This depends on the application. We always recommend an energy efficient relay which consumes few energy when turned on.
Recommended relays
| Pack voltage | Maximum current | Relay | Note |
|---|---|---|---|
| 12V | <120A | 123\SmartRelay 120A | |
| 24V | <= 100A | 123\SmartRelay 120A | |
| 12V/24V | >120A & <500A | TBS Battery Protect Relay | |
| 48V | <100A (200A for 1 minute) | 123\PowerSwitch 48V 100A | |
| All voltages | <500A | Kilovac EV200 | Coil voltage up to 96V Consumes about 50mA, which is much more than the ~1mA of the 123\PowerRelay and the 123\PowerSwitch |
