How to control the output current of lithium battery

power supply

The DC-DC will only output the current required to maintain 3.3v and nothing more. If your load is 100mA then only 100mA will be sourced from the battery regardless of the capacity of the cells. You should consider though that 81aH is a very large amount and this many batteries in parallel likely has the capability to output a considerable

amperage

For your 9.6V battery you get current less than 1A (1C rate) if the resistance is more than 9.6 ohms. If resistance is less than 3 ohms you are probably discharging your battery at too high a rate. Ground the output with a current sense resistor and use a solenoid or relay as the inductor and it is similar to the original circuit above.

What is a battery current control system?

The current control system is commanded by a superimposed battery voltage controller aimed at bringing the battery terminal voltage to the fully-charged state while also limiting the maximum battery charging current.

How to reduce battery life?

Second, cycling charge in and out of the battery reduces battery life. To minimize this effect, it is best if the load draws power directly from the supply rather than through the charger. It would be relatively easy to implement a power bypass by adding a bypass power switch between the input voltage and the supply to the load switching regulator.

Does lithium-ion battery interfacing DC-DC converter work?

Lithium-ion batteries are becoming increasingly popular for energy storage in various hybrid energy systems, hybrid ac/dc, micro-grid, e-mobility applications.
