Redodo "Low Temp" Battery Review. It still charged after low temp test...

- Redodo has never given false claims about their products, but this one didn't work the way I way expecting. I put it in a deep freezer for 24 hours and it still tried to charge. I've watched other reviews where they took the battery apart and tested the sensor. It does work, but could it possibly have a problem with the way the sensor is mounted inside the battery?

This is the big problem with the manufacturers claiming LTP but not necessarily having the settings correct. Your video is the standard for testing this at the proper temperature. Having LTP set at 10F or what below 32F is not protecting anything. Great job pointing this out
Thanks. I did the test a second time and it worked like it should. I still don't trust it 100%. Thanks for the comment.
JUST bought that battery..haven't even taken her outta the box yet..lookin' forward to what you found about it.👍
I did another test on the low temp charging and this time it worked! Overall a good battery IMO. Thanks for the comment.
Thank you for the Redodeo review!
Any time! Thanks for the comment!
24 hours was not long enough. After a day of charging and discharging the cells, we're probably close to 40°C or 104°F maybe even hotter. The cells have a lot of mass and material to cool down. Myself and Brad both tested the temperature prob directly with different results.
I did the test with two other batteries in the same fashion and the cold temp sensor worked just fine in the test. I did the test again and it didn't charge, so that's good. I'll start leaving the battery in there for 48 hours to make sure. Thanks for the comment!
@@OffGridBasement Thank you for the video.
Red-odo = "Red-oh-dee-oh", lol..just pokin' your ribs bro 😉😂
Excellent review brother.. I specifically bought this version of their battery for this very reason.. and after seeing so many fail, I'm always worried that the temp sensor isn't going to work.
So I'm bummed..this is like the 10th battery of various brands that I've seen the BMS improperly programmed to where they're either not cutting off the charge until it's in at least the high 20's, or not at all..
I've made boxes for my batteries that will never allow for this low of temps just as a precaution..but dangit I shouldn't have to.
Plus I need to find ones' I can count on for our bugout location where low teens are common.
I'm not Will Prowse so I won't likely be re-programming a BMS, so I guess the search continues..very disappointing. Plus the non-low temp one was $50 less 🤨
Yes..this is getting old. Why they aren't testing these before they leave the plant is beyond me.
How I long for yester-year.🙁
I did the low temp test again and that time it worked! Hope it was just a fluke. Thanks for the comment.
@@OffGridBasement Oh man.. thank you brother..seriously, I was bummin' big time.
Thanks for bein' a thorough content provider. I'm seriously relieved 🙏👍
@@OffGridBasement Yes, I echo Nat...I was also bummed. I was thinking I could have just saved 50ish bucks per battery if they're not going to work to shut the charge off anyway? Thanks for telling us I feel much better! Good on ya buddy!😉
Vatrer got an ‘affirmative’ on LTP.
At the end of the day, NOTHING that is Chinese produced should be expected to have consistent QC. I think that even the more ‘common’ / high volume labels will have Noteworthy QC issues.
I was hoping you'd pop the top off.
Redodo, formerly Zooms, is actually made by Enjoybot. They also make Chins, Ampere Time, and probably more. I believe the Chins literature or box says made by Enjoybot.
Anyhow the Chins started out with prismatic celles and then they switched to pouch cells. So I was curious if the Redodo was also now pouch cells. I have 4 Zooms, 8 Chins, and 4 Ampere Time. They're all still working fine after 2 years. It's ridiculous how cheap they've gotten. You can buy 4 Chins for $769. plus tax delivered. But it all depends on whether they went back to prismatic cells or not in my opinion to make it a good deal.
Thanks for the comment and info.
I believe I read somewhere you can charge these batteries at lower temperatures but it must be done much slower. It looked like the charger was only charging at 3 amps, or was that just the charging rate maxed out on the charger? This is speculation only.
Yes, you are correct. Some LFP cells can be charged at significantly lower temperatures (down to -20C/+5F), but most cannot. But yes, all LFP cells can be charged very slowly at lower temperatures. It is possible that the BMS was smart enough to allow it but somehow I doubt that was the case in this instance. I would say the more likely scenario is that the BMS was mis-programmed.
The charger was set to 3 amps because I didn't want to damage the battery if it did start charging. I believe the BMS should completely shut off if the sensor is triggered. I did the test again and it worked like it should. Weird. Thanks for the comment.
Their website has some that are low temp protected, and others that are self heated. I wonder if yours is self heated, or maybe the BMS settings are set wrong so it *thinks* it's heated.
I did the test again and this time it worked. Still not convinced it would work consistently. I'm glad it triggered on the second test though. Thanks for the comment.
The 12.9V is definitely not a feature. That probably means the BMS's charge and discharge FETs were both turned off as part of an over-voltage protection circuit (both before and after you attempted to charge it), and the voltage was due to leakage current going through the turned-off FETs or held by a capacitor on the output. Probably leakage. Which is another way of saying that they took some design short-cuts. Not sure what reactivated the battery through, but it really feels like something funky happened.
I was amused by the pronunciation of Redodo. "Rey/Ree" - "Doh" - "Doh", as in Do-Re-Mi-Fa-So-La-Ti...

Thanks for the info Matt. Much appreciated.
