@@JOHNDANIEL1 Ah, didn't know about the lifespan. Thanks
I was so impressed with the REDODO 100AH battery, and the support, that I purchased another one!
I was soooo hoping for prismatic cells. 😊
I have one of those sweet batteries, was wondering what was inside, but didn't want to take mine apart to find out; I'm glad you did. I had a feeling there were pouch cells inside, I couldn't imagine how 4 prismatic cells could be arranged in such a way as to get a battery of that size.
I’m starting to think the redodo, litime, and power queen minis are made at the same place and they’re just tricking us with the colors 😂
I'm going to say incredibly likely. Not just the mini's. I think there is one, or just a few actual manufacturers. These companies seem to just slap their name on it.
@@BradCagle Yeah very common is most industries nowadays, just a color and sticker change. Purchase would likely lean towards which sticker is gonna be around the longest for warranty purposes.
Great Job on the review!
Thank you sir!
Nice! I just received my two 100ah mini's from LiTime yesterday. I'm currently running capacity tests now.. hopefully they're just as good as these. Should be, they're pretty similar. Thanks so much for the tear down!
Do yours have the strap attached to the top of the case too?
@@BenMitro Yes a black strap.
@@hiddentomato Thanks for replying. Cheers!
How did the capacity tests work out for you? Also, did you notice the BMS cutting out charging even with 14.4V charging and 2A tail current?
@@ormandj Pretty much same as the Redodo, one got 105Ah and the other 106Ah. It was performed using a DL24P tester with 12A constant current.
Great review and well done Redodo, seems like a little firecracker of a unit.
Thanks!
That build quality and design looks very good. Keeping pouch cells under slight, evenly distributed compression is vital for longevity
Yes, I think they did a good job! Thanks
Redodo should have a battery out during the first part of July/24 with a bluetooth option. I've been pushing for a long time for this option. I hope it's offered on the mini!
I actually asked the company why a larger case and was told if we made a small mold you would be paying more for the battery
About time with the smaller case!
It looks like they can easily create a 48V/25AH variant - smart!
Price is ok too. Nice review Brad.
I was expecting you placed each battery on bathroom scales to see the weight difference between the standard size and the smaller one. (I expect that to be negligible).
Yes, I was thinking the same, would make a sweet little 48v 25ah, I was even thinking how I could unweld the tabs without destroying them LOL. I should have totally weighed them, dangit! Thanks for the comment!
@@BradCagle Always look forward to your videos Brad. Informative, to the point and not too chatty to fill in the time - some channels that do that bore me senseless and I am constantly skipping ahead. With your videos, none of that is necessary. Keep it up. I hope your channel grows substantially - it deserves to.
@@BenMitro Thanks a lot! I'm constantly trying to improve :)
@@BradCagle Don't improve anything! Your presentation is perfect for me. :) I hope others I send your videos to will agree.
Any drawbacks of the mini compared to the regular sized Redodo 12v 100Ah LiFePO4 battery? Excellent reviews as always by the way! Thank you!
Not that I know of. Thanks!
it's better to get regular size of Redodo they are prismatic cells.
Wow, the choice of batteries in the USA,
you get so many to pick from compared to what we get here in the UK
This is what I hear often. Wonder why they don't serve the UK market so well? I'll ask these guy's what's up with that.
..or the Australian market.
Anyone know how ‘pouch’ cells compare to Prismatic cells ?
And the only insulator between the cells and the BMS PCB is some tape? How long will that last in a RV bouncing down the road.
There's a pretty good air gap between the tops of the cells, and the bms.
What do you think customer support would be like with this brand?
I'm not sure. Probably similar to other like brands in this price point.
What is the maximum capacity and size battery bank wired in both parallel and series to a 120v inverter? I understand you can wire 4 in parallel and 4 in series. Does that mean I can wire 4 sets of 4 in series, then wire those 4 sets in parallel for a total battery bank of 16 batteries at 48v and 1600 Ah or 76,800 Wh ?
Yes 16 total like you said. But your total power calculation is off. It would be 48v 400Ah = 19,200Wh ( Well it's actually 51.2v nominal so 51.2v * 400Ah = 20,400Wh)
Thank you very much, and for correcting my calculation. I wonder why you are limited to 4 in parallel and 4 in series, does it have something to do with the BMS ?
@@DavidHaney1 Yes. It's a limitation of the BMS in series because the mosfets can only handle so much voltage. As for parallel I'm not sure, seems like there is nothing limiting that.
Hi, I've just ordered the same battery. I can't find any information about the charging voltage of this battery... Is a 40A booster charger (MPPT CB12-40 Energie Mobile) compatible with this battery?
(I've heard that a lithium battery accepts a charge voltage of 100A...).
Thank you
I'm not familiar with that charger. But usually the charge voltage used is between 14.2v and 14.6v
👍👍👍
Nothing wrong with pouch cells... As it's the BMS that matters..
Unless you want to go poking holes in the cells..
Agree, I think they are fine too.
Which one is better litime or redodo?
They seem to me the same.
I don't like how pinched the power leads look.
Can pouch cells be more dangerous?
Well they are more fragile, however the case, and fixture in this battery Is much beefier than others. So I think that was designed to keep them safe. I'm not sure of other dangers of pouch cells, I need to research this. Thanks
@@BradCagle Do you think laying it on its longer side would cause the pouch cells to dislodge and jam into that long bolt holding it all together?
@@hiddentomato That's a good question. I wonder if it would in a high vibration environment over time, like a van/rv?
@@BradCagle That's my worry as I was going to install it in that orientation in my honda odyssey mini van camper I'm building.. hmm.. :\
I did see that there are 2 pieces of foam on each side also, do they sit firmly against the pouch cells or do they have some play in there?
A lot of companies are switching to cheaper pouch cells💀
not a m22nf replacement
Is that a sealed lead acid battery you're talking about?
👍👌❤️🇨🇦
Red Doo-Doo sounds better
:)
I wish companies would disclose if they’re using pouch vs prismatic cells. Pouch cells are notorious to have violent thermal runoff issues - as they do not have a venting mechanism and mechanically are more prone to damage. I would not buy a pouch cell based battery (or car). I like the form factor and overall design but it’s a big 👎 for me
I haven't heard of much thermal runaway problems for LiFePO4 chemistry, I need to look into this for pouch LiFePO4. As for more prone to damage, true but this design seems to have taken that into consideration, it has a much more rigid, and form fitting case, plus the compression fixture. Thanks for the comment.
Agreed ! But they’re cheap and that is synonymous with Chinese tech . That and their business ethics will be their downfall
@@robertdillon9989 Actually, pouch cells are more of a Korean thing. Chinese mostly do prismatic which is a better design. As for cheap - that's what people are looking for and unfortunately, it's pushing manufacturers to use problematic technologies. Unfortunately, I expect car makers to move away from pouch cells which will generate a surplus of pouch cells for retail market - so we should expect to see a LOT of these type of batteries.
@@BradCagle LiFePo4 is less prone to thermal runaway but when you store so much energy in such a small space, something has got to give. Also, most LFP are sold as prismatic cells which have much better handling of thermal runaways, thus less fires, and less headlines.
I've been using LifePo4 pouch cells for my quadcopters for many years, I've never had any issues with them thermally.
