    Paid $30 for expedited shipping and boy did that work. I purchased the 200Ah model. It would be nice if it was a little more of the same dimensions of, say 2 group 27 batteries, but that isn’t a ding on this product since it looks like most of these are the same size. I built a new mount for the battery and it is working good.This battery is $200 to $500 less than the competitors, but appears to be a quality product. I’ll be installing a 2500w inverter this weekend and will update with my impression after our first trip using it.

    I received the battery in a good time frame. It was as described, you never know. I just got it so I haven’t had time to give anymore review. Very nice battery.

    I ordered this on a Saturday evening, it arrived the following Tuesday, super fast 3 day FedEx shipping, and the shipping was free on top of that! Arrived in excellent condition, double boxed, hard foam around the battery, excellent product build! Came charged to 13.1v. I have a LifePo4 RV converter so attached the leads and charged it to 14.34v in a couple of hours.All in all I am very happy with this battery! The build is excellent, not too heavy and the case is hard plastic and even looks very nice as well. Time will tell regarding how things work out but so far so good.Also, I received 3 emails from their customer service, one letting me know it was shipped, one saying they tracked it and to make sure it arrived in good condition, and the third following up to make sure I was pleased with the battery and to let them know if I have any problems with the battery. This seems to be a very credible company as per the feedback they have received so far. I wouldn’t hesitate buying another LifePo4 battery from them in the future!

    Came extremely quickly after ordering. Excellent price for the product. Haven’t plugged into our solar system yet and will update once I have some use on them.

    UPDATE: It took ten days including weekends and Thanksgiving to receive my batteries with the expedited shipping option. That’s pretty fast.I have not received my batteries yet but in the meantime I wrote support to get the specs I need to put into my EPEVER Triron 4210n charge controller. They were quick to reply. I thought I’d post the numbers for others that might need them. They are for one 200AH 12V LIFePO4 battery.

    Has a lot of power for the size. Being used for a van conversion with solar panels and we haven’t had any issues. I’m hoping it will have a long life in van.

    The packaging for shipment was impeccable, a double wall cardboard box with solid foam molded battery padding, with the battery inside a sealed poly bag. The attention to detail was excellent across the board.Interesting is the fact that in testing voltage, each battery registers its voltage separately, so it’s not necessary to remove cables to find each battery’s true voltage – smart battery indeed.Output voltage is flat during most of the discharge cycle. About 13VOutput voltage is higher than lead acid which keeps electronics operating longer.Higher output voltage reduces inverter current draw by approximately 10%.Can be charged faster. Up to .5C vs .2C with lead acid.Absorption mode is at the very end of charge instead of at a typical 80% for lead acid. This drastically reduces charge time.Can last many years (2000-4000 cycles) vs approximately 2-5 years (300 cycles) for lead acid.If I accidentally let it over discharge and the onboard BMS cut off power automatically, no harm done.

    Some how it arrived in 3 days. It was boxed with a lot of foam at the corners and the box itself was thick and strong. So far its working flawlessly, time will tell but the company has come through and delivered what I was hoping for so that gives me confidence with the battery. I would love to see an independent expert review of this battery on YouTube but if results come out the way I think they will, the price will go up. I’d say to take the chance and buy it if your looking for a 200 amp capacity battery.

    Just received and installed four 12 volt 200 amp hour batteries at our Camp that are supplied by our solar array. I’m more than pleasantly surprised at how much power these have. We used to run six 8d battery’s and these four blow them away. Be curious to see how long they last. They were shipped from China and arrived in 4 days. I can’t give them a high enough review at this point.
