Great product, solid cosutomer service!
I got this on sale for $150. For a self contained unit with BMS, heating, and bluetooth I am a very satisfied customer! The power button plate cracked when I got it and customer service sent out a new asap.
Epoch Batteries
Excellent products and good price last longer. I used until the power go down to 10% before charging to full again.
First Impressions All Positive
I purchased this battery for use as portable and backup power for amateur radio. It works very well for this purpose.
