I'm working in a discharger of LiPo batteries that must discharge at rates of 100 amp
QuoteI'm working in a discharger of LiPo batteries that must discharge at rates of 100 ampSo is this an incendiary device then. What is to stop the battery bursting into flames?

What is to stop the battery bursting into flames?There are special Li-Po packs that are designed to supply that kind of current discharge (for a short time of course) used in high performance R/C electric motor powered craft.http://www.rcgroups.com/forums/showthread.php?t=1617674Lefty
Using a relay:https://www.sparkfun.com/products/100
Depends on what you mean by 'manage'. If you just need to be able to measure the current I think there might be hall effect current sensors that can measure that range of currents and give you a simple DC measurement voltage proportional to the current flow. If you mean to turn on and off or regulate the actual current flow then that is another matter all together. One could use very high current rated relay contacts if just switching on or off that level of current, although the size of relay would probably be pretty massive. There are some IGBT high current transistors rated at that kind of current, and of course one could parallel several high current/power MOSFETS to get that kind of current control. Pretty demanding application, I would look around and see what other people and firms have used to perform that task first I think.Lefty
And sometimes they do burst into flames
