This is a a light weight safe LiFePO4 battery pack.  LiFePO4 provides about 30% more power @ half the weight!  This batter only weighs 5lbs 9oz.  Review the datasheet for dimensions. 

We have been using these batteries in our custom robots for some time now.  They are much safer than LiIon batteries, are lighter than lead acid, and offer excellent charge and discharge cycles.   The batteries have internal circuit boards that protect the batteries, provide a charging circuit, and equalize the cells.  You can use standard 24V battery charger on them and the automatic built in circuit of the battery will shut the charging down when its fully charged.  We also carry LiFePO4 chargers that will ensure the battery reaches its peak voltage (which is slightly higher than lead acid).

Review the datasheet for full details.

Review the MSDS.
