Hello Builders, my name is Konstantin and I work at Energus PS. This is our introduction to the community and I will be representing Energus PS here so please adress all questions to me directly. Or by Email: [email protected] We are a small European company(Lithuania) specializing in production of a modular 18650 cell type pack solution. The modules were initially designed for Formula Student Electric (www.formulastudent.de/teams/fse/)(The University of Melbourne, MUR Motorsports.

With this Demo Build we want to introduce our Battery Modules to the eSk8 community. The Pack: 10S3P configuration was chosen as a perfect fit for 12S2P BATTERY ENCLOSURE V2 purchased online. Samsung 30Q cells were chosen as most popular eSk8 cells. 3mm rubber sheet was glued to the bottom of the enclosure for cell protection and vibration isolation. 4 side cuts on the enclosure allowed it to become flexible enough to match the Dec flex. 12AWG wire connections between the modules for flexibility
The Module: • Low weight: 267 Wh per kg • Individually fuse-protected cells, no parallel fusing is required • Ultra low self-discharge • No initial balancing required • Rapid prototyping of battery pack • Convenient thermal control • Built from genuine SAMSUNG 30Q cells • Low flammability: UL 94 V-0 rated • Analogue, 2-wire, 2-point temperature sensor • Nominal capacity: 12.4 Ah / 44.6 Wh • Nominal voltage: 3.60 V (2.50-4.20 V) • Volume: 0.122 liter • Weight: 174 g
The BMS: In-house developed “Tiny BMS s516 – 150A/750A”
Features: • Android APP • Very small dimensions. • Flexibility: 4 to 16 cells of any kind, including Li-ion, LiPo, LiFePO4, Li-Titanate and Li-sulfur chemistries • Current measurement and SOC calculation. • Firmware updates, new feature releases and improvements for free. • Bluetooth connection (good for USB replacement). • Event logs and live data view: easy to debug the system, check what happened and when. • External contactor support for charger and load. • External current sensor support up to 750A. • Faster balancing due to “early balancing”, which saves charging time. • Ignition/enable input. BMS will switch off the output and go to low power mode when no signal on certain pin (if enabled). • Temperature measurement in multiple points of the battery - for safety, to prevent overheating and charging in cold.
Specifications: • Series cells: 4 to 16 • Cell voltage: 0.80 to 4.50 V • Cell balancing: 150 mA, dissipative • Discharge/Regen current peak: 150 A** • Discharge/Regen current sustained: 60 A** • Charge current peak: 100 A** • Charge current sustained: 30 A** • Discharge/Charge/Regen current: 750 A* • Interface: UART (USB / Bluetooth / CAN) • Up to 64 channel temperature sensors (available in Energus Cell Modules)
