RAMFAN EX50Li User manual

1. If both battery(s) and AC are connected, the battery(s) will begin charging
after 15 minutes of idle time.
2. Indicator lights will show charge state during charging (See insert). Charging
should complete in about 4 hours, with the Indicator lights turning green.
Should the Speed control be turned on during the charge, charging will stop
and the fan will start. Charging will begin again after 15 min of idle time.
3. After charging is complete, the chargers will maintain the battery(s) by
keeping the blower connected to AC.
4. In service storage. Keep batteries topped by keeping blower connected
to AC. Battery charge lights will go out as the controller and batteries are
programmed to reduce leakage to a bare minimum. Use wake up button to
check charge state.

1. RAMFAN R2-360-AH-U lithium-ion battery packs are rated 40v 6Ah. The cells
are Samsung 18650 rated 3Ah.
2.FactorsaectingPerformanceandCyclelife.
• Batterypackswilllastsignicantlylongerwhenruninpairs;therewillbea
lower amp draw on each cell.
•The number of discharge/charge cycles depends on how far down batteries
 aredischarged;calledthedepthofdischarge(DoD).Twobatterypackswith
 anaverageruntimeof20minutes(50%DoD)orlesswilllastsignicantly
longer than two battery packs with an average runtime of 40 minutes
 (100%DoD).
•As delivered, two new battery packs can power the blower for about 46
minutes. This decreases as the cycles pileup as shown in the table. Battery(s)
will need to be replaced as they age.
•Keep the blower attached to AC while not being used. This will keep them
charged and lengthen their service life. An idle battery will slowly lose charge
and possibly become unusable.
• Thenumberofdischarge/chargecyclesdependsonDepthofdischarge. 
 Depthofdischargeistheaveragecapacityusedperdischarge.Forexample,2
batteries with a 40 min capacity used for 20 minutes on average will be a 50%
 Depthofdischarge(DoD).1blonger.
Depth of Discharge in minutes-2 packsDischarge/Charge Cycles (Life)*
46 min. 250-500
20 min. 800+
10 min. 1500+
* Estimate only. Battery packs lose capacity as they are used. This number represents the number of cycles,
after which the battery capacity has reduced to 60-70% of starting capacity, commonly time to replace. If
battery capacity reaches less than what the user requires replace with new.

The EX50Li will run with one or two 40v 6Ah Li-ion battery packs. Each pack
yieldsabout23minofoperationatfullpower.Extendedoperationisachieved
by reducing speed. The batteries may be swapped during operation.
AC voltage can be applied while running on batteries and the ventilator will auto-
switch to AC power. Conversely, the AC power can be removed and the unit will
auto-switchtobatterypower,ifsucientchargeremains.
The integrated battery chargers will charge one or two fully discharged battery
packs in 4 hours or less.
