Extra Small & Light - Lithium battery is only one-third in weight of lead/acid battery of same specification. But you donâ??t need to worry about that there will be too much space empty and make the lithium battery rocky during the riding, we will add the fireproof foam to wrap the lithium battery and make sure it is 100% fit in the battery tray. Â Extended Cycle Life â?? lithium battery is expected to see 2000 and above cycles in testing. In contrast, even the best deep cycle lead acid battery is typically only good for 500 cycles, and some worse 300 cycles only. Lithium battery has 5 times longer life than lead/acid battery. Â Extra Safe â?? not easy to explode or catch fire even in an extremely testing environment. And here are some testing that we made to damage our battery cell in different ways, by burning, needle putching or huge weight pressing, and our lithium battery is just broken, but will not explode and catch fire. Smooth Discharging â?? With the application of different amount of discharge current, lithium battery can still discharge smoothly at the same temperature. Â Hight/LowTemperature Resistance - Lithium battery can work normally at the temperature of -20â??ï½?+75â??,and its peak value of electro heat can reach 350â??ï½?500â??,which the traditional battery only reach around 200â??. Â Eco Friendly â?? pollution free; NO acid, NO lead, NO heavy metal. Â Energy Save â?? low self discharge, can sit up to 1 year without maintainance because only 1-3 % power will be lost monthly. Unlike the lead acid, if you didnâ??t use it, then you must need to fully charge it 1 time per month. Â Fast & Efficient Charging â??Lithium battery can be fast charged to 100% of capacity. If your charger is powerful enough, lithium batteries can also be charged insanely fast, maybe 1 hour can make your batteries fully charged. This can save you hours of time. Unlike with the lead acid batteries, they can be charged in 1C current maximally, so normally it will take more than 10 hours to fully charged them.
