Lithium Drop-Ins are not so good.
Hi folks and just a followup on some of the info in this thread.
For the passed 18 plus months I have been warning people to do their homework before choosing drop-in lithiums which will be charged directly by an alternator in any vehicle running SMART alternator operations.
While drop-ins can be kept in a reasonable state of charge while running around town, doing short drive. The problem comes about when you go on a trip of just a few hours of continuous driving.
You will get to your overnight stop, run a fridge and some camp lighting and probably goto the vehicle a few times before you go to bed.
Next morning you find your fridge is not running and after some checking you find the two lithiums are flat and have shut down.
I have recently been informed that this is the exact scenario that the D4 in this thread, fitted with two lithium drop-ins, has been suffering from, but something I did not know until just recently is that apparently the continuous running of the lithium batteries in such a low state has actually stuffed at least one of them.
So again, just a warning, do your homework before choosing lithium drop-ins as replacements for lead acid batteries.
