The FPV-POWER 17.5Ah battery suits kayak fisherman who run larger fishfinders/GPS which typically draw more than 1A. If drawing 1A, you can expect around 17 hours of use but you may need a voltage regulator as some fishfinders need a minimum of 11V to run.
Our FPV-POWER kayak battery packs are designed to be simple to use, easy to maintain and come with a one year warranty . However, there are a few things that need to be done to prolong the life of your battery.
Keep your battery charged – Not only will this mean that your battery will be ready for your next outing, but it will keep your battery in tip top condition.
Store in a cool dry place.
Keep the contacts/connections clean – Dirt and salt will not only corrode but can compromise the waterproofness of the seal.
Mount the battery off the bottom of the kayak – This will help both the battery and connections stay dry and clean.
Mount the battery securely to make sure that it does not get knocked around while in transport or in use.
Do not leave your battery flat for long term storage – The Battery Management System (BMS) will auto cut when the battery hits a safe low voltage. However if left in this state for a prolonged period of time, you can permanently damage the cells. Do not use to power items which draw more than the rated 6A . – Doing so can cause battery failure and fire.If unsure, contact us for more information. Do not open or modify the battery pack in anyway – Opening the sealed case will immediately void your warranty. Do not leave a charging battery unattended. Do not charge on or near flammable objects. Do not drop the battery pack – Batteries are fragile objects and any hard knocks can damage the cells. Damage to the case such as cracks will void your warranty. Do not leave the battery in the kayak during transport. Do not submerge the battery for longer than one hour as per the IP67 rating.
Installation Your battery pack will come with a pigtail that will have two exposed wires on one end and a female waterproof jack connection on the other. Note that the brown wire is positive and the blue wire is negative. The best way to connect the lead to your sounder is by soldering the wires together and sealing the join with silicon before covering with heatshrink. The next best option is to use crimps however they are harder to waterproof. You do not need a fuse for the battery as the built in Battery Management System will automatically cut out if there is a short but you will still need to have an inline fuse on your sounder side.
Charging with standard 2A Charger
1. Plug the supplied 2A charger into the wall and check that there is a green light on the charger. 2. Plug the battery into the charger. The light on the charger will turn red. 3. Once charging is completed, the light will turn green. You cannot over charge our batteries as there is an automatic cutoff.
