Lithium-Ion Technology VS Lead-Acid Battery

The high-performance Li-Ion technology is especially suitable in cases where lead-acid batteries are in use and have to be changed in two to three-shift operation.
Lithium-ion batteries do not need to be replaced. By quick interim charging any downtime, such as a lunch break, can be efficiently used and the battery is recharged in a very short period of time. Interim charging does not affect the battery service life.
Lithium-ion technology supplies constant voltage throughout the entire application time. Accordingly, you can work under full power through several shifts without having to change a battery or do any kind of maintenance at all.

Longer battery Life time

2500 full charging cycles with at least 80 % residual capacity
Afterward: Several thousand full charging cycles still possible
Combined with higher battery efficiency an altogether higher usable battery capacity

Emission-Free Battery

No evolving battery gases (hydrogen) and acid

Does not contain toxic substances like Cd, Pb or Hg

No battery change necessary for most 2-shift applications

Cost & time savings

No need for a battery change and charging room

No battery-maintenance needed

No water-refilling, battery cleanup, etc.

No need for electrolyte circulation


Higher Efficiency Compared To Lead-Acid

Self-monitoring via the autonomous battery management system
Safety functions on cell-, module, and battery level
Safe control of the truck in any battery status
Integrated shock sensor
Up to 30 % higher electrical efficiency
Fewer energy losses
Less heat development inside the battery
Full usability down to 5 % State of Charge (SoC)

Perfect Performance In Cold Area

Battery Pack Heating Management
BSLBATT battery pack with heating management during the discharge process, the temperature rises from - 20℃ to 0℃ only takes 25-30 minutes.
General battery pack during the discharge process, the temperature rises from - 20℃ to 0℃ will take 85-90 minutes.
