Part# 11-10835
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

September 15, 2022

It costs as much for tools and supplies as to buy It does not fit in door on Cessna. That should be added in description Requires A&P sign off and u wanted it to be a simple put in hangar open door and hook up charger. Which is actually made by a different company So to hook it up I have about $380 to charge my concord battery Wondering if I should have just bought a new battery The company who makes the kit was very nice but on a Cessna it won’t fit So may have to acquit if it won’t fit I’m not going to pull off the cowling each time And the plane sits more than it flies They could at a minimum for this price put a little solder in the kit Call them on orientation of the terminals as pic in manual though colorful is not clear They will call u back if u leave a message so good in this aspect Looking for another install option.

Works perfect. Keep in mind that you will need to solder the connections that feed into the connector. Other than that it was easy to install and has been working great.

The kit looks complete. It should make it easier for my mechanic when I ask them to install an external connection for my Batteryminder. The Batteryminder manual, however, is a little unclear about whether or not they are still recommending charging a battery while it is still in the plane. You mind want to see if you can read the Batteryminder manual first.

This kit worked great, was easy to install and now I have the peace of mind that my batteries will stay charged. I installed one on my Navajo and a second on my C-150. I wish I’d bought these years ago.

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.
