16" 42V Brushless Cordless Chainsaw — Dual Battery (2 x 5.0Ah) with Charger, Tool-Free Tensioner & Instant-Stop Chain Brake for Tree & Wood Cutting

Compact 16" cordless chainsaw kit powered by a 42V brushless system and supplied with 2 x 5000mAh large-capacity batteries and a charger. The dual-charging outlet extends runtime so you can complete jobs with fewer battery swaps, and an LED battery indicator plus individual battery level buttons let you check each pack’s charge at any time. Battery safety features include max 75A discharge overcurrent protection, max 70°C discharge high temperature protection, and max 230A short-circuit protection current to give added confidence when using the cordless/rechargeable battery units. Practical user features include a tool-free chain tensioner and an instant-stop chain brake for quick adjustments and safer operation. An automatic oiler keeps the chain continuously lubricated to reduce wear and downtime; for top handle chainsaw use add the corresponding lubricating oil to the tank based on working time — for one hour of operation it is recommended to add 2-3 scale of lubricating oil, and avoid overfilling to prevent leakage.
