Hi all, I'm almost ready to order but I need a teeny bit of info. Here's the deal.
I've got an Advanced FB1-4001A motor, Curtis 1231C-8601 500A controller rated at 180V max. Currently running lead pack at 144V, until you hit the throttle at which time it's a 120-130V pack!
After the charger turns off, the pack voltage drops from about 186, over the controllers rating, down to about 160 or so in like 5 seconds, plenty quick enough so I can't crank it up and blow it before it gets to a safe voltage.
I've been wondering about LifePo4 batteries and how they behave. So if you're charging at 3.85 for example, how long before the voltage drops to about 3.4 or so after the charger stops? Seconds or minutes???
The reason I'm asking, I'm able to fit 50 200Ah cells in my truck comfortably and would like to do so for maximum range, minimal C draw and to maximize cell life.
