What Safety Features Do CZW Lithium Iron Phosphate Batteries Include?
Built-in Battery Management Systems (BMS) prevent overcharge, over-discharge, short circuits, and thermal runaway. Stable LiFePO4 chemistry resists combustion even under puncture or extreme temperatures (-20°C to 60°C operating range). Flame-retardant casing and cell separation technology further enhance safety for marine and RV applications.
The multi-layered protection system includes real-time monitoring of individual cell voltages and temperatures. Unlike traditional batteries, CZW’s BMS automatically disconnects during critical events like sudden current surges or cell imbalance. For marine environments, the IP65-rated enclosures protect against saltwater corrosion and moisture ingress. Thermal management pads between cells maintain optimal operating temperatures, crucial for maintaining capacity in fluctuating climates.

How Does CZW’s Modular Design Simplify Capacity Expansion?
Built-in 120A busbars enable parallel connections up to 4 units (e.g., 48V 400Ah x4 = 1600Ah). Plug-and-play wiring harnesses maintain voltage balance across packs. Expansion requires matching battery firmware versions and identical charge/discharge rates across all units.
