KiloVault HLX+ Series

KiloVault® HLX+ Series™ Deep Cycle Lithium Batteries

The first battery for all climates!

The KiloVault™ HLX+ series of solar lithium batteries is the next line of heavy-duty deep cycle batteries for solar applications. The new HLX+ is the first solar lithium battery made for both hot and cold. This premium product offers the features of both the HLX and CHLX series of batteries, at an exceptional value. Key upgrades allow for ease of use and battery bank performance, and premium quality at the same competitive price of earlier models.

Designed with versatility in mind, the HLX+ serves as a drop-in replacement for lead-acid batteries in a renewable energy system, providing more energy and a higher cycle count with less weight. They also thrive in marine, RV, camper, golf cart, medical device, lighted signage, and off-grid applications. The HLX+ boasts some of the highest surge ratings in its class, perfect for kitchen appliances or large power tools.

Features

  • One battery that works in both hot and cold environments – even down to sub-freezing temperatures
  • 100Ah cells offer double the capacity of the prior version, providing increased power output and efficiency

  • Works in 12, 24 or 48V configurations
  • Even after discharging it completely 2000 times, 80% of the capacity remains
  • Maintenance-free – No watering required, or cleaning of hazardous chemicals
  • Smart investment – Lower cost per Watt-hour/cycle and longer lifespan than lead acid batteries
  • Safer – No thermal runaway issues as with other lithium technologies
  • ETL certified to UL Standard 1973
  • 7.5 year warranty

KiloVault HLX+ Product Details

The Safer Lithium Battery Technology

KiloVault’s LFP technology isn’t subject to the thermal runaway issues as with other lithium technologies. No active cooling needed.

Batteries with Depth

Hammer the battery with 100% discharge every day, like you mean it and even after 2000 cycles 80%+ of the battery’s energy capacity will be there for you. Discharge it less and the story gets even better.

Batteries that Don’t Need Babysitting

No regular watering required or wanted. No cleaning off of acid along the terminals. No dangerous off-gassing. No equalizing. No desulphating. Just wire them up and go about enjoying your life.

Higher Efficiency, Less Waste

You will get 8 to 14% more useable stored energy compared to lead acid batteries, thanks to higher efficiencies in the HLX series.

Smart Investment

Your cost per Watt-hour stored per cycle over the HLX+series’ lifetime will be less than lead acid batteries, reducing the headache of buying and changing out batteries every few years.

Integrated Bluetooth for Monitoring

Built-in Bluetooth and the convenient KiloVault HLX app make monitoring battery health and performance easy.

Provides an instant overview of your HLX+ batteries' state of charge, present power consumption, power harvest networking status, heating status, Bluetooth connection status, and more - at both the bank and individual battery level. Displays alerts and pushes them to the KiloVault iT app.

HLX+ Mounting Brackets

three deep cycle batteries of different sizes placed on their mounting brackets

Each bracket securely mounts a single HLX+ Series battery to a load bearing surface. Finished with durable black powder-coated paint that protects against rust and corrosion and is not affected by sun exposure.

KiloVault iT App

A Bluetooth app for iOS and Android phones that helps users troubleshoot HLX+ battery bank problems and view information about individual HLX+ batteries. The app can also be used to put HLX+ batteries into "storage mode" to reduce their self-discharge.

Available soon in English, Spanish, and French to the Apple and Google app stores.
