Genuine Power Behind Every B2 Mission
The Battery the B2 Was Built Around
This is the genuine BT2-10 standard battery supplied with the Unitree B2 industrial quadruped, rated at 45,000mAh capacity and 2,268Wh of energy at DC 50.4V. It’s sized specifically to match the B2’s payload capacity and multi-hour mission profile, not a generic pack adapted to fit.
The same battery bay and connector are shared with the Unitree B2-W, so this is also a genuine replacement or spare for that platform — useful if your fleet runs both. A -20°C to +50°C discharge range and hot-swappable slide-in design mean field teams can carry a spare and keep a mission going without waiting on a full recharge.
45,000mAh, 2,268Wh
High-capacity power supports the B2’s rated multi-hour walking endurance without frequent recharging.
-20°C to +50°C Discharge Range
Built to keep working through real outdoor conditions, not just controlled indoor demos.
B2 & B2-W Compatible
One battery part number covers both platforms, simplifying spares and fleet maintenance.
Safe, Regulated Charging
A defined 58.8V charging limit and 0°C to +40°C charging window support safe, consistent recharge behavior.
