Romeo Power Designs 48V Lithium Forklift Battery

Exclusively for Komatsu USA; Sold with Compatible Power Designers Sibex REVOLUTION Charger

VERNON, CA – September 26, 2018 /PRNewswire/ – Romeo Power, the energy storage technology company founded by engineers from SpaceX, Tesla, and Samsung, today announced their 48V Thunder Maxx lithium forklift battery to be sold through Komatsu USA’s nationwide chain of factory stores. The Romeo Power Thunder Maxx delivers 3.2x the total energy throughput of the leading lead-acid forklift battery and lasts about 3.2x longer, ~4,000 charges. It’s the first in a full line of Thunder battery packs designed as drop-in replacements for the lead-acid batteries in electric forklifts for more efficient fleets.

“Komatsu has evaluated the Thunder Maxx product thoroughly and committed to purchase,” said Romeo Power CEO Mike Patterson. “This pack was designed specifically for 48V Komatsu forklifts with 24-85-21 trays, and we have the engineering capability to custom design a lithium battery pack for any customer or application.”

Thunder Maxx comes with a 6-year warranty, charges in as little as 2.5 hours, and eliminates battery swaps with opportunity charging. It goes in once and never leaves the forklift so fleet owners can replace three lead-acid batteries with one Thunder Maxx and reclaim lost productivity with less equipment – no stopping three times per day to swap out traditional lead-acid batteries.

  • Thunder 48V, a capacity upgrade for a 24-85-21 (or similar) to provide maximum energy in a tray
  • Maximum energy packaging using our BR-E energy module for maximum run time
  • Integrated junction box with pack-level BMS for simplicity in design and safety
  • Vented cover for improved cooling
  • Clean, high-efficiency upgrade for lead-acid batteries
  • Solutions also available for 24-85-17 trays with same modules

Less equipment also frees up valuable warehouse space by eliminating the need for a dedicated battery room. Also, unlike lead-acid batteries, Thunder Maxx produces zero emissions and requires zero maintenance: no hazardous watering or time-consuming equalize charging and the end of toxic dust, fumes, and spills.

Thunder Maxx lithium packs are charged exclusively with Power Designers Sibex’s REVOLUTION high frequency, modular battery chargers that deliver peak efficiency greater than 93%, and efficiencies greater than 90% throughout the entire charge cycle.

“Power Designers Sibex and Romeo Power offer a lithium battery and charger integrated total solution package that satisfies existing forklift configurations,” said Dan Crowley, Senior Vice President of Power Designers Sibex. “Our solution is fully plug and play, it offers an efficient and productive power alternative with extended run times and excellent charging capabilities designed specifically for the ruggedness of the material handling market.”

Electric Forklifts Are Huge Market for Lithium Batteries
North American forklift sales set a record in 2017 at more than a quarter million units, with electric forklifts accounting for 64% of that, according to a 2018 article by Material Handling & Logistics. E-commerce is a big reason for overall forklift industry growth – e-tailers have warehouses filled with all kinds of goods that need to be handled fast and efficiently.

In addition to increased productivity thanks to greater efficiency and maneuverability, the growing popularity of electric forklifts specifically is due in large part by a desire for reduced emissions in the work environment, according to MHI, the largest material handling, logistics, and supply chain association in the US. It makes sense to power electric forklifts with lithium vs. lead-acid batteries, which emit toxic hydrogen sulfide gas and risk sulfuric acid spills.

“Pairing the Romeo Power Thunder Maxx with Power Designers Sibex REVOLUTION chargers gives our customers a very easy, operator-friendly experience,” said Terry Rose, GM for Komatsu Forklift North America Retail Operations. “The Thunder Maxx is an optimal fuel source without the lead-acid issues: safety/hazmat concerns, battery equalizing and watering, and battery replacement. Our customers can dramatically improve efficiencies with run times of more than two shifts on a single charge, and many of our long-term customers have converted from lead-acid and propane and lowered their overall operating costs.”
