In case anyone is interested in visualization and timing of charging, Justin at Grin Tech provides a nice simulator -

Let's break it down for PastorDave.
.
I served aboard the USS Thomas Jefferson SSBN 618, 1967-1970. I think I'm just a little bit older than you are. We are still boomer brothers of the phin! I'll be checking in with you regarding my RCS soon after I get started riding and figure out what I don't know. I've got the satiator charger but I haven't set it up yet. I like the idea of charging up to 80% and not discharging below 20% when you don't need the full range capability of the bike. I would like to learn how much benefit you could expect from charging at the lower 2 amp rate with the basic charger that comes with the bike instead of the standard 4 amp rate, or even the fast charge rate of 7 amps with the Grin satiator charger.I have to admit, I am. Pictured on the USS Kentucky in 2016 somewhere in the Pacific. I have the 52V CCS with Marathon Plus tires, an unfortunately rare combination between the CCS and CCX lines. My wife has a RCS.
Those Satiator chargers are the nazz and I'm sure you'll enjoy using yours.I served aboard the USS Thomas Jefferson SSBN 618, 1967-1970. I think I'm just a little bit older than you are.

Have any of you math guys ever calculated an average minutes per volt charging guideline? ? For instance if I am at 43.3 and I want to go to 53.3...how long should I set my timer for? Or is this an oversimplification? (I have a 48/12 battery).
Thank you so much for that insight. I didn't even think of a performance difference but that does make sense and I would be willing to trade some performance for a little less total battery lifeThose Satiator chargers are the nazz and I'm sure you'll enjoy using yours.
Let me suggest that you try charging the bike at 85%, 90%, and 95% also, just to see what the performance of the bike is like. You don't get the same level of performance at 80% that you do at a higher level. The bike is zippier and a lot more fun. You might decide that this is worth it. The battery won't get the same longevity, but you might decide it's worth it to get the most out of your bike. If you find a sweet spot at, say 90% (just an example, not an estimate of where that sweet spot really is), then the battery will still last longer compared to charging up to 100%.
Suppose you only got 4 years of service from the battery instead of 5, but your enjoyment of the bike was significantly higher. It's a question worth thinking about.
I have a 48 volt battery. At 80% the bike's response is already noticeably lower. Not bad, far from awful, but definitely not what it is at 95%, which is what my stock charger provides. I'd really not want to miss that higher 15%. With a 52 V battery, those figures would definitely change and I'd have to experiment to find the sweet spot.
Oh wow! That is exactly what I am looking for! Thank you!Also, Pastor Dave, you might take a look at Post#18 in this thread and a chart by Surfstar which might give you some insight of how it works for him.
After 250 miles on my CCS I totally agree with this observation. The top 20% is where the real fun is!Those Satiator chargers are the nazz and I'm sure you'll enjoy using yours.

Seriously? There have very few changes in chemistry over the last 5 years. PF, Panasonic B and more are old and still reliable. We’ve had few if anything new filter down to eBikes. I’m confused about the point you’re making.Most are pushing 10. The manufacturing process and changing chemistry every year
