Input Amps isnt an indication of power output of the battery. Only the mah you get on discharge is a reliable indication of the battery's condition.

When charging, the reading your charger gives is just a mathematical equation of the charge rate multiplied by the time the battery was charged for. When you discharge the battery on a decent charger discharger it will record the correct figure.

Well in my break in proses I have just gone through 2-3 tanks idle at 2 mins cycles because it was too tight and I have now gone through 5 -6 tanks of InitialD WOT style, do I need more or can start to run and lean?

:nod: You're absolutely correct. The main point I was aiming at was that through careful battery management, the capacity of the battery is optimised.

Cheers, Mark.

You can but its best to not lean it all the way. Drive around with the engine slightly richer for a couple of tanks first.

So,should I be getting a battery discharger for my 800 packs I just got for my 710??

Nah, that would be not a good investment. When the batt stars to fade, take the car in, and just run the batts so that the servo cannot turn any more, that would be a sufficient discharge process.

If your budget extends far enough it wouldnt hurt to have one.

I have a CDC charger that has an onboard discharger. It is a perfect charger for gas use. Does enough for the reciever, glow, transmitter and starterbox batteries to keep them healthy and happy.

Another option is the new Futaba RX battery checker. But it does not do the glowstarter.
