series or parallel. The operation may lead on injuries or property loss.
(12) It is prohibited to make the lithium battery protective circuit board or battery
management system power system in series or parallel with other system. The operation
may lead on injuries or property loss. If necessary, contact with HELI technical
department or after sale service department.
2) Lithium battery using notes
(1) Charging temperature range: 0-40℃. Charging under low temperature is bad for
battery. Please charge the battery after using at once in low temperature that is below 0℃.
(2) Discharging temperature range: -25~50℃, discharging capacity under low
temperature (-25~0℃) is poorer than under normal temperature. This is normal. The
battery can be used under 40-50℃, but high environment temperature especially staying
that environment for a long time will speed up the aging of battery internal material and
shorten battery service life. So it is not recommended to use the truck under this
temperature for a long time.
(3) Storage and longtime operation below -25 ℃ or above 55 ℃ are prohibited.
(4) When the truck has to be stored for a long time, keep the battery electricity to be
40%~60% and store it in dry and shady environment and charge the battery according to
the manual to prevent over low electricity because of self discharge in long time storing
which may cause irreversible capacity loose.
(5) Lithium battery self discharging is affected by environment temperature and
humidity. High temperature and humid temperature will speed up battery self discharging.
The battery is suggested to be stored under -10℃-45℃ dry environment.
(6) Unauthorized person are not allowed to touch, move, disassemble battery and
corresponding high voltage cable or parts with high voltage marking.
(7) If the truck suffers from violent impact, stop the truck in safe area and check if
