Hello, feflo . how many hours can this last with a mini lenovo laptop and one phone?

The package is without battery. It's battery that determines duration. If used with 2pcs 100ah batteries, it should last for about 10hrs with your stated load.

Thanks

I can finally comment after taking it through its paces, thank you @feflo for your honesty and patience with my plenty questions and clarification even at odd hours. Only use it wit my LED tv and dstv decoder and even after abt 5hrs of use, battery is still at 55%. Keep up the good work Chief

Many thanks for your kind words, like I always say, I'll be with you all the way.

lithium ion cell are very good. Just like I discovered common 48ah lithium ion battery performs better than 100ah lead acid battery. Lithium ion technology is dope.

It's a pleasant surprise to me too. Many thanks

Interesting, the low resistance trait of lithium makes charging it faster than our conventional lead acid batteries. I think bottom balancing the two lithium pack may help with the voltage difference

Many thanks sir, will work to balance them and then continue with the test. I so much appreciate your input. Thanks

Day 1 TEST CONCLUSION

My 48vdc 60amps lithium pack performed far better than my 48vdc 185ah lead acid pack.
This test is ongoing and will update as soon as time permits.

Observation

I noticed that one pack performed better than the other pack. There was a voltage difference of about 2v between the packs. At a point one was reading 27v while the other 25v. I'll work on correcting this.

I also noticed that the lithium charges faster when compared to Gel or Lead acid batteries.

I immediately put on my 750watt pumping machine and it worked for an hour, used an electric Iron(1kw) for about 30mins. Used it overnight on three fans and other light load. I woke up around after 5am and the battery was 52.4volts. Pumped water again for about 15mins and the voltage was about 50.9v before leaving home this morning.

UPDATE ON LITHIUM TEST

I was able to finally put my lithium to test
It was hooked to my 2.8kw solar array, I adjusted the bulk charge voltage to 60v and the float voltage to 58.8v (each cell has voltage of 4.2v and one battery pack has 7 cells making about 29.4v per pack).
I connected the two packs in series to get 48vdc. I got back home at around after 4pm and it was already on float.

Just like you suspected, the BMS may probably be incorporated into the control board. This is awesome, I'm on the lookout for a not-so-expensive lithium setup these days. So update the house on how it goes. Thank you.

I definitely will. Many thanks

Yeah, the PCB holds the BMS for the cells. Those MOSFETS are BMS components.

Thanks sir.

Can you safely do that? Do you know the maximum charging current that it can take? These guys hate to be abused. Lol.

I guess I know what's safe for them and my charge controller can be easily adjusted to safely handle lithium. The technology is still relatively new that's the reason I keep researching about them.

Many thanks for your concern.

Interesting, how much is it and what's the run hour on say 100watt load?

I plan to hook them up with my solar system at home and use for about a week before knowing how efficient they are.

Did you see a BMS?
Was any of the cells bad?
What's the capacity of the lithium battery?

It comes with a motherboard (pix attached), I suspect the BMS is incorporated into this board.
All the cells are good, if not for the fact that I've been a little busy I would have been done with the testing.

Thanks

I finally had to bypass the UPS socket and connect an extension directly to the output cables in the UPS and it's working now.

Good

Technology Market › Re: World's Smallest Power Inverter by feflo(op): 7:35am On Jun 12, 2019

feflo:
There's no way it will not work if properly done and the components are all working correctly. This is same way I get output from all my converted APC UPS and I've not experienced a single issue.
Firstly, check that your UPS has output.
Then check the cable used and the socket, one of the listed is faulty.

Thanks
