Li-Ion: This is a catch-all lithium ion representative of most 18650 type
lithium cells. The majority of ebike lithium packs are best represented by
this option
LiPo: This represents standard discharge rate ebike grade lithium polymer
cells, which show a fairly steady drop in voltage as the battery is drained
from 4.2V to 3.0 V/cell.
RCLiP: This is for high discharge rate polymer batteries typically used in
radio controlled models. They have a much lower drop in voltage over the
course of their discharge than regular ebike grade LiPo.
LiFe: This is for Lithium Iron Phosphate batteries, be they pouch cells (like
PING), or cylindrical cells (Like Headway, A123 etc). Iron phosphate cells
have a very flat discharge curve, but at a lower voltage than other types of
lithium (3.3V versus 3.7V nominal)
SLA: This is for lead acid batteries, whether sealed or AGM etc.
NiMH: This is for Nickel Metal Hydride or NiCad packs.
The majority of commercial lithium ebike batteries are represented with the
standard Li-ion profile, but the LiPo profile can be used if the SOC icon shows a
flat battery when there is still capacity remaining. The relationship between open
circuit cell voltage and battery SOC for each type is shown in this graph.
