Ra was designed to be versatile so you can use it for a variety of applications. We provide three accessories to aid in mounting Ra to best fit your needs. Hikers and hunters might fasten it to their shoulder straps. Skiers choose to mount it on both their chest and legs. Runners prefer to attach it on their running vest chest strap or running belt.
In this video, Ben Light demonstrates some options for mounting RA to your running gear.
In this video, Craig Lloyd from Trail and Ultra Running does a review of the Kogalla products and shows his favorite mounting methods.
Providing this much light requires a lot of energy. Your choice of BatPak comes down to two factors. How much light do you want or need, and how long do you need it? More light and longer run times require more energy and hence a larger BatPak. So we offer three sizes of BatPaks.
In this video, Ben Light introduces the various components supporting the RA light including the three BatPaks.
The RA light has 20 levels of brightness so you can manage your power consumption to meet your needs. This table lists how long the batteries will last starting from a full charge. The numbers are for a single RA at a corresponding brightness. To get battery life for two RA running at the same brightness, divide the number of hours by two.

To keep it simple, we sized the BatPaks with their total energy corresponding to their model number. The BatPak 2 lasts twice as long as the BatPak 1 and then of course the BatPak 3 lasts 3 times as long as the BatPak 1.

Charge times depend primarily on three factors. The first is battery size. The more energy a battery holds, the longer it takes to charge. The second is charger current. Common USB charger currents are 500 mA, 1 Amp and 2.1 Amps. The BatPaks can be charged with most standard chargers and can charge using up to 2.1 Amps. The third is how depleted the battery is. The following times are for a fully depleted battery.
|Charge Current||BatPak 1||BatPak 2||BatPak3|
|2.1 Amps||3 Hours||6 Hours||11 Hours|
|1 Amp||6 Hours||11 Hours||23 Hours|
|500 mA||9 Hours||17 Hours||34 Hours|
If, for instance, a battery is only half depleted, the charge times will be roughly half of the above values.
The Kogalla BatPak is designed to power the Ra Adventure Light. It uses Lithium-ion battery cells which are rechargeable, high energy density, low maintenance and reliable. They should last 300-500 charge cycles or 2-3 years and with proper care may last much longer. It’s not as though they stop working but rather the capacity diminishes. The factors affecting the capacity and battery life include charge cycles, temperature and storage. Let’s review these in more detail.
A charge cycle is defined as charging and discharging with the variable of depth of discharge. Unlike nickel-cadmium and nickel-metal hydride batteries which develop a capacity memory when partially charged/discharged, lithium ion batteries actually prefer partial discharges. In fact, it is best to avoid fully discharging the battery frequently. That is referred to as deep cycling. Each cycle wears down a battery a small amount. Deep cycling decreases the life of the battery at a faster rate than partial cycling. It’s better to charge more often than to fully discharge.
Extreme temperatures are hard on your battery. Ideally you would always use your battery at room temperature. At 73 F your battery should retain over 90% capacity up to 500 cycles. But that’s not practical and the BatPak is intended to be used outdoors.
The specification for charging temperature is 32 F to 113 F. It will perform well at the higher temperatures but the internal resistance of batteries rises when cold which prolongs the charge times. And the extreme temperatures when charging will negatively affect the battery life. For best results and longevity, you should keep your charging temperature in the range of 50 F to 86 F.
NEVER CHARGE THE BATPAK BELOW FREEZING. Charging below 32 F will damage the battery.
The discharge temperature is more liberal at -4 F to 140 F. That’s good news if you’re using it outdoors. As with discharging, extreme temperatures will impact performance. The lower temperatures will reduce the capacity and thus run time when powering Ra. While the BatPak will perform well at the higher temperatures, it reduces the battery longevity. To maximize the battery life and performance, the same moderate temp range of 50 F to 86 F is best.
Proper storage of the BatPak will maximize its longevity. Do not store your BatPak while fully discharged. When you have depleted the charge, restore it partially as soon as possible. Storing a fully depleted battery will shorten its life and if stored long enough, will prevent you from waking it up. It’s recommended that you store your battery at about 40-50% of capacity.
Store the BatPak at moderate temperatures (50F to 86F). It’s especially important to avoid storing at high temperatures for prolonged periods.
To review, never charge your BatPak below freezing and don’t store it fully depleted of a charge. If you care for your BatPak as outlined here, you should get 300-500 cycles before the capacity drops below 80% which will likely be about 2-3 years. It should last longer, however, the capacity will continue to drop over time and cycles to where it eventually becomes more practical to replace it.
Ra is waterproof but the BatPak is not. Ra is rated IPX7 which means it can be submerged in water up to one meter for 30 minutes. The USB ports on the BatPaks are vulnerable to water. If enough water gets into the ports then the BatPak will shut off.
Ra is exposed to the elements so being waterproof is a good thing. Typically the BatPak is stowed in a pocket, pouch or pack and somewhat protected from water exposure. If you stow the BatPak with the ports pointed sideways or downward, it will minimize the potential for water to drain into it. If your BatPak fills with water to the point it shuts off, drain the water and fully dry out the BatPak. Then you can turn it back on. However, we recommend you avoid that scenario by protecting your BatPak from water.
