Hi Paul and first off, when did you send me an E-mail.
I have actually been on top of my e-mail replies lately, thanks to finally get the business set up at our new premises.
Please Note, the BEST e-mail address to conact me on is
traxide85@gmail.com.
My old Optus e-mail address is being phased out because of reliability problems.
That aside, as long as your alternator operates at 13.8v or higher, and I am pretty sure yours does, you should have no problems with charging a lithium battery directly from your alternator, via your DT90.
I already have a few Defender owners who have swapped out the lead acid battery for a lithium and it was a straight swap with no modifications needed.
Do you know your alternator’s amperage?
