Hello, I'm currently building an outdoor project with an ESP32 and a few sensors. I'm using small 5V solar panels for this (as planned) and would like to build a buffer out of LiFePO4 batteries because they are cycle-resistant and temperature-resistant; they are generally very safe. The only problem is that I can't find a…
Good afternoon dear people I got a 7.5 amp battery for a good price. However, I charged it, and when it was fully charged, I measured 38V. So I thought, hmm… surely one of the cell blocks must be defective? Since one spot got quite warm while charging, 30-40 degrees, it's not that much, but…
Hello, I'm looking for these mud pants in size 152. The color doesn't matter. Where can I buy them? They're sold out everywhere.
How much load does a 48 volt li-ion battery need for the bms to output power
Hello, in Austria, a commercial school is equivalent to an apprenticeship (office clerk). Does this also apply in Germany? Best regards
I plan to use a gel battery as a power bank and have already done some research to find a suitable solution. First, I'll install a fuse in front of the 12V gel battery (the exact specifications have yet to be determined). Next, I plan to integrate two of these voltage converters ( https://amzn.eu/d/f8uvJg5 )…
Is there any way I can operate my keyboard without a BMS? Soldering a new chip on it won't work because one of the circuit paths is broken, and the BMS chip is only for the battery, right?
For a Bluetooth speaker project, I need a battery that delivers approximately 12-18V. For this, I would connect four 18650 cells in series. Now I'm wondering how best to charge them, as this is a tricky topic. I know that I need a BMS for four cells, but I'm not entirely sure how to charge…
I've had a Xiaomi 1S in my basement for quite some time. At some point he went out in the rain and has been acting completely crazy ever since. Now I had bought a new 3 Series as a replacement, but it was stolen in the first week. My guess is that the battery's BMS…
I build a battery box with 18650 batteries With an output voltage of 25.2V, that's 7 cells in series. I would use 8 cells per row. So, each cell will have 8×18650 batteries. Of course, I also need a BMS for this. The maximum output current is 13A. Should I look for a BMS for…
Hi, I want to operate a device with just one battery cell that also needs to be recharged. Do I need to install a BMS (and how would that work, since there are only two available ports on a cell)? Greetings
What is the yellow cable on the BMS for? I've never worked with batteries before and don't want to take any risks. Can someone explain to me what the cable is for, what the BMS does exactly, and what I need to pay attention to? The yellow cable is marked with t next to the…
