![]() ![]() In fact, Li-Ion battery has been popular in RC fixed wings / planes as they normally only use one motor. If you use an efficient power system, Li-Ion cells can totally handle it. If you power an FPV freestyle drone with Li-ion, it will feel very weak and slow.įor long range aircraft however, it’s a great option because they don’t require a lot of current. However, the maximum discharge rate of Li-Ion battery is not great compared to LiPo, that’s why it’s not a popular battery choice for FPV drones. On paper you should get double the flight time! The 4S 18650 3400mAh I built, only weighs 203g, while a 4S 1600mAh LiPo has nearly the same weight. Li-Ion battery has higher capacity than LiPo for the same weight. The Pros and Cons of Flying Li-Ion Battery Both battery types can be fully charged to 4.2V per cell. Lastly, you can usually discharge a LiPo down to 3.5V per cell safely, however Li-ion can go much lower, e.g. To give you an idea, typically a high quality LiPo have around 30C to 40C of continuous discharge rate, while Li-ion only has 5C ( What’s C rating?) LiPo batteries have much higher discharge rate than Li-ion, meaning you can get much higher current out of them. The PWM can work with a 24 v battery and motor combo as long as the amp draw stays under 50A.Left: LiPo 4S 1500mAh Right: Li-ion 4S 3000mAh (18650) The FPV batteries come with a wall charger included. You can use FPV parallel Pigtails to use two of the same capacity batteries with a single accessory. Please note: when using an item with a high draw you will need to use a regulator to avoid damage and cut-offs for the smaller draw items as the high draw items can take all the voltage.Ĭan I use two batteries for a single device? You can use FPV double Pigtails to use multiple items with a single battery. The only drawback of a Lithium-Ion is that it usually has 2~3 times higher purchasing price than AGM, and this means AGM is a more reasonable option for people who just enter the kayaking world and is still in the exploring stage to see whether the sport is for them or not.īatteries sold by Kayaks2Fish are suitable for marine use such as the FPV-POWER 12V 17.5Ah that has an IP67 waterproof hard case and Fusion are rated IP54.Ĭan I use more than one device on a single battery? FYI, a Lowrance Hook2 4x GPS Fishfinder has about 0.5 A draw). Meaning, if it is used one time every single day, it will last about 11~12 years. (For instance, FPV-POWER 17.5 Ah battery that has 4,200 recharge cycles at 1 A discharge up to 90% (DoD). You can use a Lithium-Ion battery 6x longer due to its high recharge cycles.Easy to store a Lithium-Ion battery on a kayak because it comes in half the size and ¼ the weight.Lithium batteries have approx 6x longer life and recharge than AGM batteries.Most lithium batteries come with a smart cut-off which can be drained almost 100% and cut off your accessories before it damages the battery. AGM batteries can only drain down to approx 70% until you damage the cells.AGM battery performance lowers as you drain the battery, where lithium gives you 100% power until depleted.Lithium batteries are much lighter, have more consistent power output and charge much quicker than an AGM battery.What is the difference between an AGM battery and a lithium battery? Generally, you can expect around 17 hours of use when using the FPV-POWER 17.5Ah battery for running larger fishfinders/GPS which do not typically draw more than 1A. It depends on what type of Fishfinder and the features it has. How long will my fish finder last on a battery? To further increase running time use a PWM which can be found here: Please note these running times are approximate and based on an average mid-speed. Here is an outline of how long the motors will last with the recommended batteries: Provided that the motor is run constantly at max speed on a calm day with minimum environmental impact from wind, water current, waves, etc. It depends on a lot of factors such as the environmental conditions, the motor's pound of thrusts, the kayak shape, the kayaks' total load (the sum of the kayaks' weight, the users' weight and the gear's weight), etc.Ī simple scenario: a Kayaks2Fish NG10 kayak with a total load of 130kg, and it is using a Kayaks2Fish Trolling Motor – 32lbs thrust hooked up to an FPV Power 50Ah Battery would last approximately 2 hours. There are lots of things to take into consideration, like water current, weight and wind. ![]() How long will my battery last on the water with a trolling motor? Here is an outline of which battery is suitable for which motor:Ģ0lb motor - We recommend a fusion lithium 12v 20AH battery - ģ0lb/32lb motor - We recommend a FPV 12v 50AH battery - ĥ0lb/55lb motor - We recommend a FPV 12v 50AH battery - Ĩ0lb motor - We recommend a FPV 24v 75AH battery. ![]()
