Despite a charger shutting off it still does not mean the battery was at 100% of charge just that the charger shut down at a predetermined "full charge". In a situation like this the charge parameters for "100%" need to be adjusted so that the monitor can re-set itself. Some chargers that don't do float will often shut down before you get to 2% acceptance. If the "charged" parameters are not set up well the monitor may never recalculate the CEF (charge efficiency factor). If my bank is accepting 4.8 amps it is not fully charged but at less than 2.4 amps going in it is much more accurate to approximate a full charge. This means there must be less than or equal to 2% amps in of your banks total capacity for a period of about 5 minutes or more for the Link 10 to consider it fully charged. The Link 10 for example ships with the charged parameters set at 2% of the bank which from the factory is a setting of 200ah. They can however be programmed to be smarter and work better with your bank.īank size can be programmed, charge volt parameters, the % of amps going in can be set so that the meter reads 100% at differnet % of amps in / bank size. They can't be adjusted or tuned in terms of actual measurement, as in, it's reading 12.25 volts and it should read 12.27 volts. Have other people had similar experiences with the amp-hour function?Īttached is a product discription of the Victron BMV-600. After a few days without a resetting charge, the amp-hour reading of a battery meter is pure fiction," p. Monitors have a microcomputer that tries to do this, but over time the inaccuracy accumulates. The rate of discharge needs to be taken into account. keeping track of amp-hours available is not as simple as offsetting amp-hours out against amp-hours in. In terms of amp-hours he writes: "what you should not put great faith in is the amp-hour function of a battery monitor. (2009), in writing about the importance of hardwired monitors, says that the voltmeter and ammeter functions are most valuable. although the Victron contains a voltmeter function, it appears that the monitor is geared toward the calculation of amp-hours.ĭon Casey, This Old Boat, 2nd ed. They appear to be well-liked - and they are cheaper. I took a look at the Victron website and other websites that sell the BMV-600. Thanks Tom and Treilley for the reference to Victron. Thanks as well for filling me in on that extra $150 needed for the wiring harness. Thanks Larry for the good review of the Xantrex Linklite. Shunt selection capability enables flexible system integration.Displays voltage, current, consumed amp hours and remaining battery capacity.Provides critical information about the status of your battery bank.Read your battery bank like a fuel gauge.It is equipped with an internal programmable alarm relay, to run a generator when needed or to turn off devices when the battery voltage exceeds programmable boundaries. A second battery input is also provided to monitor voltage on a second battery. Using a clear backlit LCD Display and an intuitive user interface, all parameters can be recalled with just a button press. The LinkLITE selectively displays voltage, charge and discharge current, consumed amp hours and remaining battery capacity. A new shunt selection feature enables the LinkLITE to measure currents up to 1,000Amps respectively. High performance measuring circuits, along with complex software algorithms, are used to exactly determine the remaining battery capacity. It is equipped with an internal programmable alarm relay, to run a generator when needed or to turn off devices when the battery voltage exceeds programmable boundaries.ĭefining the amount of energy available in a battery is a complex task since battery age, discharge current and temperature all influence the actual battery capacity. It selectively displays voltage, charge and discharge current, consumed amp hours and remaining battery capacity. The LinkLITE battery monitor can measure currents up to 1,000Amps. I'm interested in using it to monitor the charge on a 225 ah bank of 6v Trojan T-105 batteries. Just wondering if anyone has had any experience with the xantrex linklite.
