checking batt. mah
 
Dumb question maybe ....Using the Hyperion 0610inet charger, is there a way to connect my battery (Neu 5s 4900) to see how much Mah's are in it at that moment ??...what I'm doing is using "store" mode... i takes my batts to 60%...is this 60% of what it was when i connected the battery??....or 60% of the total capacity of 4900 ??....so in other words should i fully charge my battery to 100% first,then use "store" mode to bring it to 60% ?? or can i use "store" mode at any time and does the charger know to store it at 60% of 4900 mah ??.....LOL,am i making any sense ??...basically i was told to store my batteries at about 50 to 60% of capacity if I'm not gonna use them for 3 or 4 weeks so i was wondering if theres a way to check my batteries capacity ....thanks for the help

Not really. You can use the voltage to get a pretty good idea though.

Get a good voltmeter. When the battery isn't under load the voltage corresponds to how much mah is left. Like a 4.2v it should be full. I would store it at 3.6 or 3.7, and charge it when it gets down to 3.4 or so.

ok ...that seems easier...i do have a voltmeter and checked each cell and there all at 3.88 or 3.89....am i good there for storage ?? and would checking them about once a week be good ??....thanks again for dealing with the noob questions

That would be fine. You just don't want them 100% charged or so low that they go below 3v.

When in store mode, it charges to 60% of the total capacity based on your input. Remember that before charging, you input your batteries capacity (1000mah, 5000mah etc.), type(Lipo, NiMH etc.), configuration (2S, 3S, 4S etc.), charging rate plus other characteristics. So ensure you have inputted everything correctly in order for the charger to function properly.

yes,thats what i was hoping to hear ...so it's 60% of what was inputed (4900 in my case) the total capacity of the battery....thats what i have done and now i will just check it every few days till i get to run them again...thank you guys for the help.....maybe there is hope for me learning all this "electric" stuff....:yipi:Iv'e read so much on here i have brain overload ,when i go to actually do it,ive forgotten what ive read....thanks again guys for the help
