Deep Cycle Battery for Custom Setups for Custom Setups

Pack heavy power into a lighter frame. You get 4019Wh of clean lithium energy built for daily reliability.

Key Features

  • Massive Energy Storage Stores 4019Wh of usable power at full charge.
  • 15,000+ Deep Cycles Lasts thirty times longer than standard lead-acid designs.
  • 200A Built-in BMS Shields against overcharge, shorts, and rapid current spikes.
  • Compact Body Design Scales down physical bulk while doubling capacity.

Product Description

You deserve reliable off-grid juice for your gear. This lithium iron phosphate cell delivers steady voltage without heavy acid plates. The integrated management system watches temperature and current so you never guess about safety. Expand four units side by side to reach sixty-plus kilowatt hours when your projects demand peak output.

Product Overview

This is a modern twelve-point-eight volt lithium deep cycle battery built for continuous load discharge. You can swap it directly into setups that previously used bulky flooded cells. The polymer shell protects internal components while keeping transport weight manageable.

Key Benefits

  • Zero Maintenance Routine Runs sealed and self-regulating from day one.
  • Extreme Climate Readiness Auto-cuts charging when ambient heat hits 158°F.
  • Rapid Expansion Capability Connect multiple packs in series or parallel setups.
  • Consistent Device Performance Maintains flat voltage curves until depletion.

Features

  • M8 Terminal Posts Secure direct wiring without adapter frustration.
  • Low-Temperature Cut-Off Stops freeze risk during winter charging sessions.
  • Wired Control Design Omits Bluetooth to preserve internal routing space.

Specifications

  • Nominal Voltage 12.8V sustained output profile.
  • Charge Threshold Accepts 14.4V±0.2V input safely.
  • Chemistry Type Lithium Iron Phosphate construction.
  • Physical Size 15.04×7.6×9.82 inches overall.
  • Unit Weight 61.73 pounds fully assembled.

What’s Included

One complete twelve volt lithium battery module arrives ready to mount. Plastic terminal caps shield contact points during transit. Technical documentation sits securely inside the shipment carton.

How to Use

Connect positive cables to the left post and negatives to the right. Program your charge controller to match lithium absorption steps. Enable load bypass so your appliances draw directly from the module. Link extra packs only when the main system turns off.

Customer Benefits

You save shelf space by removing water top-ups and equalization routines. Your equipment runs quieter because voltage sag stays minimal under heavy draws. Emergency lighting stays bright through multi-day outage windows. Solar arrays capture peak daylight without backing off early.

Ideal Uses

Tackle weekend camping trips with silent freezer operation. Power rooftop digital cameras across remote job sites. Run household routers and modems during grid flickers. Lift boat depth finders and anchor lights straight above the waterline.

Who It’s For

Traveling van owners chasing extended road freedom. Offshore anglers demanding dependable fish finder juice. DIY homestead builders scaling micro-grid networks. Backup technicians protecting sensitive server racks.

5 Frequently Asked Questions

  • Can I stack these modules for higher voltage? Yes, configure up to four parallel banks or series strings to exceed fifty-one volts safely.
  • Do I need a special charger for this chemistry? Only select a DC-DC converter matched to lithium absorption profiles.
  • What happens if I drain it past ten volts? The built-in system isolates the load automatically to prevent cell damage.
  • Is outdoor mounting safe year-round? The weather-shielded case handles rain exposure without corrosion risks.
  • Does the brand name appear on the casing? Labels mark specifications for warranty tracking and service lookup.
