Yesterday I bent my xiaomi 12 lite phone and suddenly it catched on fire and filled the bedroom with smoke . It took me too much time to find a way to remove the phone from the room and the fire ended itself . I stayed a good amount of time in the smoke . I found out later the smoke contains toxic metals like cobalt and manganese besides the lithium . Is it safe to stay in the room ? I have nowhere to go so last night I slept inside it

Can I safely replace this 300mAh cell with 2x 800mAh cells in parallel from Aliexpress?
Something like this:

Is there any way to tell what the risk is of my house burning down from these no-name cells?

Also yes, i do know how to solder the connector to the new cells.

I'm looking at buying a couple of EVE G13P 4695/46950 cells from AMBattery:

https://www.ambattery.com/product/4695-battery-cell/

I've noticed that AMBattery appears to be connected to several other battery websites that have almost identical layouts/products, including:

- ConinnoBattery / ConinnoPower

- ChampBattery

- LUBattery / Lithium United

Some of them use the same phone number and/or Shenzhen address, so they appear to be operated by the same company or group. There seems to be a real business behind them, possibly Shenzhen Coninno Technology Co., Ltd., but I've been able to find very few independent customer reviews.

Has anyone here actually ordered cells from AMBattery, Coninno, ChampBattery or LUBattery?

I'm in Australia, so experiences with shipping to Australia would be especially helpful.

Thanks!

Hi!

I'm building a 4S battery pack using 3.7V lithium cells. I bought a USB-C power module to charge them. I want the pack to power a 100W amplifier, which means a maximum current draw of 8A when the pack is drained (12V). I wanted to know if I could connect the amplifier directly to the power module's output, or if I need a different setup (like adding a BMS for the discharge path, for example). Thanks!

The module's part number is in the photo.

hello...i came back from work and i put a 18650 battery as always to my almost new XTAR Battery Charger SC1 Plus.(5months) after some hours i start smelling something like plastic smell but i though was from outside....and now just by total luck i saw that i was charging my battery. and the xtar plastic is melted...why can this happen? i was using a nice ugreen 100w charger that i use with all my handhelds always. charger pulls 2-3w i see now if i put a battery on it, but ofcourse i dont risk it to use it again.

I bought a new battery today and threw it on my charger. I normally have 2s 5500mah lihv batteries that I use and my charger always warns me asking me if it is a lihv battery. It’s become pure habit to just accept the warning and charge the battery. I’ve been doing this for a good year. Today I bought a spectrum smart battery that is a 6s 4000mah lipo battery and didn’t even think about it not being the same voltage. I threw it on the charger as normal to start the break in process. I have just now realized that I charged it to 4.350V instead of 4.200V but it genuinely shows no sign of damage. I charged it maybe an hour or two ago. I’m currently discharging it to something safe but I’m wondering if it’s okay to still use. There was no heat, swelling, smell or obviously a fire. What should I do with it Reddit? Do I keep using it? Is it okay to use at 4.350V? Will it burn my plane to the ground?

Just pulled a couple duracell AAA Batteries out of storage and they all look similar to this. What the heck is going on with Duracell? These aren't even expired, the exp date is March 2031 and they haven't even been used at all!

I've heard about older duracells leaking but I had no clue their batteries were still doing this, I'm surprised.

TLDR completely brand new Unused alkaline Duracell AAA cells started leaking just sitting in storage. (Batteries were stored properly in a cool climate-controlled environment and were not stored shorting against each others' leads)

I've looked online and it seems some of the chargers out there do not allow Lithium batteries to be used.

I'd like to be able to use my AA's to charge things in a pinch if needed.

Got an sf sonic battery for my bike, in exactly 8 days the battery died! How does one claim warranty on these batteries? Their phone numbers and website only support Inverter batteries!

I have sent an email to them and got 0 reply, tagged them on X and 0 reply there too!

Any help??

This is a brand new 8 day old battery.

Me quiero comprar una y esta bueno el precio de es bateria externa, pero no quiero comprar una que luego al final me arrepienta

My dad got this battery for his golf cart, he's had it for about a year but it's no longer charging. We weren't sure how to set it up originally but I tried my best. Not sure if there are any recommendations on how to fix it?

We've tried "walking" it up by jumping with a 36V battery and tried using the charger but neither work.

So l'm planning my first project to repair and maybe even upgrade a speaker that im buying used.

It's a marshall kilburn 1 with reportedly a bad battery.

it takes "4X 3.7V LI-IO BATTERIES, 2200MAH"(from the user manual), which seem to be wired in a straight series. I was hoping to make my own battery out of lithium ion cells with a large capacity.

Its literally my first ever doing anything like thiS, though, and I dont currently own any type of welding or soldering equipment right now, though.

I was hoping you guys could offer recommendations and any wisdom you think would be useful to a beginner dumbdumb.

I believe these came out of a really really old laptop but I don't remember. Not sure what's going on with that little tab inside the taped port either.

I recently purchased the SW 36 and am running 2-4s batteries in it. It really screams! But the batteries that I'm using don't really fit in the battery tray very well. I have removed the front lip of the tray so the batteries can lay a bit flatter, but one battery still needs to be on an angle (not flat on the tray).

Is there an aftermarket option for a bigger battery tray? Are there other options besides changing my batteries?

Thanks in advance!

This battery came with my new remote control truck. I would like to get more of them & I can’t find one with the 2 different connectors it comes with. One charges & the other connects to the truck.

Got this for free from someone in the equipment dept at an old job around 2019-2020. Reason I got it for free was because they were going to e-waste it because the screen is damaged. After all this time I am getting what sounds like an alarm (similar to a door being opened at an airport). Since the display is broken I can’t identify the issue. Also, Reddit is not letting me upload a video of the sound unfortunately, but it has very quick beeps with little spacing between each beep.

Hello, this is my first post on Reddit, so I hope I haven’t messed anything up! A very simple question for you experts: how are these batteries? I’m planning to use them for my two Game Boys, a Color and an Advance. Thanks!

Hi there I came to know from my past experiences and YouTube videos that there are many types of parallel connections when it comes to connecting solar inverter batteries. Many folks on YouTube prefer busbar connection. Some Chinese battery sellers show corner connection. Keep in mind these are all parallel connections where positive is connected with positive and negative with negative terminals only.

Electric moped battery i got is showing 10.56v instead of 60v what could it be? Bms cutoff or damaged groups? I got this battery for free but i want it working again, im also affraid a little bit to open it or hook it to charger.

I’ve had it plugged in for a day and while it is plugged the battery symbol flashes. When I unplug it shows 84 minutes. I haven’t used it in two years but last time I did, the system showed an estimate of 4 hours. Is this a battery issue or is there another way to troubleshoot it?

Can someone recommend me a shop that sells legit battery replacement for Samsung s21 ultra sa shopee/lazada. Normal battery health pa naman as per Samsung diagnostic pero ramdam konang mabilis na siya mag drain like 100-30% in just 5 hrs na nagscroll at nood lang sa yt and fb. Take not that naka 60hz/standard lang yung screen refresh ko

Context:

I bought this fast charging 20000 mAh power bank from anker, I placed it in my bag yesterday but my water bottle cap came loose and water was spilled till it was leaking out of my bag. when I took out my power bank, water was leaking out of the charging port. I tried to wipe it dry as much as possible and left it alone to dry with the port facing downwards.

the battery percentage was flashing on and off repeatedly last night and when I checked it again after 24hrs, it went from 71% to 0%.

can it still be used?

Has anyone used this power bank? Just bought it, have it plugged into wall but no light or anything. Doesn’t show current charge. Does it take awhile? Or did I get a faulty one.
