World's First Powersport Battery with a FULL Battery Management System (BMS) including Over-Discharge, Over-Charge*, Thermal Protections and Cell Balancing. RE-START TECHNOLOGY: The RE-START Battery intelligently monitor its status; if it senses over-discharge it will put itself into a sleep mode, yet saves enough energy to allow you to RE-START your vehicle. Simply press the RE-START button on battery. (A Remote RE-START Button will soon be Available so you can activate the RE-START feature without accessing battery.) LONGER LIFE: Up to twice the lifecycle of lead/acid, and other Lithium batteries due to full Battery Management system. HI POWER: Up to 2 Times the Cranking Amps of similar sized lead/acid batteries. Better Starting and higher voltage at start-up. ULTRA LIGHTWEIGHT: Up to 70% lighter than equivalent lead/acid battery. Up to 15 lbs in bikes or 40 pounds in some Race Cars. Carbon Fiber costs thousands to lose a pound of weight; with our LiFePO4 battery a few hundred dollars will lose roughly 8-15 pounds and offers better starting and handling! NEW 4 Terminal Design allows easy installation in any vehicle. Fits right or left hand Negative or Positive connections. No more looking for the correct Terminal locations in certain bikes. LOW SELF-DISCHARGE: The RE-START Batteries do not self-discharge like Lead/Acid Batteries. They can hold a charge up to a year provided there are no "Parasitic Drains" (accessories that draw power when bike is off, i.e. alarms, ECUs, GPS, heated grips, and other accessories the vehicle might have). Please Note: if you own an older classic bike from mid 1980s and earlier you must update the charging system to a modern solid-state voltage regulator. Damaged or excessively old voltage regulators can over-charge and damage lithium batteries and cause smoking and melting of battery. This is NOT a fault of the battery! ***USE A LITHIUM ION CHARGER TO AVOID DAMAGING THE BATTERY***
