Bronson MBL Pro Series - The Trolling Motor Battery

The all-new Bronson MBL Pro Series trolling motor battery is a premium deep cycle lithium battery built to deliver unmatched power and efficiency at a great value. Using safe, lightweight LiFePO₄ chemistry, it keeps kayaks, bass boats and pontoons running strong all day—without the weight and maintenance of lead-acid packs.

Protected by shock-absorbing EVA foam inside an IP67 dust- and waterproof case, this compact powerhouse offers high energy density in a grab-and-go form. A non-slip rubber handle and plug-in waterproof connectors make installing your trolling motor battery quick and fool-proof—even on a wet deck.

An intelligent Battery Management System actively balances cells while guarding against short circuit, overload and over-voltage. That means a deep cycle lithium battery that retains its original capacity for at least 3 000 cycles and can last well over a decade.
