Introduction

The RED CHARGER intelligent Lithium ion battery charger has been specically designed for fast and reliable charging of

RED BRICK V-lock batteries. The charger is capable of delivering 4.8 Amperes in constant current mode making them particularly

suitabletouserswhorequireafastturnaroundfromtheirbatteries.Externaldimensionshavebeenkeptascompactaspossiblefor

maximumportability.

Battery charging and performance features

Initially, the charger will only apply a pre-charge current of a few milli-amperes to batteries that are heavily discharged. Once the

cellsinsidethebatteriesreachasafelevel,thefull(maximum)chargingcurrentisdelivereduntilthebatteryreachesalmost80%state

of charge. After this, a constant voltage phase begins with the charging current decaying slowly until cut-off.
