Hello. I'm an RV owner and still in the process of learning about Lithium batteries. I have a Progressive Dynamics converter and here is a quote from one of their FAQs in response to question of using the lead/acid charger to charge a lithium battery:
"Yes, if you are willing to live with an expensive battery that is only partially charged. The Normal Output voltage of the PD9200, PD4000 and PD4500 Series voltage provides only 13.6-volts and a full charge voltage for Lithium needs to be 14.4 – 14.6 Volts. The PD9200, PD4000 & PD4500 Series Charge Wizard will initially jump to 14.4-volts in the Boost Mode when first connected to 120 VAC power and will remain there until the battery voltage reaches 13.8-Volts, then automatically drops down to the Normal Mode of 13.6-Volts. The faster charge rate of Lithium means that in the Boost Mode it will reach this 13.8-Volt point after only a few minutes of recharging and then the charging current will drop to ZERO AMPS and will not add any additional charge to your Lithium Battery. This lower charge state will not damage your battery, but will eliminate most of the advantages you paid for."
From one of Will's videos he was saying to increase the life of lithium batteries keep them charged between 10/20 to 80/90 percent. So if I use the PD converter to charge to 13.6v and be careful that I don't discharge below12% wouldn't the PD charger work?
