ONYX AMORGE Batteries

This page provides a detailed reference for AMORGE battery options for ONYX platforms, including pack construction, supported 21700 cells, tabless cell options, voltage configurations, capacity, discharge limits, connector setups, fitment, and pricing.

It also covers battery architecture (series and parallel configurations), compares 72V, 84V, and 96V systems, and explains how cell selection, tabless battery technology, and lithium battery chemistry affect power output, range, thermal behavior, and overall performance.

AMORGE battery options covered here include:

• ONYX RCR (72V / 84V / 96V)
• ONYX CTY2 (60V)

Battery Buying Recommendations

Battery choice depends on whether you want a direct replacement, a CTY2 battery, or a higher-output 72V platform setup. AMORGE is better suited to testing and performance use than to stock replacement comparisons, peace of mind, or bargain hunting.

For the rider who wants a straightforward 72V RCR stick replacement, buying the battery from ONYX Motors is the smart choice.

ONYX Motors is naturally going to support the battery they sell. That does not always align with what seems sensible from an individual buyer’s perspective, but from the company side it makes little sense to spend time supporting a third-party battery they did not build or sell.

Because battery technology and pricing move around often, it is always smart to ask questions and be specific about how you plan to use the battery.

Current Cell Selection Rules

Right now, these three rules hold true, but they could change multiple times over the course of this year.

When AMORGE Makes Sense

AMORGE is the right direction when the goal is more than just replacing a stock battery.

If the real goal is a faster JAWS MODE setup, it usually makes more sense to plan for the final battery target from the start.

AMORGE Battery Construction

Battery Cell Selection

Your battery determines the power ceiling, voltage stability, and thermal behavior of your ONYX.

Higher performance builds require batteries with lower internal resistance and higher discharge capability.

High output modes such as SICKO MODE place significantly greater load on the battery pack and should only be used with high-discharge cells.

Battery Architecture (Series Configuration)

Electric vehicle batteries use series (S) and parallel (P) cell groups.

• Series (S) increases voltage
• Parallel (P) increases capacity and current capability

Higher series count increases battery voltage, which raises the motor speed where back-EMF begins to limit current.

This allows the motor to maintain torque at higher RPM, resulting in:

• higher top speed
• stronger acceleration at higher speeds
• improved effectiveness of field weakening

Higher voltage systems also increase electrical stress on system components and may require:

• controllers rated for higher voltage
• upgraded wiring and connectors
• careful thermal management

Voltage Comparison (72V vs 84V vs 96V)

Battery voltage determines the speed ceiling and high-RPM performance of the 72V ONYX platform.

Tabless Lithium Cells in ONYX Packs

ONYX battery packs are typically built using 21700-format lithium-ion cells. While chemistry determines energy density and lifespan, cell architecture determines how efficiently the battery can deliver current.

One of the most significant improvements in modern lithium cells is tabless cell design, which reduces internal resistance and dramatically improves high-current performance.

Traditional cylindrical lithium-ion cells connect the internal electrode layers to the battery terminals using small current-collector tabs. These tabs act as electrical bottlenecks and concentrate heat during heavy discharge.

A tabless architecture removes this bottleneck by allowing current to flow evenly across the entire electrode edge. This spreads current across a much larger surface area and significantly improves electrical and thermal performance.

The concept became widely known through Tesla’s 4680 tabless battery cell, but several manufacturers now produce tabless 21700 cells that fit directly into ONYX battery packs.

High-Performance 21700 Cells for ONYX Builds

Not all cells with the same advertised current rating perform the same under load. Differences in internal resistance, electrode design, and thermal behavior can produce very different real-world results.

Two cells may both advertise 30A continuous discharge, but one may maintain voltage stability and thermal performance far better during sustained acceleration.

Cells such as Tenpower 50XG, Reliance RS50, BAK 50D, BAK 45D, and EVE 50PL represent the newest generation of tabless high-discharge 21700 cells.

These cells are particularly well suited for high-performance ONYX builds, where high-current controllers and aggressive acceleration demand strong voltage stability.

ONYX Tabless Lithium Battery Upgrade

Because the ONYX RCR battery pack uses 21700 cells, tabless models such as Tenpower 50XG (5000mAh) and EVE 50PL (5000mAh) integrate easily into existing pack layouts.

These cells allow builders to push ONYX battery packs into very high-current configurations while maintaining improved thermal stability.

Typical applications include:

• high-current motor controllers
• field weakening setups
• racing configurations
• aggressive launch tuning

Benefits of Tabless Cell Architecture

Tabless cells provide several measurable improvements over traditional tabbed cylindrical cells.

• Lower internal resistance
• Reduced voltage sag during acceleration
• Higher sustained discharge capability
• Improved heat distribution across the cell
• Better durability under repeated high-current loads

In practical ONYX builds this translates to:

• smoother acceleration
• more consistent power delivery at low state-of-charge
• cooler battery temperatures during sustained riding

Battery Chemistries Used in ONYX Packs

In addition to cell architecture, battery chemistry plays a major role in how a pack performs.

Different chemistries affect:

• range (energy density)
• power delivery
• cycle life
• safety characteristics
• temperature tolerance
• pack weight
• cost

While several chemistries exist, most high-performance ONYX packs use NMC-based lithium-ion cells.

Quick Chemistry Selection Guide

Lithium Battery Chemistry Comparison

Lithium Nickel Manganese Cobalt Oxide (NMC)

Most performance-oriented ONYX battery packs use NMC chemistry.

NMC offers a balanced combination of:

• high energy density
• strong power output
• reasonable cycle life
• compact pack size

Most modern 21700 performance cells from manufacturers such as Molicel, Samsung, EVE, and BAK use variations of NMC chemistry.

Lithium Nickel Cobalt Aluminum Oxide (NCA)

NCA chemistry pushes energy density slightly higher than NMC.

Because of its thermal sensitivity, NCA typically requires careful BMS configuration and proper pack cooling.

Lithium Iron Phosphate (LFP)

LFP chemistry prioritizes stability and lifespan.

Trade-offs include larger and heavier battery packs for the same capacity.

Lithium Titanate (LTO)

LTO batteries are designed for extreme longevity and fast charging.

Because of the lower energy density and high cost, LTO is rarely used in lightweight EV platforms like ONYX.

Lithium Manganese Oxide (LMO)

LMO chemistry provides strong power output but shorter lifespan.

LMO is frequently blended with NMC to balance cost and power performance.

Emerging Battery Chemistries

Several next-generation chemistries are currently being researched to improve lithium battery performance.

These technologies aim to increase:

• energy density
• safety
• cycle life
• manufacturing efficiency

However, most remain early-stage or limited to experimental deployments.

Solid-State and Semi-Solid-State Batteries

The term solid-state battery is often used broadly and can refer to several different approaches.

Solid-State Lithium Metal

Lithium-metal batteries replace the traditional graphite anode with pure lithium metal.

One of the primary challenges is dendrite formation, which can still occur even in solid electrolytes.

Semi-Solid-State Hybrid Batteries

Semi-solid batteries use gel or polymer electrolytes while retaining elements of traditional lithium-ion architecture.

Lithium-Sulfur (Li-S)

Lithium-sulfur chemistry offers extremely high theoretical energy density.

The main engineering challenge is rapid degradation of the sulfur cathode.

Ceramic Electrolyte Solid-State Batteries

Ceramic electrolyte systems are one approach to achieving fully solid-state lithium batteries.

Current limitations include material fragility, manufacturing complexity, and interface resistance between layers.
