DMX/MMX High Power Solar Battery System
USA SHIPPING ONLY!*
The High Power Solar Battery System
The High Power Solar Battery System includes the following items:
1. A compact, 4 panel 11 watt solar panel with >22% efficiency for full 5V 2A USB 2.0 charging power. This is a very nice, compact unit that feels like a small book when folded up. This is the most compact design for charging just one device at a time, or two devices at a slower rate.
2. Our Solar Battery, a 20 Amp-Hour battery with a great flashlight and a compass built in. This is a very powerful battery, only 29% less power than our Super Power Solar Battery System.
3. A 5V to 12V cable to power your MMX or DMX from the battery bank
4. A USB A female to C cable to connect the solar panel to the battery for charging at the maximum rate.
Our Super Power Solar Battery System provides additional features and more power.
About Amp-Hours
Batteries based on multi-cell Li-Ion batteries are normally rated at the voltage of a single cell, typically 3.6 volts. This is true of this battery, as well. However, there is a power conversion circuit to up the voltage to 5V for the USB outputs. Because of the higher voltage and the loss of energy in the conversion process, typical output at 5 volts is around 12 - 13 Amp-Hours, and at 12V, after being converted a second time, is about 4.8 - 5,0 Anp-Hours. Compare this to. typical Gel Cell 12V battery, rated at 7 Amp-Hours. Sounds like the Gel Cell - at 3x the weight - wins, right? WRONG, because you are not supposed to discharge the Gel Cell more than 50% of charge - that is, only 3.5 Amp-Hours! So this High Power battery, which has over 4.8 Amp-Hours of actual usable power, is significantly better, and ⅓ the weight and size.
In addition, all of the components can be packed into the included zipper canvas bag, shown in the image. Weight is less than 2 lbs!
Performance
The total package provides all you need to power your MMX or DMX off grid, either for a short period, or for an extended period. Your MMX or DMX will operate in receive mode for over 30 hours from a fully charged battery without recharging. A typical usage pattern allows you to operate continuously for 8 hours a day both transmit and receive on only 2 hours of sun per day. A complete battery recharge takes about 6-7 hours of sun.
IMPORTANT: The 5V to 12V cable that connects your MMX or DMX to the battery provides 12V with current limited. This prevents damage to your PA (power amplifier) when under stress from high SWR. This is a very valuable safety feature.
*Batteries cannot be shipped internationally. You can request a refund via PayPal after you receive your product for the cost of the batteries in that case.
