2. CHARGE SETUP MENU FLOW
Warning: To high settings of charging voltage (Li-batteries), charging current (all types)
or delta peak sensitivity (NiMH/NiCd) batteries can cause explosion and fire!
2-1. CHARGE CURRENT
-
2-2. PEAK SENS
WARNING! To high settings of the delta peak sensitivity can cause explosion and fire.
- Only for NiCd/NiMH. Follow the instruction of your battery or start with 3mV/Cell.
- If battery is 6cells and 3mV/C is set, the charger should finish as 3mV * 6cell =
18mV.
- In case of NIMH battery, charge can be also finished with Zero-peak.
- Set bigger peak sens values if delta-peak often happens.
- "END:DELTA-PEAK " should be shown if charge is finished with delta-peak.
- "END:ZERO-PEAK should be shown if charge is finished with ZERO-peak.
2-3. PEAK DELAY
- This function is not to detect delta peak which could happen at the initial stage of
charging and which could happen due to the chemical reaction internal battery.
Normal settings are 3-5min.
2-4. TRICKLE
- This current is to compensate battery self discharge after NICD/NiMH fast charging.
- As for Lithium battery, CV ( constant voltage ) is activated instead of trickle charge.
2-5. CUT-TEMP
- Connect the temp sensor to battery pack and when it reaches the selected temp,
charging should stop. Normal settings are 35-50°C.
- This function is likely to be used more to prevent battery pack from being
overheating rather than normal charge completion.
2-6. MAX CAPACITY
- This is to set your wanted charge percentage against the selected battery capacity.
- Set half of the battery capacity ( 50% ) for the purpose of the battery storage. Set
120-125% for fully charging of high current NiCd/NiMH batteries and 100-105% for
charging LiPo-, LiIo-, LiFe- batteries and NiMH RTU (Ready to use) batteries.
- If battery capacity is 3000mAh and if you set 10% out of the total max capacity, the
charger should stop charging at 300mAh.
- If "OFF" is set, this max capacity function is not activated.
- If charging is finished with MAX CAPACITY, "END:CAPACITY should be shown.
Set charge currents. Follow the instruction of the battery. Graupner batteries
should be charged with 0.5-1C (f. e. 6N-4200 should be charged with 4.2A).
Transmitter batteries must be charge with less then 2A. Follow the instruction of
the transmitter battery and transmitter.
