If you bought LiFePO4 batteries from Amazon, you NEED to watch this.
In today’s video I break down what happens when battery companies refuse to honor their warranty because the battery was purchased through a 3rd party Amazon seller.
I recently discovered that some companies will not support or warranty their batteries unless they are purchased directly from their website — even if you bought them brand new on Amazon. I also found that Dumfume will not honor warranties through Amazon purchases.
So what do you do when you're stuck with failing 12V LiFePO4 batteries?
Instead of fighting multiple small BMS units inside four separate 12V batteries (what I call the “micromanagers”), I decided to tear them down and rebuild my system into a single 48V battery with one main BMS.
In this video I show:
• Why multiple small BMS systems can cause issues
• What happens when one 12V battery disconnects in a 48V setup
• How I’m rebuilding my pack into a single 48V configuration
• What you should check BEFORE buying LiFePO4 batteries on Amazon
If you're running a 48V golf cart, solar setup, or off-grid system, this could save you serious money and frustration.
