Default charging 3300 battery?

i have a couple battery pak that are 3300 and my charger only can charge at 4amp. is that an ok charge or do i need to get a charger that charge more than 4 amp? beacuse most 3300 battery are charge at 5 amp rigth. if i charge at 4 amp does that meant the voltage will not be that strong?

I charge my GP3300's at 6.5 w/ a .05 peak detect. 4 amps should work OK, but it's the peak detect you want to make sure you have. I wouldn't go over .05.

What type of battery charger yo you have? Charging at lower amps will give you longer run time and be easier on your cells but it will be at a loss of voltage. It depends on if you race or not and how serious you are.

Oh then no problem charging it. What exactly does MV decide? More punch or power?

MV is the value the charger looks for to determine a fully charged pack. ITs looking for 50MV voltage drop after peak voltage starts to drop.

For example:

charged pack is at:
8.90Charging
8.99
9.10
9.11
9.12
9.13
9.15**peak volts
9.14
9.13
9.12
9.11
9.10STOP charger stops

From peak to charger stop the voltage will bounce alitlle once the charger detects the set voltage drop the charge will be done. Basically the charger sees the peak but waits for the voltage to drop indicating a charged pack.

I charge my 3300's at only 3 amps and am able to keep up with even the fastest drivers at my track. How does that actually work?

My runtime is actually longer than some that charge at a greater rate.

50mV is still over 8mV per cell. Just how hot do your batteries get?

You're not heating them to the point where they vent are you?????

I charge at 10 amps on my Tekin BC112c. I usually charge my packs untill fluid is being excreted from all the cells, and the shrink wrap iw tearing because the cells are swelling up.

That usually give me the best voltage. That isn't bad is it?

Windsorguy - they get hot, but no they do not vent. This is the charge Fukuyama recommends and it has worked well for me.
