What I didn't see you test was running the UPS near max capacity. I think the BMS on the Dakota cells limits the max discharge rate to 10a. So it's likely your 1500va (1000w) ups will shut down if it sees more than about 360w of draw. I did this to one of my UPSs hoping to keep from replacing batteries every three years. It only worked for light loads. I had to go with an external battery pack that allowed higher discharge rates. Still, a good video to inform us of alternate battery types.
Yeah, to be honest I didn't really look that deeply into it but I just wanted something that would be a good replacement that wasn't SLA. I was pleasantly surprised when I found this out.
The OPTI-UPS Durable Series DS1500B is 1,500 va (volt-amps,) and 1,050 watts max draw. It's been four months, how are the lithium batteries holding up? Is the runtime better?
Opd hahahaha The batteries are doing great! The runtime seems to be the same since the charging system is not set for lithium but for lead acid. So technically the batteries are getting charged not to full capacity at like 12:13 volts instead of 14.7
Prob don't want them to be held higher than 13.5v. I was thinking of using LFPs in my ups but it floats at 13.8v so I'll just replace with cheap SLAs when needed.
Yeah, they don’t charge them as high because it’s still using the SLA chemistry for the charging rhythm/curve. So technically they’re not being charged up all the way or they’re supposed to be.
@@TekShinji I know that holding a 12v (4S) lifepo4 battery at 13.43v will keep it at ~92.5% state of charge, so holding at 13.8v would be (as good as) full.
Sus isn't it? Haha because I was being sarcastic... I've only changed the battery once on that particular unit but other ones many times. Usually I run them at full load. 24/7
Hello I wish I will have seen your videos I have been changing out SLA for 12/14AH batteries on all my ups to 18650 that I build myself and I run my solar system to one ups that’s 1500 watts and then that one runs to another that’s 1000 watts and the a 750 and stops their ! But I have been dining this for about 7-8 years now and this system has not left me in the dark ! Nice to see someone making a video on how easy it is to change out ! Even thou Apex does not approve of this !
Yeah they don't approve of it. And technically they say it's not the way it should be unless it's a lithium-based charger too. However, it seems to be working great and honestly it seems to be better at holding a long load for a longer period of time versus the SLA batteries
So my 12 v ups uses a 12v 5ah sla. Can I just put a lipo 12v 5ah battery in it? So if I understand the lipo has higher operating voltage and charging but the UPS device is wired for sla. So you think I should go with 12v 6ah lipo?
Hey there, it’s highly dependent on how the UPS is charging circuits and stuff are designed. For a really really old UPS I try to stick with like for like. However, as a general rule of thumb, I try to go with as much capacity with with the same voltage and physical space as possible.
They are lithium Iron batteries so much more safe as well. The info is in the description! Let me know if ya want to know more! Or dm me in tekshinji discord! ❤️
I found this video of much interest. I will tell all my closet people how much interest of this video so they to may share my interest of such video topic. I wish deeply many more videos of such interest in most interest of my future.
have you ever used a Lithium battery in your UPS? let me know!
yes! and I 3d printed a new case for it :)
Very nice! I need to see that!
I need more lithium batteries In my life 2kw isn't enough
I think 50 kw is adequate
@@TekShinji if I could afford it I need 200kw..lol
I did the same thing to one of my ups's, works great. Nice more relaxed flow of your video as well.
Thanks buddy! Glad you enjoyed the new edit yeah, I think these lithium batters will last a long time

Hey there, I actually was able to run it at the 1000 w capacity. Didn't have any issues.
@@TekShinji Cool. Those Dakota cells must be better at higher currents than some of the no-name ones I've tried in my UPSs. Good to know.
Yeah, to be honest I didn't really look that deeply into it but I just wanted something that would be a good replacement that wasn't SLA. I was pleasantly surprised when I found this out.
So its have been 2 years, did you have any problem with the lithium battery? Any update on this UPS?
No issues whatsoever it’s been in useful time 24 seven since I’ve made that video!

I still don't grasp the premise of why you're replacing batteries so often... and why if that was the issue didn't you know how where the screws are?

LOL great vid Shinji. Hey are those Lithium Ion or which Lithium batteries are they (there is a few)
They are lithium Iron batteries so much more safe as well. The info is in the description! Let me know if ya want to know more! Or dm me in tekshinji discord! ❤️
Battery back ups the Bain of TekShinji Existence LOL. I have to do this every 2 years times like 12 units cry
Hahahah yes the SLA was about once every 2-3 years. And the others were about once (adledfely) 6-10 years
Occasionally, I use Lithium Batteries in my Xbox controller 😎
They definitely lost a lot longer. And in something like that I guess every ounce counts!
I found this video of much interest. I will tell all my closet people how much interest of this video so they to may share my interest of such video topic. I wish deeply many more videos of such interest in most interest of my future.
Hahaha Nice comment, I hope there's more to come!
15th try is the charm ninja chop !
Hahaha yeah can I get that Jack chop
Oh fudge!! Hahah
Tasty! Tasty delicious fudge... 😱
The "Oh fudge" edits had be dying!
Fudge is delicious... Christmas story it is...
I neeed🤘🤘🔥🔥
Hahah I don't regret it. It's been in there for a couple months and it's great.
@@TekShinji great vid was really funny too🤘🤘
I'm glad you liked it! Gagga
5:50 lol.... this guy
Ahhaha yea I like fudge ..
Hilarious! Lol
I totally know what I'm doing 😄😄😄
@@TekShinji I'd be fumbling through it as well. You just had a camera there! lol
i enjoyed this but the cut's and question marks where stressin me out lul
Lol, yeah it was supposed to be funny but I know it makes some people stress out lol
Was both for me laughing whole time but stressing lol
I forgot what I was meant to do in the comment section xD
Hahaha I hope it was because you were laughing!
