help with LiPo charger
Im new to the LiPo batteries and I bought a Protek prodigy 65 ac charger and a protek 5000mah 2s 35c lipo. I read through the instructions a couple times but still cant figure out whats the best way to charge the battery. I am able to balance charge it but at what amps, how long do I set the safety timer, and the capacity shut off? Also with the storage mode have no idea what to put the settings at

No reason to use the capacity or timer safety functions, just turn them off
Charge the pack at 5 amps Whenever your packs are not in use they should be kept at storage voltage (50% or 3.85v / cell) Cheers |
and when I put them on the charger in storage mode would I set that at 5 amps as well?

Not familiar with your charger
Some will only charge up to storage voltage from empty Some will only discharge down to storage voltage Some will either charge or discharge depending on the starting voltage of the pack If charging up use your normal charge rate If discharging you will more than likely be limited by the discharge power of your charger, regardless of what rate you enter Most have very small discharge current rate limits (5 - 30 watts) Check the spec sheets for your charger and it will tell you what the discharge limit is Simply divide it by the pack voltage and you will work out the max discharge current Example 20 watt discharge limit 3s pack 20w / 12.6v = 1.58 amps max discharge current Cheers |

the charger is capable of charging or discharging in storage charge mode depending on the voltage when connected. Here are the specs i got off a main.
Specifications: Input Voltage: AC 110V-240V, DC 11V-18V Charge Current: 0.1-5A, 0.1A step Discharge Current: 0.1-1A, 0.1A step Power Supply Output: 5A NiCd/NiMH Cells: 1-15 Cell LiPo/Li-ion/LiFe Cells: 1-6 Cell Lead-acid (Pb): 2-20V Temperature Sensor Port: Yes USB Port: Yes Balance: 2-6 Lithium Cells Case: aluminum Display: 16x2 character LCD Dimension: 135x125x34mm the instructions dont give much info. |
If it has a discharge limit of 1 amp then use that
A 1 amp discharge of a 5000mah sized pack will take 150 minutes to take it down from full to storage voltage A lot easier to run the pack in your car down to your LVC cuts in Throw it back on the charger and charge it at 5 amps before storing Charging at 5 amps will take 30 mins from empty to get to storage voltage Cheers |

Pg 19 of your manual says this charger is set to discharge or charge a lipo to storage conditions as dictated by the voltage when you connect it. Due to limited discharge wattage (5watts), it will be faster to take care of any needed discharging in your RC unless the voltage is pretty close to storage value. I make sure mine are charged to storage since that's faster. |
