![]() Why Lithium?Īfter some searching around i decided to buy an Aliant YLP Ultralight Lithium Iron Phosphate (LIFePo4) Battery. Housing a battery within a waterproof box will further prevent the possibility of short circuiting a lithium battery on a kayak. A good quality charger will prevent overcharging. Luckily high-quality modern lithium batteries come in robust sealed housings and have integrated fail-safe features to minimise the risk of battery failure. Overcharging or short circuiting a lithium battery must therefore be avoided at all costs. Short circuiting can occur when the battery is wet, particularly in saltwater, and this is a realistic possibility within the confines of a kayak. In this scenario the battery starts to pump current back into itself almost unrestricted and with no where for the current to go it will rapidly heat up leading to failure and combustion of the lithium cells. Short Circuiting - this is where current is allowed to travel between the positive and negative terminals of the battery through a low-resistance conductor.Overcharging- if the battery is continually charged then the excess charge will have no where to go and dissipate as heat, potentially leading to failure and combustion of the lithium cells within the battery.not a good scenario on a kayak! There are two main ways you can overheat a lithium battery: Lithium batteries can also be potentially dangerous with a risk of fire or explosion if overheated. The price of these alone puts many off using these batteries for kayak fishing applications. Lithium batteries are expensive and require a specialist charger to safely charge the lithium cells. ![]() Whilst having several advantages, Lithium batteries do have some disadvantages. So why are they not widely used on fishing kayaks? Safety Concerns and Disadvantages of Lithium Batteries they are lightweight and they hold a lot of charge for their size. ![]() There are several types of Lithium batteries available, including Lithium Polymer (LiPo) and Lithium-Ion (Li-Ion). Lithium batteries are great. Your phone will have one, so will your laptop and various other mobile devices. Lithium-based batteries are used widely in modern electronics. It is a highly reactive alkali metal with a wide number of applications including use in rechargeable battery cells. Not only is Lithium a great song by grunge rockers Nirvana, it is also number 3 on the periodic table of elements. This may not sound a lot but when you have to manually haul your fully-laden fishing kayak to and from the water to your vehicle, often several hundreds yards away or involving steep slipways or paths, then every 1kg of weight is very noticeable!! I built a waterproof battery box using this battery and in total it weighs in at exactly 1.825kg. It was inexpensive at around £20-25, but it is heavy. My 12V 7Ah Sealed Lead Acid (SLA) battery has served me well over the last 5 years.
