CHINS LiFePO4 Battery 12V 120AH Lithium Battery - Built-in BMS, 2000-4000 Cycles, Perfect for Home Energy Storage, Off-Grid

Your browser does not support HTML5 video.  Two reviews here, one for the 100ah and one for the 200ah smart battery with Bluetooth BMS (also see video for this model)We took our camper to a couple campgrounds that didn't allow generators and didn't have any other power hookup. Our standard deep cycle battery did fine for running the water and the lights but after a day and a half it was running quite low. I did a lot of research on battery banks and realized in a hurry you could drop a small fortune on a good sized battery setup.Based on some YouTube videos and other reviews I wanted to give this chin's brand a try. My plan was to run a test on the 100 amp hour 12.8 volt battery and see that the BMS works it takes a charge and the capacity is as stated. I charged up the battery with a specific lithium iron phosphate charger and then ran a full capacity test on it which yielded 104 amp hours! Just to be safe I charged it again did the same test after I let the battery cool and came up with 103 amp hours. I'm going to be purchasing a second one and then I'll put these in series to get a 24-volt system to use with my new inverter. This should allow us to run just about everything except the AC and I'm really excited for it! I do think you can save some money and still get a quality battery. I hope you found this helpful.

I purchased two 12V 200AH heated batteries from CHINS, which I installed beneath my Solar Power Management System in my RV Garage. I built a cabinet to stack the batteries, and installed a Shunt and Fuse to protect and measure the capacity of the batteries. So far, I am very happy with the batteries. CHINS customer support were very helpful, and careful to help me in anyway possible.

It arrived in tip top shape. Well packaged, and not a blemish on it. 13.14 volt on arrival. Charged to 14.28 with 10 amp lithium charger. Let set for 48 hours afterwards and never dropped below 13.54v. All hooked up to 500 watts of solar and performing nicely. I'll write another review in a few months for follow up. Chins customer service was fast, responsive to all questions, and courteous. I'm very pleased.

Used it to power my Minnkota 46 lb thrust electric boat motor. Fished for 6 hours, circled the entire perimeter of a 120 acre lake with no loss of power. Got home and put it on the charger, still had 60% of the power left (only lost 40% during the trip).

I have installed two of the 200 amp batteries in my truck camper. They work great. I am impressed with how they hold a charge and how fast they charge back up. These batteries are about 60% less cost than the Battleborn with the same warranty. Get them while you can.

I can say thanks to there info on charging specs. The same as arm in replacing. I have them in parallel with the other 2 12v 200amp battery,s for solar. Light weight after lugging AGM in and out if the under step place. AGM coming in at 102 lbs. I almost thought the battery's were empty cases weight of 25lbs. Big dif.The packing is very complete foam top bottom very well packed. Did not have to wake them up just equalize and charge.The big problem is the size .Mine came in at 12.75 in long there spec said 11.8 long. So double check your box. A extra day to modify . and fits like a glove. Eager to see how long they last so check back in 10 years or so.

You spend a lot for a 300ah battery, so expectations are pretty high.Right off the bat, EACH of the four 6 volt batteries I removed weighed more than this thing! Weight isn't that big a deal in a motorhome (compared to a motorcycle) but it is a LOT easier to lift in that the lead acid deals were to lift out.There is no requirement for special discharge/charge any more.The Bluetooth APP is not a problem, I had to email support as I didn't get a link. Within hours they responded with a link and I had the APP on my phone. The APP talks to the BMS, and you can see State of Charge, how many cycles the battery has been through, voltage in each cell, and a batch of other stuff.I am not an off-grid power expert or a super battery geek, my expectation was to greatly improve the house battery performance in my RV without becoming a super-geek, and it looks like that's been done. Would like to have TWO of these, but $$$... and just the one should meet our needs easily.We are happy campers! ;-)

If you are going to use this battery with a inverter, (how else would you use it right?), then you better get yourself an inverter with an over current protection of higher that 17 Volts. After charging this battery, the BMS started balancing the cells. I watched my battery meter showing surges of voltages as high as 17 Volts. (The documentation says to set the overcharge protection of the MPPT at 15 Volts to not "damage the battery.") Each time it surged to over 16 Volts, my inverter's over voltage protection would shut it down (at least I know that works now.). It only lasts for one second, but that is all it takes to shut down my clocks, TV, Computer, and Washing Machine. Each time I have to reset either the time or wash cycle of my washer. I had to plug all of my sensitive electronics into a UPS just to use them so I didn't have to worry about the power being disrupted prematurely. This should not happen. Also, I could never achieve a voltage over 14.1. Also, there is no Low Temp Protection after test. Not a big deal if you don't love in the cold.Other than that, it works fine and is a nice battery. LOL. The initial customer service contact, before I discovered this issue, was prompt, and I was able to continue a several email dialogue on the same day. However, I have not heard back from them after informing them of this issue. Maybe that's why they lowered the price by $30.
