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

I was pleasantly surprised, this battery appears to actually have a 20ah capacity as advertised. I also appreciate the case since it feels more durable than my bioenno. Only thing I would change is built in covers for the terminals.

Fast delivery and works as described. Lightweight and space saver.

great battery for tight spaces, currently using it for my forward facing sonar and it has last 15hrs before needing charging

Sometime you just need a basic battery without a fancy display, bluetooth, wifi, on/off swtich, electronics.This battery is always ON, and does not need a power converter to generate 12v. I'm using it to occasionally power a 12v fridge. It would be great to run a dash cam, a 1 hour charge at 20 amps when the engine is on would power a dashcam for a week.This is LiFePo4 battery, which is less energy dense, but also less likely to catch fire compared to Lithium Ion batteries. I plan to keep this in my car, and a Lithium Ion battery sitting in a hot car would worry me. Keeping batteries at a lower state of charge (below 80%) also minimizes the risk of fire.I have a teardown video on youtube if your interested. This doesn't seem to have short circuit protection, the manual states it can do 75A for 10 seconds, and short circuit cutoff kicks in at 500A. The internal wiring is 12awg, rated for 25A, so there's a risk of melting or smoking something. I added a fuse inside the battery case for added safety.

Great for power wheel 12 volt update. Hour runtime.

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!

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.

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.
