Thanks for the replies. True about he the lifetime warranty, but the company has been around for 18 years. After comparing the Battle Born Specs, vs the Lion Energy, I decided that saving 30% was worth it. I know Battle Born is doing a great job at promoting themselves, heck you can't watch YouTube video without them partnering with anyone with a Youtube channel. Seems, Battle Born is eager to send out freebies to the YouTubers, but not pass any savings to the actual consumer. Like I said, they are doing a great job at promoting their product with little investment.
We I first stopped at the Lion Energy booth, they had rows and rows of batteries. When I returned, their stock was down to nothing. People were lining up to buy their batteries. Installing them was fairly easy. My converter can handle the lithiums, but will only charge them to 13.7v, lithiums can charge to 14.3v, so I will upgrade the converter.
Everyone knows the old saying "you get what you paid for", so time will tell if I made the right choice.
