Victron Energy Battery Indicator Eyelet M8, For Blue Smart IP65 Chargers, 12V Lead-Acid, 30A ATO Fuse

Overview

The Victron Energy BPC900120114 is a Battery Indicator Eyelet M8 for Victron Blue Smart IP65 and Blue Power IP65 chargers, giving a quick battery status readout through an eyelet lead that can stay connected at the battery. It is made for 12V lead acid batteries only, including flooded, GEL, and AGM types, and it uses M8 eyelet connectors with an inline 30A ATO fuse.

This accessory is useful on boats where the charger lead is connected and disconnected often, such as a house battery bank, starting battery, tender battery, or dockside maintenance setup. The indicator helps show whether the battery is ready, can be charged, or needs charging, without opening up the battery compartment longer than necessary.

Key features

• Works as an accessory lead for Victron Blue Smart IP65 and Blue Power IP65 chargers.
• Suitable for 12V lead acid batteries only, including flooded, GEL, and AGM battery types.
• M8 eyelet connectors suit battery posts or studs that accept M8 ring terminals.
• Inline 30A ATO fuse helps protect the DC cable run close to the battery connection.
• Indicator lights show battery condition: green for 80% to 100%, orange for 60% to 80%, red for 40% to 60%, and no light below 40%.
• 6V to 15V operating range with 0.9mA back current drain.
• 0.3m cable length with 3.3mm2 cable cross section, equivalent to AWG12.
• IP65 protection category suits charger connections used in sheltered marine locations where spray and dust are common concerns.
• Compact 22x18x55mm indicator body keeps the status display easy to place near the battery or charge connection point.

Installation and setup

The M8 eyelets are intended to be fitted to the battery terminals or to suitable battery connection studs, with the inline fuse positioned as close to the battery as practical. Once installed, the quick connector lets the compatible Victron IP65 charger plug in without using temporary clamps every time the battery needs maintenance charging.

On a boat, this setup is especially helpful where the battery is inside a locker, under a berth, or in a compartment that is awkward to access. The cable length is short at 0.3m, so the indicator should be planned around the battery location rather than routed across a long distance.

Compatibility and fit

This indicator eyelet is for 12V lead acid batteries only. It should not be treated as a general battery monitor for lithium systems or as a universal charge-state display for other charger families.

The M8 eyelet format is the key fit point to check before purchase. It matches battery posts or bus connections that accept M8 ring terminals, and it is not the right choice when the installation needs a different ring size, spring clamps, or a panel-mounted indicator.

Use cases on board

This is a good match for boat owners who use a Victron IP65 charger for periodic dockside charging, winter layup maintenance, or keeping a starting or service battery topped up between trips. The status light gives a simple check before heading out, which is useful when the battery compartment is not in plain view.

For small cruisers, fishing boats, tenders, and sailboats with conventional 12V lead acid batteries, the eyelet lead keeps the charger connection consistent and reduces the need to move clamps around in tight spaces.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
