【Multi-Protocol】DALY 250A Smart BMS for LiFePO4/Li-ion Batteries | 4S-16S Battery Management with CAN/RS485 & Bluetooth GPS | 40A-250A Industrial Grade | Remote Monitoring & EV Compatibility | COD Shipping

•Battery Type CompatibilityLithium-ion battery: 3.7V nominal voltageOvervoltage threshold: >4.25V (Under voltage: 3.75V (Under voltage: Consequences of mismatched selection: BMS/battery burnout, incomplete charging/discharging, BMS failure.

•Number of Battery StringsThe BMS’s number of protection channels must match the battery pack’s wiring configuration:3-string BMS 3-string batteryX-string BMS X-string batteryConsequences of mismatched selection: BMS/battery burnout.

•Continuous Current SelectionFormula:Power (W) ÷ (Number of battery strings × Over voltage) = Max. output current Select a protection board with a current rating higher than the calculated max. output current (recommended 1.5–2× multiplier).Example: For a 400W 13S ternary battery:400W ÷ (13 × 2.7V) = 11.39A Factoring in motor error (up to 1.5×): 11.39A × 1.5 = 17.08A Recommended: 20A protection board.Consequences of incorrect selection: Oversized current wastes resources; undersized current damages BMS.
