Here is the datasheet of lead acid batteries.

what does is maximum permissible current means? Is it in ampere or milliampere?
That is what I am asking. If one of them is always open, then how does the current flow from batter to pack or pack to battery? Current needs to flow through both of the MOSFETs while charging or discharging.
Thank you for the reply. But my question was, aren't these FET unidirectional? Can current flow from source to drain? Because whether current flows from Battery to Pack or Pack to Battery, current has to flow through both FETs, isn't it? So, if they allow current to flow in only one direction...
This is a schematics for Li ion Batterry gauge. https://i.imgur.com/0k8r5XZ.png?2 The current flows from battery to pack when discharging and from pack to battery when charging. I understand that current are controlled by the FET which act as switches but don't understand how they work here. Can...
I want to use bq24753A (https://www.ti.com/lit/ds/slus920/slus920.pdf) battery charger to charge 2 LiPo in series. But my input voltage can vary from 9V to 15V. Will it cause any problem because there are some pins whose voltage depend on input voltage. But the charger also has a buck converter...
I have a battery pack made of 3 LiPo cells (3.7V each. total 11.1V). I want to design a circuit which can charge this battery with an ac-dc adapter of 15V. When adapter is connected, adapter should charge the battery as well as drive another system (load). When the adapter is not connected, the...
I have to charge a 7.4V battery of 2500mAh with 12V dc. What should be the current output of the power supply? what is the mathematical equation for this?
If I want to charge the battery with another similar battery, how efficient will it be?
I found the libraries. But there are very few components in the library. There is a library called Miscellaneous-devices.intlib, there are few resistors, and only SMD resistor is 0603. I need other packages.
I just moved from Eagle to Altium. In Altium, I also don't find footprints for SMD resistors. I couldn't find any download button in the above link. Do I need to create footprints for each kind of resistors?
This is a circuit of an active electrode for EEG (electroencephalogram) amplifier. I am trying to understand the circuit.

My question is:
What C1, C2, C5 and R3, R4 do? Some explanation would be helpful.
