Is this the best deep cycle battery for a trolling motor? Let’s find out.
Even the most novice fisherman knows that controlling and mastering your boat to wherever is the best location to catch those elusive fish is essential. You don’t want to get stuck in the middle of the ocean with your trolling battery letting you down. Days may pass before rescue appears when that happens. The right trolling motor with the right parts attached to your boat may mean the difference between that successful and not so successful catch.
Trolling motors are that electric motors designed with a propeller and shaft attached at the end of your boat. Typically, they are fastened either to the front (bow) or at the back (stern) of the vessel controlled by a swivel mount. Trolling motors are separate from the outboard engine of your watercraft; a separate marine battery powers them.
A dose of caution, though, regular car batteries cannot deliver and maintain the power supply that a deep cycle battery provides. It will likely damage the trolling motor and destroy the vehicle battery, too. Each trolling motor specifies an amount of thrust power in either 12, 24, or 36-volt versions. Voltage and thrust power have a direct relationship, the higher the voltage, the higher the power of thrust a motor provides.
Before we delve further into the characteristics of a deep cycle battery, let us first take a look at the amount of thrust power you need for your boat. Thrust power is measured in pounds of thrust. The weight of your boat is the first thing that you need to consider when choosing how much thrust power you will want to have. However, the overall weight of your watercraft is inconsistent. Things like bringing an extra buddy, extra gear, coolers and other things in fishing expedition matters. Also, the weather conditions such as water current and wind may call for greater pounds of thrust. When it comes to propulsion power per weight ratio of your boat, the rule of thumb is five pounds of thrust per every two hundred pounds of a fully loaded watercraft. It is then imperative to have some batteries on hand, in the case of emergency, or move up in motor voltage.
Before we delve further into finding the best trolling motor battery, it is important to get acquainted with the general terminologies encountered with regards to your deep cycle batteries.
-V means volts or voltage.
-Ah or Ampere hour is the battery’s capacity in amps per hour before they will drain.
-AGM or Absorbed Glass Matt is used for the stabilization of your plate in advanced batteries.
-SLA or Sealed Lead Acid is the corrosive liquid found inside the batteries.
Vmaxtanks MR107 12V 85Ah AGM SLA Deep Cycle Battery Product Review
This deep cycle battery has an 8mm HEX screw in terminal included in the package. It’s 12V 85Ah Marine SLA AGM is a heavy duty trolling motor battery with 10.2 inches in length x 6.6 inches in width x 8.3 inches in height. The battery’s float service life spans up to eight years. Vmaxtanks MR107 has a lead-tin alloy that provides an additional margin of performance and float service life span, even after repeated discharges. VMAX tanks utilize an AGM electrolyte suspension system of a high porosity that contains and absorbs the electrolytes. Other contaminants like silica gel are not used. Specific gravity checking of the electrolyte will not be required, no provision for this type of maintenance is demanded.
A VMAX BC1215 12V 15Amp 7-Stage Charger is needed for your Vmaxtanks MR107 deep cycle battery. It is more pricey than the other trolling motor battery in its category, but performance-wise, you will get more value for your money.
The best thing about this battery is the real deep cycling feature and ability at a price that is at par with the performance it gives. The high porosity AGM electrolyte suspension system completely absorbs pure electrolyte with no silica contaminations which provides enhanced efficiency. The smooth work in the sealing is tested that no risk of leak or spill is anticipated and can be mounted without any physical or functional damage.
However, one major drawback of the product is that the battery can only be applied for deep cycle purpose and when it is used to cranking the battery’s functionality, reduction od service life may occur. It is good only for thirty- to fifty-five-pound trolling motors and might not work for heavier ones and too much power for motors with lighter weight. VMAX 857 is recommended for lighter trolling motors and Vmaxtanks MR137 for a heavier one.
Vmaxtanks MR107 is a battery guaranteed not to disappoint, whether you are a professional or marine hobbyist. The battery’s high quality and robust performance are recommended for your deep cycle marine battery needs.
