30 Ah of lithium iron phosphate capacity in the Nexus 20L format for powersports and custom-audio builds. Assembled and tested in the USA.
Specifications
- Chemistry: Lithium iron phosphate (LiFePO₄)
- Nominal voltage: 12.8 V
- Capacity: 30 Ah
- Cranking performance: 515 CCA — lead-acid equivalent
- Cell construction: Large-format cylindrical
- Cell balancing: Active balancing
- Automatic BMS cutoff: Not included
- Internal fuse: Not included — external circuit protection required
- Group size: 20L
- Manufacturer SKU: OO-NX-20L
The cranking figure is a lead-acid-equivalent claim, not an unqualified lead-acid CCA certification.
Balancing and installation
Dedicated active balancing transfers energy between cell groups to help keep their states of charge aligned. It does not automatically disconnect charging or output at voltage, current or temperature limits. This base Nexus model has no automatic BMS cutoff and no internal fuse.
Have your installer verify lithium charging suitability, battery operating limits, wiring and appropriately specified external circuit protection. Capacity is not a continuous-current rating, and cranking performance does not establish sustained amplifier output or audio runtime.
Nexus 20L or 30L?
The Nexus 20L has 30 Ah capacity; the Nexus 30L LiFePO4 battery has 45 Ah. The 20L and 30L names identify battery formats, not amp-hour capacities. Choose by the exact application, battery space, terminal arrangement and installation requirements, not capacity alone. The confirmed 20L applications below are watercraft; see the 30L listing for its confirmed Harley-Davidson Touring and other powersports applications.
Battery model references
Comparing your existing battery with the Nexus 20L? These are manufacturer battery numbers used in the 20L reference family. They are comparison references, not alternate Nexus SKU names or automatic replacement approvals. The confirmed Nexus drop-in applications remain in the fitment section below. Check the full model suffix, terminal arrangement, installed clearance, hold-down and lithium charging requirements.

Familiar vehicle names
The confirmed watercraft applications below include selected Sea-Doo SPARK and Fish Pro (FishPro), Yamaha WaveRunner (Wave Runner) FX, VX and EX, and Kawasaki Jet Ski Ultra and STX models. Match the exact year and model in the fitment list; a familiar family name alone does not cover every version.
Additional motorcycle battery references for comparison
These manufacturer reference groups provide starting points for comparing a 20L battery. They have not been added to AVT’s confirmed Nexus drop-in fitment list or bike selector. Grouped source years do not mean every named trim existed throughout that period.
| Motorcycle reference group | Source years | Battery reference |
|---|---|---|
| Harley-Davidson FX / FL Softail 2024 Low Rider S (FXLRS); 2024 Low Rider ST (FXLRST) |
1991–2025 | GYZ20HL / YTX20HL-BS / YTX20L-BS Family-level source range; individual Softail models were not produced throughout every year in this range. |
| Harley-Davidson FXD Dyna | 1991–2017 | GYZ20HL / YTX20HL-BS / YTX20L-BS |
| Harley-Davidson XL / XLH Sportster | 1997–2003 | YTX20HL-BS / YTX20L-BS Yuasa footnote C: hold-down modification may be necessary. This row does not cover 2004 and later Sportsters, which are listed under another battery family. |
| Harley-Davidson VRSC V-Rod | 2007–2017 | GYZ20HL / YTX20HL / YTX20L |
| Harley-Davidson Pan America | 2024–2025 | GYZ20HL / YTX20HL Earlier 2021–2023 models use a different reference family in the guide. |
| Honda GL1800 Gold Wing | 2001–2008 | GYZ20HL-C / YTX20HL-BS / YTX20L-BS The guide lists GYZ20HL-C as an upgrade; preserve its terminal suffix and check the actual connection hardware. |
| Honda GL1800 Gold Wing / F6B / F6C | 2009–2024 | GYZ20L Source model group; each named variant has its own production years. Do not apply this row to earlier GL1500 models. |
| Honda GL1800 Gold Wing / F6B / F6C source group | 2025–2026 | GYZ20HL-C The guide retains a grouped model heading. Confirm the exact current model; GYZ20HL-C is not a spelling alias for GYZ20L. |
| Indian Chief Classic / Chief Vintage / Chieftain / Roadmaster | 2014–2024 | GYZ20HL / YTX20HL-BS Grouped supplier listing; each model and trim has its own production years. Later terminal variants require a separate check. |
| Indian Chief Dark Horse / Springfield | 2016–2024 | GYZ20HL / YTX20HL-BS |
| Indian Challenger / Dark Horse / Limited / Pursuit | 2020–2024 | GYZ20HL-A / YTX20HL-BS Grouped supplier range, not a claim that every model existed in every year. Confirm exact terminals; the -A suffix is distinct. This row does not extend to 2025 or 2026. |
