I am guessing the vast majority off us run our ebikes (not charging voltage) somewhere in the 36V to 60V range, but curious to know how many "High-Volters" there are...
Currently, I have one bike at 7S (<30V), two bikes at 12S (44.4V Nominal) and my newest project in the works will be either 20S or 24S.
 
I moved up to 16S from 12S-15S RC Lipo and it's been a surprisingly sweet spot for my bike packs. 4 x 4S bricks series wired makes for simple CellLog monitoring/logging.

56-66V is a useful voltage range - most stock 48V controllers will require upgraded caps but everything else seems to work well.

28v for a standup scooter, 36v for an ebike, 48v for an ebike, and soon 6s LiPo (24v) for an eskateboard & 48-72v (12s-18s LiPo) for an ebike.

They all use different chargers. Each of those chargers uses a different output connection. :roll:
 
So far, it appears that a 20S (74V Nominal) Set-up is a preferred set-up vs. a 24S (88.8V Nominal) - I have to wonder if this is because of the typical 100V Cap & FET limits of 4110 Controllers. Anyone running 24S on a 4110 FET Controller??? -
 
I'm currently running 18S on my DH bike because a string of 6S cells was taken out of commission. But I normally run that bike at 24S.

Then, all my other bikes are 12S. It makes it easier for charging when you run 2P on everything and have 12S chargers (with 6S packs). My 12S charger can charge ALL of my packs with the proper harnesses. I make a series discharge cable that can quickly be changed to parallel charge cable with the addition of one extra piece.

I plan on changing the 24S charger to a multiple voltage 12S/18S/24S charger

What controller are you running the 24S pack with?

I run both packs using the same controller, a Lyen 4110 18FET that I had him make for 24S or 18S. No controller LVC, it's all done by CA.
