Hubble AM16+ or Freedom Won LiTE 20/16: compare the warranty behind the battery

A battery warranty deserves the same attention as its price and storage capacity. The useful question is what the manufacturer covers, under which conditions, and what happens if something goes wrong.

The Hubble AM16+ and Freedom Won LiTE Home 20/16 show why the headline needs unpacking. Both have ten-year wording, but the cover differs. This comparison concerns the low-voltage LiTE Home 20/16, not its HV or LiTE 2 namesakes. Keep the documents supplied with your particular battery; an online revision does not establish the terms of an earlier purchase.

The linked original LiTE model sheet is marked EOL (end of life). Confirm the generation and applicable terms for any unit offered; the names alone do not settle that question.

Compare the actual promises

The table uses Hubble’s linked AM16+ warranty and Freedom Won’s currently linked LiTE guarantee, released 15 August 2025. Material document conflicts are explained below.

The two model names do not mean equal capacity

Hubble’s brochure states 16.1 kWh nominal energy. Freedom Won’s sheet states 20 kWh total, with 16 kWh at 80% depth of discharge. Those are different descriptions of capacity. Compare the energy available under the proposed operating settings, alongside power limits and reserve requirements. A model number alone is a poor basis for a quotation. See the AM16+ brochure and LiTE Home 20/16 sheet.

For your installation, ask the supplier to write down the expected usable energy and the loads behind the estimate. Keep a distinction between how much energy a new battery stores, the reserve you choose to leave, and the minimum capacity covered later in its life.

Unlimited cycles still comes with conditions

Hubble requires internet connection within three months of installation, then continued connectivity. Remaining disconnected for three months after its first notice reduces battery cover to three years. Its terms require operation below 50°C; a recorded internal temperature above 55°C voids cover. Mixed-brand interconnection and unauthorised opening are excluded. Read the monitoring and warranty conditions.

The AM16+ manual also requires a full charge at least weekly for balancing, qualified installation and appropriate inverter settings. It restricts unauthorised third-party BMS interfacing. Have the installer confirm the approved communications arrangement for your exact equipment.

Our practical advice: agree who receives monitoring alerts and who responds when connectivity fails. A functioning inverter and a functioning internet link are separate things. Include the router, data connection and handover access in the plan, rather than discovering a monitoring obligation after installation.

Freedom Won has two performance tiers

Warranty cycles use 80% DoD, counted pro rata. Annual use is limited to one tenth of the applicable allowance; average daily cycling is 0.5–2 cycles. Each tier has heat-duration conditions; alternate cover is conditional too. Read the performance conditions.

This matters when someone converts a cycle count into years or megawatt-hours on a sales sheet. Usage, aging and the warranty’s counting method belong in that calculation. We would ask the supplier to demonstrate the proposed duty against the applicable tier, rather than treating a large cycle number as an unconditional energy allowance.

The warranty has changed over time

There are two separate questions: which battery generation are you buying, and which warranty edition applies? The LiTE range spans multiple versions, and its published warranty wording has changed over time. Keep the edition issued for your purchase with the quotation and invoice, and get any uncertainty confirmed in writing. An end-of-life model label does not by itself tell you whether an existing warranty remains valid.

• September 2019 revision, updated March 2020: ten years or 4,000 cycles, whichever comes first, with a 70% capacity threshold. Its version notice specifies manufacturer purchases from 1 September 2019. Read that edition.
• August 2022 edition: ten years or 4,000 cycles, whichever comes first, with a 60% threshold. It specifies manufacturer purchases from 1 September 2022 and directs earlier purchases to preceding editions. Read the version notice.
• 15 April 2024 release: ten years or 6,000 cycles under standard cover, or ten years or 4,000 under alternate cover, whichever comes first; a 60% threshold. We reviewed two retained manufacturer copies circulated under May 2024 filenames. Their warranty wording matches, despite different branding. Neither states a purchase-date boundary.

The changes go beyond the headline. The reviewed April 2024 standard tier has a 0.25C charging ceiling and internal-temperature duration limits of two hours at 25–30°C, 30 minutes at 30–35°C and one minute at 35–40°C, averaged daily over the warranty period. Those differ from the August 2025 terms discussed below.

This is a partial document history, not a complete archive or a decision about an individual claim. The April 2024 entry uses retained manufacturer PDFs; their former public download was unavailable when reviewed. Do not assume a later edition changes an earlier purchase. Ask the seller or manufacturer to identify the applicable terms for your unit in writing.

The current document set needs clarification

Some differences reflect historical revisions, but the published product sheets and guarantee files still need care. The linked June 2024 model sheet says 70% capacity for warranty and 0.25C charging. A May 2025 sheet uses 60%, describes terms for sales after 1 April 2024, and retains 0.25C charging. The other August 2025 guarantee also says 0.25C charging.

That other guarantee’s standard tier allows daily averages, across the warranty period, of up to three hours at 25–30°C, 30 minutes at 30–35°C and five minutes at 35–40°C internally. Higher temperatures invalidate that tier. A warm KZN battery location deserves attention before purchase. See the temperature clauses.

The currently linked guarantee’s standard tier instead specifies 0.5C in charge or discharge, with a duration qualifier. Its portal-registration paragraph refers specifically to LiTE 2 despite listing the original LiTE models. See the current document.

Ask Freedom Won or the supplying seller to confirm the applicable capacity threshold, current limits, tier and registration requirements in writing against the serial number and purchase date. Do not change charging settings on the strength of the more generous document. A version date alone does not resolve conflicting clauses.

Read the claim route as carefully as the cycle count

Hubble requests the original invoice and installation compliance certificate. The customer arranges transport; unsuccessful claims can attract an assessment fee. Unrepairable batteries receive prorated treatment. Hubble claim procedure.

Freedom Won can service, replace with a similar new or used unit, or augment capacity. Transport and reinstallation are excluded if return is requested. Qualified installation, payment and tamper conditions apply. Freedom Won general terms.

Neither description means an immediate new battery delivered free of every associated cost. Before buying, ask who opens the claim, what evidence is needed, where the unit goes and which costs you may carry. Plan how essential loads will be supplied while the battery is unavailable. Also check insurance for external damage and the installer’s responsibility for workmanship.

Choose the battery and the support plan together

There is no useful blanket winner here. Hubble’s uncapped cycling headline must be read alongside connectivity and electronics cover. Freedom Won’s published capacity promise must be matched to a confirmed document and an installation that meets its conditions.

Our approach is to put suitable equipment, local advice and support, and a clear manufacturer escalation route together. Ask who can diagnose a battery-management fault, support firmware issues and approve any changes. Agree who receives alerts and keeps the operating records. Training, repair arrangements and access to the manufacturer’s engineering team belong in the buying decision.

Send Thanda your inverter model, battery location, intended daily use and existing equipment. We can help identify the questions to settle before ordering. For Freedom Won pairing, its integration guide explains that communications, voltage and power compatibility all matter; a shared connector is not enough. Leave the purchase with the approved settings, commissioning record, serial-number photographs and applicable warranty saved somewhere you can find them.
