Default Equalizing To 0.7Volts

Is it possible to equalize newer generation batteries like GP4300 and IB4200 down to 0.7Volts without damaging the cells???

I know that GP3300 can be equalize down to 0.7Volts per cell but what about newer batteries???

I don't have any information on the GP4300's, but always keep the IB4200's above 0.90 volts per cell, or you will loose preformance.

There is nothing wrong with taking IB's down to .7V, you just do not want to go below .6V

See EA's set up here

Here is what you do. Even EA or Brood agreees

Discharge 20-30 amps to 5.4 volts after your race. Leave it at that if you plan to race next week. If you plan on using that pack again, You can tray it to .7-.9, (not any lower then .7) but dont let the pack sit at .7 for half teh day, only enough time to let it kool after the discharge/traying time.

With my GP3300's a long time ago, I used to Tray to like .5 all the time. and occasionally .01-.03 just to refreshen the pack, and I still stayed in teh 3500mah range with awsome punch. These were teh Fusion 1.185's

Yes..... I did that in the past...... it's moron things.

0.9V is the safest.

( I'm talking about IB 3800 and 4200 ..... I don't know for other batteries. )

So if I discharge my newer batts like IB4200 down to 0.7volts it wouldn't harm the batteries right???

I need confirmation before doing something stupid like killing new cells...

What is the reasoning behind wanting to pull them down to .7V instead of the more widely accepted .9V?

Coz I was trying to make myself a discharging tray that is simple and cheap.

The only diode that is cheap enough has 0.7volts cut off while the ones that have 0.9volts cut off cost a BOMB...

.....then the costs of having lame IB4200 would be NUCLEAR

BTW, if you immediately charge it again, I think it should be fine.
Never let IB cells left empty........ always keep some 500Mah to 1000Mah capacity before you store them.
