Customer Reviews
Excellent upgrade for my boat!
I got the RB100-HP High Performance Marine Starting Battery and it's fantastic! My boat starts up so much faster now, and the power is consistent. Installation was a breeze. I'm so happy with this battery, it's made a huge difference to my time on the water. I'm definitely going to shop here again for my other battery needs!
Worth the investment
As a first-time buyer, I was looking for the best deal on a reliable battery. I picked up the 24V 100Ah Lithium Battery during their holiday sale, which saved me a good chunk of money. The free shipping on orders over $100 was a nice bonus. It felt like a solid value for what I got. The battery is performing as expected in my small cabin setup. I always check for deals before buying, and this one paid off.
Smooth order, great product support
I purchased the 12V 300Ah Lithium Battery for my off-grid cabin. The ordering process on the website was clear and simple. The battery itself arrived well-packaged and in perfect condition. I had a question about connecting it to my existing solar charge controller, so I called customer support. The representative was knowledgeable and patient, walking me through the setup. The battery has been performing flawlessly, holding charge even through cloudy days. It feels like a robust piece of equipment, and the long warranty is reassuring. Overall, a good experience from start to finish.
Solid battery, shipping could improve
I bought the InSight Series 48V Lithium Golf Cart Battery. It's a significant upgrade for my golf cart, plenty of power now. The installation was straightforward enough. Shipping took 5 days to reach Denver, which felt a bit slow for the price, but it arrived safely. I wish they had more detailed tracking updates.
Good battery, fast delivery
Ordered a 12V 100Ah LiFePO4 Deep Cycle Battery. It arrived quickly, within 3 days to my place in Florida. Works well in my RV. Satisfied with the purchase.
Consistent quality over time
This was my third purchase from RELiON, this time a 12V 80Ah Battery for a new project. I've always found their batteries to be reliable. My previous 12V 100Ah unit is still going strong after two years. The shipping is always consistent, arriving within a week. I keep coming back because I know what to expect in terms of product quality and service. No surprises, which is what you want with batteries.

Quick question on their military discount. Do you know if that applies to everything on the site or just certain products? Looking at one of the InSight series batteries.
Hey, thinking about grabbing one of their RV batteries. Anyone know what the shipping time to Florida usually looks like? Need it before my trip next month.
