WARNING:

: :

DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with

GE864-QUAD Automotive V2. Their use can lead to overvoltage on the GE864-

QUAD Automotive V2 and damage it. USE ONLY Li-Ion battery types.

• A Bypass low ESR capacitor of adequate capacity must be provided in order to

cut the current absorption peaks, a 100µF tantalum capacitor is usually suited.

• Make sure the low ESR capacitor (usually a tantalum one) is rated at least 10V.

• A protection diode should be inserted close to the power input, in order to save

the GE864-QUAD Automotive V2 from power polarity inversion. Otherwise the

battery connector should be done in a way to avoid polarity inversions when

connecting the battery.

• The battery capacity must be at least 500mAh in order to withstand the current

peaks of 2A; the suggested capacity is from 500mAh to 1000mAh.
