The LiFT Pack M36 is a 36V lithium-ion battery for use with narrow aisle forklifts.
One of the most important benefits of Flux Power’s choice of lithium is the dramatic increase in energy density over current lead-acid battery solutions. Flux Power uses Lithium-Iron-Phosphate (LiFePO4) which has a specific energy of ~110 watt-hours per kilogram, compared to lead-acids ~40 watt-hours per kilogram. What does this mean? Our batteries can be ~1/3 the weight for similar amp-hour ratings.
Flux Power lithium batteries are fast. They can be fast charged completely and can handle ultra-fast charging up to 1C (a full charge in 1 hour). Lead-acid can only be fast-charged up to 80% after which charging current drops dramatically.
In addition, Flux Power batteries maintain excellent performance under discharge rates as high as 3C continuous (full discharge in 1/3 an hour) or 5C pulsed. Lead-acid experiences dramatic voltage sag and capacity reduction by comparison. In fact, the discharge profile of a Flux Power lithium battery shows how voltage and power remain almost constant throughout its discharge, unlike lead-acid. This means that even when the battery runs low, performance stays high.
Our batteries perform better when charged during breaks in the day. Running Flux Power lithium-ion batteries using ‘opportunity charging’ can actually
Our batteries exhibit no ‘memory effect’ associated with opportunity charging, so discharge and charge the battery at any point without consequence. With lead-acid, failure to fully charge leads to sulfation which damages the batteries. This also occurs when storing lead-acid while not fully charged. With Flux Power lithium-ion, store the battery at any state of charge except near zero.
Finally, Flux Power lithium is ~95% energy efficient, compared to the ~80% efficiency for
