MFR Model# BM-AIK2A

Overview

This kit provides standard aircraft parts acceptable under 14 CFR §21.9 for a FAA certificated mechanic to fabricate and install a fused, 2-wire harness for connecting an aviation-specific BatteryMINDer® brand of low-current, continuous-duty, maintenance-type battery charger. The finished harness typically has ring terminals attached to the battery relay connecting to a Anderson SB50 polarized plug at the opposite end by up to 6 feet of MIL-spec unshielded 16-gauge aircraft wire, with a 10-amp in-line fuse. The SB50 plus is encased in a 670-420 SB50 Handle Kit which provides a rugged hand grip. An insulating dust cover protects the plug when not connected to the charger. Anti-chafe sleeving is included.

This kit is eligible for installation by a licensed mechanic as a minor alteration under 14 CFR §1.1 and §21.93(a) as it has “no appreciable effect on the weight, balance, structural strength, reliability, operational characteristics, or other characteristics affecting the airworthiness” of the aircraft. No STC, Form 337 submittal or FSDO field approval is required per FAA Order 8900.1 Figure 4-67. A §43.9 airframe logbook entry is sufficient to document this alteration and return the aircraft to service. Also includes a short harness to adapt the charger’s SAE output connector to a mating Anderson SB50 plug. This harness is connected to and remains with the charger. It is not installed on the aircraft.

BATTERYMINDER AIRFRAME INTERFACE KIT FOR FAA-CERTIFIED AIRCRAFT

December 15, 2023

I bought this a long time ago, and finally installed it a few months ago. Cessna 182L with battery in tail. Mounted the plug-in connector up on the ledge above the divider panel , reachable via baggage door, and visible through rear window. Single-hand operation for plug and unplug. I have an older BatteryMinder 14v system and had the temperature terminal ring sensor that the newer systems don’t have. I called BatteryMinder engineer, and the friendly guy said it can be just put inside the cabin dangling wherever. Doesn’t change operating functions or results. The wires can be gently closed in the door, and I have a mouse-confounding funnel on the wire from the Minder box that sits outside the hangared aircraft.

Great product. Very helpful for aircraft that sit for long periods.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Can I build my own quick-connect battery harness for full-time maintenance charging?

For experimental aircraft, the answer is yes. For certified aircraft, there are basically two requirements to be legal. The materials from which the harness is fabricated must be aviation grade, conforming to some recognized quality standard, such as military specifications. The installation on a certified aircraft also requires approval. So long as the installation remains within the FAA’s definition of a minor alteration, any licensed mechanic has the authority to fabricate, install, and approve the installation for return-to-service with a airframe maintenance logbook entry. Our Model BM-AIK2 provides a convenient kit of aviation parts from which your mechanic can easily fabricate, install and approve a charger connection.

Q: Do you have instructions for installing BatteryMINDer connection in my aircraft type?

The instructions that come with our BM-AIK Airframe Interface Kit are generic and will guide the installation on most any aircraft. (see the Documents tab) We also offer a growing list of illustrated installation examples that can be downloaded to show exactly how to install the kit on particular aircraft types.

Q: What size screws should be used to mount the plug?

The hole diameters are .170 so an 8-32 screw would work.

Q: Hi there, the instructions reference a BM-AIK1 or BM-AIK2 charger harness kit. How do we know which charger harness kit we need, or are they both provided? I have a T210. Thanks!

The kit is the BM-AIK2.

Q: OK for a 24 volt battery (two 12 volt Concordes in series?

For full functionality, it is optimum in that situation to use 2 Battery Minders and 2 Interface Kits. Using only one Minder on 2 batteries, you would lose features such as de-sulfating and certain diagnostics--and all it essentially would be able to do is topping off.

Q: Is this BATTERYMINDER AIRFRAME INTERFACE KIT FOR FAA-CERTIFIED AIRCRAFT for 12v or 24v application?

It will work with both voltages.

Q: My mechanic or aircraft manufacturer claims installing the BM-AIK2A is a major alteration and would require an STC. Is that true?

Per the manufacturer: No, the FAA is the sole governing authority on modifications of certified aircraft. The BM-AIK kits have been reviewed by FAA and industry personnel, who agree that its installation does not rise to the level of a major alteration to the aircraft. Only a major alteration, as defined by federal aviation regulations, requires an STC, or FSDO field approval, and filing an FAA form 337 to document the change. It is not the decision of the airframe manufacturer, or type certificate holder. Because it is NOT a major alteration, it is a MINOR alteration, which is within the authority of the installing mechanic to sign off with a simple maintenance log entry.

Q: I incorrectly ordered the 128CEC2-AA-S5 with the interface kit and I have a Teledyne/Gill 7035-28 battery. The S2 is referenced for Gill batteries. What is the difference and can I use the S5

The S5 batteryminder is for the Concorde batteries. The difference between them is the way that is maintains and charges the battery per the battery manufacturers specifications.
