1. Can I use a stock controller with a 72V or 81V battery?
No, it’ll fry. You’ll need an upgraded controller like a BAC TORP or new Moxin.
2. Which Controllers do work with your 72v or 81v batteries?
Our batteries pair perfectly with BAC, Torp, and Moxin controllers. We don’t recommend KO due to reliability and safety issues
3. Do you build your own custom batteries or import them made by someone else?
No Chinese imports here. Every battery we sell is hand-built in Germany using top-tier cells. Built for performance, not compromise.
4. What cells do you use in your batteries?
You get a choice - Samsung 50S (35A) or Molicel P50B (50A). Both are top-tier 21700 cells known for high performance and reliability.
5. Do you ship your batteries to Europe and its regions?
Yes - we ship across the UK, EU, and even further. Proper packaging, no drama
6. Do you rebuild or rework other brands' batteries?
No, sorry - we only work on what we’ve built. Safety comes first.
7. Do your batteries come with a warranty?
Yes - all EV Freaks batteries include 12 months full warranty and full support after that too
8. Can I use my stock charger with your battery?
Nope. You’ll get a charger with the battery - matched for safety and speed
9. How long does a Sur Ron battery last?
With proper care, up to around 1,000 full charge cycles - that’s years of riding without worries. Take a look at our battery maintenance advices to keep it in top shape
10.Can I collect the battery in person or drop my bike for installation?
Yes - you can collect or bring your bike and we’ll do a full install and test (adress added ig)
11. How much range will I get?
Depends on how you ride, but typically you can expect 70–? km per charge. Casual cruisers get more. Bigger battery capacity = longer rides
12.How fast with your 72V battery kit and BAC8000 controller?
Up to (idk 70 ig) mph+ if you pair it right. 81V builds push even harder.
