7740Re: Lithium voltage sag
- Dec 7, 2011Paul very useful info.
Are you still seeing the same volts as mention in the blog post on the TS pack when under load. I see you only used 48 cells and my plan is for 52. You said you would do 50 next time. Unless I messed up my math the CALB 100 should fit with a 52 count.
I'll likely never do a 2600 foot climbing grade but I'm impressed that you do it regularly. Do you leave plenty of charge space for a regen down the hill or fill it up at home?

The first half is 1% ~ 2% uphill grade (45~50 mph speed limit) and the last half is 6% ~ 7% (I keep it between 30 and 35 mph, like most gas cars) on a very curvy road. The Force uses 32 ~ 34 amp hours to get home. I always head home with a full charge. I use Normal mode because if I switch to Power mode I will quickly sag some cells to 2.6v or less. I set my lowest cell under voltage alarm at 2.704 volts and I can quickly trip that alarm in Normal mode if I floor it....... .......
