Default what's the diff btwn 0-30 discharger & novak smart discharger

Hi, I am new to electric. what is the difference btwn 0-30 discharger and the novak smart discharger? All I know is that the novak will stop at 0.9 V. the the 0-30 will drop to 0 v. will 0 v hurt the battery? which one should I get?

One big difference between the two is the discharge rate, 0-30 is at 30amps, the Novak I believe is at 2.5amps. I use the 0-30 for a quick pull down on the battery after I run the car. I use the Novak tray to equalize the pack (at the rate I want, ie. .08) right before I place the pack on the charger.

If you are using IB type batteries, you do not want to pull them down below .07. I usually use the 0-30 until the lights go out, then I pull them off the 0-30, and set my Novak tray to .07 and it takes 2 to 4 min. to get them equalised on the Novak tray. The important point here is that you need to monitor the IB's on the 0-30, not advisable to leave them on too long after the lights go out. If you are using GP type batteries, it makes no difference, those you can take right down to zero.

The Integy 0-30 is a 30A discharger, and it will take all all your cells down in voltage at a 30A rate, with no cutoff, the only way to measure what its doing is by the lightbulbs. The novak is an equalizer, it dischargers much slower (5A I believe) and stops discharging each cell at a cut off you select, therefore equalizing your pack.
I would use the Integy to bring the cells down first, then equalize on the Novak.

Hold onto your horses though, new Integy discharger on the way, 0-90, should rival the ubiqutous muchmore CTX-D

Yeah, 90A discharge will do wonders to a pack - . The new D-90 looks cool, but not nearly equal to the CTXD2 or DPD, IMO.

The Trininty DPD does both correct? Discharges at 30 Amps and equalizes?

Yes. The DPD will pulse discharges at 30A, where the 0-30 does 30A cont. discharge.

If I use the 0-30, I should pull the battery off right after the lights goes off, then put it on the novak and set 0.9 or 0.7?

Or for no brainer and another $100, I should just get a ctx d2 which will do the job of both novak and integy?

Yes, remove the pack from the 0-30 when the lights go off.

You would want to put the pack on the smart tray before you charge it, give it some time to cool first after the 0-30. .9 is the standard setting (most commonly used), but some people are using .7 on the new 4200's.

but..

You can't go wrong with the CTXD2 Only one extra item to carry in your pit box.
