The condition happens in the time of probably milliseconds. Half the time, the instrumentation doesn't even pick it up. Sometimes it does and that's how I figured out that was the problem.
We can't fit anymore battery in the space we have. We also don't have the budget for another lithium...
We realize the problems with these batteries. That's why we want to minimize the occurrence of the undervoltage condition using capacitors or some other method. We have little to no experience with power electronics and researching hasn't given me any useful information.
I am currently running a DC motor in an electric vehicle. A lithium polymer battery powers a motor controller which is connected to said DC motor to drive the car.
The lithium polymer battery as you would imagine has a battery monitoring system on it. One of the conditions it protects against...
