*NOTE: Charging rates below the battery's maximum capacity will extend battery life. A charge rate of 100A is recommended, though up to 150A is allowed. After 3000 cycles at 100% depth-of-discharge the battery's capacity will be approximately 75% of when it was new.
**NOTE: altE strongly recommends staying within a temperature range 32 - 113°F (0 - 45°C) for both charging and discharging to prevent damage and extend battery life.
IMPORTANT - PLEASE READ FIRST - BEFORE COMMISSIONING YOUR SYSTEM!
1) Each battery must be individually charged to 14.0V before placing it into operation with other batteries. Otherwise, the batteries will independently hit ‘full’ or ‘empty’ and shut off before others in the same battery bank.
2) Equalization charge must be turned off in your solar charge controller or AC charger. If left on, the equalization charge will raise the voltage too high, damage the batteries and void the warranty.
3) Bulk/Absorption charge voltage should be set to no higher than 14.0V for a 12V system, 28.0V for 24V system, and 56.0V for a 48V system (and lower for high amp chargers). Going any higher risks one or more batteries automatically shutting off in a high voltage protection mode.
4) Similarly, the ‘Low Voltage Cut-Off’ on the inverter should be set for no lower than 12.0V, 24.0V and 48.0V for a 12V, 24V and 48V system, respectively. Going any lower risks one or more batteries automatically shutting off in a low voltage protection mode.
5) When turning on breakers to inverters, charge controllers, battery monitors, etc. connected to the batteries wait 45-60 seconds between powering up each device. The KiloVault’s battery management system has special circuitry to detect short circuits and protect itself. Many brands of inverters, charge controllers and battery monitors will present a very high but very brief surge that can be interpreted as a short. The KiloVault can handle one of these ‘shorts’ every 45-60 seconds.
Alternatively, in most circumstances all devices can be powered up at once but the batteries will go into auto-protect mode and turn off for 30-60 seconds but then restart normally.
6) Be sure to tighten the battery terminals before operating. Failure to do so will lead to the terminals overheating, melting the case and potentially cause a fire.
altE Tips and FAQ - KiloVault Battery:
Is it good to insulate the KiloVault battery ?
It's the same with any type of battery. Because batteries heat up when they charge, if you insulate the box they are in, it will retain the heat better and the batteries will stay warmer. But make sure to remove the insulation in the hot months, as overheated batteries will have a shorter life.
What is the best operating and storage temperature for the KiloVault?
The optimal temperature range overall is 59 – 95°F (15 – 35°C). Full operating temperatures must be greater than 32°F (O°C) and less than 133°F (45°C). Charging the battery below 32°F (0°C) will potentially damage it.
What are the recommended charge controller/inverter settings?
We highly recommend setting the Bulk/Absorb voltage to *14.0V* for a 12V system (*28.0V* for 24V system, *56.0V* for 48V), float voltage of 13.8V (27.6V for 24V, 55.2V for 48V). Higher settings will reduce the *life* of the batteries. For the inverter low voltage cut-off we strongly recommend 12.0V *or higher* (24.0V, for 24V systems, 48.0V for 48V systems). Limit the duration of the absorb voltage period to 2 minutes if the charger is more than 100A, otherwise set to 5 minutes.
Are there any considerations when wiring the batteries in parallel?
Yes - the maximum configuration is 4 parallel strings of 4 series batteries (16). In addition, when adding another parallel row of batteries to an existing one, it is important to maintain all parallel series strings within 0.2V of each other. Before adding a new row of batteries to an existing one, charge all batteries to 100% first.
Can I mix and match models or brands?
No - this is not good practice with any battery bank.
Should I do an equalization charge on the batteries?
No- much like AGM batteries, an equalization charge could damage them by overcharging them.
Are the batteries shipped fully charged, or do I need to charge them?
No - shipping guidelines do not allow deep cycle batteries to be fully charged during shipment. **Before you put the batteries into operation they must ALL be charged to exactly the same voltage (choose a voltage between 14.0-14.4,V but make sure they are *ALL* the same). This will ensure you start with an even charge across the battery bank.
Can I do a constant trickle charge on the batteries?
Storing the batteries with a constant small trickle charge is not recommended. Unlike lead-acid batteries, lithium iron phosphate batteries self-consumes energy at such a low rate (0.020 amps or about 6 Watt-hours/day), the battery can be easily over-charged if put on a trickle charger. Over-charging the battery triggers the over-charge protection - shutting it down until the voltage goes down enough by itself. Once that happens the trickle charger would quickly raise the voltage up too high once again. As a result, the constant cycling of this circuitry will shorten the life of the entire battery.
Is it bad to overcharge or over-discharge the battery?
Yes, this will decrease the life of the battery. It’s recommend to never discharge or charge the battery to the point where it has to shutdown to protect itself.
