LiFe Batteries
andrew wallace:
does anyone use LiFe batteries
i bought a couple of 6.6v 1600Mah LiFe batteries for a new thermal model and even bought a charger to make sure i was charging them right as i know nothing about them. my problem or my worry is how fast do these batteries charge??
I had a bit of a senior moment at the start with them and the battery checker but got that sorted i used the battery to set up the controls of the model and was surprised at how much just setting up the controls had taken out of the battery but when i went to charge it again it only took just over 2 minutes for the charger to say it was fully charged and that was only at 0.5amps i don't like charging any higher than that
The batteries are designed for thin fuselages and made for servo's that need or like 6v
As it stands i have no faith in the batteries so i hope someone out there can shed a bit of light on the matter :-\ :-\ :-\ :-\ :-\ :-\ :-\ :-\

Hi andrew,
Battery should be charged @ 1.6 amp at 6.6volt and should at this setting take one hour from discharged state to fully charge.

Andrew,
senior moment, we are all having them these days. On your battery checker is there an option for checking LiFe cells, the capacity reading will be different to a LiPo or NiCd. LiFe are grand but like all batteries they need the correct looking after.
Sometime I have found I need to give the batteries a tickle before checking the capacity, I don't know why but it works.
See you in a few weeks
Ralph

Hi Ralph
That was my senior moment I was checking it under lipo until someone pointed out my mistake.
Even charging the battery to storage only took just over a minute again at 0.5 amps and to me that's not right
I've ordered two new 7.4v 1800mah lipo's for piece of mind

Last resort, always a good one, try cycling them with the charger. The numbers won't lie
