Hi Willie, we are in the process of changing to lithium set up and have renew the complete charging system including DC/DC so the Projecta is now surplus to our needs . It is a great charge for AGMs and Lead Acid, and is not so old . We also have the original B/T charger 2007 model if any one is interested ,that has the small remote and the extra earth added to the chassis ,no battery temperature sensor but can supply with another if need be, both chargers are in good condition.


Regards Dave.

Dave, shouldn't the GEL setting be suitable for lithium batteries on that charger?

Hi Stephen, I rang BT workshop about this and they informed me it would not be the right charging curve for Lithium ,it also depends on what sort of Lithiums. As far as can find out the charge rate needs to be 14.8 and 14.4 float , but anyway there is a new programable charger in place now which does Lithium.

EV Power (WA) has a LiFeP04 dedicated charger 45A, ($395) Rod the engineer/owner there is very help full, not paranoid like some.

My lithiums are 13.8v float and need 14.6v to equalise cells ,
but check with the battery manufacturer as to what theirs need they can differ

Make sure you have a high and low voltage cut out in the form of a "battery management unit" which also checks cell balance

Cheers Ken
