That's what I expected. Everybody says do not charge while freezing or you will immediately and permanently destroy the battery but I highly doubt that will happen. You really should try it since you say in almost every review that you should never charge while freezing. It's almost impossible to find a video of anybody that has ever tried it.
-
I too use one of these for my gate opener. I solved the cold charge problem by placing a temperature sensitive "snap" switch in the positive lead from the solar panel. It opens at 35 F. The BMS takes care of high temp and charge control. Crude but effective and the current involved is well below the switch rating.
-
Amazing timing.. I just used that same battery for Halloween.. However, I charge it up use for only 1 night a year, charge it up and let it sit in the garage until next year. Hasn't failed me yet.
-
Will, you are a gift to the solar community.
-
this the reason LFP is currently the best for EVs. Even LFP with Manganese is not good, while it slightly increases density, it sacrifices a lot of the cycle life and maybe durability. I'm also not too keen on sodium ion chemistry for several years as I think LFP will be price competitive considering the performance superiority.
-
Will, you are the battery sensei
-
I had some led acid batteries for 10 years operating in Temps from -7f to 118f and not even fully charged all the time.
-
If time has taught me anything it’s to pay attention to you. So far your information has been solid even in your book. Thanks
-
That’s awesome leaving it out there for two years I know I live in Las Vegas 😂
-
I have Lipo4 300A/ea. batteries for about 10yrs now & still working. My batteries bank about 76K Ahr.
-
Great real-world test! These long-term tests are critical to understand how these batteries last and thus how much value they truly offer. This battery shows that lead-acid is absolutely worthless except for starting ICE engines and even there lithium can be a good value in the long run or in applications where weight matters.
-
Now here's a battery review I want to see....
-
I was guessing 30% loss, Good stuff
-
I always enjoy seeing what's next ! TAKE CARE..
-
Amazing. Kudos to the manufacturer.
-
Nice video! This one of many reasons the Nobel price was given to the inventers.
-
Smiling! Sir Will, yours is a fun channel to watch, I have learned a lot. Been wanting a battery backup for my computers and ham radio since my Alph gell cell died and looks like LiEe Po4 is the way to go. At soon to be 74, seems like they will last as long as me, but I am going for 100. Smile! Ordered the EG4 3000 watt inverter and the EG4 48 volt battery and just got confermation it has shipped. Keep it up sir. 73 K5EDD: celebrating 50 years of Amateur Radio/ham radio this year, great hobby.
-
Thanks for that info. Still a lot of misinformation out there with carryover from lithium ion batteries to keep between 80-20%.
-
FYI, When you order new LifePO4 batteries from the manufacture they are shipped at 50% state of charge by law. So if you don't plan on using your batteries immediately I recommend topping them off with a bat charger to 100% as Will recommends.
