Review: Terrific Upgrade For RV and Still Ticking After 17 Months of Solid Use in a Range of Climates - Bought one in April 2022 and here's what I like most about the Lossigy LiFePO4 200ah battery: 1. Increased the electrical storage capacity on our RV by over 400%.* 2. 20% lighter than the 50ah wet cell bank it replaced.** 3. Fit perfectly in the battery box that formerly contained 2ea. 6V wet cells wired in series. 4. No problem with operation in temperatures down to 27F.*** 6. Still reliable and showing no signs of deterioration after 14 months of heavy usage. 7. Prompt and helpful responses from seller whenever I've had a question. NOTES: *The battery continues to put out 12 volts or more, even when remaining capacity falls below 15% (as measured by RV's coulometer). My 50ah wet cell bank, by comparison, would often drop below 12V when remaining capacity hit 30%. Useable capacity was therefore about 35ah whereas usable capacity of the 200ah Lossigy LiFePO4 is 170ah+. **Combined weight of the 50ah lead-acid battery bank that was replaced was over 60 lbs, or about 1.2 lbs per rated amp-hour. The Lossigy LiFePO4 200ah battery, by comparison, weighs in at only 48lbs. This equates to about 0.24 lbs per rated amp-hour - effectively less than 1/5th the weight per ah of the wet cell bank. ***We've camped in winter conditions and watched anxiously as temperatures on the surface of the battery hit 27F (as measured by remote sensor). The Lossigy battery never so much as hiccupped (though I wouldn't want to push it much lower than 27F). NOTE: Worth considering with an RV trailer is the fact that standard tow vehicles rarely come equipped with a tow-battery charging system capable of putting out greater than 8 amps. This means 10 hours of driving might put 80 amp-hours back into your trailer's 200ah battery. The solution is a DC-to-DC charger that can bump the charging current up to 20 amps or more (I installed a model made by Renogy, but there are others). Also, a fairly robust solar charging system (mine is combination of Dokio arrays and MPPT charge controllers rated at 460 watts total) can keep you off the grid almost indefinitely without relying on a noisy generator. UPDATE: Questions show up on desertcart from time to time regarding low temperature protections for LiFePO4 batteries. I think the only way to safely use these batteries when ambient temperatures are substantially below freezing is to provide some source of heat, such as rechargeable heat packs placed around the battery (see Dnaleao hand warmers, for example). Also, insulating the battery box somewhat (I've added foam packing material under and on the sides of my battery) helps. Last year when I submitted this question to Junson Bty (seller of Lossigy LiFePO4 batteries on desertcart), they answered: "When the battery is charged at an air temperature lower than 32 ° F, the lithium ion activity inside the battery decreases, which will lead to the decrease of charging efficiency with the decrease of temperature (this situation is similar to some animals entering hibernation in winter), but this will not cause damage to the battery. It is recommended not to charge at low temperature for a long time."
Review: Great quality - Use it daily. I have a small setup on my working van, just for microwave and coffee maker. It works well with a power inverter and it also helps me to work on remote places without electricity. Even my bigger 12Amp 120v corded Miter-saw. It doesn't even flinch

## Questions & Answers

**Q: Does the BMS automatically prevent low temperature charging?**
A: Dear customers, thank you for your question. Our battery working environment is as follows:
Operating temperature range
Charge: 32℉--113℉
Discharge: -4℉--140℉
Storage temperature: 10℉-122℉
Charging state: low temperature cut-off is 32 ° F, high temperature cut-off is 113 ° F
Discharge state: low temperature cut-off is - 4 ° F, high temperature cut-off is 140 ° F
Thanks.

**Q: Does 100 ah have low temperature charging cut off**
A: Thank you for your question. At present, all models of batteries sold do not have low-temperature cut-off function. It can only be cut off under the conditions of low voltage, high voltage, high temperature and overcurrent. Thank you.

**Q: Can you safely run these as headway power for car audio? Give me an actual answer not “boosting audio blah blah.” Don’t care I need answers.**
A: Thank you for your question. Our 12V 100A battery has built-in 50A BMS, and the max continuous discharge current is 50A. Please consider whether it meets your needs. thank you.

**Q: Can these batteries be recharged from my marine alternator?**
A: From what I've read, chargers should be designed specifically for LiFePo4 batteries, that is don't use a lead-acid charger.  If your existing marine batteries are LA or SLA or even AGM, maybe figure out the existing charging circuit on your boat is designed to charge LiFePo4 effectively.  I got this battery for a travel trailer and also purchased a specific LiFePo4 charger instead of using LA chargers I already own, but of course the trailer does not have an alternator (or a generator) anyway.  I do, however, avoid "trickle charging" from the tow vehicle by disconnecting battery using kill switch while towing, a situation perhaps more similar to your marine application.  Could be that's overkill, but at $900 I'm not taking chances.

### ⭐⭐⭐⭐⭐ So far so good
*by J***H on November 24, 2024*

Likes. The amphour capacity of this battery seems to exceed rating. Charging at voltage ie MPPT & charge converter settings keeps battery cool and charges fast. The price of the unit to quality of product is exceptional. This unit is rated up to a 10yr lifespan so time will tell. Keep a eye on this battery because the merchant makes a already amazing price better especially on Black Friday/ Cyber Monday. I will be purchasing two more units to assist in future off-grid solar. The weight of these units are much lighter the. Obsolete flooded lead acid batteries. One draw back is charging at low ambient. Use best judgment mounting inside of RV basements. This space is heated and cooled but it is not recommended to mount inside a coach. Everything is fused in event of BMS failure. Unlikely being a 200a bms.
