12V 30Ah LiFePO4 Battery,5000+ Deep Cycle Lithium Battery

I bought this battery for my Garmin fish finder on my fishing kayak. It’s very lightweight and fits perfectly in the YakAttack battery box. I’ve been using it for all my fishing trips over the past two months. I usually fish for more than 8 hours per trip—from 8 a.m. to 4 p.m.—with my fish finder running most of the time. This battery can last through more than four trips without needing a recharge, and it works GREAT. Highly recommend!

batteries are solid, no issues 6 months in.Runs heavy loads no issue. currently running with solar, dc charger and 3000 watt inverter.currently running continous server load.side note: not for automobiles, but able to jump start 4 cylinder vehicle.

Purchased this battery to replace a lead-acid battery in my pop-up camper. I've taken it on two trips so far and it's performed flawlessly. The first trip was for four days and I used my 100W solar panel to top up the charge each day and it never dropped below ~70% SOC. The 2nd trip was only two nights and without using solar it only dropped to ~50% SOC and that was without even trying to conserve power. So much better than having to worry about not over depleting lead acid batteries. The battery arrived nearly fully charged at 13.3 volts and took less than 30 mins to reach full charge. Very happy with this purchase!

I use batteries like this to run ultraviolet lights to attract insects. I set up a light over a bucket with soapy water where interesting insect might appear at night. This is one of several of these batteries I've used, and they seem to charge up well, hold a charge, etc.

Easy set up

Holy cow great fuzzy cheese Balls install this in my quantum edge three wheelchair. Had to cut out brace and remove fitting. Slid right in amazing performance compared to the old 2x12 V lead acid 55 amp power batteries. I started driving the past three days all day from in the morning around the neighborhood drinking coffee to the park in the afternoon for 1015 miles and then around the neighborhood in the evening putting 20 to 30 miles in the battery still show 100% I weigh 240 pounds and it saved a lot of weight on my chair and being paralyzed ‘ amazing not having to go home and plug up to a charger and sit there waiting to be able to get back out in life

Waiting to hear back from the seller, so will update review as needed, but battery arrived totally dead, sitting at about .2V as it arrived, checked with several multimeters. It's so dead that I cannot charge it, even my higher end 36V charger refuses to charge it and for good reason. Amazon won't do any customer service on this or accept a return or exchange, so beware any other buyers, you're dealing with a company in China for customer support, will update when/if they respond.
