Protection functions

• Over-temperature protection: charger reduces output or stops charging if internal or ambient temperature exceeds safe limits (stops when >65℃ until cooled)
• Reverse-connection protection: internal circuit disables output if batteries are connected with reversed polarity
• No-load protection: no output when batteries are disconnected
• Short-circuit protection: internal shutdown on short; restart only after fault clearance and restart
• Automatic full-charge cutoff: charging stops when battery is detected as fully charged
