Lithium LiFePO₄ Batteries – Built for Real Work, Built to Last
If you've used lead-acid batteries before, you know how it goes. A couple of years, maybe less, and they start struggling. Slow charging, less runtime, and eventually they just give up.
That's exactly why we built our LiFePO₄ lithium batteries the way we did.
Made for golf carts, boats, RVs, solar storage, floor machines, and electric vehicles – basically anything that needs reliable power day after day.
What makes them different
6000+ cycles. That's 5 to 8 years of daily use. Compared to lead-acid, which usually quits after 500 cycles (2-3 years), these actually last.
Fast charging. From empty to full in about 2 hours with 150A max charge current. No more plugging in overnight and hoping it's ready by morning.
Wide temperature range. -20°C to 60°C working temp. Cold mornings or hot afternoons, they keep running.
Built-in BMS. Protects against overcharge, over-discharge, overheat, overcurrent, short circuit, and voltage spikes. Also keeps cells balanced – either passive or active balance depending on your needs.
IP65 waterproof. Rain, splashes, damp engine compartments – no problem. The ABS case is tough, and the copper terminals handle high current without heating up.
Carry-friendly. There's a built-in strap, so moving them around isn't a workout.
Voltages and capacities
We cover the common ones:
-
12.8V (12V systems) – up to 4 in series
-
24V – up to 2 in series
-
36V
-
48V
Capacities from 50Ah to 280Ah. If you need something in between, we can do that too. Custom Bluetooth monitoring and display options are available.
Where people use them
-
Golf carts that need to run all day without voltage drop
-
Trolling motors on boats where weight and space matter
-
RVs and campers that want silent, fume-free power
-
Off-grid solar setups that cycle daily
-
Floor scrubbers and sweepers in commercial buildings
-
Small EVs and utility vehicles
If your equipment runs on batteries, there's a good chance these will work for you.
