(10 customer reviews)

Price: $1,299.99

CONSISTENCY – We know the importance of maintaining the consistency of each marine battery, So we will test all the lithium battery Voltage and Internal resistance Voltage, the deviation less than 0.01V Resistance, the deviation less than 0.02mΩ. And balance all rv battery to ensure that the internal resistance, voltage and capacity of automotive battery are completely matched and balanced before delivery. This process is very necessary.

LONG LIFE – The typical estimated life of Lithium motorcycle battery is 10 to 15 years, and 4000 to 6000 charging cycles. The charging cycle is the entire service cycle from fully charged to fully discharged to fully charged.

EASY TO ASSEMBLE – 3.2V 200AH deep cycle solar battery is easy to install, including the required golf cart battery, connecting piece, screws, no professional knowledge is required, and it can be assembled in 10 minutes. And One lifepo4 battery will come with one set bus bar and bolt(e.g.,If buy 4pcs battery, we will send 4pcs cells with 4 sets busbars and bolts)

CERTIFIED SAFE – Grade A 200AH lithium rv batteries with Multi-Protect Safety System, ensures your safety and the protection for the lithium iron phosphate battery uses. (No leaking problem) WIDE RANGE OF

APPLICATIONS – Engine start battery, electric bicycle/motorcycle/scooter, golf trolley/baby stroller, electric tools, solar and wind energy systems, RVs, caravans, backup systems and UPS, Flashlight LED emergency light.

Lithium offers several performance benefits versus its sealed lead acid (SLA) equivalent .

A lifepo4 batteries capacity is independent from the discharge rate and provides constant power throughout it’s discharge.

The degradation of a lifepo4 battery cells at a high temperature is significantly reduced in comparison to SLA.

Lithium has ten times the cycle life as SLA at room temperature. Even at an elevated temperature, lithium still has increased cycle life.

10 reviews for ninthcit 3.2V 200AH LiFePO4 Deep Cycle Battery Cells with Iron Phosphate, Grade A Replacement Automotive Lithium

  1. CTfan

    I purchased four of these to power an electrified sailboat. The cells arrived when promised and all the cell voltages were within spec. Would recommend these cells.

  2. brandon

    Packaging was nice, all looked new, if they were used I couldn’t tell it. Arrived already balanced. These are expensive so we rely on reviews for these things and it seems these were as advertised.

  3. Carrol W.

    My 8 cells arrived today, 4 in each of 2 shipping boxes. The cells were in individual boxes with a protective bag around them. The terminals were protected and there was foam in each cells box. Each set of 4 cells came with 9 nuts and 8 thin bus bars. For charging and discharging I will double the bus bars. But it will also give me the opportunity to top balance them with the bus provided. The 8 cells all looked to be grade a new cells and were within. 01 volt of each other. Both shipping cartons had 4 cells in it and were well protected on the outside. They arrived ahead of expected delivery date. The only improvement I could see would be thicker studs on the batteries. Overall I definitely pleased with these batteries and in the future will purchase more.

  4. Grhoads

    Came in as advertised… I ordered 8 cells and all but 1 came in at 3.3V, the other is within spec at 3.29V. I am not sure why they use small screw in posts on these cells, but they seem a little flimsy and very easy to strip. I ordered better bus bars than the ones shipped with these cells and will make some myself out of copper due to how I have to position them on my boat. Very satisfied so far but will report back if there are any major issues.Going from 4 AGM batteries at 300 pounds and 160 usabe aH to this setup of 8 cells in a 4S2P configuration weighing 96 pounds and 450 usable aH. Complete game changer!

  5. Jon

    The media could not be loaded.  Very impressed with the fast shipping. Received in CT within 8 days. Everything was well packed and the battery is performing perfectly. I have cycled it a handful of times and drawn a full 200Amps each time. I’m running a 55 lb Newport vessels thrust trolling motor that draws around 44 amps on full speed on an old town canoe. I get 4-5 hours consistently. Amazing battery. Highly recommend. Also, I have connected it to a 1500w inverter to run my home Fridge in case we have a power outage.

  6. Doug

    Cell quality seems very high. Voltage was very close between the cells but I top balanced anyway. In the process of a low draw load test, we’ll see how that goes and perform a high(ish) load test after that…. but so far it’s looking good.Update: I’ve performed several high load tests using a 1500 watt space heater (through an inverter) and the cells deliver the advertised 200AH every time (slightly more actually). These truely are an excellent value, 2X the power of Battleborn and you can build one for $750 or so depending on the BMS that you choose.

  7. Tom Bristol

    Was on the fence for a couple years and realized the benefits over a standard lead acid battery at this price point far exceeded the negatives. I went from a filled box of 4 lead acid batteries weighing 70lbs to a single battery weighing in at under 45lbs. Usable capacity more than doubled as did the charge rate. All cells were VERY WELL PACKAGED and arrived at near the exact same voltage so no balancing needed to occur. We’ve been using them for the last month on our travel trailer and they have been great! I would highly recommend them!!

    Note: as of Jul 2021, NinthCit is selling a cell with a different terminal configuration from the LifePo4 cells I reviewed here (see my picture). My review based on the previous terminal configuration: The 4 prismatic 200ah 3.2v cells we received (i.e., terminal construction, tags, bus bars, nuts, etc.) look just like the cells Ninthcit has posted in their Amazon ad. Received these batteries in KS 9 days after ordering. They shipped from CA. Well-packed in new condition with an intact QR code on each battery. There was white, protective insulating tape still wrapped around all the terminals. Measured a .009v delta on the batteries as received. Still did an active top-balance at 3.60v. Delta from 95% SOC to ~20% SOC while under a 100a load was approx. .015v. After a few discharges/charges the no load delta has settled down to .001v to .002v (passive balance off). Produced 200ah on several load tests. Very pleased with these cells!

  9. ScoobyDoo

    I was very skeptical when I saw these on Amazon because often battery claims for LiFePO4 fall short. I’m very glad to say these were as advertised. They arrived looking like brand new cells and flat as a pancake on all sides, no puffing anywhere. The initial voltage was precisely 3.330 on all 4 cells. I then top balanced them which they did with flying colors. Then I ran a discharge capacity test from full charge 3.65v to 2.5v per cell on a DL24P at 10Amps and got 123Ah and right at 1500wh. Excellent batteries imo.

  10. SomeGuy

    I got just over 100% of the advertised capacity from these units and after a dozen or so discharges they are perfectly balanced (thanks to BMS) and working exactly how I wanted. Thanks!
