Every battery charger ships with a Limited Warranty from Pro Charging Systems, LLC (PCS) covering defects in materials and workmanship, for the original retail purchaser only.

Warranty length depends on your model:

• Marine and most golf cart chargers, including Eagle Performance Series onboard units — 3 years from date of retail purchase.
• Rental market products, model I36154815, and the PS2420 series — 2 years from date of retail purchase.
• Restricted markets (outside the USA or heavy industrial use) — 18 months.
• Sentinel 10 — 1 year from date of retail purchase.
• Certified Reconditioned (CR) units — 1 year from date of retail purchase.

Not sure which applies to you? Check the back of your charger's manual, where it lists the exact warranty term for your specific model.

If a defect shows up, PCS will repair or replace the unit at its discretion. A few things to know:

• You're responsible for returning the charger with proof of purchase, and for prepaying shipping/handling to PCS once a Return Authorization form has been provided.
• The warranty is void if the charger is misused, disassembled, altered without authorization, has its serial number removed, or is repaired by anyone outside PCS's authorized network. Cutting the charge cables or power cord also voids it.
• This is the only express warranty PCS offers; it doesn't cover incidental or consequential damages but does offer charger repairs at the cost of the customer depending on model and manufactured age of unit.

Ready to start a claim? Contact PCS directly by email at tech@pcsdv.com or by phone at 615-471-5300. Have your model number and proof of purchase ready — it'll speed things up.

It depends on what you're charging and how many batteries you're running. Here's the quick breakdown by application:

Marine (boats, fishing, pontoons)

• Professional Series (PS1–PS4) — 1 to 4 independent banks, 15 amps per bank. Built for fresh and saltwater, 12V–48V systems.
• Sportsman High Frequency (SS2HF–SS4HF) — 2 to 4 independent banks, 10 amps per bank, IP67-rated. Works with wet cell, AGM, and lithium (LiFePO4) batteries.
• RealPRO Series (RS1–RS4) — 1 to 4 independent banks, 6 amps per bank, IP67-rated. Works with wet cell, AGM, and lithium (LiFePO4) batteries.

Golf (golf carts, recreational EVs)

• Eagle Performance Series 24V–72V — Portable and Onboard options, 15–25 amps; models available to fit most cart makes and models.
• ES800 Series (ES800-24 / ES800-36 / ES800-48) — Compact 800-watt, waterproof high-frequency charger, less than half the weight of the Eagle line. Great if space and weight matter.

Industrial (lift trucks, scrubbers, utility vehicles, trailers)

• Eagle Performance Onboard Series — Covers 12V through 72V systems, 12 to 25 amps. Built for the demands of lift trucks, floor scrubbers, electric utility vehicles, and industrial equipment.
• Industrial Series (RS1–RS2) — 1 to 2 independent banks, 6 amps per bank, IP67-rated. Works with wet cell, AGM, and lithium (LiFePO4) batteries. Great for drop trailers or material handling applications.

Compatibility depends on the charger line and, for some models, the year built. Here's a breakdown by product family:

• Eagle Performance Series (On-Board): Models equipped with PROView Link (2022 model year and newer) are reconfigurable for FLA, AGM, Gelled Electrolyte, and Lithium batteries. Non-PROView Link models support FLA, AGM, and Gelled Electrolyte only — lithium is not supported on these units unless expressly stated.
• Eagle Performance Series (CH Portable): Supports FLA, AGM, and Lithium batteries via PROView Link.
• Eagle Performance Series HF (ES800): Lithium capable via PROView Link, in addition to standard FLA, AGM, and GEL battery types.
• Sportsman High Frequency (SS2HF–SS4HF): Selectable charge algorithms for FLA, AGM, and LiFePO4.
• RealPRO Series (RS1–RS4): Compatible with FLA, AGM, and LiFePO4.
• Professional Series (PS1–PS4): Standard units are approved for FLA and AGM batteries. Lithium-compatible versions of this line are available in the "AUTO" line — contact PCS for details on lithium-specific models.
• Sentinel 10: Supports FLA, AGM, Gel, and LiFePO4 batteries.
• Zombie: Supports FLA and AGM batteries only. Not lithium compatible.

Because lithium battery management varies by manufacturer, contact PCS to confirm your specific lithium battery brand is approved before charging.

Many Dual PRO models support lithium (LiFePO4) batteries — see which chargers are lithium-compatible for the full breakdown by product line. Because lithium battery management varies by manufacturer, please call PCS at 615-471-5300 or submit a support ticket to tech@pcsdv.com to confirm your specific model can charge your battery brand. Have your charger's brand and model ready for our technicians.

Each LED pattern indicates a different charging state or fault condition. Download the product manual for your specific model from the Product Manuals page, or visit the FAQs and Troubleshooting Support page for step-by-step guidance.

Both our on-board and portable chargers have to see a minimum voltage threshold before they'll come on. This is a built-in safety feature to prevent damage to both the battery pack and the charger. The pickup voltage for each model is below.

1-inch AGX or AGC fuses, rated 20–30A, can be used. To access each fuse, pull apart the yellow inline tube holder on both the positive and negative lead.

• Every charger includes reverse battery protection and no-spark charging as a baseline safety feature, whether it's going on a boat, a golf cart, or a warehouse floor.

Exact certifications vary by model, so the safest bet is to check the spec sheet or the back of the manual for your specific charger.

PCS can repair most of our marine and Eagle Performance charger lines depending on age. Call us or email tech@pcsdv.com to start the repair process. We will need the serial number of the charger to determine next steps. The serial number is located on a white tag wrapped around the AC power cord.
