Developed with Popular YouTuber “Satoshi’s Hobby Room” Over Two Years
“Satoshi’s Hobby Room” is a popular YouTube channel highly trusted by users considering compatible batteries. The channel is recognized for its thorough verification style, which involves actually using, testing, and even disassembling genuine and compatible Makita power tools and batteries.

Satoshi collaborated with Shade Inc. for approximately two years to create a truly usable compatible battery from a user’s perspective. This product was finalized after repeated verifications with Waitley’s technical department. It is presented as a product genuinely developed by a verifier with deep knowledge of compatible batteries, rather than merely a celebrity endorsement. A video titled “【超必見】遂にバランス充電機能搭載!「サトシの趣味部屋」コラボの究極のマキタ互換バッテリー「BALANCE CORE」爆誕!!” is also available on his channel: https://www.youtube.com/watch?v=Wa0-izt3ZXs
Key Product Features
1. Balance Charging Function — A Feature Not Found in Genuine Batteries
This function addresses the primary cause of compatible battery failure: cell imbalance. It automatically corrects voltage differences between cells by discharging higher-voltage cells using a 10Ω bypass resistor. This feature, not present in genuine Makita batteries, contributes to extended battery lifespan.

2. PD65W USB Type-C Input/Output Support
The battery supports PD65W rapid charging, eliminating the need for a dedicated charger. Conversely, it can also function as a large mobile power source to charge smartphones, tablets, and laptop PCs, making it suitable for job sites, car camping, camping, and disaster preparedness.

3. Low Voltage Cutoff Function
The battery features an automatic cutoff at 2.5V per cell or 12.5V for the entire pack. This prevents over-discharge issues, which are common in compatible batteries.

4. High Output: Rated 40A, Peak 100A
This 18V 6.0Ah (108Wh) battery utilizes SUNPOWER INR18650-3000mAh cells, providing stable power even for high-load tools.

5. Strict Quality Control
The battery undergoes rigorous cell selection at the factory and has passed functional and safety inspections by a domestic third-party organization.


“VOLT LAB” — Shade’s New Battery Brand Pursuing Functions and Quality Beyond Genuine Products
“VOLT LAB” is a new brand for power tool batteries launched by Shade Inc., known for its “AERO TOOLS” series of powerful electric blowers. The brand’s concept is to pursue functions and quality that surpass genuine batteries, rather than simply offering lower prices. By developing products with features not found in genuine batteries and aiming for superior quality and performance, VOLT LAB seeks to fundamentally change the perception of “compatible = cheap and low quality” and deliver next-generation batteries that users truly want to use. The “BALANCE CORE 18V 6.0Ah” is the first flagship model embodying this vision.
