ANT BMS Smart BMS 17S-24S 52V-88V 50A-420A Battery Protection Board w/ Bluetooth, RS485/CAN

OverviewThe ANT BMS Smart BMS is a battery protection board for 17S to 24S battery packs (52V–88V range commonly used), suitable for Li-ion, LiFePO4, and LTO chemistries. It integrates Bluetooth (Android/iOS) monitoring and supports the same-port wiring method, with multiple current options from 50A up to 420A continuous (model-dependent).Key Features Series support: 17S to 24S Power supply mode: Battery pack self-powered and 20–100V DC input Cell voltage detection: 0–5V, error <20mV over full operating range; typical error value <10mV Single cell voltage dropout detection: Supported Balancing: 100mA passive balance current Short circuit protection: Supported (adjustable) Bluetooth: Built-in; supports Android / IOS phone Temperature detection: -40 to 125°C Total voltage detection: 0–100V, <0.5% FSR (FSR = full scale) Current sense shunt: -150A to 300A, error <0.5% FSR SoC estimation accuracy: Error <8% (operating conditions) Battery remaining capacity error: Less than 8% Total Cycle AH: Cumulative value is half of the charge/discharge value Operating power consumption: <4mA (without communication) / 15mA (485/CAN) Standby power consumption: <2mA Operating temperature: -40 to 85°C Storage temperature: -40 to 95°C SpecificationsElectrical (by variant) Variant (17S–24S) Continuous Current Maximum Discharge / Peak Peak Duration Option 50A 125A Peak max 10 seconds Option 100A 250A Peak max 10 seconds Option 130A 325A Peak max 10 seconds Option 170A 425A Peak max 10 seconds Option 220A 550A Peak max 10 seconds Option 340A 850A Peak max 10 seconds Option 380A 950A Peak max 10 seconds Option 400A 1000A Peak max 10 seconds Option 420A 1050A Peak max 10 seconds Mechanical (selected variants)Note: The data tolerance range is ±1mm.
