Improper use of the battery is very dangerous. The battery must be handled carefully. 
Incorrect  wiring  or  short-circuiting  of  wiring  may  cause  fire  or  fumes.  Before 
connecting  or  disconnecting  the  battery  to  or  from  the  speed  controller  (ESC),  be 
sure  to  turn  o

  the  power  switch  of  the  ESC.  When  the  battery  is  not  in  use, 

disconnect it from the ESC or charger, and store it in a suitable location free of any 
loose wires or screws.

Incorrect wiring may cause fire or fumes that can damage both the ESC and 
battery beyond repair.

The surface of the body can be extremely hot after heavy load driving. Please 
handle the unit carefully after operation to avoid risk of burn.

Do not modify the ESC in any way. Use it only for its intended purpose. Keep the 
ESC away from flames or seat. Avoid splashing any liquid, such as water, on the 
ESC.

Thank you for choosing XARVIS XX. This product is a high-performance speed 
controller for drivers seeking the top end. Please read this instruction manual 
carefully before using this product, and use it correctly and safely. Please keep it 
carefully after reading.

Please check our website and official Twitter for details on the features and the 
latest information. (@ACUVANCE_JAPAN)

This new ESC is equipped with a high-performance MOSFET of the industry's 

highest peak
(currently when this product was released / according to our research).

As a result, output performance such as torque and efficiency has been greatly 

improved.
XARVIS's unique “bridge type FAN floating structure” is further evolved to 

greatly increase the ventilation capacity.
Equipped with two ACUVANCE cooling fan terminals (including FLEDGE fan)
Equipped with capacitor mounting terminal
Equipped with reverse battery protection circuit (see page 22)
BEC voltage switching (6.0V / 7.4V) function (see page 20)
Supports bidirectional communication with TAO II, Ne-St, FUTABA S.BUS 

system compatible transmitters, etc.

This product needs to be updated to use the S.BUS system (see ACUVANCE 

website).
Equipped with a new program control circuit to secure additional setting items 

for only XARVIS XX
