Protection Circuit Module (PCB) for 20S (24V, 7A limited) NiMH/NiCd Battery Pack with 65C thermostat and Fuel Gauge Socket (#7049)

Protection Circuit Board with 65°C thermostat and Fuel Gauge Socket For 24V NiMH/NiCd Battery Packs 

Features:   

• This protection circuit is specially designed for 24V NiMH/NiCd Battery pack with upto a max of 7A discharging rate.
• Keep 24V NiMH/NiCd Battery pack from over-discharge (20V)
• Max discharging /charge current <7A.
• Over discharge protection: 20V±1V
• Power consumption: 1.5mA (No LED Fuel Gauge added)
• No over-charge protection
• Must use the correct voltage charger to properly charge the battery pack!
• Has short circuit protection during discharge
• With 65ºC thermostat and Fuel Gauge Socket
• Please find Fuel Gauge for 24V Nimh/Nicd Battery Pack here
• To reset the PCB:
• Connect a 24V charger to "Reset" the pcb once the pcb is open when battery pack voltage drop below 19.4V
• If you have a multi-voltage charger, it might not "reset" the pcb, you can "reset" the pcb by:
• Connect the charger directly to the Batt+ and Batt- of the pcb
• If you cannot remove the load, then you can add an on/off switch like this to "reset" pcb and start charging:
• battery-------->pcb------> switch --------->load
                 |
                 |—>charger

• Dimension (LxWxH): 60mm(2.4") x 30mm(1.2") x  6.10mm(0.25")
• Weight: 11 grams (0.4Oz) 
• Working Temperature: 60±5ºC

How to connect PCB on battery packs

• Bat+ = 24V Positive = Input Positive
• Bat-  = 24V Negative= Input Negative
• OUT+ = Vout+ = Charge + / Discharge + = Output Positive
• OUT-  = Vout-  = Charge - / Discharge - = Output Negative
• 

Warnings

• Misusing PCB may cause battery damage or explode.  We are not responsible for any damage caused by user.
• Don't use this PCB with Li-Ion / LiFePo4 battery pack
• Must charge battery up to 24VDC minimum
• Must disconnect load from PCB to "Reset" PCB before charging
• Since this PCB does not have over-charge protection function, must use our 24V NiMH/NiCd smart charger to recharge 24V battery pack.
