I was wonder if anybody ever researched the discharge rate in amps of their receiver pack. I know this will vary, but just curious if anybody has read or figured it out? thnks
 
My intellipeak charger has dual discharge rate. it recommends 2A for 1500mah or less.. the other is 10A for higher capacity. Not that this is a rule of thumb but I suppose a rough guideline maybe?.?... :shrug:
 
What are you trying to get at I'm not understanding your question.
Are you wondering the best discharge rate for your pack or the draw that your particular electronics package is at?
 
i was just discharging my pack at 2.5 amps and it took 37 minutes and was wondering how accurate that was to actual run time. Say I was in a 45 min main would my battery last? I'm sure my servos and receiver do not put a 2.5 amp draw on the battery so I would last the main, but was just wondering how much draw two servos and a receiver would put on a battery while racing. Years ago when I raced elec. I was taught how to solder a certain amount of bulbs together to simulate a race to discharge my battery pack so I could charge them.
 
You can add up all the numbers given in the specs of your equipment and make an intelligent guess. Or you can run you RC till the fail safe kicks in to be sure your exact.:ahh:
 
w/ Nimh batts I was told to discharge them around 1.5 times the capacity of the pack for quick cycles during the day but if you equalize the cells then do a 20 - 30AMP dump before storage...those numbers are for race packs w/ over 3300mah ratings.....I would assume the percentages of those numbers would carry down to RX packs....so I discharge mine at 3Amps and charge em at 1.9Amps......those are 1400mah RX packs though.....and there is no way you are having a constant 2.5 amp draw in your rig for a solid 35 mins so your packs should last alot longer than that....remember they may only be drawing 1 amp for most of the time you're running......
