Victron Battery protect BP 48-100
More info
" The Victron BatteryProtect : disconnects the battery from non essential loads "
The Victron Energy BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.
Description
A special setting for Li-ion batteries
In this mode the Battery Protect can be controlled by the VE.Bus BMS.
Ultra low current consumption
This is important in case of Li-ion batteries, especially after low voltage shutdown.
Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
Over voltage protection
To prevent damage to your sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16 V respectively 32 V.
Ignition proof
No relays but MOSFET switches, and therefore no sparks.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 15 seconds. Starting the engine will therefore not activate the alarm. The alarm output is an open collector output to the negative (minus) rail, max. current 500 mA. The alarm is typically used to activate a buzzer and / or lamp.
Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
