The Hidden Danger Behind Cheap PMD Batteries:
What Every Rider Should Know 

Personal mobility devices (PMDs), e-scooters, and power-assisted bicycles (PABs) have become increasingly popular in Singapore. They offer convenience, fun, and a great way to get around the city. However, there is a growing and serious safety concern many riders may not realize — unsafe, uncertified batteries flooding the market.

Why Are Some PMDs Catching Fire?

You may have heard stories of tragic fires caused by modified e-scooters or PMDs, sometimes leading to entire homes being damaged or destroyed. On the other hand, many modified devices run safely without issue. The key difference lies in the quality of the batteries used and, importantly, the knowledge and choices of the user.

The Real Problem: Budget and Awareness

Most fires involve riders who are either unaware or constrained by budget. Often, these riders:

• DIY their modifications, sourcing parts and batteries on their own

• Choose cheaper batteries that look good on paper but are low quality

• Purchase from unverified sellers or online marketplaces without proper certification

For example, there are sellers on platforms like Carousell advertising batteries claiming to be branded Panasonic or LG cells at low prices ranging from $360 to $460. But in reality, many of these batteries:

• Contain low-grade cells from unknown sources (sometimes India or China)

• Lack proper Battery Management Systems (BMS) that prevent overheating or short circuits

• Are actually designed for energy storage applications, not for mobility devices

• Have poor build quality and unsafe welding

The Consequences Are Serious

Unsafe batteries can overheat, catch fire, or explode — putting riders, pedestrians, and property at risk. This risk is not hypothetical; we have seen multiple cases where riders returned with faulty batteries purchased from these sellers for repair. Many of these batteries are ticking time bombs waiting to ignite.

What Can You Do?

1. Avoid cheap, unverified batteries. If a battery sounds too good to be true, it probably is.

2. Never buy secondhand batteries from unknown sellers. Many resell unsafe batteries to get rid of faulty stock.

3. Buy only from certified and compliant workshops and sellers. Trusted shops test and use high-quality components with proper safety features.

4. Educate yourself on battery safety. Know the signs of poor quality and ask questions before purchasing.
