relay
Each 48V battery pack''s Vout will go through a 200K/20K voltage divider circuit to lower the voltage across the 20K resistor to 3.6V - 5.5 V depending on the current battery voltage (40V - 60V, depleted or charging); the lowered voltage will then drive the gate of an IRF510N Mosfet.

Frequent battery failure on G60 protection relay
Pull Tab/Replace" alarm? Or something else? The battery should last 5-6 years in a G60 in service and 3-4 years sitting on a shelf not in use. The battery is *not* just used "for clock issues." It is used to power ROM in case of power supply failure. If the battery is dying in 2 months, I''d start looking at your power supply...

relay
Stay the module, keeps the circuit cleaner and you would need more complex curcuit to handle relay operations. If you are that worried these two options might help: A. Insert a diode to block the oncoming current (to the battery from module) to keep the module from charging the battery (people do this in pinball ram mods).
How do relays work?
What are relays? A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current.. The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it). You can think of a relay as a kind of electric lever: switch it on …
