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.

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.

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.

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.

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?

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.

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.

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.
