Charging my 48v eBike battery

[eStilo]

Hello, im very green to solar panels and want to charge my ebike battery via solar panels
Im renting a room at the moment so i need portability i want to fit this in my Honda Civic Touring and go camping or trail ridding. Can this system work for me i want to charge straight to the battery (not when ridding) if not what do i need. Ive seen your videos on YouTube and found my way here. I contacted Renogy with this question but no response

Renogy 200 Watt Off Grid Portable Foldable Solar Panel Suitcase Built-in Kickstand with Waterproof 20A Charger Controller, 200W-Waterproof​

Rad Rover 5 battery info:
48V, 14 Ah (672 Wh) with Lithium NMC Samsung 35E cells, rated for 800 charge cycles

Wall Charger:
100-240V and 50-60Hz input compatible for worldwide use and has a standard North American 3-prong plug.
unsure if i need to use it I would like to just connect solar panels straight to the battery (dc to dc) for charging without inverter.

Thank you, your experience and knowledge will be appreciated

Welcome to the Forums!

I don't know enough about the components of your system, but you'd need an inverter to power the wall charger. Ideally, you'd want to go from the MPPT built into the panel directly into the battery (and skip the charger); but for that to work the voltages and charging characteristics need to line up (that is the MPPT would need to output 48V to match the battery and be adjustable for the battery chemistry). As the battery is Li-NMC you might be better off adding an inverter as those are the ones that catch fire so you want a safe charging solution. Depends on the Renogy MPPT capabilities.

I'll move this to the vehicle section in case anyone knows about that panel/battery or can provide better advice.

You can use the Genasun GVB-8 Boost to charge directly from a lower voltage solar panel, the renogy panel should work if you bypass the included charge controller.

The cheaper but less quality option is these MPPT-7210A boost chargers that are on various sites, programmable which is nice, but do have a fan and not the highest quality build, and not the most efficient.

Your battery looks like it uses a standard barrel power jack, easy to find a connector for that.
