The all new Hailong-3 features several upgrades the Hailong-1 aka Shark packs do not have. The Hailong-3 has an on/off power switch, USB 2.0 port, 3 pin charger connector, keyed locking pin, improved mounting base with adjustable metal bracket and an optional third hole for very secure mount. Its sleek power packed 48 volt 17.5 Ah profile is much smaller than the Reention Tigershark and will fit on virtually any bike the Hailong-1 battery will fit on. If you are looking for the smallest bolt on battery with the most capacity, the Hailong-3 is clearly the winner. Includes mounting bracket. Requires 3 pin charger.
