Where Can I Buy A Solar Battery Charger

What Do You Need To Charge An E

Solar Battery Charger (LiPo/Li-Ion) || DIY or Buy

My preferred solar charging setup for an ebike using standard charger

Unfortunately, you cannot simply buy solar panels, attach them to the battery of your eBike, and sit around waiting for your battery to charge.

Solar panel chargers are operated with a set-up, which assists with the collection, transfer, and output of reversed energy to the battery, among other things.

To make your own charger, addition to the panels, you will need a charge controller, which boosts the amount of output power obtained from the solar array.

The problem is the battery voltage, which as we know is between 24 volts to 48 volt normally.

A standard 100 watt solar panel has an open circuit voltage of about 22V, which reduces considerably when hooked up to a load.

You would need at least 3 of these connected in series to produce enough volts to charge a 36 volt ebike battery, for example.

If youre building your own solar electric bike charger or looking to buy solar chargers, keep this in mind as you consider your options. It get complicated.

I prefer to use the standard eBike battery charger operating on alternating current, and use an inverter to feed it. Its the simplest solution.

Q: How Do Solar Maintainers Work

A: Just like any other solar device, a solar battery maintainer converts energy from the sun into electricity. Then it either supplies batteries with the necessary power or cuts the power off completely to avoid overcharging. If you have a flat battery, a maintainer will pass more power to it to keep it alive. On the other hand, it will cut off the power for fully charged batteries to prevent damage due to overcharging.

At the sunniest point of our tests, the BigBlue tied with the X-Dragon 20W SunPower Solar Charger for how much power it produced at any one instant, reaching about 10.7 watts. But over the course of the day, the BigBlue had the highest cumulative wattage: 48.8 watt-hours to the X-Dragons 43.7 watt-hours. That isnt a huge gainyou could barely charge an iPhone X battery halfway with the additional powerbut every watt matters if youre far from an outlet, and the extra power costs little more in size or price.

The BigBlue stood out among the dozens of models we considered in part because it has two 2.4 A ports and one 1 A port so you can charge three devices simultaneously. Every other model we tested had just two ports. Plus, the ports on the BigBlue are the most protected from water and dust among all the models we tested, as theyre covered by both a cloth flap and a rubber cover. Thankfully the cover is connected by a small tether so you dont lose it.

How Do I Charge My Solar Batteries Fast

The charging speed of the batteries depends on two factors, and one is the max capacity of the batteries to transfer the energy from the power source to the main component.

Another factor is the voltage. When your battery is charged at the max voltage for few hours, the batteries will quickly charge.

The solar batteries would not be possible to charge at the max capacity under direct sunlight due to a consistent shift in the energy received from the sun.

Even during the afternoon, the sun rays are blocked by the cloud, which reduces the efficiency of the solar batteries.

An alternative solution is to connect the batteries to the power grid. Some solar power batteries come with the duel charging facility.
