Since 1950 the shortest ferry route in Xiamen has provided a lifeline to Gulangyu. It’s a highly-scenic ride which today takes only two minutes over the narrow but deceptively 17-meter-deep sound. The current Gulangyu has transported passengers at 150-minute intervals 48000 times annually since 2010. For ten years it used diesel for electric power generation and propulsion, consuming 100,000 liters of fuel each year. In the drive to cut costs and achieve more sustainable the operation, the ferry sought solutions to reduce the fuel consumption for the auxiliary power generators. The process was a collaborative development project with Gulangyu, Wisdom Power, The shipyard, and contractor, where the ferry was assessed, the battery supply and power conversion extensively tested, and finally the ferry equipped with a customized hybrid power generation system. From 19 hours of diesel power…. Before the retrofit, the two diesel auxiliary generators were powering the hotel load, bridge ...

The golf cart battery industry is in a state of flux. On one hand we have golf cart manufacturers and retailers that realize lithium-ion batteries are better for electric golf cart performance and longevity than lead acid batteries. On the other hand are consumers who resist the high upfront cost of Lithium ion Golf Cart Batteries, and consequently still rely on inferior lead-acid battery options. With operational costs being a major concern for anyone with a golf car fleet, it’s important to point out that there is the initial cost of a lithium iron phosphate pack (LiFePO4), plus the required additional equipment necessary to operate it. A single LiFePO4 cell has a nominal voltage of 3.2 volts, thus requiring 15 cells in series for a 48-volt deep cycle battery pack. The average retail price of one 100 Ah (amp-hour) cell is $155, putting the pack cost at $2325. A compatible BMS and charger cost $290 and $1075 respectively. Altogether, a conversion would cost $3690 and will provi...

Lead-acid RV batteries may still dominate the market, but many RV adventurers are moving to lithium batteries instead because they’re a superior alternative to traditional batteries. The benefits of choosing LiFePO4 over lead-acid for any application are numerous. And, when it comes to your RV, there are specific advantages that make LiFePO4 RV batteries the ideal choice. 1 – SUBSTANTIALLY CONSTANT VOLTAGE The voltage of all conventional deep-cycle batteries (as well as AGMs) constantly falls as they discharge. This is typically from 12.75–11.4 volts. The voltage also falls as load increases. Any LiFePO4 suitable for (and in) RV use, however, will provide the peak power required. It will also maintain substantially constant voltage regardless of the load. In practice that voltage is likely to be from 13.1–12.9 volts. Readers with a physics background will realize this provides a correspondingly higher output of about 10% (in terms of watt hours). 2. They’re safe. Your RV i...

Here at Wisdom Power BSLBATT Lithium we pride ourselves on the domestic manufacturing of robust and reliable LiFePO4 batteries. It probably comes as no surprise that we get a lot of battery-related questions. One of the most common queries is “I need more power! Do you have a battery that can give me more volts or more amps?” The answer is yes. All of our batteries can be connected to produce more power to run bigger motors (voltage – v), or extra capacity (amp hours – Ah). This called wiring a battery in series or in lithium Batteries Parallel. Wiring a battery in series is a way to increase the voltage of a battery. For example if you connect two of our 12 Volt, 10 Ah batteries in series you will create one battery that has 24 Volts and 10 Amp-hours. Since many electric motors in kayaks, bicycles, and scooters run on 24 volts this is a common way of wiring batteries. Lithium ion batteries in parallelis to increase the amp hours of a battery (i.e. how long the battery will run o...

Lithium-based batteries are taking the lead in nickel-cadmium batteries, thanks to their stability and relatively low maintenance nature. Plus, the self-discharge rate is lower than half the rate of a nickel battery, and there is little to no harm when the cells are exposed. Although the lithium-based battery has many advantages, it still has its limits and drawbacks. That’s why it’s so important to understand exactly how to care for and prolong the life of your lithium-based battery. Hot Temperatures As with most batteries, lithium-based batteries need to be kept at cooler temperatures. The higher the temperature the greater the self-discharge rate. Pro Tip: Try storing your battery at temperatures around 68 °F. Because charging and using the battery creates heat you should give your battery time to cool down in-between times of charging and use. This is one of the most effective ways of prolonging the life of any battery. Cold Temperatures Just as heat can shorten your battery...

      We get a lot of questions about how to properly store batteries. Let’s break down the real do’s and don’ts for storing your batteries in the offseason. Some old batteries may not accept a charge and will heat up on charging. CAUTION: If at any time the battery gets hot (above 125 degrees F) or acid comes out of vent caps, STOP charging. Have your battery checked？ Charging may not be possible？ It may have to be replaced. CAUTION: If you feel your battery is not charged after these times, have it checked. Charging for longer times may damage your battery. Stop charging and have the battery checked. Do: Get It Clean and Keep It Clean Dirt and corrosion can increase a battery’s discharge rate. It’s important to clean the battery casing and the terminals thoroughly before you connect anything to it and throughout the battery’s life cycle. As long as you properly cleaned the battery before you store it, you should be able to just keep it clean and dust-free with a clean dry ra...
