810Wh Bottle Mount Battery 48V 13S 5P Jumbo Shark

48V E-Bike Battery incl. Slider

The bottle mount batteries with many nice features:

• big fixing area on the slide
• strong material of the housing
• CNC cell holder
• custom nickel terminations for level fusing
• Smart BMS with Bluetooth and temperature control
• charge plug for up to 8A

This article does not include the charger - you can find the matching charger below (Accessories).

The Shark style case is a popular choice, due to it’s small size for it’s relatively high capacity. It’s long, but sleek profile, means it can fit into most frames and it looks pretty good. 48V (13S) and 52v (14S) Batteries are often used for the Bafang BBS motor and have a charging end voltage of 54.6V.

This case offers some nice new features:

• The Jumbo Shark case is built and designed for 48V 5P with 65 cells, including BMS and CNC cell holder which keeps everything safe, solid and secure.
• The quality and construction of the injection moulded case has improved and offers a material thickness of ~3.3mm or more and there are numerous supports within the case, to improve rigidity and strength. The tabs on the base of the Jumbo Shark case are ~5mm thick and well supported. There are 8 of these stronger tabs and they are more evenly spaced along the entire length of the battery. The estimated charge can be seen on the LED bar and has a integrated switch. Press it for 2 seconds to turn it on and off.
• The controller case in the slider (that most do not even use) has been removed. The lockable slider is solidly constructed with metal support and has more fixing points that match most water bottle mounts. You shouldn’t have any trouble to fit it on most bikes. The slider can be used for both 4P and 5P batteries. With Anderson 45 plug for discharge and 20 cm wire.
• With custom nickel terminations every cell in the pack has level fusing. Means that in the event of a serious accident, abuse or an internal short circuit in the battery (which the BMS or pack fuse cannot protect against), then some sacrificial links will safely open, preventing any of the cells or cabling from overheating and becoming dangerous. CNC spot welding ensures consistent weld quality and weld position. Safe by design!
• A high tech Smart BMS is used, which is rated for genuine 35A continuous plus, with a over-current trip set to >60A. With the BMS you can view various battery data, such as: cell voltage levels, temperature, instantaneous charge/discharge current, capacity (genuine SOC, measured Ah and remaining Ah), data log, error indication (on matching LED panel) and it all links to your phone with a continually updated and improved App. The BMS balances during charging and therefore doesn’t require a full charge in order to balance. Auto power off function, auto power on and with a pre-charge function (no sparks, so long as the battery is powered off when linked to the controller). This 2 wire type BMS costs more (it requires more mosfets) than an equivalent 3-wire type, but it means that the battery can be safely paralleled with another equivalent battery and also means it is fully protected against over-charge in every situation (impossible with a 3-wire type BMS that are generally used in this application).
• Comes with a high current charge plug, rated for around 8A. The 2-wire type BMS can safely charged through the discharge leads as well.
• 18650 A-grade genuine cells from official sources

Jumbo Shark 48V Ebike Battery Technical Information:

• Optional charger can be found below or in the category "Chargers"
• Like with any Li Ion type battery, best long term performance is obtained by not using all of the available capacity all of the time (completely empty and full). Cycle life is extended by charging to 90%.
• Cycle Life will be reduced if the pack is regularly used at continuous high discharge rates (BMS does have over-temp protection if the battery gets too hot and the battery temperature can be seen in the BMS App). Therefore, please match the battery pack to the rest of the kit to get the performance and long term usage you expect. Recommended Max Discharge Current for each Cell Type of the Jumbo Shark 48V Ebike Battery:
  Samsung 35E: ~25A Continuous, 34A Max Burst Current
  Samsung 30Q: ~38A Continuous, 55A Max Burst Current
  Samsung 33Q: ~23A Continuous, 30A Max Burst Current

Note: the cell manufacturers specs are higher than our recommendations above. It will not harm the battery to occasionally discharge at higher levels than our recommendations, but regular, sustained high discharge rates will degrade the battery more quickly and the battery voltage will sag at these high power levels. The Battery BMS is programmed to trip if cell temperatures reach 60°C during discharge and 45°C during charging.

Realistic Capacity Specs for each Cell Type of the Jumbo Shark 48V Ebike Battery:

The conservatively capacity of the cells is 3.4Ah (Samsung 35E):

• Samsung 35E: 48V nominal, 17.0Ah, ~816 Whrs.
  

Note: the above figures are on a new battery in warm weather and at a discharge rate of ~0.5C. Cold temperatures or high discharge rates will result in reduced capacity. Capacity will degrade over time and usage. 52V batteries means 14 series of 3.7V nominal cells (14*3.7V = 51.8V), but nominal should be calculated with 3.6V, which is 50.4V nominal.

Jumbo Shark 48V Ebike Battery Weight and Dimensions:

• Dimensions: 88 mm thick, 113 mm tall, 368 mm long (see also PDF in download area for a 1:1 print)
• Weight: approximately 4.5 kg for all cell types (including slider)

Does this battery fit into the frame triangle of my bike?

Here you will find a template to print and try out.

We recommend to use 3 fixing points for the battery, bottle mounts on frame are not really made for this weight. You can drill one more hole in the frame with thread, use cable ties or the Bottle Bob.

Batteries must be protected against mechanical damage, overheating, short circuit, deep discharge, overloading. Charge always under observation in dry conditions. Battery isn't completely waterproof, we recommend to avoid heavy rain and high water pressure.
