This 10.8V 5Ah pack uses Samsung 21700 50E cells in a 3S1P configuration, delivering a nominal energy of 54Wh with exceptionally low internal resistance. The integrated protection board provides 3A continuous current support, over-current cutoff, over-charge/discharge protection, and short-circuit safety. Blue PVC housing resists abrasion and provides dielectric strength, while the 153 mm 22 AWG output leads maintain minimal voltage drop. Pre-charged to 50%, it’s ready for immediate use in handheld tools, portable medical devices, or IoT gateways.
