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 a very secure mount. Its sleek power packed 52 volt 17.5 Ah 910 Wh 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.
The LG_MJ1 cells perform slightly better than Panasonic GA cells and are preferred by NASA. See link below for NASA test results.
