The Challenge

The fascia gun is one of the best-selling products of RH Sports Equipment. This fascia gun has a built-in rechargeable lithium battery. Due to reasons such as large battery voltage drop and high static electricity from early battery suppliers, it is easy to cause the fascia gun to be too weak.

In terms of battery weight, the batteries of other lithium battery manufacturers are heavy, making it inconvenient for customers to use the fascia gun.

In addition, other battery manufacturers were unable to meet RH’s needs in terms of battery design. In the end, RH chose to cooperate with Ufine Battery, which has many years of experience in lithium battery R&D and production, to solve these challenges.

Finding A Solution

After Ufine received the customer’s product, it first conducted a cause analysis, found the cause, and found a solution step by step.

1. The normal discharge of the battery from the previous battery supplier cannot meet the output power of the fascia gun, causing the fascia gun to not work properly.

After analyzing the reasons, Ufine adopted a rate-type discharge material system to improve the discharge coefficient of the battery. This meets the power demand of the fascia gun so that the fascia gun can work strongly and the massage effect becomes better.

2. Given the problem the weight of the fascia gun is also heavy due to the heavy weight of the battery, and the customer experience is not good. Ufine uses a high-energy density solution. Using a high-rate nickel 811 system, the energy density reaches 253wh/Kg. This way, the overall battery weight can be reduced. The fascia gun is also lighter than before.

3. The batteries provided by RH’s previous battery supplier had high static electricity. In response to this problem, Ufine’s Pack engineers optimized the circuit design and replaced the protection IC. This reduces the impact of static electricity on the IC, thereby reducing the problem that the fascia gun can not work properly due to high static electricity.
