Description
The More Poweeer Electric 52V 17.5Ah Jumbo Shark battery is one of the highest power and best 52V packs available in Australia. Made with Panasonic NCR18650GA 3500mAh cells and a 50A BMS, it is capable of up to 4kW of power.
Why choose the Jumbo Shark battery?
Many 52V packs on the market use smaller BMS units that limit current and cut out under load. The Jumbo Shark battery has a 50A BMS with O2 IC, so it can deliver the current that high-power e-bikes need. If you want to run a 4kW+ bike such as the SEM Venom or another high-power e-bike, you need a battery capable of 50A – and that is exactly what this pack is built for.
- 52V 17.5Ah battery pack
- Panasonic NCR18650GA 3500mAh cells
- 50A BMS with O2 IC
- Capable of up to 4kW of power
- 35cm discharge wires with XT90 female connector
- Includes a 58.8V 4A aluminium charger
Do not confuse it with cheaper packs
Cheaper 52V batteries often use lower-grade cells and lower-rated BMS units. They may look similar, but they cannot deliver the same current without cutting out or overheating. The Jumbo Shark battery uses quality Panasonic cells and a high-current BMS for reliable high-power performance.
Fitting tips
- Check that your controller is rated for 52V and your wiring can handle the current
- Mount the battery securely so it cannot move or rub on the frame
- Connect the XT90 lead firmly and make sure polarity is correct
- Charge with the supplied 58.8V 4A charger before your first ride
Battery care tips
Lithium batteries last longest when they are looked after. Avoid storing the battery completely flat or fully charged for long periods – around half charge is ideal for storage. Charge in a dry, ventilated area away from flammable materials, use the correct charger for your battery voltage, and never charge a battery that is damaged, swollen or has been submerged. Let a hot battery cool down after a hard ride before charging.
