The decision whether to install a relay o one booster in a motorhome it depends on your needs, las vehicle needs and budget.
Relay:
- Advantages:
- More economical: Relays are generally cheaper than boosters.
- Easy installation: Installing a relay is relatively simple and can be done on your own..
- Protects the auxiliary battery: A good quality relay can protect the auxiliary battery from overvoltage and excessive discharge.
- Disadvantages:
- less efficient: Relays are not as efficient as boosters for charging the auxiliary battery.
- Does not increase voltage: A relay will not increase the auxiliary battery voltage, which can be a problem if you have many devices that work with 12 V.
Booster:
- Advantages:
- More efficient: Boosters are more efficient than relays for charging the auxiliary battery.
- Increase the voltage: A booster can increase the voltage of the auxiliary battery, which is useful if you have many devices that work with 12 V.
- Faster charging: A booster can charge the auxiliary battery faster than a relay.
- Disadvantages:
- More expensive: Boosters are generally more expensive than relays.
- More complex installation: Installing a booster can be somewhat more complex than that of an automatic relay and you may need help from a professional..
