Thanks! Best video on the topic so far

That shut up for a second caught off guard😊

everyone shows the duty charge cycle when a battery needs to be charged up from say 50% capacity. No-one shows what the cycle is when the lithium is fully charged (say from solar during the day) and then the AC to DC charger takes over. Since the battery is full shouldn't the charger go straight to float cycle?
What would be superb is if someone demonstrates with a current and voltage monitor how this varies depending on the SOC of the lithium battery.

People say Lithium batteries don't do well in cold temperatures. I wanted to ask if this also will make it harder for them to charge up in cold weather since they already don't do as well in it?

Thanks for any input on this.

Should I keep Litihium batteries plugged after they are full?

I use a Li-ion battery for my camera. Bought a new battery recently and it seems like its life is less. They are supposed to go for about 1 1/2 hours. This one goes about 1 hour or less. I'm confused.

Australia has nearly all the worlds lithium. Africa has small reserves..
The problem with lithium ion phosphate batteries is that with time they become inherently dangerous, its not just the unstable chemistry its the seperator, more expensive is better with these types. Another problem is the fact that lithium ion batteries cannot be rapidly charged, this is exactly why you dont charge them using car alternators not wven with a 100 amp BMS most are 50 amp BMS

I know this is fairly old video but i have a question i cannot seem to find the answer too. When a lifepo battery is fully charged the current will drop, if a charger were to remain on at a constant say 14.4 volts, would it damage the battery or once the battery is fully charged would it act like a hose with water and a faucet and just stop accepting any more charge even though the faucet maintaining the 14.4 volts but low to zero current? I know a bms will stop over charging but im asking if there were no bms how the lifepo battery itself would react. I ask to understand how dc to dc chargers and solar charge controllers work when the sun charges the battery/batteries daily or most days. If the battery is full then what does the charge controller do with the incoming electricity, turn it off like a faucet once it realizes the battery is full? Im trying to understand independent of a bms if chargers are sensing state of charge and stop trying to charge a battery.

I have a Z6 ninja electric with a lithium batt. When I get a full charge it reads 82 instead of 100. Why is that?

[ukestudio]

Should you let lithium battery run down to zero .? Before recharging ?

I have a couple of cyclical Solar Panel lead acid chargers which were designed using discrete components some time ago but never used. The charge current via relay operation connect the solar panels direct to the lead acid batteries and disconnect at the recommended 14, 6v cyclical level for Lead acid. They reconnect when about 25% DOD is reached, in order to maintain an acceptable level of charge for an intermittent load. They assume that the Solar Panels max current on full sunlight is within the suitable charge current for the battery. Would they be suitable for Lithium ion batteries if I was to adjust the reconnect voltage to the higher value required for a lithium ion battery's let us say 25% DOD. There is no trickle charge which could damage the Lithium iron battery, which supposedly would limit the battery life. The reset switching level could be reset to the recommended "Topping charge level". Would my old cyclical chargers then be suitable for Lithium iron battery's

Alright you might actually be able to answer my question related to lithium ion batteries
These things are weird and I have no idea how to deal with them
Every video online is either about iphone or meant for people who are cool with replacing em every 2 yrs

Currently I do 5-80 15-80 20-80 or 40-80
(stock rom was driving me nuts bcs I didn't want to bother looking and timing it and I knew charging to 80 was way faster than 100 so I got a custom rom and got a charging limit)
Now ik temperature and battery cycles are a thing it's just 20-80 30-50 isn't Alot and my 10 watt charger doesn't charge it fast enough to be worth it and I'm broke.

I have an asus zenfone max pro m1 4gb with an sd636 soc, 4gb of ram and a 5000 mah battery
It was a hand me down I got February of 2021( it had around 3700mah when I used accubattery in 2021)

Now the problem with replacing batteries in India is that you have no idea of it's fake or if it's too expensive by the time it becomes a problem and getting original batteries will be impossible unless it's in the 1st 3 yrs of the phone's release where getting parts are easier


My experience with a htc one m8 my previous phone which I had for 2 yrs running android 8 custom rom
It was also a hand me down from a friend battery was terrible
It heats upto 70-90 degrees underclocked it to keep it below 60
Takes 4-6 hours to fully charge 2600mah
It would die after it reaches 20 percent and it was a 3rd party battery I got when I received the phone


So from my experience constant 0-100 does not reduce the capacity by much but it pretty much kills your battery at some point or it just charges slowly and dies when it reaches like 20-30
So now I want to know what I should do
With the custom rom my battery capacity estimate is around 4000 and on a long day I charge it to a 100 a few times rest of the time just 80 and I never let it die other than the rare occasions where I forget to charge
It maintained 4000 mah

I want to know of it's alright to charge from 5 or 10 percent since I know above 80 is bad bcs only being able to use 60 percent is too difficult

[livingthelava]

No, sorry, that was terribly unclear. Maybe be more linnier and use exact numbers.

Hey. I think that when you posted this video, you accidentally set the wrong language in the video's YouTube settings. Since you're speaking in the audio track of the video, YouTube will try to create an automatic translation for me into a language I understand. Since you're speaking in English, but you've accidentally told YouTube's publishing system that your language is Dutch - the end result is quite confusing right from the beginning of the video:

Your literary will look like this:
"lithium batteries and van ladders similarities to major der de structuur functionality compared to the two additional la place patty's day goose left to day van de lekt rood benadeel elektrische mee doet dit formaat euro speakers woon dus meters om kleine lithium en de ck one is made some kleine we carbon base material and the select roze roze place de sangha electro light met na mijn set of these works at the led light consist of salts motor time de zo hoofd in organic solvents een ander die aan de stijn worden first word in libië microscope van pica's wonen die lecteur this made of lithium and no one to explain worden sec"

So you can see for yourself that this result doesn't make any sense because google translate THINKS you're speaking Dutch even though you're speaking English!

I'm sure you can find a section in your video settings to change the language to English. Thank you in advance :)
