|Applicants:||YAMAHA HATSUDOKI KABUSHIKI KAISHA
|Title:||LITHIUM ION BATTERY PACK|
Provided is a lithium ion battery pack that can be used in place of a lead storage battery, and that differs from previously proposed lithium ion battery packs. A lithium ion battery pack (10) is provided with first through fourth lithium ion cells (121-124) connected in series. The voltage (FV1) when the charging rate of the first lithium ion cell (121) is at 100% differs from the voltage (FV2) when the charging rate of the second lithium ion cell (122) is at 100%. The initial voltage of the lithium ion battery pack (10) is set within the range of 14-15V.
