ECO-WORTHYPortable 12V Lithium Battery, 20Ah LiFePO4 Deep Cycle Rechargeable Battery, Built-in BMS, 4000+ Cycles,Perfect for Outdoor Camping Fishing RV Marine Trolling Motor Fishfinder

Love how small and light it is! Plenty of amps to run 4 LED lights and 2 fans!!Thank you!

I bought this battery because of its uniques DC port on the top which allows super simple hook up to other devices. It did not disappoint!I found an adapter cable right here on Amazon to go from the DC5525 port to my device, and boom! Instant connection.Charging was easy with a 10A smart charger.Design is nice. Price was good. What more could you ask for?

I have 2 of these for an inflatable fishing boat that I can mount a small motor on the back. I get a solid 3-4 hours of none stop power and once the first one runs out, I switch to the second to head back. I charge them with some small solar panels, which does take several hours but so far the system works great!

First battery arrived DOA (no power output/unable to take charge), but the return was simple and the replacement was in hand within a week. The battery's size and smooth case sides makes it a little tough to grasp unless you have big hands - a handle would be a nice addition. The new replacement appears to work well. Will it perform well over time? I have a couple of the 100AHr batteries from this brand that are working well.

Perfect size and weight to power the booster antenna and phone when confined to our tornado pod in emergency situations.

The first thing to know is this battery doesn't act like the lead acid family of batteries. with that in mind, do your home work and study up on the characteristics of a lipo 4. they are lighter, charge quicker, and charge thousands of times. They also are shipped drained for safety. when you receive it, it is drained you need to charge it. occasionally they won't recharge, and you need to contact the company as I did. They immediately sent a replacement. i am pleased with my purchase and the seller.

Before I begin let me just state that I'm an electrical engineer. I hooked this up to a small winch motor. I ran it for about a minute drawing 20 amps after which the battery started smoking. I turned it off but too late the battery was toast. The over discharge protection never kicked in, and no it's not in a tripped state. Just to make sure I hooked it up to a 15V current limited power supply which would reset the trip had it been tripped. The spec doesn't say what the maximum continuous power dissipation is, but clearly, I exceeded it. The maximum discharge current rating is 25 amps for this battery but probably that is a transitory spec rather than a continuous rating. In hindsight I need a bigger battery for this application, but the spec sheet didn't really help in that determination. Anyway, the over discharge protection should have avoided damaging the battery. But it didn't. So, I basically wasted my money. I reached out to Eco-Worthy via Amazon, but they have not responded after four days.

Excellent customer service. I appreciate great customer care. Eco-worthy has excellent customer service. I will definitely buy from eco- worthy again. Quality product, but most importantly that stand behind their products.
