FEATURES
• Designed to fast charge/discharge 1~25 cell Nickel Cadmium
(NiCd) & Nickel Metal Hydride (Ni-MH) packs, and to charge
only 1~6 cell (2~12volt) Lead Acid (Pb) batteries.
• Uses either 12volt Lead Acid battery or 10~15volt DC power
supply input (Not supplied).
•The most outstanding feature of the SuperNova 250S is
its 10 intelligent battery memories, numbered 0 to 9.
These enable individual cell or pack parameters to be
memorised and stored, i.e. battery type, number of cells,
battery capacity, charge current and discharge current.
As a result of this, up to 10 different battery packs can have
their individual charge/discharge requirements set.
NOTE: The SuperNova is supplied with the 10 memories
already programmed. Unless these programs exactly match
your requirements, it will be necessary to modify them to suit
the battery packs being charged. How to carry this out
is detailed under Setting Battery Parameters.
•To protect both the charger and batteries, the maximum
charge and discharge currents are automatically limited.
• When discharging battery packs, the discharge cut off
voltage level is set at 0.9 volt per cell to avoid damage to
the battery being discharged.
• Zero Current Voltage Check prevents incorrect delta peak
auto cut-off caused by high connection resistance or high
resistance/old/faulty battery packs.
• Low and over voltage input battery warning function-input
voltages outside the range 9.5 to 15.5 volts causes a warning
message ‘Input Power’ to be shown on the display, together
with an audible warning.
• Automatic initial charge stage checks the condition of
the battery being charged. If the battery is not in a condition
suitable for charging, the display shows a warning message
‘Output Battery Connector Error’ along with an audible
warning.
• In the event of the battery being charged becoming
disconnected from the charger the display shows a warning
message ‘Output Battery Connector Error’ along with an
audible warning.
• Reverse polarity protection. The display will show ‘Output
Battery Reverse Polarity’ if the battery being charged is
connected in reverse along with an audible warning.
SuperNova 250S Charger
Dear Customer
Thank you for purchasing the highly advanced, low cost, easy-to-use Ripmax Pro-Peak SuperNova charger. To obtain
maximum performance from your new charger, please carefully read the following instruction manual.
The SuperNova 250S is an innovative multi-function charger far superior to existing conventional chargers. This unit is
especially designed to maximize charge efficiency using SJ’s own unique algorithm. The integral 2 line, 16 character LCD screen
displays various information relating to the operating modes and adjustment parameters, as well as key functions such as
battery charge state, which shows the percentage of capacity remaining. Furthermore, the SuperNova 250S is very user friendly,
even for beginners, thanks to its 10 intelligent selectable ‘battery parameter’ memories. The 10 memories, containing factory
pre-set battery parameters, can be re-programmed to store your own standard battery pack parameters so that you can obtain
the same precise results whenever you charge.
