I am looking for an inexpensive battery voltage monitor with high and low voltage alarm. I have found a couple, but they are very expensive. Has anyone found a cheaper alternative.
What are you calling inexpensive? IMO $99 Stinger digital voltmeter is as cheep as the come. With that said. I wouldn't run the Stinger voltmeter I have had a few that have offer noise threw the system. Check out the Dakota Digital volt meters.
I have a volt meter front a center. I like to be able to see what voltage the batterys are at when playing from back of the boat or from another boat. I run the Xantrax Link 10. Its a Volt/Amp meter. http://www.wakeworld.com/MB/Discus/messages/65921/327807.html
