"s" stands for "series", specifically cells in series.
The typical SLA 12V battery is actually comprised of 6 - 2V cells = 6s.
1 - 12V = 12V = 6s
2 - 12V = 24V = 12s
3 - 12V = 36V = 18s
4 - 12V = 48V = 24s
The difference is that Lithiums are typically produced as singular cells, then packaged into "packs".
LiFePO4 and variations are rated at 3.2V per cell.
4s = 12.6V.
8s = 25.2V
12s = 38.4V
16s = 50.4V
Lipo - Li-ion and certain other formulations are typically 3.7V per cell.
3s = 11.1V
6s = 22.2V
7s = 25.9V I use 7s on the 24V eZips (oem 24v controller works fine with the 7s = 25.9V - 29.4V fully charged)
10s = 37V
12V = 44.4V
13s = 48.1V
Most "Lithium batteries" are labeled similar to 7s 10p
"p" standing for "parallel".
A 3.7V 2600mAh cell run 7 in series would be a 25.9V 2.6Ah battery. - 7s1p
10 of these batteries run parallel would be a 25.9V 26Ah battery. - 7s 10p
