My Lipo trials

[NRG]

Really interesting. Do you know what the chemistry of the LIPO is? Is it marked on the battery anywhere?

Lipo refers to the construction, they are still lithium ion with compound cathode probably cobalt...

Great info, thanks for sharing!!

I guess you will be required to use this charger to charge 22V cells, right?

By the way, how do you charge your set of 18.5V batteries? Do you charge each one of these separately or do you use more than one charger to save the time?

How long does it take to fully charge your set of 4 batteries?

Thanks
Alex

My charger is more or less the same as that one, but I didn't get that fancy box to put it in so it was a bit cheaper. It has the same case, buttons and screen, I have to charge one pack at a time, which take about 3 hours each because i only charge at about 2.5 to 3amps. There's a fast charge function, but I don't use it because I never need an urgent re-charge. Might be different next week when we go to the Presteign show because I think I'll need to re-charge while I'm going along if my 44v packs arrive in time.

This is precisely what worries me about these RC batteries. I don't really want high capacity LiCoO2 batteries in the house even if it does save a few pounds. My 24V 10Ah LiNiCoMn battery from BMSBattery only cost £85 including a BMS, charger and delivery, although that was a special offer. It is much safer and so far it has worked perfectly.
