Cell Count – LiPo Battery

The cell count of a boat is best selected depending on the total length of the hull. Following this general chart will determine a cell count for a specific hull length while providing best speed, performance and handling for the power.

 

Hull Length LiPo Cells Min. Capacity / C Rating
20”-24” / 55cm-68.5cm 2 cell LiPo 5000mAh / Min. 25C
25”-26” / 63cm-79cm 3 cell LiPo 5000mAh / Min. 25C
27”-34” / 69cm-86cm 4 cell LiPo 5000mAh / Min. 25C
33”-40” / 86.5cm-101.5cm 6 cell LiPo 5000mAh / Min. 25C
40.1” + / 102cm + 8-12 cell LiPo 5000mAh / Min. 25C

 

1P recommended for the smaller length in each range, low current consumption with lower kv.
2P recommended for the larger lengths in each range, higher current consumption and kv with increased reliability.

S = Series. When cells are placed in series voltage adds up, capacity remains the same.
P = Parallel When cells are placed in parallel capacity adds voltage remains the same. Paralleling packs will extend run time, increase maximum continuous draw, increase reliablilty and decrease pack heat accumulation.

This is only a general guide chart and does not mean you can’t use 8 or even 10 cell LiPo on a 35” hull vs. the spec’d 6s.

NOTE: Paralleled packs does not increase the C rating. C rating is a given rating and can not be changed. Paralleling packs doubles capacity, which doubles available constant current.
