High-Output Alternator Upgrades for Lithium Banks
Charge Faster.
Stay Longer.
Lithium batteries crave power. Stock alternators can't keep up. We install high-output systems that turn your engine into a rapid-charging powerhouse.
Stop the Burnout
Lithium batteries have very low resistance, forcing stock alternators to run at 100% output until they overheat and fail. Our upgrades are built to run hard.
Smart Regulation
We install external regulators (Balmar MC-618 or Wakespeed WS500) that monitor alternator temperature and adjust output to charge Lithium safely and efficiently.
Serpentine Conversion
Old V-belts slip under high electrical loads. We install serpentine pulley kits (AltMount) to transfer maximum horsepower to your alternator without belt dust.
The Power Upgrade.
A technical installation for serious off-grid energy.
Audit
We analyze your engine brackets and battery bank size to select the right amperage alternator (100A - 250A).
Mount
We replace standard pulleys with wide serpentine kits and mount the new heavy-duty alternator securely to the engine block.
Wire
We install heavy-gauge positive/negative cabling and connect the external regulator harness with temp sensors.
Program
We connect a laptop to program the regulator with the specific charging profile required by your Lithium battery manufacturer.
Industrial Grade.
Equipment designed for continuous high output.
Top Tier Brands.
We partner with the leaders in marine charging technology.
Common Questions
Why can't I use my stock alternator?
Stock alternators are designed to top off starter batteries, not bulk charge large lithium banks. They lack temperature protection and will burn themselves out.
Do I really need a serpentine belt?
If you go above 100 amps, yes. A single V-belt will slip, squeal, and wear out rapidly under the load of a high-output alternator.
