Charging setup for e-bike

[trianglesquarecircle]

Hey all,

Would love to get your thoughts on a power setup for an e-bike, small fridge, and gadgets.

At most I will ride the e-bike once per day. I'll use the stock 110v e-bike charger, which draws 2.5A and completes a full charge in 2.5 hours.

I can fit as much as 400W of rooftop solar.

The turnkey battery route would be a Yeti 1500X, but we do a lot of driving so I would rather have a system that ties into the car's alternator (Jeep Wrangler).

So therefore I'm thinking of doing:

• 100AH LiFePO4 battery
• Victron 100 | 20 solar charge controller
• Victron 24 | 24 DC/DC charger
• 600W pure sine wave inverter

If my math is right, I think the LiFePO4 could fully charge my e-bike 2-3 times without solar input. With solar, the panels should replenish an e-bike charge in a few hours. Hopefully, I've left enough overhead for the other stuff we'd want to use.

Most importantly, with the DC/DC charger, we're adding power while driving.

What do yall think?

See my answer at ExpeditionPortal post. All looks decent except your jeep is 12v, your battery is 12v, you need a victron 12 12 30 non isolated, not a 24 24. Also, the 600w inverter is super wimpy, but ok size for just 100Ah 12v battery, if thats all the ac you need.

lol, replied over there. Thanks, I owe ya!

I charge mine over night. I have a 1000w inverter, 100 amp battery and 200 watt solar. I forget the specs on my bike battery

Awesome! Do you have dc/dc charging as well?

Been too lazy to build one otherwise I would be. For me it would be 12-48. I don't like needing the inverter. Every piece of gear I buy is either 12v or USB. If I didn't have the bike, I wouldn't have bought the inverter.

Same boat here, bike is the only AC gear. Worth it, hopefully

Here is my Setup, which I did optimize over the years:

3x Solarpanels on the roof for my AGM Batterys
Ecoflow River Mini as the 220v Inverter (300/600W) for eBike, Battery-Aircompressor, electric Mini-Chainsaw Battery, AND 100W USB-C for Notebook, Tablet, Drone, Phone
Charging the Ecoflow River Mini by 12v inside of my car by 85W from the AGM`s

At the beginning I had a mich bigger Ecoflow River Pro, but for my purpose the smaller unit was still good enough, much smaller and more lightweigt. From my Solar / AGM Setup there was still enough juice for fridge, 12v Water heater, lights and so on.

I did wrote some reviews who are linked too above. Please note that I own that stuff since a while, some of the grear is replaced with newer Versions or isnt available anymore...

That battery is super small, only 200wh compared to my 700wh ebike. You must be relying on a steady supply of solar, how much solar do you have?

I have 345 Watt of Solar on the roof of my car.

You can choose the bigger size of battery`s.

Some time ago I did a comparison of some common of such battery brands:

They are not so much bigger and under 10kg... Please note: you can too charge those boxes directly by solar too...

Does it look like this?


I have a Levo Turbo and an Aventon Aventure2.

I like the Aventon but its too much of a street orientated bike. What I do like is it will go 30mph pedaling and 22 mph on the throttle. Odds are I'm going to sell it. I like the Levo much more.

On the Levo, 1st gear was too low for me and second wasn't much better. I went up (i think) three teeth on the front gear. That made the gear ratio better for me. I also unlocked the speed cap but about 25 mph on street is about it. If I pedal faster I can hit 28.
Due to an injury I haven't ridden this winter. I'm starting back probably next week.

BTW. What part of LA you in?
