Super Shark 36V 17Ah Ebike Battery - Samsung 35E Cells

Description

The battery is in good, used, working condition. It was regularly used for a 28mile commute until back issues forced me to stop riding. It has been well cared for, being stored at around 70% full with occasional top ups to keep it in good condition.

I had it connected to a 250W bafang mid Drive motor (BBS01B).

A charger, bike mounting bracket and two keys are included.

Eclipse bikes description:
'We are now offering a new range of high specification battery packs from EM3ev, who are a well established, innovative and highly regarded battery supplier.

The Super Shark downtube mounted battery pack consists of 50 x Samsung INR18650-35E (3.7V 3.5Ah) connected 10 series 5 parallel. The battery packs are assembled using only genuine A-grade cells, sourced from official suppliers. The battery cells and BMS are well protected by tough black ABS plastic casings.

Built into the battery casing is an on/off power button and an LED battery capacity indicator / error indicator. The battery can be locked into position on the bikes downtube and easily mounts to standard bike frames using the water bottle mountings.

The Super Shark 36V 17Ah battery pack is supplied with battery base, 2 x keys for locking battery onto base, high current charge plug (approx. 8A rated) and good quality fan cooled 36V 2A (42V output) charger.

Advanced Construction

EM3ev batteries are assembled using many custom parts designed and manufacture in-house, using their own CNC machines. This includes the CNC manufactured cell holders, which are specifically designed to fit the battery casings, keeping everything safe, solid and secure.

Every cell within the battery pack is fused. EM3ev have designed and manufactured custom terminations for this layout, with cell level fusing on every cell, whilst also minimising voltage drop, to make the EM3ev Super Shark one of the safest Ebike Batteries on the market.

Cell level fusing, means that in the event of an internal short circuit in the battery (which the BMS cannot protect against), then all that will happen is that 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.

Samsung 35E: ~25A Continuous, 30A Max Burst Current (BMS limited)

We do not recommend that the battery is fitted upside down. If there is no choice to fit the battery in this manner due to frame design then it would be highly advisable to use additional straps to secure the battery. We do not condone the use of the battery in this manner.

The battery pack casings are fairly water resistant (though not 100% waterproof). If regularly riding in wet weather condition, we would advise adding a battery cover, to provide additional protection from moisture ingress.'
