Got my Fuel Zero lithium batteries today

[bassdge]

I ordered them 2/15 at 7:58 PM and they were at the house when I got home.
12 v 50 ah with Bluetooth for $339 each to my door. Communicated with Harry(owner of business) on many occasions before pulling the trigger.

Blown away by size and weight even though I knew the specs. I had been moving some deep cycle batteries in my duck boat last weekend, so it was nice to pick up all three batteries at once

I recently saw these Fuel Zero batteries. How has their performance been?

How's the Bluetooth app? The link on their site for more into on it doesn't work lol

Just noticed this thread myself. Any chance we can get a photo of your smartphone showing the app in use?

Hope the OP is still around.

I wonder how good a job that 36v battery would do for a trolling motor battery? I’d love to hear how the OP likes these as well.

Works good, I had an issue at first but turns out I just didn't have the right link, They emailed it to me and took only a couple minutes to sync.
