Party Speaker Lithium Battery

Ordered for ecoxgear ecoboulder pro, fits and works out the box. Lighter than the original battery.

got this replacement battery for my ecotrek in place of the lead acid one…

i couldn’t in million years that it would be so light and last extremely long

the charge was pretty slow but that’s to be expected though the battery is amazing

best purchase i have made to the longevity of my device

I don’t know what to say, this is the most pleasant surprise, having a battery that last two days versus 3 to 4 hours I was shocked! I plugged it in charged it, it played two days before it died at medium levels. Highly recommended!

When I bought the Ecoxgear Boulder, it showed up brand new with a battery that lasted about two hours. I used it only for backyard parties so it was always plugged in. Two years later, I tried to use it without a 110 outlet and the battery would only last about ten minutes. I bought this new battery straight from the website. It showed up in about three days. I charged it without using it first. The first thing I noticed different from the original was it was already almost fully charged. After fully charging it, I left it on for a full 10 hours to test it. When I came home from work, it still had three out of four bars left on the battery indicator. Can’t believe this battery lasts so long compared to the original. But it will be much nicer with this new battery.

Awesome! I tried a lithium phosphate battery at same specs from Amaz*n and it would not charge. It actually started showing the bars on the indicator going down and depleting charge. The Ecoxgear battery is light. Has padding stops installed for perfect, snug fit. Charged about half the time of lead acid standard batt. I will replace the lead acid in my 2nd Ecotrek speaker for weight and longevity sake.
