My area sees about 20-30 days per year that get below freezing. On a daily-driven car (meaning its interior is warmed at least once during the day), my interior battery compartment usually does not fall below 32°F overnight unless the outside temps fall below 20°F. For those nights, I have a 12V RV holding tank pad beneath my 100-Ah battery to warm it in the morning. The pad energizes below 37°F and shuts off at 50°F. I've added a 12V timer that starts warming the battery at 5am and shuts off at 9am. The battery is usually above 32°F and ready to charge by the time I get in the car at ~8am. I think my next battery will be 200-Ah. But I also hope to see my current setup last quite a while longer. Thanks for sharing! 73. -Scott, KE4WMF
looks like a really nice battery. love the UL rating . this can be a factor on some fire insurance. the wight is also the 200 amp BMS. they big . great for large inverters . a lot of 200 AH LiFePo4 has only 100 amp BMS. with the cold it is charging in very cold . but charging does add small amounts heat to battery . discharging does as well. from working with LiFewPo4 for some years now in NY . the only ones I seen go bad from low temp is ones left in extrema cold for long time. a battery in use makes a small amount of heat from the BMS. that sealed in battery and warm the cells a tad. the simple fix we use up north in the cold is just insulate the LiFePo4 . their is no H2 gas to worry about. the easiest way to insulate is just use the bord insulation and put all around battery. top and bottom. thin thin insulation from Home depot that is pink and has a pic of pink panther on it works great. it's thin don't take u8p much room and is cheap. I lined my ammo can battery box with it. works great. I can do POTA in the snow . put my battery box in the snow and not worry . low temp protection is great. insulate battery does a hot to prevent this. love to see you do a test on that battery with that tested. use 10 amp load instead of 1 amp. should only take 24 hours instead of days to do test. 73's
Purchased 2 of these to run in series (24v tiny off-grid house) 2 months ago to replace 12 x 6v 105ah Trojan flooded lead acid batteries 24v (4s3p) system which was 4yrs old, so far ... the difference is something I never expected, the lead acids settled at 25.2v at best and the last 2 yrs 25v and dropped to close to 24.4 and lately they settled at 25v and dropped to 24.4 with the fridge turned off at night and careful power usage, these lithiums settle at 26.4 and before the sun shines on the panels in morning they are at 26.1 most of the time, with the DC fridge running 24/7 and no attempt to save power, with a rated 5000 cycles when drawn down much more than it seems I ever will, looks like I'm set for many years to come, plus I won't need to check battery fluid levels weekly or clean the terminals regularly as you do with flooded lead acid.
Batteries are my #1 priority for energy storage and backup power. My #2 priority is having multiple ways to recharge those batteries. For example ~ I could run my entire house for 24 hours (based on my average daily energy consumption) with "Two" 200AH LifePO4 batteries (200AH X 12.8 V = 2560 watts X 2 = 5120 watts). The trick is having multiple and redundant ways to recharge those batteries. 1) Solar panels, Solar Power Station, and a battery charger. 2) Solar Panels, Solar Charge Controller. 3) Multi-fuel Inverter Generator. 4) Alternator from a Vehicle, etc... Personally, I have all of those and a 500-gallon bulk tank of propane that could keep my Ranch powered up to a year, with or without sunlight. 🤠
@@andyirons7162 ~ My only issue with a 200AH battery is the bulky size and weight. I opted for four (4) 100ah LiFepo4 batteries that can be wired in series or parallel, making them much more versatile, lighter, and more portable (if needed).
I put three of these bad boys in our camper with the 3000 W inverter charger and it is a complete game changer for Boondocking anywhere we want pretty much. Very solid batteries
@@takismenexes6131 I have not had any issues with the Renogy Core batteries. On my channel, we do test several different types of batteries . The best battery is the one you don't have any trouble with right? I know some people have had trouble with all different brands so I guess it's the luck of the draw at the end of the day. Ours do need balancing every once in a while, but other than that, they have been flawless
@@takismenexes6131 we test several different brands, the core batteries have been fantastic for us. They are more expensive than similar brands. My first comment must've been deleted.
Had one less than a year Bluetooth failed and trying to get Renogy UK to replace it is an absolute nightmare, I’d never touch Renogy again customer service is worse than useless.
I hear that a lot. and I understand. look at Samsung smart phone caching fire because of battery and a big recall . a SUV burned up from a phone . a girl had one catch fire under her pillow and burned the bed wile she at sleep. she was un hurt . and a kids toy scooter had a battery recall because of fire. that problem was mostly a BMS problem and the type of battery. LiFePo4 is different. and better BMS now. watch HAMRADIO TUBE mike K9MRD took a Chins battery and did a test. anyone afraid of battery go watch that video.
Where does this fear come from? (Serious question. Not being critical of you) This is a safe technology that like anything else, has some bad “manufacturers” producing garbage, or hobbyists doing something they shouldn’t. They don’t “explode” at all and I will go out on a limb and say without researching it, one probably has never “exploded” or suffered catastrophic failure simply b/c a load was applied. I’d recommend @DIY Solar Power with Will Prowse and @Roll2Videos as excellent sources of further education and product review. Do not confuse LiFePo4 with LiOn batteries and the images of smoldering Hoverboards, cellphones, burned down houses and ruined lives etc. These batteries employ a BMS which is literally a “computer” (logic circuit) inside which provides 4+ levels of charge/discharge protection to eliminate hazards to the battery itself and the user. While I personally no longer support Renogy as a company, most everyone I’ve encountered relies on the decent quality of their product. (Some of their charge controllers are RF noisy and not great for radio tho…) “Knowles is key and Fear is both safe and dangerous.” -Me

What's your opinion about batteries since you bought them?
@@takismenexes6131 I have not had any issues with the Renogy Core batteries.

Just got (2) 200 AH Renogy pro self heating smart battery with Bluetooth.
Looking forward building out my power management with redarc at the helm
Nice
Looking forward to your remote generator start.
How does this stand up if two are in series for 24 v systems, do the BMS clash?
I need one to test at Quartzfest!
What do you use to charge your batteries ? Anything different for charging a battery this size ? Thanks. Always appreciated.
Is there any disadvantage to using these batteries with other brands' inverters chargers? I don't like very much Renogy's inverter specs.
No, that should be fine
Had one less than a year Bluetooth failed and trying to get Renogy UK to replace it is an absolute nightmare, I’d never touch Renogy again customer service is worse than useless.
Hmm. I've had mine for 3-4 years, no issues
How long does it take to fully charge this bad boy?
That depends on the size of your charger
im going to be honest. Im scared of these things exploding when attaching to a radio or recharging.
Newer versions of "most" LifePO4 Batteries have improved their internal BMS (Battery-Management-Systems) to reduce or eliminate those risks. 👍
I've never had an issue
@@HamRadio2 ~ I've never had a problem with any of my LifePO4 batteries either, and I own a large and wide variety of them. 🤠

Renogy= over priced products. A case of pay for the name.
My experience has been the opposite.
