Customer Success Story

"The RELiON batteries have a solid warranty and a stellar Battery Management System (BMS). Especially compared to lead acid batteries, which I’ve used in the past, the RELiON batteries are much lighter, which is crucial given van weight limitations. In addition to being very lightweight, they also come in a range of different, highly compact, sizes. They also use the safest battery chemistry: lithium iron phosphate, which is key if you’re sleeping next to them.”
