The IDX E-HL9S is a lithium ion, V-Mount battery. It offers 88Wh for 14.4VDC equipment in a compact package. 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. Battery circuit protection ensures the E-HL9S is fully protected against common causes of battery misuse, guarding against over charge, over discharge, over current and exposure to high temperatures.
