Power Drive Chargers???

[Sambuca]

I have a Powerdrive 2 charger and a Powerdrive 3 charger. Can anyone tell me the difference in the two? I am also wondering if I were to sell one which one should I keep. I only have two because I thought my charger died but it was the OBC. So now I am going to get rid of one.

Sambuca,
I asked the same question a while back, but I can't locate that thread right now. As I recall the answers I received stated that the Power Drive 3 has a little bit different charging algorithm in it. I personally would keep the PD 3, as it is a newer unit.

Yes! Keep the PD3

my only experience is with pd2 but it only has an on/off relay controlled by the obc
the charging algorithm is regulated by the obc

Thanks for the replies. I figured as much. was just curious if anyone actually knew the difference. I can't find anything online.

As far as charging the PowerDrive 2 and 3 are compatible.

The Powerdrive3 relay board has some extra circuit in the activation that allows the newer OBC to detect when the relay voltage suppression device has failed.

The older OBC designed for the PowerDrive2 will not take advantage of that feature.

Sambuca,
And that answer from Sergio is the one I was looking for and could not find.

Sergio,
Thank you.

Thanks for the replies. I assumed the 3 was the one to keep just didn't know if there wss major differences I do notice the power drive 3 starts to boil the batteries almost immediately. Any thoughts

If the output amperage is the same, it should be no different. I would assume you are seeing a little more amperage in the beginning on the 3. Mine is a 3 and pegs out the 15 amp gauge as my dads PD1 goes to 13-15 and slowly works up and then charges down.

I think it was David (TahoeDawg) that told me the PD3's hit a little harder on intial start-up. And it could also be the algorithm in mine since it is an '07 and his is a '96 as Sergio was pointing out.

They're both good chargers. I prefer the PD2 because it's smaller, doesn't get as hot, and repair parts are MUCH cheaper.
