PowerFilm LightSaver Max

PowerFilm LightSaver Max - a rollable solar lithium battery  

Stats: 

18000 mAh

2x 2.5A USB

12v max 5A

Rollable solar panel

 

Solar charge 6-8 Hours

Wall charge (USB-C) 3 hours

My desired use:

Directly connect the LightSaver Max (LSM) to my Yaesu FT817ND for extended portable Amateur Radio operations, additionally allow charging of my mobile phone, my 7in android tablet used for logging in the field along with assorted miscellaneous charging such as GoPro for recording, my headlamp for night operations etc.

During the day time I would like to see if the, when unrolled and placed in the sun, will the solar panel pass an increased voltage spike along to the radio. Based on the provided specifications from the suppliers, the following use times are calculated:

LSM contains an 18000mAh battery that would allow

Yaesu 817ND

TX      2000mAh       9 hours total transmitting

RX      450mAh        40 hours total receiving

Charging               

iPhone 2900mAh       6 times from 0-100%

Tablet  3450mAh        5 times from 0-100%

Please note these are not combined or simultaneous use calculation but individual single item calculations.

 

Conclusion: as per the video the LSM performed brilliantly. Delivering a smooth quiet 12.2v for over 2 hours of use, plus charged my phone and tablet to get the battery down to 6/10.  

 

 

#ProjectSailBoat - Solar Battery Box pt1

Linked the broader #ProjectSailBoat thinking and dream, the idea of self reliance is big in my mind.

The ability to sit at a mooring for a weekend or more extended coastal sailing while making your own electricity to power marine radios and lighting or more creature comforts like CD players and AM/FM Radios I find extremely exciting. To me simply, solar is magic.

While exploring this broader idea of self reliance I was also exploring solar, power storage and the use of that stored power.

Below is a short clip I made of the basic system, solar panel, solar controller, battery.

In this specific case, it is a 10watt small panel, that throughout the solar controller (whose role is to stop pumping power from the sun into a battery after it is full) then through a small switch (panel isolation) then into a small spot light battery (9ah, 12v)

Narooma: Camping in the rain

2014-03-08 15.58.45

I really needed this weekend!

We had been planning another quick weekend away. This time it was more a car camping trip to test out our larger, cheaper car or festival tent the Shoalhaven V4 by Spinifex from Anaconda for only $99.

For the price this tent took a battering this weekend. At least 6 hours of solid rain. At one stage I woke up in the middle of the night to find the ground so soaked that the water was simply pooling. 

Not a single drop inside the tent. The only downside is the super cheap pegs.




The ventilation and double door (one within the veranda and one from the opposite side) along with the full body mesh, other than the tub floor, make is perfect for our yearly trip to Tropical Fruits in the hot steamy NSW North Coast hinterland of Lismore. With the waterproof fly fitted it withstood the nights rain.

Another highlight of the weekend was seeing a poor lost lonesome penguin nesting in a tiny sea cave.

The weekend was a great chance to test out a new little toy I picked up a few months ago from Goal Zero. Their USB powered LED “Luna”. A really versatile little light that was perfect for lighting the whole tent.
