Hello!
I'm new to the site, but have been dabbling in various solar DIY projects over the last 15-20 years. I currently have a 135W panel charging a couple of SLAs via a Renogy Wanderer 10A, which I use for LED lighting and USB webcams for a feral cat shelter that I built a couple years ago.
What I'm looking to do next is use a pair of Astronergy 360W panels with a Renogy Rover 20A Li to charge a 6S16P BMS-based pack that I built. The 18650 LiPo cells have been harvested from laptop battery packs, and the 96 batteries that I selected for this project are all able to maintain a decent charge. They're going to be housed in a locking, heavy, steel ammo box in case something bad happens.
What I'm struggling with is the user-defined parameters for the Renogy Rover. I have the Bluetooth module, so I can program the parameters, but I'm not sure if what I have come up with is correct?
I understand that bulk charge is constant current, equalize/boost is constant voltage, there is no equalization/float in Lithium, and no boost duration either.
LiPo batteries are constant current until it gets to 4.2V, then constant voltage until the current drops off to 0.
Sounds like Boost voltage is 4.2V then, but I'm not sure what a cutoff would be...
High Voltage Disconnect Definitely 25.2V
Equalization Voltage Appears to be N/A, because it's not lead, but I think the app requires a value for user-defined, so I'm not sure what to enter.
Boost Voltage I don't know what to do with this one?
Float Voltage Appears to be N/A, because it's not lead, same thing about requiring a value
Boost Return Voltage I don't know what to do with this one?
Low Voltage Reconnect Looks like 18.6V?
Under Voltage Warning Probably 18.3V?
Low Voltage Disconnect Definitely 18V
Discharging Limit Voltage I guess 15V?
Equalization Duration Appears to be N/A, because it's not lead, as above
Boost Duration Appears to be N/A, because it's not lead, as above
Any suggestions would be appreciated!
Thank you,
Chris
