New all in one Lithium Power Supply now available

Lithium Ion Batteries - more power, greater efficiency, longer lifetime. Lithium ion batteries are more powerful and provide more energy for high consumption than traditional lead batteries. They can be discharged up to 80 % compared to the traditional 30-50 % without damaging the battery, and are charged extremely fast, in down to 50 minutes for a 12 volt - 100Ah lithium ion battery.     

 + Fast charging        + Long lifetime         + Low weight          + Powerful  

Lithium batteries have a uniquely long lifetime of 3000 charge/discharge cycles. The batteries are compact and very light – switching to lithium can reduce the weight of your vehicles significantly.   Charging a lithium ion battery from an alternator is both efficient and fast compared to lead acid. The only requirement is a CDR Battery Separator or Converter between the starter battery and lithium ion battery.Lithium battery packs are built up by a number of individual lithium cells which must all maintain the same voltage for the battery to stay functional. Therefore, all lithium power solutions from Perpetual V2G have an integrated Battery Management System (BMS) that automatically balances the cells during charge, discharge and in idle mode. The BMS monitors the voltage and temperature of each lithium ion cell which influences the functionality of the battery. Our BMSs include an electronic MOSFET based safety breaker that prevents short circuits, for safe and reliable use.
​Just plug the lithium battery in, and you’re ready to go.
