The battery that can outlive you! 50,000 deep discharge cycles! For the discerning DIY-er that appreciates safety, high power, and ultra long-life while taking advantage of Sodium-ion's innovative chemistry and environmental benefits. Prussian blue electrode sodium ion 12v 8S batteries are a responsible alternative to lead and lithium batteries. Goodbye rare earth materials like cobalt and questionable lithium supply chains. Unlike lithium, frequent rapid charging does not affect battery performance. These cells can be discharged down to zero volts and charged back up rapidly with no problems. Great for use in very cold environments as low as -4°F (-20°C).

Perfect for use with car audio, UPS, Data Centers, IT / Network closets, Telecom Base Stations, Landing Stations, Backup Power for on and off-grid sites, Industrial, and other mission critical uses. BattGo BG-8S balancer meter not included, sold separately > HERE.
