Customer Success Stories
"In a truck camper, weight matters a great deal. My two, 100 Ah lithium batteries are half the weight of the lead-acid batteries with twice the power since I can use them down to around 10% or more of their capacity as opposed to 50% capacity on the lead-acid batteries. If I were to recommend RELiON batteries to a close friend, I would say that they're a good, safe bet that are far superior to any lead-acid/AGM batteries. We would never switch to another battery!"
- Anne Marie L.
"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.”
