Enerdrive B-Tec Ultra 12V 100Ah FAQs

1. What does the IP67 rating mean in practice?
The battery is fully protected against dust and can handle being submerged in up to a metre of water for short periods. That matters for underfloor mounts, boat installs and anywhere it might cop water rather than just dust.

2. Will it charge in cold weather?
Yes, a cell heater is built in specifically to allow charging in cold conditions, which is where most lithium batteries stop accepting a charge. Worth knowing if you head into the high country or south in winter.

3. What can it run?
Around 150A continuous at 25°C, with roughly 500A available in a short burst for start-up surges. Maximum charge current is about 100A, and nominal charge voltage is 14.2 to 14.6V.

4. How do I check how much charge is left?
Two ways. LED indicators on the battery itself show state of charge in 25% increments and flag faults, and the Enerdrive B-TEC app gives real-time status wirelessly. There's also an on/off switch to isolate the terminals for storage, and the battery can be linked in parallel or series with others.
