If you’ve already made the leap to an LTO SCiB car audio battery bank, first off — smart move. Honestly, there’s nothing else in the car audio world that can handle brutal SPL power demands while staying safe and consistent. But here’s the part most people don’t realize: just installing your lithium bank isn’t the same as getting its full performance.
I’ve seen it time and time again here in NZ — someone builds a monster system with a 20K amp, runs a bank of lithium titanate cells, and still struggles with voltage drops because of little setup details. And it’s frustrating. You know your batteries are capable of so much more… they just need to be dialed in properly.
So, let’s break it down. Here are the top three things you can do to get maximum performance from your LTO SCiB battery bank in a high-output car audio system.
1. Dial in your charge voltage (the sweet spot matters)
Your charging system is the foundation of everything. SCiB LTO cells perform best when kept in the sweet spot of 15.6V – 15.9V. Too low and you’re not giving your amp the current it craves. Too high and you’re only stressing your system without real gains.
When I first ran my setup at 14.6V, bass hits felt flat. After tuning my high-output alternator to charge at 15.8V, the difference was night and day. The bass stayed stronger for longer, and the whole system just felt more effortless.

LTO SCiB car audio banks built to handle aggressive charging. Pair one with a quality alternator upgrade and you’ll notice the difference instantly.
2. Keep your wiring and connections flawless
This one gets overlooked way too often. LTO batteries can dump thousands of amps on demand, and that means every tiny bit of resistance in your wiring is holding you back. Loose lugs. Undersized runs. Weak grounds. All of them add up to lost performance.
I’ve worked on builds where someone had a beautiful 36Ah SCiB bank, but their ground lug was half loose. Result? Voltage drop city. Once it was fixed, the system suddenly felt like it had woken up from a nap.
So here’s the rule: use proper copper lugs, torque them correctly, and re-check them often. Big SPL current doesn’t forgive sloppy installs.

3. Fuse smart (ANL and CNL are your best friends)
A lot of people think fusing is about limiting performance. Not true. With lithium titanate banks, fuses are about letting your system breathe safely.
Run too small of a fuse and you’ll blow them every time you crank it. Run no fuses, or ones way too big, and you’re asking for melted wiring or worse. The key is matching the fuse rating to your wiring and amplifier demand.
In my setups, I fuse each section of the LTO bank individually, plus the main run. That way, if something goes wrong with one part of the system, it doesn’t take down the whole build. It’s peace of mind when you’re running a 20,000W RMS monster system at full tilt.

Final Thoughts
At the end of the day, an LTO SCiB battery bank is like putting a race engine in your car audio setup. It’ll give you insane performance, but only if you feed it right and respect the details.
- ✅ Nail your charging voltage.
- ✅ Keep wiring and grounds perfect.
- ✅ Fuse with purpose, not guesswork.
Do those three things and you’ll unlock the full potential of your SCiB bank. More stable voltage. Cleaner, harder-hitting bass. And the confidence that your build will run strong every time you crank it up.
Because let’s be honest… there’s nothing better than flexing at an NZ car audio meet, knowing your system is built right and your lithium titanate batteries aren’t even breaking a sweat.
FAQs About LTO SCiB Car Audio Batteries
Are SCiB LTO batteries better than AGM for car audio?
Absolutely. AGM batteries were the standard for years, but they simply can’t deliver the same power density or cycle life. SCiB lithium titanate cells charge faster, handle extreme current draw, and last thousands more cycles. For high-performance car audio in NZ and AU, LTO is the clear winner.
How long do SCiB LTO car audio batteries last?
With proper charging (15.6V–15.9V) and good maintenance, SCiB cells can last 15–20 years in a car audio setup. Compare that to an AGM, which often needs replacing every 3–4 years, and the value becomes obvious.
Can I run an LTO SCiB bank with my stock alternator?
Technically, yes, but you won’t be getting the best performance. A stock alternator usually charges too low for SCiB cells. For big SPL builds or anything over 5,000W RMS, you’ll want a high-output alternator matched to 15.8V charging to unlock the real power of your lithium bank.
Do I need to fuse my LTO bank?
Yes — always. LTO batteries can deliver insane amounts of current instantly. Proper ANL or CNL fusing protects your wiring, amps, and batteries while still letting your system play at full tilt.
