Scooterland Mobility provides a unique option, compared to other mobility scooter companies. Partnering with Leander International, with their new designed, lighter, and longer Lithium Iron(Li-Ion) Batteries, Scooterland Mobility can upgrade any mobility scooter and all portable electric wheelchairs with Lithium batteries.
Due to Lithium being the lightest metal and being a member of the alkali group of elements, it can contain a huge amount of energy with its high energy density rate. Therefore, being highly reactive stores a high quantity of power. When contained, a lithium battery energy storage capacity can store u to 150 watt-hours per kilogram of battery. Lithium-ion can store up to 6 times more than its common and cheaper counterpart, Lead Acid Battery. This is a tremendous advantage for mobility scooters.
Lithium batteries are being more commonly used in a lot of electric appliances, to their innate quality of being light and longer-lasting energy consumption. From laptops to smartphones, Lithium batteries have created a foundation of energy-efficient supply.
Thus, why not Electric Wheelchairs and Mobility Scooters? If there is a will there is a way. Leander International offers their new customized Lithium Batteries, aptly named Lithium Iron(Li-Ion) and Lithium Iron Phosphate (LiFEPO4) batteries. These batteries are constructed utilizing individual cells in a series, parallax one another. These lithium cells are controlled by a Battery Management System. The BMS allows the battery to perform safely without fear of a thermal runaway.
They are lighter weight and have a self-discharge rate of 5% to 10%, only annually compared to nickel which has a discharge rate of 30% a year. Lithium Batteries can be recharged, even if it’s not yet fully drained, unlike other commonly used batteries which will develop what is commonly known as the “memory effect” in batteries. These effects can hamper the lifespan of a battery, but unlike lead-acid batteries, lithium batteries negate this effect, thus increasing its longevity by 5 years more. This longer total lifespan is one of the primary reasons for it being a great choice to upgrade to Lithium Batteries.
Typically, Lithium batteries will perform well for 7 years compared to as little as 2 years for the lead-acid gel and gel-mat equivalents. They are up to two-thirds lighter in weight than standard AGM batteries. Safe battery operation is achieved as the built-in BMS prevents short circuits, over-voltage, and over-discharge, as well as thermal runaway. The batteries are Maintenance Free. The Lithium batteries are charged by an intelligent charger, 29.4 volts for Li-Ion and 29.2 volts for LiFePO4. These chargers switch off when the battery reaches full capacity, as, unlike their lead-acid equivalents, they have a very low internal discharge and do not like to be left on a trickle charge. The nominal voltage of our Li-Ion batteries is 25.9 volts and the LiFePO4 is 25.6 volts. However, they are ideal replacements for many applications using 12-volt batteries in series in a 24-volt system. Batteries in the Leander International range incorporate Bluetooth monitoring, so it is possible to monitor the state of charge of the battery using an App on a mobile phone.

FAQS
How are Lithium batteries constructed?
Unlike VRLA (Valve Regulated Lead Acid) batteries or traditional flooded wet cell batteries, Lithium batteries are classified as “dry” batteries as they do not generate power from a liquid solution and they do not produce gas. Instead, power is generated by the movement of lithium ions between the negative and positive electrodes. The positive electrode is made from a chemical compound called Lithium Iron (Li-Ion) or Lithium Iron Phosphate (LiFEPO4). The negative electrode is generally made from carbon (graphite).
What is a Battery Management System (BMS)?
A critical component of any high-quality Lithium battery is the Battery Management System (BMS). The BMS is a sophisticated instrument that sits inside the battery and ensures each battery cell is charged and discharged equally. When a single Lithium cell is fully charged, the voltage rises suddenly and can reach dangerous levels very quickly. If this happens in only one cell, that cell can reach dangerous voltages before the total pack voltage is high enough to register as fully charged. To prevent this from occurring, the BMS balances the cells to ensure they all charge and discharge equally as well as preventing them from over-discharging.
What are the benefits of using Lithium batteries?
A high-quality Lithium battery with a sophisticated BMS will automatically disconnect loads if the voltage goes too low, and disconnect chargers if the voltage goes too high. Lithium batteries have a greater cycle life than VRLA batteries and greater useable power. Lithium technology can efficiently provide power in high energy demanding applications and will maintain their voltage throughout almost the entire discharge curve. Additionally, Lithium Phosphate batteries are on average three times lighter in weight than VRLA batteries and have been proven to cope with ambient temperatures of up to 60°C. Along with this, Lithium Phosphate batteries have a greater energy density, meaning you can get a larger capacity battery into the same dimensions of a VRLA battery. Finally, Lithium batteries can be designed and manufactured to any footprint. They can be reshaped to fit into any existing cavity or around specific fittings. The battery cells can be packed to be long or short and fat.
