- | There are hobbyists who build **4S packs** and undercharge the cells to only 3.7v. This gives an operating range of 14.8v - 12v, a much better fit for nominal 12v systems. The downside is this configuration only uses 58% of the cells' capacity and will require more cells to achieve the same amount of Ah. | + | There are hobbyists who build **4S packs** and undercharge the cells to only 3.7v.
