The invention relates to a high-capacity
lithium battery pack, which is provided with a
lithium battery pack (1), a charging interface, a discharging interface, a battery protection plate (2), an electric quantity indicating lamp (5), a charging fuse (6), a
temperature control charging switch (7) and a discharging fuse (8), wherein the
lithium battery pack (1) is formed by connecting a plurality of single battery cells in series; the charging interface and the discharging interface consist of female plugs (3a, 3b) and male plugs (4a, 4b); and the battery protection plate (2) is used for over charge, over
discharge and
over current protection and
battery cell voltage balance of the
lithium battery pack (1). Because the high-capacity
lithium battery pack is adopted in the
lithium battery pack, the lithium battery pack has the advantages of small volume, light weight, portability, easiness for carrying, high
power capacity, high-
energy density, high efficiency, high
bearing capacity, long cycle life, low self-
discharge rate, no
memory effect, no
pollution, excellent constant-
voltage source performance and the like; and through the battery protection plate,
adverse conditions of over charge, over
discharge, over current, over
high voltage of the single battery cells and the like are effectively prevented, the quality of the lithium battery pack is remarkably improved, and the lithium battery pack has the advantages of stable performance and long life.
