A: For instance, with a 20S 60V 100A protection board, "same port" means your charging negative and discharging negative are connected at the same point (P-). They share a common interface, so both the charging current and discharging current are 100A. On the other hand, "different port" means the charging negative (C-) and discharging negative are separate (P-), connected at different points on the protection board. Thus, the charging and discharging currents can differ—discharging at 100A and charging at 100A. Q: Relationship Between Battery Capacity and Protection Board Current Q: What kind of charger should I choose? A: For lithium batteries, you must use a charger specifically designed for lithium batteries. Never use a lead-acid battery charger, as it could potentially exceed the protection board MOSFET's voltage tolerance, leading to overcharging without protection. For lithium iron phosphate batteries, charger voltage = number of series cells * 3.65V; for ternary lithium batteries, charger voltage = number of series cells * 4.25V. ## Features - Enhanced Safety: Safeguard your battery with protection against overcharging, overdischarging, overcurrent, short circuits, and temperature extremes.
