52v 19.2ah 21700 Cell Jumbo XL Hailong Shark Battery

    The Jumbo XL Hailong Shark Pack is a just a little taller than the standard jumbo version, with a larger capacity. This battery is made with top of the line 21700 Cells, the new gold standard since 18650. Typically installed on your downtube to the water bottle cage mount, this battery quick releases from a reinforced mounting bracket. Some people make a backpack battery with these, others fit them inside a bike frame bag, place them on a rear rack, or in a pannier. If using with a recumbent/trike, they mount great on T-Cycle and other available Battery Mounts.

- This battery is a whopping 998.4 watt hours. On average riders use around 20-25 watt hours per mile. You can expect 45+ miles range from this pack (with lower power/assist you can get upwards of 90 miles).

This pack is suitable to power any 52 volt system that requires 30 amps or less of continuous discharge. This includes all 52v TDSZ2 and 48/52v BBS models, and most basic 48/52v Hub Motor Kits - however, be sure to always refer to your specific system amp requirements when choosing your battery.

- This battery features our custom BMS which allows charging through the discharge port ~ for full compatibility with our Eco Cycle Dual Battery Balancer which allows you to link 2 batteries together with 1 line going to your motor, and 1 charge port for easy charging of both batteries (although you can still charge independently through the stock charge port as well)

- This Battery has an XLR 3 Pin Charge Port, and includes a 5 Amp Charger. The Discharge cable uses an XT90s Anti-Spark Connector (fully sheathed with no exposed wire), however we have a variety of Adapters available for easy pairing with whatever motor/kit you plan to use it with. As with all our products, this is covered by our Comprehensive Warranty and Extended Support Plan.
