Lead Crystal batteries for non-EV application?

Post by rhills » Thu, 12 Apr 2018, 15:25

Hi Guys,

In another forum I haunt, someone has asked about replacing existing AGM "house" batteries in a Recreational Vehicle with some "Lead Crystal" batteries.

From my brief reading, Lead Crystal batteries are the absolute beez neez and will cure everything from the common cold to AIDS. So, I am suspicious.

Given that house battery capacity in RVs is typically around the 200-400AH mark, weight is much less of an issue than it is in an EV and charge/discharge rates are less important than safe maximum discharge and life expectancy, are LC batteries a better alternative than Lithiums in this context? The other consideration here is charging. Typically an RV will have at least 3 different chargers for house and starter batteries (240V, Alternator and Solar Panels) and they usually have fairly simple starter/house battery separation systems that typically charge all batteries in parallel which I understand is not always the best plan if your starter battery is Lead-Acid and your house batteries are lithiums.

Has anyone in this forum had personal experience with Lead Crystal Batteries, or cause to test or research the claims made for them?

Cheers,
Rob Hills

Snake oil. They're c$%p. Check some marine forums.

I wouldn't dismiss the weight saving of lithium in a motorhome.

A smart all in one dc/dc converter - mains battery charger that can iron out alternator/mains power charging issues. Some can also Have PV inputs.

The only issue I can see with batterys and motor homes ( its the same issue for all batterys) is heat.
