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

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

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

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. 🤠

Looking forward to your remote generator start.

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.

How long does it take to fully charge this bad boy?

im going to be honest. Im scared of these things exploding when attaching to a radio or recharging.

Renogy= over priced products. A case of pay for the name.
