Default Battery temp (after charging)

If I charge my cells on about half what they could be charged at, (I charge them at 3 amps now), will they get hot after I fully charge them?

Thanks

Are you getting paid by someone for advertising all that in your signature ? Lots of info, but not what's needed.... Which charger and which batteries?

Your batteries still should get warm. It's just going to take a long time to charge. You should have more runtime charging that low but the voltage will be low.

They should be warm to very warm.

According to one of his "threads" ajg uses cp-1300 or cp-1700 cells to power his project cars...and he wants to verify that his cool batteries are fully charged.

Chill Will,

I heard the theory of cells having more runtime with a lower charge current some time ago. After doin tests at 4 amps and 6 amps I found very little difference in the numbers when discharging at 30A.

When the first 3000,3300 came out i used to charge at 3.5-4 amps, now i charge at 5.5 & they are alot better runtime & punchyness, aleast i don`t have to wait a long time to charge used take nearly a hour to charge at 3 amps

I charge at 6 amps and my cells barely get warm, thats probably because i have 2 12v computer fans in my table and i charge the cells on them..

It works great

You still want them warm after charging, just not too hot. If they are warm they tend to have lower IR and more punch

I adjust the drop back to give me about 130 deg. Anything over 145 IMO is too hot. To get the most out of your charge you should run the car as soon as possible. If you haven't run in 10 minutes start thinking about a repeak.
My 2 cents.

A battery is fully charged at a temp of around 125*F . If you watch your charger and use a temp gun they will usually start to drop in voltage at that temp. This is before the peak detect shuts it off. Ajg.......Watch your charge , you will see it peak and drop........
