Longer Battery Life

When powered by our 12V 50ah battery, the tractor can easily glide and maneuver all day long. And don't forget our Diypow Bluetooth app, which makes it easier than ever to keep track of the life of your LiPo battery. All this from your smartphone!

The Diypow 12V 50Ah Li-Ion deep cycle battery is one of the most advanced Li-Ion deep cycle batteries on the market. It also comes with an impressive 10-year battery warranty to ensure your satisfaction and peace of mind. We are in it for the long haul.

Reliable BMS System

The 12V 50Ah lithium battery is ideal for deep cycle systems. All our Diypowd batteries are available with a Battery Management System (BMS). Ever heard of a smart battery? This is it! Our advanced system monitors key operating parameters such as voltage, current and internal temperature. These functions are essential for safe charging and discharging. Let our LiPo batteries go further with you, last longer and enjoy your fishing time.

Need to connect more than one battery? No problem! Ion deep cycle batteries can be connected in series (up to four) or in parallel, as many as you need.

Auto-balancing Function

Due to the upgraded auto-balancing function, you can combine batteries in parallel more safely. We recommend connecting the batteries with appropriate cables to achieve optimal effect. Please note that do not connect batteries in series, and the maximum number that can connect in parallel is 8.

Bluetooth Monitors Battery

Bluetooth 5.0 is designed to reduce the energy consumption of Bluetooth peripherals. It is faster and operates over longer distances than older versions. You can easily monitor the status of your battery more accurately and conveniently in real time.

Low-Temperature Self-Heating Function The intelligent self-heating function will start operating automatically once the battery’s core temperature drops below 41°F (5°C), effortlessly keeping your battery charged in cold environments. Plus, this function is powered by the Charger/Controller's current instead of the battery itself.

Maintenance free

Lithium-ion batteries last two to four times longer than lead-acid batteries. Frequently having to maintain your lead-acid batteries can be time-consuming and costly. However, Diypow lithium-ion batteries are virtually maintenance-free and do not require frequent watering, equalization charging, or cleaning.

10 Years Warranty

On average, our 12V 50Ah battery lasts between 3000 and 5000 cycles. This equates to approximately 10 years of battery use. The cycles are the number of times your battery is fully charged and then discharged.

Wide Applications for 12V 50Ah LiFePO4 Battery

Looking for a very lightweight battery? Our 12V 50Ah batteries could well be the perfect answer for you! If you want to propel a small boat or fishing kayak (up to 50hp), many of our customers buy two or three 12V 50Ah tractor batteries to get the job done.

Are you a fan of solar systems? In addition to your trolling motor it can also be a very suitable mini solar system setup for small commercial equipment and much more.
