ECO-WORTHY Portable 12V Lithium Battery, 12.8V 20Ah Lithium Iron Phosphate DEEP CYCLE BATTERY, Built-in BMS, 4000+ Cycles, Perfect for Outdoor Camping Fishing RV Marine Trolling Motor Fishfinder

Works really well. Used it with my FT 991A on SSB and FT8. I used it for 6 hours, constantly transmitting at high power and still had ~25% charge left after using. Works with a bunch of different connectors and easy to carry. Great value when it goes on sale. Feels more protected than EcoWorthy's other 20Ah battery.

I use an FT-891 from Yaesu for Parks on the Air activations. I can run the radio on 100 watts for 3-4 hours before the voltage drops down below usable voltage so it's a great run time It's a great small size that I can put anywhere. I love the quality of it - it feels well built, and the black and orange color is a great look. It's easy to use and carry around and charges quickly with a DC charger.

Very satisfied. I use the battery to power a 24lb thrust trolling motor on my kayak. When I initially mounted my trolling motor I was using a heavy 35amp hour lead acid battery. This eco-worthy battery is game changer. It is so light weight I carried it in a back pack to the kayak launch. It’s perfect for my trolling motor that draws about 15 amps on high speed. I cruised through the mangroves for about 40 minutes at full speed and when I hooked my battery up to a charger later in the afternoon it was still at 50%. I’m definitely going to buy another so that I have 2 with me and will still be lighter than my old setup.

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.

This little battery kicks ass I will be buying another

Super lightweight and small. This battery is super portable and convenient to move around. Having the screw head threaded posts made it super easy to hook up to. Currently using it in a portable power box that is able to charge my phone, laptop, and other devices. Highly recommend.

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!

UPDATE: Was contacted by vendor 11 months after purchase and shortly after my post here. They were concerned about my issue as reported. After several emails back and forth they have sent me a replacement; I received it yesterday. Their customer support was excellent and very friendly. I explained my situation and process and they were not hesitant at all to offer a free replacement. I am bumping my initial rating up from two stars to a full five stars largely due to the customer service and the replacement sent eleven months after purchase. ORIGINAL POST: ... Perfect size and fit for go-to box to power ham radio gear. Sad part is shelf life is terrible. Used three times over past 10 months and had to recharge from 0 volts each time. My other 7.2 Ah backup maintains a perfect full charge over same period. Very disappointed. I may have gotten a bad battery with an internal parasitic drain, way past return window.
