    I have 3 little voltage alarms that get connected to the balance lead of my batteries. I have a stand alone Capacity Controller that I have been using for a year or so. Then my I also have my digital 6-12 amp charger that also tells me individual cell voltage. I also have a nice snap-on tools/bluepoint digital multi meter. I did a little comparison with them on my batteries and found a big difference in results. The 4 cheapo voltage alarm/meters were almost .1 volt different (showing less than) from my digital snap-on meter or the built in meter on my charger.

    I am going to trust the built in and my snap-on meters. Is there a better, higher quality alarm that can be purchased rather than the 3 dollar units?
