Batteries and Charging
Battery Type
The DX System is designed to perform optimally with either Lead-Acid or Gel
Cell 24 V deep cycle batteries, rated at 20 - 120 Amp hours. The maximum
average discharge rate must not exceed half the rated capacity, in Amp hours.
High continuous discharge rates dramatically reduces the available battery
capacity. For example, at a discharge rate equal to the rated capacity, the
available capacity is 50 - 60 %. At a discharge rate of half the rated capacity,
the available capacity is 70 - 80 %..
A wheelchair that draws maximum average battery current of 20 A, requires
a battery of at least 40 Amp hours. A battery of only 20 Amp-hours, would
begin to suffer a drop in performance at about half of its available capacity.
The 40 Amp hour battery would have a full performance range of 4.5 times
greater than the 20 Amp hour battery; a 80 Amp hour battery would only
increase this range by 2.5 when compared to a 40 Amp hour battery.
Battery Charging
The battery charger socket is a 3 pin XLR type with pin configuration as
shown below. Ensure that the charger used is compatible with this pin out
before connection.
Note :
The inhibit is shorted to B- on the Battery Charger plug.
