KiloVault 12V Cold-Rated Lithium Ferro Phosphate (LFP) Deep Cycle Battery (CHLX 1800)
CHLX Series lithium-ion solar batteries are designed and tested to thrive under the sometimes rigorous conditions off-grid or hybrid inverters and battery chargers can place on deep cycle solar batteries. This battery has a 1.8kWh capacity; 3.6 kWh capacity and 1.2 kWh capacity versions are also available.
The 12V, 1.8 kWh CHLX battery's LiFePO4 (lithium ferro phosphate) cells are highly efficient, maintenance-free, safe, and will last an impressive 2,000 cycles cycling to a full 100% depth of discharge (or 5,000 cycles when cycling to 80% DoD).
Up to 4 CHLX batteries can be used in series to create systems of 12V, 24V, 36V, or 48V, or you can use up to 4 CHLX batteries in parallel for a higher capacity 12V bank. All parallel strings must be maintained within 0.2V of each other.
Automatically Keeps Your Batteries Warm in Winter
Unlike other deep-cycle lithium batteries, CHLX batteries are rated to work in ambient temperatures as low as -22°F (-30°C). While in these sub-freezing conditions, a CHLX battery utilizes charging current to activate an internal heating film to warm its temperature to above freezing, then proceeds with normal solar charging.
KiloVault CHLX 1800 Cold-Rated Lithium-Ion Battery Features
- Can be configured for 24V, 36V, or 48V systems by using two, three, or four batteries in series
- Note: A maximum of 4 CHLX batteries can be used in series or in parallel, but not both
- Can be discharged to its full rated capacity of 1,800 Watt-hours (100% depth of discharge)
- Even after discharging to 100% 2,000 times (or discharging to 80% 5,000 times), 80% of the 1.8 kWh capacity remains
- Maintenance-free – no watering, cleaning, or hazardous chemicals
- Can be used in ambient (external) temperatures from -22°F (-30°C) to 113°F (45°C)
- Cold-rated LFP battery for sub-freezing temperatures - When the ambient temperature is below 32°F (0°C), charging current flows to an internal 96W heater to warm up the battery. The battery can start discharging when its internal temperature reaches -4°F (-20°C) and can start charging when its internal temperature reaches 32°F (0°C)
- The heater activates at an external temperature of 32°F (0°C) and stops when the battery reaches an internal temperature of 50°F (10°C) - however, the battery continues heating even after reaching low temp protection release of 39°F (4°C)
- When the batteries are on an AC charger, warming the battery's internal temperature from -22°F (-30°C) to 50°F (10°C) takes about 2 hours
- Warming the battery's internal temperature from -4°F (-20°C) to 50°F (10°C) takes about 1.5 hours
- When the batteries are charging with solar - depending upon the charger output - heating may take longer
- Below -22°F (-30°C), the heat dissipation is too great to bring the battery up to operating temperature
- Higher efficiency and lower cost per Watt-hour than lead acid batteries
- Lithium ferro phosphate cell chemistry (LiFePO4) is safer than other lithium-ion technologies and has no hazardous chemicals or thermal runaway problems
- Takes up to 150A of continuous charging/discharging current, meeting the tough demands of serious inverters and chargers
- Built-in Bluetooth and the KiloVault HLX app combine to provide battery health and performance monitoring
- 7.5-year warranty
IMPORTANT - PLEASE READ BEFORE COMMISSIONING YOUR SYSTEM
- EACH CHLX battery must be 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 bank.
- 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.
- 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-amperage chargers). Going any higher risks one or more batteries automatically shutting off from high-voltage protection.
- Similarly, the inverter's low voltage cutoff should be set 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 from low-voltage protection.
- 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 CHLX's battery management system (BMS) has special circuitry to detect short circuits and protect itself. Many brands of inverters, charge controllers, and battery monitors will present a brief but high surge that the BMS may interpret as a short. The CHLX can handle one of these perceived 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.
- Be sure to tighten the battery terminals before operating. Failure to do so will lead to the terminals overheating, melting the case, and potentially causing a fire.
- It is VERY important to give your new CHLX batteries a full charge as soon as you unbox them, even if you're not going to commission them right away.
