User Manual

Thank you for choosing the Spintec Battery Manager!
Please read this manual before using the device.
How to discharge a battery
1. Place your battery in a cool place out of direct sunlight.
2. When discharging a pack that is still in your car, make sure the Battery Manager is not touching
any electrical parts or parts that may melt when hot. Be careful with graphite chassis as it conducts
electricity.
3. Connect the red wire to the positive (+) terminal of your pack.
4. Connect the black wire to the negative (-) terminal of your pack.
5. The Battery Manager will now check your pack and will start discharging automatically. The Pack
Information Display (PID) will show the status of the discharge process.
6. When the pack is discharged, the PID will tell so. You can now read out the results.
7. Disconnect the Battery Manager from the pack.
To read out the data of the previous cycle
1. Connect your Battery Manager to a pack.
2. The display will now show the data.
3. To keep this data in memory, disconnect the device from the battery before countdown (3-2-1)
begins. By doing this, you can read out the data as often as you like.
To read out firmware version and data of the best pack ever
1. Connect your Battery Manager to a pack.
2. When the text 'Welcome to Spintec' is scrolling, disconnect the Battery Manager.
3. Repeat steps 1 and 2.
4. Now when you connect the Battery Manager, you enter the 'Special Function'.
5. Read out the firmware number and best pack data.
6. The next time you connect, the device operates normally again.

Warnings
1. This device is designed only to be used on RC racing rechargeable NiCd or NiMH battery packs
consisting of 6 cells (7.2 V) or 7 cells (8.4 V) which are capable of delivering currents in excess of
35 Amps. Using the device on other batteries can result in damage of the device or the pack.
2. The device can become EXTREMELY HOT during use. Do not touch the device unless you are
sure it is cool. Handle the device on the wires to be sure.
3. Do not use the device in direct sunlight. When using it place it in a cool spot in the shadow.
Otherwise the device may become too hot which can result in damage.
4. Do not place the device on plastic or other surfaces that may melt or burn while using it.
5. This device is not intended to be used by children under the age of 14 years.
6. Spintec guarantees the device to be operating in normal order. Spintec is not responsible for any
damage caused by altering, opening of the device or using it not according to instructions.

The Battery Manager: more power and longer battery life!
High discharge current
In a race batteries are discharged with a current well above 30 amps. If your discharger uses a
low current, your packs will get used to this and loose their voltage ('punch'). All the 'cell
equalizing' discharge trays available are low-current devices. They are restricted by technical
limitations as a consequence of discharging each cell individually.
Cool batteries
The Coolflex technology (a block of 35 amps followed by a cooling-down period) prevents heat
build up during the discharge process. Why should you kill your batteries during maintenance?
Accurate measurements
The Battery Manager is equipped with a microprocessor that constantly monitors the system.
Unlike other dischargers, it precisely measures the current and voltage. Based on this information,
the optimum cut-off point is calculated.
Information display
What good is a discharger if it doesn't tell you how much has been discharged? You like to know
how much longer you could have raced on your pack. The Battery Manager gives you the exact
data. Not only runtime, but also average voltage, capacity, energy and internal resistance. It even
remembers the data of your last pack, just like it holds the data of your best pack ever discharged.
A clever cycle counter keeps track of how often you race.
Small size, easy to use
No external power supply to be connected, no hassle with plugs and mains. Just connect the
Battery Manager and the rest is easy.
TIPS:
During discharge you will here a clicking sound coming from your batteries. This is the active
decrystallization process of the Coolflex technology at work!
Discharging a fully charged battery can take more than two hours due to the Coolflex technology.
This is the only way your batteries have enough time to dissipate all the energy and prevent heat
build up. Remember: the actual discharge current is 35 Amps!
Displayed runtime is calculated to be equivalent to a conventional constant 35A discharge. This is
approximately the time you could have raced on what was left in the pack, depending on
circumstances.
Never use low-current discharge devices to discharge your pack.
Always immediately stop racing when your battery goes flat. If you keep racing too long, you might
damage your battery.
After racing, connect the Battery Manager as soon as possible to the battery. This will give best
results for the pack.
Trick: discharge your battery again just before charging it. Top racers use this, the pack will accept
more energy when doing this!
Good luck with racing!
