A few others have confirmed that it will work in terms of physical size, and I'd like to call attention to the discharge current ratings. For example, the 8 amp hour battery is only rated for 8 amps continuous use. In round numbers, at 12V, that's only about 100W per battery. When running on battery power, the 1500va ups would be limited to 200W continuous. I'm not sure if the BMS will enforce the current limit or if it will output more at the expense of longevity, but limiting a 1500W unit to around 200W doesn't seem like a good investment. Other batteries with the same chemistry but a different amp hour capacity and brand that have significantly higher continuous current ratings are available. It wasn't quite enough to bring the ups back up to its original wattage rating, but it was close. Of course, those batteries are a lot more expensive, so that's something to think about.
It is recommended that lithium batteries be charged with a special charger. Before I could use them, the seller patiently explained how to use them. Now I've connected them in a series and used a 58 to control them. Charger with a voltage of 4 volts and a current of 50 amps. It has a great effect.

According to what I've read, chargers for LiFePo4 batteries should be made specifically for them, rather than using a lead-acid battery. Charger for acid. If your existing marine batteries are LA, SLA, or even AGM, check to see if your boat's charging circuit is capable of charging LiFePo4. I bought this battery for a travel trailer and also bought a specific LiFePo4 charger rather than using LA chargers I already had, but the trailer doesn't have an alternator (or a generator). I do, however, avoid "trickle charging" from the tow vehicle by disconnecting the battery with a kill switch while towing, which is a situation that may be more similar to your marine application. It's possible that this is excessive, but for $900, I'm not willing to take any chances.

The item was delivered on April 7, 2021, and it no longer works, so it cannot be returned.
The Amazon predicted that it would arrive much sooner than it did. Before installing them in my main solar system, which powers my refrigerator, Internet, furnace blower, computers, and other items as needed, I charged them each with a LiFePO4 20 Amp charger. I'm prepared for any commercial power outage that lasts longer than a couple of hours. They should last ten years at the very least. So far, there have been no issues. br>br>July 2021: br>br>July 2021: br>br>July 2021: I purchased two more for my backup solar system, to replace a much larger brand. The two new ones are just wide enough for two people to fit in. This gives me 400 Amps of power replacing a 200 Amp battery at the same time I upgraded to two new 175 Watt panels for 75% increase at the same time I Even on cloudy/rainy days, the changes have provided me with ample power. There is a chance that more power outages will occur as a result of the drought in California, as hydropower generators will be unable to operate due to a lack of water. I've now used an extra 1000 Watt inverter I had in storage to set up the older panels and battery in a third system for emergency power needs. If my house doesn't fall down, I'm ready for the BIG ONE.
200Ah. I placed my order on May 11th and received it by 7 p. m. on May 15th. Batteries arrived very quickly. br>Each battery had between 13 and 14 cells when it arrived. 23 and 13 are two numbers. It had a voltage of 25 volts and seemed to be well built. br>The packaging was excellent. I used my own cables because each battery came with two cables and extra bolts. br>I did a bit of charging on each one separately so that each cell had exactly 13. The circuit is open at 51V. br>After that, I connected them in series and replaced my old, weak 415Ah AGMs. br>I charged them for another 4 hours at 55 degrees with the charger set to 40 amp bulk and 10 amp absorb. 2 volts until the float is reached at 2 amps. The voltage dropped to 53 volts after a while. 1 o'clock in the evening br>The terminals did not emit any heat or warmth during charging. br>Overnight, I left on my desktop gaming computer, 65-inch TV, a 3-D printer printing overnight, a large Kenmore refrigerator, ran the water pump, and microwaved a large cup of coffee several times, including in the wee hours of the morning. 450 watts drawn on average throughout the nightbr>pre-dawn readings are 52.

They appear to do exactly what they say they will. br>In our email correspondence, the seller was extremely helpful. br>I strongly suggest this seller RcLithium and the product Lossigy. a big plus! br>br>Recent changes: br>br> The second set has arrived, and they are now connected in parallel/series (48v 400ah) as shown in the last photo.
December 18, 2021br>br>The original battery I ordered appears to have a minor issue with reaching its maximum storage capacity; it's possible that my charger is the problem, but I haven't had the opportunity to fully test the system yet due to my frequent travel every two weeks. I'm running a 12v 4kw system that I designed to run all of the necessary items in a power outage (Puerto is known for its power outages, which usually last 12 hours), I run (2 deep freezers, 1 refrigerator, internet, 3 televisions, 12 lights, and 4 ceiling fans) I've gotten 12 hours out of the 300ah battery, and the lowest voltage this battery has reached after such use is 13v. This battery gets a thumbs up from me. a decent charger 50amp to 100amp with voltage adjustment and 3 stage Charging, if using solar get victron smart charger 60 capacity of battery and it should last 2010yrs without any% This is my December 2021 update, and I'm happy to report that I now use these batteries for all of my 12v to 24v clients. br>br>*Old review from when this item was purchased
This item could be shipped to Puerto Rico. , with the help of UPS. That made me extremely happy. br>br>The wording and specifications of this battery make me very nervous. br>br>200amp Charging is something I wouldn't recommend unless you're trying to set fire to your house. (50- Charger with a 100 amp output. br>br>This battery had 12 volts when I got it. I've been trying to get it to the 14. with 5dc of charge. As stated in the specifications, the voltage is 6 volts. It can go up to a maximum of 13 points. I checked to see if it would hold an 8dc charge with the inverter turned off, and it did in less than 5 hours, showing 13. 6dc. This strikes me as odd. br>br>I have a 4kw inverter, and when I put a 200w load on this battery, it shows that 56amp was drawn from a standing fan and a flat screen TV. br>br>I usually use this with agm batteries, and it doesn't seem to draw as many amps from the battery, even when I'm using 400w. br>br>If anyone else has had similar problems, please let me know. br>br>Perhaps the battery was defective.
This is not going to work. There has been no contact with the seller. I attempted to contact the seller but received no response. They don't respond at all.
UPS delivered the two 300AH batteries ahead of schedule, and shipping was completed in just four days (at a cost of $70). 00 expedited shipping) The product arrived in excellent condition. I used two of these to replace six 235ah 6v AGM golf cart batteries. They're mounted on a Magnum MS2812 inverter, which provides power to a fiber network system when the power goes out locally. We now have roughly three times the life of the previous batteries. When we tested the AGM cells, we got about 8 hours of run time. Now with two 300AH batteries I tested for 28 hours and batteries still had over 80% left. I wasn't sure it would work out when I ordered it, but I'm very pleased with everything. This is an excellent purchase for us. Thank you Junson, and I look forward to many years of trouble-free service.
I just got back from a week of boondocking with my 200ah battery, and it worked flawlessly. We had a couple of days with very little sunlight, but it was enough to keep us going. When the battery arrived, there was some shipping damage to the case, which was a minor issue. The customer service was excellent. I decided to try and fix the case. So far, everything has gone well after a week. When I returned home, I discovered a 10-amp charger on my doorstep, courtesy of Customer Service. I like to think of myself as a Happy Camper.
