GoPro Hero 4, 3/3+ Extended Battery Pack- Limefuel Epic

$84,812

We created each battery in the Limefuel Epic Series to be the only GoPro batteries you need. At 3800mAh for the L38G4 and 5200mAh for the L52G3, the Epic series will power your Hero 4, Hero 3 and Hero 3+ for up to 8 hours* on a single charge! Our batteries are patents pending. 

Each battery in the Epic Series is simple to use. The L38G4 and L52G3 easily fit into the GoPro battery slot, replacing the original battery and extending battery life. The L38G4 and L52G3 are charged through the GoPro camera via USB, as you would charge the original battery.

The Epic L38G4 and L52G3 will include two waterproof extended back covers (safe to 131'/40M and 197'/60M) to keep both battery and camera secure while filming. As with all Limefuel batteries, the Epic Series is made with high quality components and circuitry providing protection against overcharge, short circuit and over discharge.

The Limefuel Team has a proven track record of quality and timely delivery on past Kickstarter campaigns for the Rugged and Blast external battery packs. 

Filming time depends on the GoPro camera video type and card capacity. Higher quality video requires more power from the battery. We conducted several tests for each of these resolutions and frames per second. These are our results. If you have questions about a specific setting or quality not seen here, ask us and we’ll test it out!

  • Take it to the top, hike a Fourteener and capture it all from first ascent through the final descent

  • Catch an awesome day on the slopes, skiing from first to last chair

  • Paddleboard around an entire island to share the view with others

  • Record a day in the life of your favorite furry pal

  • From diving in to crossing the finish line, get video of a triathlon completion

  • Set up the GoPro as a security cam

On a recent trip to Hawaii, Limefuel CEO, Paul Lin, realized his GoPro camera was not able to fully capture all his adventures due to the low capacity battery. While driving through the beautiful mountains of Maui, he had to keep switching out low capacity GoPro batteries, therefore, missing some epic moments! He also had to carry multiple smaller batteries with him each day and remember to charge them all each night. This is when he decided something needed to be done.

With the Limefuel Epic series, we have set out to develop a high capacity battery solution for GoPro users who desire to capture every moment of their exciting experiences. To begin, we had to find a way to design a battery that would offer high capacity but still have a small footprint, similar in size to the GoPro camera. We needed to add juice without a lot of extra weight or bulk.

Together with our battery manufacturing partners, we tested various battery configurations combining the front piece that fits into the camera with different back pieces until we found an acceptable combination of physical size and capacity. We also accounted for raw material availability so there are no hang ups in manufacturing. The Epic L38G4 and L52G3 are designed to be all battery and allows you to take your camera anywhere, even under water.

Since the Epic series offers more power than the original GoPro battery, we had to design a new, longer, waterproof back housing piece. We rigorously searched to find the best manufacturer to produce quality plastic housings. We then tested and retested samples to be sure they adequately protected the GoPro camera and Epic battery.

After extensive testing of both the Epic batteries and back housing by the Limefuel staff, we believe we have come up with a powerful companion for the GoPro Hero 4, Hero 3 and Hero 3+. After previously completing two successful Kickstarter campaigns for the Limefuel Blast and Rugged, we know we would not be where we are without the amazing support of our backers. Now, we need your support to make this product a reality so we can all capture those Epic moments!

Risks and challenges

-Design and Manufacturing: The raw materials for the Epic series have been pre-procured. This means that our suppliers and manufacturers have ensured us that there will be plenty of parts to manufacture our battery packs. Our materials are of the highest grade, we don't foresee any issues. It is certainly possible for there to be manufacturing delays - a part doesn't fit properly, parts not arriving on time for the assembly line, etc. If any issues arise, we will communicate it with you.

-Fulfillment: Logistic methods and providers have been tried, tested and re-tested during this period.

-Conclusion: During the design, manufacturing and launch of our two prior successful Kickstarters, we learned a great deal about the process of creating and building our products, areas which create concern or delay and how to overcome them. While there can always be unforeseen occurrences, we are confident we can deliver the Epic Series to our customer’s high standard and on schedule.
