Manual
Example:
In the normal case, a pack with four parallel and four series-connected cells (4s4p) has a lower voltage than the
outer ones, since they become warmer during operation and thus have a higher self-discharge. After a few cycles, the diffe-
rence is perhaps only 0.02 or 0.05 volts, but after 30 cycles one may already observe differences of 0.2 volts, depending on
the cell and discharge depth.
If this pack is now charged with a voltage difference of 0.2 Volt, the charger will charge as before also up to 16.8 Volt total
voltage. However, this voltage will no longer be evenly distributed among the four groups connected in series. The cells are
now loaded, for example, as follows: Group 1 - 4.3 volts, Group 2 + 3 - 3.1 volts, Group 4 - 4.3 volts
The cells with 4.3 volts charged cells age very fast, which is not immediately noticeable until the next flight.
In the unloading cycle, the individual groups are now unloaded accordingly. While the outer cells are e.g. Still have a charge
of 3.6 volts, the inner cells lie at approximately deep discharged 2.4 volts.
With an LiPo balancer, this misconduct can be circumvented by balancing the cells of the pack
(Lifetime is thereby extended). In addition, the user is informed of the state of each cell during each charging process, as a
result of which expensive measurements are omitted.
Warranty
The statutory warranty covers manufacturing and material defects in normal use. We do not accept liability for consequenti-
al damages!The guarantee / warranty does not include.
• Damage caused by failure to observe the safety instructions or the operating instructions
• Force majeure, boggling, incorrect handling
• Overuse or foreign influence
• Unauthorized changes
• Damage caused by loss of control
• Influence of current, high voltage or lightning strike
• Normal wear and tear
• Visual defects
• Transport, shipping or insurance costs

Care and Maintenance:

• Although the model is a highly complex system, maintenance is limited to just a few points.
• After every flight, check the model for visible damage and replace any defective parts immediately. This is especially true
for rotating parts.
• To minimize the wear of moving parts, they must be regularly cleaned and lubricated.
• Although the bearings are relatively insensitive to soiling, they must nevertheless be regularly checked and, if necessary,
cleaned or replaced.
• Silicone-free silicone oil is recommended for gears and open-running bearings, as is also used for the lubrication of
open-running chains. This will dry out after a few minutes, so no dirt or dust can stick to the freshly lubricated compo-
nents.
• Before disassembling parts, it is advisable to take one or more photos (also from other viewpoints). This allows you to
focus on any pro-blems that may occur.
