Maximum range in an ultra-compact housing. Discover a powerful bottle-type battery in a Shark casing, offering up to 1146Wh of pure energy. The pack is built in a 13S7P configuration using as many as 91 original Samsung INR18650-35E cells. The main advantage of this design is its unrivaled capacity-to-size ratio. Despite its enormous capacity of 24.5Ah, the battery maintains an extremely compact height – only 143 mm (compared to 156 mm in 25Ah versions with 21700 cells).
This allows the battery to fit into smaller bike frames, and the lower center of gravity ensures excellent stability, a more secure fit in the mount, and minimizes the risk of rail damage on uneven terrain.
Wide compatibility and versatility. The battery works perfectly with systems ranging from 250W to 2000W. It is an ideal choice for Mid-Drive systems (central motors) and gearless and trekking systems such as: Tongsheng TSDZ2, Bafang BBSHD, Bolt 500W/2000W, Rapid S2100, or solutions from Nexuna. It achieves optimal efficiency and record-breaking ranges at cruising speeds up to 35 km/h.
The advantage of Polish production over mass Chinese chemicals. Forget about unsubstantiated marketing promises. Our battery is 100% manufactured in Poland, adhering to rigorous safety procedures and quality control:
Brand new Samsung 35E cells sourced exclusively from the freshest production batches.
CNC robot welding ensuring perfect repeatability, identical pressure, and zero risk of cell overheating during assembly.
Increased safety: Use of additional insulators on positive terminals ("pluses") for full short-circuit protection.
Robust components: Proven BMS electronic systems protecting the pack from overcharging and excessive discharge, a reinforced mini XLR charging socket, and a universal XT60 power output (approx. 30 cm cable).
Real Ranges (Rider's Guide)
Forget about trumped-up marketing promises. Here's what the real range looks like on a single charge (1146Wh pack):
Full assist (Eco/Touring - 50% muscle power, 50% motor): up to 100 – 150 km
Moderate assist (Daily urban riding - 25% muscle, 75% motor): up to 75 – 120 km
Riding solely on throttle (100% motor load): up to 60 – 100 km
