WHY IT'S PERFECT FOR YOU

When you're deep into a job and don't want to stop for a battery swap, the extra capacity of the 4.0Ah pack makes the difference. It runs roughly twice as long as a 2.0Ah battery on the same tool, so you stay productive longer between charges.

The integrated BMS manages charging and discharging to protect cell health over time, TES keeps the battery cooler under sustained use, and Cell Guard protects against knocks and vibration on site. A 5-LED indicator shows remaining charge at a glance, and a full charge takes 120 minutes.

There's no need to fully discharge it first — the battery is designed to be topped up at any time without memory effect affecting its performance.
