The recent mobility scooter fire outside a Te Kūiti supermarket was an unsettling reminder of how serious a vehicle fire can be. According to 1News, flames spread from the scooter to the supermarket entrance, prompting an evacuation.
The report does not identify the battery type or establish what caused the fire. For anyone who relies on a mobility scooter, though, a story like this can understandably raise questions about their own vehicle: is the battery safe, and am I charging it correctly?
Those questions matter across electric vehicles, from mobility scooters and off-road vehicles to golf and utility buggies. Battery safety depends on the whole system, including the cells, protective electronics, charger and ongoing care.
At EV East, battery safety is part of how we choose our vehicles and support the people using them. We look at the complete system: the type and quality of the battery, the protections built around it, the charger supplied with it, and the advice available when you need a hand.
Different vehicles have different needs. That is why our range uses more than one battery technology, from AGM batteries in our mobility scooters to NMC lithium batteries in the Veehop and LFP lithium batteries in our EKO buggies.
What comes with the purchase matters
An attractive online price can be tempting. When buying directly from an overseas marketplace such as Alibaba, it is worth asking what you can verify about the battery cells, battery management system and charger—and who will help locally if something goes wrong. The level of product information and after-sales support can vary considerably between suppliers.
Ask which battery chemistry is used, what protections the battery management system provides, whether the charger is matched to the pack, and who can assess a fault or supply replacement parts. If those answers are hard to obtain, it is harder to judge what you are buying.
Our approach at EV East is to choose suitable battery systems, supply the matched charger and provide local advice and ongoing support. The battery technology varies across our range because different vehicles have different needs.
AGM batteries in our mobility scooters
AGM stands for absorbent glass mat. These are sealed lead-acid batteries, rather than lithium batteries, and are a well-established option for mobility scooters. They offer dependable everyday power without the need to top up the battery with water.
The automatic charger we supply with our AGM mobility scooters is designed to be left connected and switched on. It senses when the batteries are fully charged, stops charging, and checks periodically to top them up when needed. Leaving it connected overnight, or between uses, is part of its intended operation and helps keep the batteries in good condition.
There is no need to second-guess the charger by switching it off because you think the batteries must be full. Let it manage the charging cycle. AGM batteries last best when kept charged; leaving them partly discharged for long periods can reduce their capacity and shorten their life.
For these AGM systems, leaving the supplied automatic charger connected is normal intended use. Follow the usual precautions for electrical equipment in the home: keep the charger dry and uncovered, allow airflow, keep it clear of flammable materials, and make sure cables, plugs and connections are in good condition. This advice applies to the AGM systems and chargers we supply; other battery types or chargers may need a different routine. If you are unsure, get in touch and we can help.
NMC lithium batteries in the Veehop
NMC is short for nickel manganese cobalt. This lithium battery chemistry can store a substantial amount of energy in a relatively compact, light package, which suits a vehicle such as the Veehop.
The chemistry is only part of the story. Quality cells, sound pack construction and a suitable battery management system all matter. We prioritise the quality of the complete battery system when choosing the lithium vehicles we supply.
A battery management system, often called a BMS, is the electronics that helps keep a lithium battery operating within its limits. Depending on its design, it can monitor cell voltages, temperature and current, and interrupt charging or use when an unsafe condition is detected. These protections reduce risk, but cannot prevent every possible failure or undo physical damage.
LFP lithium batteries in our EKO buggies
LFP stands for lithium iron phosphate, also written LiFePO4. It generally has lower energy density than NMC, meaning more battery weight or space is needed to store the same amount of energy. In return, it offers greater thermal stability, making it an attractive choice for our buggies.
That stability is a useful safety advantage. LFP still needs a well-built battery pack, appropriate battery management, the correct charger and sensible care. Choosing the chemistry is one part of choosing a reliable system.
We supply the matched charger
Our vehicles come with a charger matched to their battery system. You should not need to guess which charger to buy or whether a charger from another vehicle will do the job.
A plug that fits does not prove a charger is compatible. Battery chemistry, voltage and charging requirements must match. If your charger needs replacing, contact us before using an alternative. The same applies if you are considering a different battery or a change from lead-acid to lithium: it needs to be assessed as a complete system.
A few habits that help keep charging safe
Use the supplied or approved charger and follow your vehicle’s charging instructions.
Charge in a dry area with airflow. Keep the charger uncovered and clear of flammable materials.
Keep doorways and escape routes clear, and check cables and plugs for damage.
For lithium batteries, Fire and Emergency New Zealand recommends charging while you are awake and nearby, then unplugging once charging is complete.
Stop using or charging a battery if you notice swelling, leaking, unusual heat or damage. Seek advice before using it again.
If a battery emits smoke or flames, move away, get others to safety and call 111. Do not try to carry a smoking or burning battery outside.
Advice is part of the support
A battery system should come with someone you can ask. Whether you use a mobility scooter, an off-road vehicle or a buggy, we are happy to help you understand its battery and charging routine.
If you are unsure about charging, battery condition, storage or a replacement, get in touch with EV East. Tell us which vehicle you have and what you have noticed, and we can help you work out the next step.
Our aim is straightforward: suitable battery systems, matched chargers and practical support so you can use your electric vehicle with confidence.
