimates Duo charger offers the best of both worlds as not everyone owns only one Lithium or Lead-Acid battery!
