Also noticed the VATRER 12V 460Ah LiFePo4 batteries are in a metal case, don't think this would be good in a salt air marine situation, would stay dry but metal would not last unless its aluminum.

I'm having simmuilar issue with my Renogy MPPT charger and there tech help has been no help they just reads everything out of the instructions manual which I have done no help, I'm done with Renogy and will not purchase any of there products.

Does anyone here have any info on the VATRER 12V 460Ah LiFePO4 found them on amazon for $1200 each, seriously thinking of getting 3 of them for my 12V boat. Was looking at 4 JITA 12V 300Ah Lithium Battery LiFePO4 @ $800 each for a total of 1200 Ah but with 3 X 460Ah this would give me 1380 Ah...

Would be on my Catamaran in the tropics so low temp cutoff not an issue for me. Would be for anyone in cold climates

Just notices it does say it has Low/high temp Cut off. But need to do more research.

Yes was looking at getting 4 in the next few weeks which would give me 1200Ah, but just found these VATRER 12V 460Ah LiFePo4 batteries with a 250A BMS for $1200. Need to do a little more research thinking of purchasing 3 which would give me 1380 Ah. Will also start a new thread here on these...
