The E-HL9S is a high quality battery pack which delivers the same capacity and high draw specification as the E-HL9.

The E-HL9 and E-HL9S are designed to operate in
all conditions, but they excel when used in cold
weather temperatures. Even in temperatures down
to -20°C, the E-HL9 and E-HL9S can be used without
experiencing the sharp voltage drop-off that affects
many other battery models in this environment.

The E-HL9S is built for those users who do not require PowerLink, BMS or Digi-View functionality.
