To calculate the total amp-hours for your six 6V lead-acid batteries using the Xantrex Link 10 monitor:

1. Determine Battery Configuration:
- If the six batteries are connected in series, their voltages add up, but the amp-hour (Ah) capacity remains the same as a single battery.
- If the six batteries are connected in parallel, their amp-hour capacities add up, but the voltage remains the same as a single battery.
- If the batteries are in a series-parallel configuration, calculate accordingly.

2. Identify Individual Battery Capacity:
- Check the amp-hour rating of a single 6V battery (e.g., 200Ah).

3. Calculate Total Capacity:
- Series connection: Capacity remains the same as a single battery (e.g., 200Ah).
- Parallel connection: Multiply the amp-hour rating of a single battery by the number of parallel batteries (e.g., 3 batteries in parallel, each 200Ah → 600Ah total).
- Series-Parallel connection: Multiply the amp-hour rating of one series string by the number of parallel strings.

4. Set the Link 10 Monitor:
- Enter the total amp-hour capacity into the Link 10 as described in the manual to ensure accurate monitoring.

  • Page 7: Introduction

    If you wish the Link 10 to support an external Low Battery Alarm, such as a bell or buzzer, or if you need the Link 10 to report data to a computer or data logging unit, these options must be included at the time of manufac- ture and cannot be retrofitted in the field.

  • Page 8: Battery Basics

    Batteries can be ruined by excessive discharge. They may also be dam- aged by under-charging. A battery (or bank of batteries) may be storing less energy than you think. The Link 10 provides all the key data you, or your technician, need to make decisions about battery use and charging.

  • Page 9: Installation

    Basic installation of the Link 10 on a 12 or 24 volt system involves only five wires. Because the Link 10 will work on systems up to 500 volts, special high voltage installation techniques are discussed beginning on page 44. You need to read this section if you're working on an electric vehicle or system where more than 50 volts is encountered.
  • Page 10 Link 10 should pro- vide an adequate seal against moisture. If a sealant is used be sure it is silicone so that the Link 10 may be removed without damage. CAUTION! Orient ring so the ratchet teeth will engage properly.

  • Page 19 The LED bar graph display shows how much of your battery has been con- sumed. If you do not set your battery capacity correctly, your bar graph will not give you an accurate indication of battery state-of-charge. The Link 10 also uses declared capacity to calculate the Time Remaining, the charged current for Charge Efficiency Factor calculations, and other control functions.

  • Page 21: Setting Battery Capacity

    Setting Battery Capacity The first time you use the Link 10, it assumes you have 200 amp-hour lead acid batteries. If your battery capacity is different you must change the declared battery capacity. Follow these instructions to declare a new capacity: Press and hold the SET button for three seconds to enter SETUP (and Advanced Functions) menu.
  • Page 22 The Charged Parameters The Link 10 depends on the Charged Parameters to stay in sync with the battery state-of-charge, to automatically reset to zero, and to automatically calculate the CEF. The default settings are for 12 V lead acid (liquid or gelled) batteries.
  • Page 23 Charged Parameters & CEF If you change the Charged Parameters please use the following rules: The Charged Voltage Parameter MUST BE AT LEAST 0.1V BELOW the voltage at which the charging system finishes charging. Example: If your charging system finishes the battery at 13.8 volts, a Charged Voltage Parameter of 14.0 volts will not work.
  • Page 24 Setting Up Five different displays are available in the Time function. You may select present consumption level, a 4-minute average, a 16-minute, or a 32-minute average, or display the percent of rate compensated capacity remaining. Which method is best for you depends on your installation. Most installations will find four-minute averaging appropriate.

  • Page 26: Setting Peukert's Exponent

    Puekert's Exponent Peukert's Exponent is a number which describes how battery capacity shrinks as the rate of discharge is increased. The Link 10 uses a number between 1.00 and 1.50 to describe how fast a particular battery will "shrink" when a heavy load is connected. A more complete technical discussion of the Peukert Exponent, and typical value tables is included on pages 39–41.

    Making two discharge tests, one at a high discharge rate and one at a low rate, that bracket your normal range of operation, allows you to calculate an "n" that will describe this varying effect. The Link 10 uses an "n" equal to 1.25, which is typical for many batteries.

It may also be used to estimate the exponent "n" for a battery after a single discharge test.

    Electric Vehicles (EVs) The Link 10 is the ideal energy meter for EV instrumentation. It not only provides volts, amps, amp hours and time remaining, it adds two important bonuses: kilowatt hours and optional serial computer output. If you design or work with electric vehicles or battery-powered equipment of any type, you should realize that kilowatt hours are a more accurate measure of energy used than are amp hours.
