Ok ... here is an example....Others have said if you don't have a smart alternator you can drop a fogstar straight in. How many people have done that.
I've an electroblok 119, and an MPPT solar regulator with lithium profile.
With the fogstar BMS
I have on my Motorhome a Sargent EC325. That has a maximum voltage output of 13.8V for both Mains Charging and Split Charging.
It is pretty rubbish for charging Lead in fact. There are no settings to select Gel, AGM or whatever.
British motorhomes and campervans with similar limititions are very common and are still being built to this day would you believe!
Now on the one hand, it is no worse at charging then the lead, but I have spend loads of cash on a battery that I have been told I can just drop in and the result is I have a battery which I cannot use fully.
I "drop in" a Fogstar - or ANY Lithium battery for that matter and it will NEVER charge properly, and may overexert the charger, possibly cooking it.
A lot of these system are not designed to run their chargers at full power for extended periods and have both a maximum supported AH and a "do not use with lithium" warning. Put in a big lithium and any warranty is up in smoke along with the charger.
On some setups, you can indeed "drop in" a lithium battery without batting an eye as they have charging systems that will charge a lithium battery (so it is a "duh" moment there), but for a vendor to make such a blanket statement that it drops infor just about anyone and then tuck the truth away down in the weeds is misleading and disingenuous and it makes me not trust the company.
