i am looking at changing my battery system to lithium. I have settled on the enerdrive 300 amp slim battery. However, enerdrive want me to buy a complete drop in kit. My problem is that I already have a Enerdrive AC 60 amp charger which has a lithium profile, a Tristar solar regulator, a enerdrive 40 amp dc to dc charger which can manage input from the tug and solar. I also have a Victron battery monitor.
IT puzzles me that i am told by Enerdrive that I need to buy a kit to get the battery when i already have most of the components. I am also told that I need to reconfigure the Tristar to Lithium, when it is going to feed directly to the dc to dc charger which is already configurable to lithium. Perhaps I could bypass the Tristar altogether and use the Enerdrive dc to dc solar. On top of this, nobody seems to know who is capable and experienced to do the work Even though it appears to me to mostly plug and play.

mmm........ I can understand your frustration.... but I guess Enerdrive sell a system with these batteries.... If I had a few (expensive'ish) bits I'd go a different battery. Easy enough to have a metal shop make a box to suit (I did ... about $200).
I run the enerdrive dc2dc as a solar regulator (as well as normal dc2dc function)... 800w of solar .... works well enough..... only downside is that it won't use solar when dc2dc is functioning.... so 50 amps is max if cabled appropiately.... where with a seperate solar reg you'd get solar chargjng as well....

I will pay for anything that is necessary for the protection and maintenance of the system, but cant see why I need to junk components that are compatible.
You don't need to junk any of the gear you already have. Enerdrive make a complete package that is all plug and play as you say, but they are not likely to sell you the important bits that need to be added to the system to get the bits you have to work with the lithium battery. If they sold you these parts they would have to tell you how it all goes together and that would cut out the service/install network they have built up throughout the country. they will only supply a complete kit because they don't want to take on the risk that there could be issues using the great you already have, even if it is Enerdrive gear. It will also effect the profit the installer will make because they are supplying less items.
Just because a charger has a lithium setting doesn't mean it is capable of connecting directly to a lithium battery, a BMS is required to control these charging devices because they don't actually get any feed back from the battery.
I'll send you a PM
