FWAL Posted May 12, 2013 Share Posted May 12, 2013 Just received my first LiFe 6.6V 1600mAh battery yesterday. I wasn't sure if it came fully charged or 'storage charged' so thought it best to plug it into my Turnigy accusell 6 charger. With this charger you choose the charge current, ranging from 0.1-5.0 A The battery instructions states " Vapextech battery packs can be charged with a maximum current of 1C" Being a relative newcomer to LiPo/LiFe/Lilo batteries and current is measured in Amps how does one convert 1C to amps?

Matthew Clive Posted May 12, 2013 Share Posted May 12, 2013 You take the capacity and divide by 1000 so you can charge the pack at 1.6 amps.which is the same as 1600mA. 1C means 1x capacity Quote Link to comment Share on other sites More sharing options...
simon barr Posted May 12, 2013 Share Posted May 12, 2013 1600 mAh = 1.6 amps.... (1000 mAh = 1.0 amp) Quote Link to comment Share on other sites More sharing options...
crispin church Posted May 12, 2013 Share Posted May 12, 2013 A123 can be charge higher than lipos Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted May 12, 2013 Share Posted May 12, 2013 Genuine A123 LiFe cells can be charged at silly high rates, Ive pumped 'em up at almost 8C occasionally. Cant say I am familiar with vapextech LiFe packs though, I thought they made LSD cells/packs similar to Eneloops, called "vapex instants" which are effectively NiMH Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted May 13, 2013 Share Posted May 13, 2013 Tim, these are soft cell packs, not cans like A123. I use 1C for my HK LiFe packs, so far they are lasting well on that regime. Quote Link to comment Share on other sites More sharing options...
Steve Hargreaves - Moderator Posted May 13, 2013 Share Posted May 13, 2013 I use 1C for all my (foil) LiFE packs too because they are relatively low capacity.....1C equates to under 2A for all my airbourne packs. An exception is the 1800mAh battery I have in my Tx.....1.8A for 1 hour seems like quite a lot to put through the transmitters wiring so I only use 0.5C for that battery. Given that it only needs charging every few months this seems a small penalty to pay.... Quote Link to comment Share on other sites More sharing options...
