Frequently asked questions
Here are some common questions about our batteries, if you have other questions contact us.
Choosing the right battery depends on your motor size, voltage, and usage time:
-
MBL-60Pro (60Ah) 12V
Suitable for small boats, kayaks, and low-power motors.
Approx. 3–6 hours runtime depending on speed. -
MBL-100Pro (100Ah) 12V
Ideal for most trolling motors and full-day use.
Approx. 6–10 hours runtime under typical conditions. -
MBL-240Pro (240Ah) 24V
Designed for extended trips and high-thrust motors.
Approx. 10+ hours runtime for demanding use.
Yes, lithium batteries are a direct upgrade for lead-acid batteries in most trolling motor setups.
Benefits include:
- Up to 70% lighter weight.
- Faster charging times.
- More usable capacity (o voltage drop).
- A more sustainable choice, with a longer lifespan and fewer replacements compared to lead-acid batteries.
Make sure your charger is compatible with LiFePO4 technology for optimal performance.
Depending on the model:
- The MBL-60 Pro charges fully in around 3 hours.
- The MBL-100 Pro and MBL-2400 Pro both take around 5 hours.
Your battery ships at around 40% charge, so make sure to give it a full charge before your first trip.
These batteries are built with water-resistant or waterproof housings (e.g. IP67-rated).
This means:
- Protection against rain, splashes, and temporary immersion
- Suitable for boats, kayaks, and outdoor environments
However, they are not intended for prolonged submersion underwater.
Yes. Every MBL Pro battery has a 100W USB-C port, so you can charge phones, fish finders, GPS units or any other USB-powered gear at the same time as running your motor.
Connection is via a waterproof WP80 plug. It's self-locking so it won't accidentally disconnect on the water. Installation only takes a few minutes using a size 3 Allen key. Purchase it directly from us here.
