Ad's Posted January 25, 2010 Share Posted January 25, 2010 Hi everyone, I need help, I've just bought this charger that can do everything that i could possibly need and I'm pleased to bits with it but there's 1 problem, I dont understand it ! I'm not too clever when it comes to electronics. I've read the instructions and I couldn't tell you if they are good or not as it all seems gobldy gook to me. I have some 600 mah ni-cds 4.8v receiver pack and 700mah ni-mh packs too,it says in the instructoins that you should charge at about 1c but when you look at the screen its in 0.1~5.0 A. I know I am making myself sound thick but is there some sort of math to work out the right currents and amps etc. I think this charger is so capable just wish I could be too then I could charge everything till the cows come home. Any help would be much appreciated P.S. why are the instructions so vague on these fine bits of kit? they warn you of all the potential hazards then run out of paper to tell you how to avoid them!!

NigelH Posted January 25, 2010 Share Posted January 25, 2010 To charge at 1C means charge at the pack capacity. Therefore, according to your comments, you would charge the 700mAH pack at 0.7A which is the same as 700mAH.

Roger Adams Posted January 25, 2010 Share Posted January 25, 2010 Further to nigels reply, charge the 600mAH at 0.6 amp max. If you had a 1800mAH the maximum charge rate would be 1.8 amp etc. I also have my 2nd sigma, (The first was stolen) I think they' are excelent.

Roger Adams Posted January 25, 2010 Share Posted January 25, 2010 One other point, if you charge the TX battery through the TX charge socket, don't exceed about 1 amp even if its a high capacity battery because the main board may not be able to safely take the power.

Ad's Posted January 25, 2010 Author Share Posted January 25, 2010 AH its that simple then is it, that makes me sound real dopey.thanks for your replys guess its easy when you know how ay!

Ad's Posted January 25, 2010 Author Share Posted January 25, 2010 Right o now i can at least try with a little knowledge Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 25, 2010 Share Posted January 25, 2010 I would add a note of caution here .....some AA size nickel batteries do not like being charged at 1C, and if the charger fails to correctly identify the delta peak, then they can /will overcook. I find most are best at .5C. Quote Link to comment Share on other sites More sharing options...
Ad's Posted January 26, 2010 Author Share Posted January 26, 2010 So does that mean 0.3 A for the 700 mah then? Quote Link to comment Share on other sites More sharing options...
Roger Adams Posted January 26, 2010 Share Posted January 26, 2010 That would be about .43C, close enough I reckon Thats got me off the 13 posts tally Quote Link to comment Share on other sites More sharing options...
