Overland Power Perfected: Why Antigravity’s Deep Cycle Lithium Battery is a Game Changer

For anyone serious about off-grid travel, power is everything. Between keeping the fridge cold, running communications, and charging all your gear, having a solid battery setup means the difference between a seamless adventure and a frustrating struggle.

After years of overlanding and media production on the road, we’ve tested a range of setups—from AGM deep cycles to different lithium options—but the Antigravity 200aH Deep Cycle Battery has been the single biggest power upgrade we’ve made.

Why Lithium? The Advantage Over Lead-Acid & AGM

If you’re still running lead-acid or AGM batteries, here’s why lithium is worth the upgrade:

✅ Weight Savings – Lithium is significantly lighter, which is crucial when managing payload limits on overland builds. The Antigravity 200aH weighs about half of a traditional AGM battery with the same capacity.

✅ More Usable Power – With lithium, you can discharge nearly 100% of the capacity without damaging the battery. In contrast, lead-acid and AGM batteries degrade if discharged below 50%.

✅ Faster Charging – Lithium batteries recharge much faster than AGM, meaning less engine idling and quicker solar replenishment.

✅ Longevity – Traditional batteries last a few hundred cycles, whereas lithium can last thousands, making it the better long-term investment.

✅ No Battery Anxiety – Unlike AGM, where voltage drops fast, lithium maintains consistent power output. This means stable performance across the entire charge cycle—no dimming lights or struggling accessories.

Why Antigravity? The Features That Set It Apart

Not all lithium batteries are created equal. We’ve run the Antigravity 200aH for the past two years, and it has been a game changer compared to other brands we’ve tested. Here’s why:

🔥 Bluetooth Monitoring – No more guessing your battery status. The built-in Bluetooth app lets us check charge levels in real-time. Whether we’re monitoring power while off-grid or just ensuring a full charge before a trip, it makes life so much easier.

🔋 True Deep Cycle Power – We’ve run lights, an Iceco 60L fridge, WeBoost, Starlink Gen 3, an ARB compressor, and all our media gear (drones, cameras, laptops, etc.) off this battery without any issues. The 200aH capacity gives us the flexibility to stay off-grid longer without stressing about running out of juice.

☀️ Effortless Charging with Solar & Victron Engine Charging – We pair it with Victron DC-DC chargers and a Sunflare 180W solar panel (installed by Adventure Power Solutions), ensuring the battery stays topped off no matter where we are. The fast recharge rate of lithium means even a short drive boosts power quickly.

🛡 Advanced Battery Management System (BMS) – The built-in BMS protects against overcharging, overheating, and excessive discharge. This means safer, more reliable performance, no matter the conditions.

Real-World Performance: 100aH vs. 200aH

Before running the 200aH, we had the 100aH Antigravity Deep Cycle Battery, which worked well for basic overland needs. If we weren’t running Starlink constantly or charging so much media equipment, the 100aH would still be a great option. However, the 200aH gives us extra flexibility to handle heavier power loads without concern.

For those considering an upgrade, here’s a quick guide:

• 100aH Battery → Best for weekend trips, fridge, lights, and occasional power needs.
• 200aH Battery → Ideal for full-time overlanding, Starlink, heavy media production, and extended off-grid stays.

Final Thoughts: Is the Antigravity Battery Worth It?

Absolutely. After two years of running the Antigravity 200aH, we’ve completely eliminated battery anxiety. The ability to charge and go without constantly monitoring voltage levels has been a game-changer.

With smart tech, lightweight design, and rugged reliability, this battery is the perfect power solution for serious overlanders, chase trucks, and off-grid travelers. Whether you’re just upgrading your electrical system or building a fully capable expedition rig, Antigravity’s deep cycle lithium batteries deliver unmatched performance.

If you’re still running AGM or lead-acid, it’s time to make the switch. You won’t regret it.
