Thank you for choosing the Spintec Battery Manager
v2!
Please read this manual before using the device.
How to change settings
If you press the switch for a short time, the arrow will go to the next menu item. To change or select
that item, press the switch for a longer time.
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. Verify the discharge settings. Make sure you have selected the right number of cells and the
desired cut-off voltage.
6. Select ‘Start’ and hold the switch.
7. When the pack is discharged, the display will show ‘Done’ and the backlight will be blinking
on/off. You can now read out the results.
8. Disconnect the Battery Manager from the pack.

Warnings
– This device is designed only to be used on RC racing rechargeable NiCd or NiMH battery
packs consisting of 4 to 8 cells (4.8 to 9.6 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.
– 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.
– 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.
– Do not place the device on plastic or other surfaces that may melt or burn while using it.
– This device is not intended to be used by children under the age of 14 years.
– 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!
Settings
– Use the 35 Amp setting for high-capacity racing cells, like GP3300/3700/4300 and
IB3600/3800/4200.
– Use the 10 Amp setting for lower capacity cells, like Micro 1/18 packs and receiver/transmitter
packs.
– For almost any pack we recommend to use the 0.9 V cut-off setting. However for the IB4200
cells we highly advise to use 1.0 V, as these cells do not like to be discharged deeply.
– Discharge modes.
CC
: Constant Current. The load on the pack remains the same during the complete discharge.
This is the default and most accurate setting, good for most circumstances.
CV
: Constant Voltage. When the voltage reaches the cut-off voltage, load on the pack is
reduced to get maximum energy from the pack. Very good to revive old cells. There are 4 CV
steps, you can disconnect the unit at any time during this stage, indicated on the display.
CP
: Constant Power. When the voltage drops, load on the pack is increased. This will give you
the quickest discharge possible. Use this for example when cycling fully charged packs.
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? 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').
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 hear 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 four 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
(10A when in 10A mode). 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 do this, the pack will
accept more energy when doing this!
Good luck with racing!
