Would This Work??

Hi people

Just found this site and came across the Victron Battery Protect

http://www.onboardenergy.com/acatalog/Battery_Protect.html

Just wondering would it work as a charge controller.

That's a low-voltage disconnect (LVD) so far as I can see: the other side of the battery from the charging source!  Also good to have of course...

Thanks Damon

I understand what you mean.

But it also prevents over charge or do all LVD's do that?

As you can tell i know nothing about LVD's.

But it seems to me that if it prevents over charge that it would work as a charge controller,granted maybe not a very good one.I know that you probably could'nt connect a dump load.

Or am i way off??

I was not going to say anything, but when they talk about $50 shipping, and $110 or more for the device... it starts sounding like a robbery in progress!

It is an LVD.  I don't see how it tells when to do what it does do, if it does do what I think it does, when it does do it, if it does.

How much wood could a woodchuck chuck...  :-)

I'm not sure why they call it 6v to 35V when it looks like only 12V to me.

(will a 24V battery, run down to 10V, start a 24V motor?)

This wasn't supposed to be a sales pitch, but my circuit with enough extra fets, some effort, and a few extra 'bits'... would cost less than half of just the shipping cost for that thing.

I didn't do more than glance at the datasheet, but I guess that these disconnect the load from the battery to protect the load if the battery voltage goes too high, eg if the battery side goes open circuit while being charged for some reason.

Again, my cheapo Morningstar controller does load LVD and overvoltage disconnect as well as (and separate from) the charge controller on its input side.

My £40 charge controller has over voltage protection and low voltage disconnection. Shows that cheap controllers aren't always the worse and the most expensive aren't always best.

I bought a battery protector many years ago designed for automotive use and would handle full starter current.  Nice for those times you left the headlights on.  Wish I could find it since I run the camp off my car battery.  It was designed to disconnect when you still had enough to start the vehicle.  It was also smart enough to not disconnect in emergency situations like when the flashers were on.  If it detected pulsing current it would not shut off.  Wasn't that expensive.

Thanks for the help.

Its interesting to see the price differences between the U.S and Ireland

Was looking at the prices for Trace C40,I wish i lived in the U.S,they are around $130.

Here in Ireland the Price is €260($362).

Its time to head back over the water and and buy a couple
