What riders say about the 5000mAh 12V Battery
Answers
Frequently asked questions
Can I use the 5000mAh battery to power more than one garment at a time?
We do not recommend using the 5000mAh battery to power multiple garments simultaneously. While it technically supports 12V output, it has a 6A maximum current limit, which means powering more than one garment, such as a jacket and gloves together, can quickly exceed this limit. Doing so can lead to significantly reduced run times, performance drops, or even damage to the battery. For multi garment setups, a direct bike connection is the safer and more efficient option.
How long does it take to fully charge the 5000mAh battery?
When using the KEIS 30W Fast Charger, sold separately, the battery can fully charge in approximately 3 to 4 hours, depending on the remaining charge and ambient temperature. Using a lower wattage charger or non fast charging USB source will increase charging time significantly. The USB-C port enables fast input, and the included cable ensures you have the right connection straight out of the box.
How do I know how much battery life is left?
The LCD capacity display shows a real time percentage readout of the battery’s remaining charge. This is far more accurate than traditional LED indicators and allows you to better plan when to recharge, especially helpful on longer rides or trips where access to power may be limited.
Which KEIS garments is the 5000mAh battery compatible with?
The battery is compatible with all 12V KEIS heated jackets, bodywarmers, vests, gloves, and trousers, including the latest ULTRAFLEX and EXTREME ranges. However, run time varies significantly depending on the garment’s power draw. For example, bodywarmers may run for up to 10 hours on low, while high power jackets like the J505 EXTREME may run for only around 1 hour on medium power.
What does the E2 error code mean and how can I fix it?
This error code is present when the battery is being overcharged with a current higher than 6A, which is the max deliverable power of the battery. In order to solve this battery error code, simply reset the battery by holding down the power button. Ensure your charger is not short circuited, as this could cause a spike in power delivery, and if the issue persists contact our customer service team.
