IDX E-HL9 88Wh Li-ion High Load Battery with V-Mount, PowerLink & Digi-View With a continuous draw of up to 10 Amps, the E-HL9 has an impressive capacity using highly durable cell technology High-load capacity results in 50% higher discharge rate for this series. Advanced low temperature discharge characteristics prohibit a voltage drop off down to -4 degrees Fahrenheit in extreme environment conditions. Longer overall lifecycle-operators can expect about 10% longer battery viability when the 500-cycle level is reached. PowerLink technology allows two E-HL9 batteries to be docked together, doubling capacity up to 176Wh for longer run times and high power needs.
