Hi,
I have some questions regarding the amount of time it is taking to charge my 100 Ah Dragonfly energy lithium Battery. We do a lot of Boondocking with no plug in and have a Furion 165 watt solar panel on the roof and I purchased a Renogy 200 watt solar which has its own charge controller. I plan to eventually purchase another 100 Ah batter however wanted to gauge the performance of 1 battery before adding a second. I also have a 2200 watt Honda generator for those cloudy days. I was told by the dealer that I could expect to fully charge my battery from a discharged state in 3-4 hours with my generator or plugged in to house power. My converter is a WGCO model WF-8955-AD-GE and it has an a lithium auto detect sticker on the outside. I was told by the dealer that this converter would automatically adjust the charge based on the battery type and is fully capable of charging a lithium battery to 100% soc. When using my generator or when charging from my house power my average charging numbers are as follows (these numbers are with the refrigerator turned on therefor the amps are net of the refrigerator use which seems to use an average of about 5-6 amps):
During our first camping trip with our new trailer, we ran the generator for 4 hours and battery monitor went from 29.8% to 54% with the refrigerator on. -voltage read 13.5%
I compared my generator charging time to house power charging time when I got home. I charged battery through the converter with my generator and receive a net amperage of 10 amps and after 2 hours I plugged trailer into house power and receive the same numbers; charging an average net gain of 10% charge/hour. Based on my charging performance to date it would take me approximately 9 hours to fully charge my batter from a 10% soc. I certainly expected a faster charge base on the information the dealer provided me with. I have purchased a voltmeter however not knowledgeable with how to use it to aid me in problem solving my charging issues. Sorry for the long post however I hope there is sufficient detail that someone with experience/knowledge in this area could help me in figuring this out. All comments/advice are very much appreciated.
Thanks in advance,
Henry
