melvins913 Posted March 21, 2015 Share Posted March 21, 2015 Hey guys, I used a lipo for the 1st time today after finishing my losi build, and I'm charging it back up but in storage mode as I won't be able to go out with the car again for a few days. The battery has been on charge for over 1 hour 30 mins, is this normal? The charger is saying that the sells are both at 3.84v and charging at 0.7a Im using a overland rc6. Cheers guys Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 21, 2015 Share Posted March 21, 2015 Sounds right to me. Mine seem to take an age to reach storage charge! My charger is set for a 2 hour cut off and quite often I have to start it again. 1 Quote Link to comment Share on other sites More sharing options...
melvins913 Posted March 21, 2015 Author Share Posted March 21, 2015 Thank you for your reply everclear, thats good to know. Ive been reading that storage charge should be between 3.85v and 3.9v Is this correct? Cheers Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 21, 2015 Share Posted March 21, 2015 (edited) Again, I would say that's about right. I'm really new to this hobby and lipo's but if I recall that's roughly where mine sit. Someone will correct me fairly quickly if I'm wrong Edited March 21, 2015 by everclear1984 1 Quote Link to comment Share on other sites More sharing options...
jonb82 Posted March 21, 2015 Share Posted March 21, 2015 Storage charge takes ages, i just adjust end voltage to 3.85 and then do a normal balance charge. 1 Quote Link to comment Share on other sites More sharing options...
melvins913 Posted March 21, 2015 Author Share Posted March 21, 2015 This Is what the screen says I did cancel the charge and start it again after 90 mins just to make sure i had set it correct. As its sitting at 3.81 I might just take them off charge and leave them at that. The battery is stone cold so Im not sure if its actually charging it Quote Link to comment Share on other sites More sharing options...

The battery is stone cold so Im not sure if its actually charging it All of my batteries never even get warm during a charge. I've got some old Turnigy Nano-cells and Zippy Flightmax and they always stay cold. I like the idea of setting the end voltage and running a balance charger, will the discharge the battery if needed? 1 Quote Link to comment Share on other sites More sharing options...
jonb82 Posted March 21, 2015 Share Posted March 21, 2015 No it doesnt discharge unfortunately!!! 1 Quote Link to comment Share on other sites More sharing options...
evssv Posted March 22, 2015 Share Posted March 22, 2015 If I stop and my lipos r around 3.70 or 3.85v or anywere inbetween I leave em at that and don't bother storage charging them. ..but if there below this then I will stick em on. . 1 Quote Link to comment Share on other sites More sharing options...
jamesd Posted March 23, 2015 Share Posted March 23, 2015 I have this charger and if I remember rightly (its been a while since is used it) storage charging only charges at 1 or 2 amps and that's why it takes a lot longer. Quote Link to comment Share on other sites More sharing options...

sjw Posted March 23, 2015 Share Posted March 23, 2015 I don't think it's just that the storage is at 1A. I don't really have an answer (mine is the same) but it can easily get to 3.81 and sit there for an hour or more. I store between that and 3.85. I just balance charge it and stop it at around 3.85V - it's waaaay quicker than a storage charge. Also, my fan is VERY noisy when I switch it on. It groans a bit and goes quiet after 20 seconds or so. It's done this from new - is anyone else's the same, or should I really get it swapped/fixed?

evssv Posted March 23, 2015 Share Posted March 23, 2015 (edited) my fans quiet then louder. ..goes on ...then off...it's never concerned me tbh Edited March 23, 2015 by evssv Quote Link to comment Share on other sites More sharing options...
everclear1984 Posted March 23, 2015 Share Posted March 23, 2015 I have 2 chargers, one noisy, one quiet. Both work equally well. Quote Link to comment Share on other sites More sharing options...

NuttyProfessor Posted March 24, 2015 Share Posted March 24, 2015 My Turnigy 400w mega has 2 fans, when the second one kicks in, sounds like jet turbine winding up but it charges 2x6s 5500mah in parallel in 50 mins mines in the garage so cant hear it.

Zoea Posted March 24, 2015 Share Posted March 24, 2015 I think the storage charge is between 7.6 and 7.8 (maybe 7.8 volts*) *please don't take this advice over your lipo charger's actual storage result I have an accucel 6 which will storage charge or discharge a 2s lipo to 7.6 and sometimes it does take ages since the max is 1A either way (charge or dis). I am happy with it but don't mind occasionally stopping it a little high since I once read this idea that storage charge might be ok a little above 7.6 Quote Link to comment Share on other sites More sharing options...
