Two used but great condition Anton Bauer Titon Batteries. Both batteries are Gold Mount (AB Mount).
Titon 150 SL - (Purchased 2021)
Titon 90 - (Purchased 2020)
Both still have great runtime. I have not perceived any drop off in power delivery.
The included 2722 Charger has had the firmware updated to 3.6 to support the Titon batteries.
