DALY Li-ion NMC 20S 72V 40A Waterproof Battery Management System - BMS Protection Board
Daly 20S 72V 40A is a Lithium Battery Protection Board (PCM BMS) for balance charging. It uses an A-level protective integrated circuit IC. Its high load capabilities and 40A continuous discharge current performance make it a reliable solution for battery packs. It features a power MOSFET with a high voltage resistance and a low inner resistance. The heat sink will significantly aid cooling.
IC itself has a power balancing function though the circuit is simple and reliable. It features typical voltage detection for each cell. So, that each battery will be prevented from overcharging or over-discharge conditions. This BMS has reliable Over current and short circuit protection function due to which long time short circuit of the load won't affect the PCB and the battery.
Continuous temperature monitoring through NTC and thermal protection during charging and discharging.
Extremely low power consumption and the current consumption of the whole device is less than 100uA.
This BMS uses a high anti-corrosion, high water resistance, and high impedance ESD conformal coating.
Features:
- State of charge calculations.
- Cell over-voltage and under-voltage protection.
- Intelligent battery balancing (passive).
- Fully sealed waterproof technology, with waterproof, dustproof, shockproof, anti-squeezing, and other protective functions.
