MOSFET BOJ70N62.
Did you test them off the board? What is the resistance are you seeing, <1 Ohm?Never stop learning

Hello,
it's not a laptop/desktop related question but I figured that someone here will have the right knowledge.
At work we use a few Aldebaran(now Softbank/United Robotics group) Nao Robots which they use some custom 6S li-on battery packs.
Nao robots tends to draw from the battery even if they are shut down, and the BMS tends to be a little aggresive, if the pack stays on a turned off robot for 3 months it's gonna lock and will refuse to charge.
Now, I have noticed a few things.
The "dead" battery, while connected to charger and NOT Charging will... -
I have two Milwaukee 12 amp hours battery packs that have an issue with battery cells very unbalanced these are probably over 4 years old and been heavily used in the past but now get occasionally used heavily and when I went to use the grinder tool the battery lost battery battery power very quickly so I decided to open it up and found some battery cells voltage from 3.6 to 4.1 no wonder the battery charger was not fully charging them 3 out of 4 LEDs were on meaning that it was only 75% charged
So I have put them on the battery testing machine to drain each battery cell down to... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
I have had this battery backup for at 2 to 4 years now and the battery when bad and this is weird battery size it is the same length as a 12 volt @ 7 amp hour battery however the depth of is not the same as a 12 volt @ 5.5 amp hour battery
I have several battery packs that are A123 batteries cell so I bought a lipo4 BMS balancing protection board for these batteries and I have a configuration that is 4S 3P these battery packs were 3S 2P so I reconfigured them but left the tabbing on one side of the battery row of battery cells and re-tabbed the other side to the configuration that...
