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.

It is what you need to have to connect the batteryminder properly.

Ive installed this kit on every plane Ive owned. Its a great kit and great quality components. Coupled with a great quality battery tender, your battery life will be doubled!

This kit has been upgraded with new instructions that address the difficulty that some reviewers have had with correctly assembling the fuse holder and the SB50 connector. Also, the adapter harness is now made with a molded handle that makes its much easier to use and provides strain relief for the wires.

I really liked this kit and have installed it for two customers who are happy with it. Installation wise I thought the instructions were very clear.

Andrew is correct, in that the BM-AIK2 Airframe Interface Kit is NOT designed for the high end Model 28252-AA BatteryMINDer. It IS designed for every other aviation-specific BatteryMINDer. The unique aspect of the BM-AIK2 kit is that it provides aircraft quality parts from which a licensed mechanic can fabricate a safe quick-connect battery harness for most all BatteryMINDer maintenance chargers. It was developed in consultation with the FAA and is eligible for installation as a minor alteration, returned to service with the mechanics log book entry. No STC, field approval, or form 337 to file.

I recently installed this on a customer’s airplane. It’s actually better than I expected but could stand improvement. The two ring terminals are silly. It would be a total coincidence if they actually fit your application properly. Plan ahead and purchase the proper sizes. The wiring is ok but would prefer higher quality. They don’t show the splice in the video or the pics. You will have to splice the wire to the fuse holder wire. No big deal, just something that may not be apparent if you haven’t installed one of these before. They did a nice job of researching and documenting the sign off.

This system requires some fabrication to fit your plane. I installed mine in a 182P just behind the baggage close out. I had to make a bracket and adjust it to fit flush so the cover would work and cut a hole In the plastic with a Dremel tool. Turned out very nice. I would recommend this solution.

Yes, connectors having to be soldered somewhat inconvenient but to the guy with the bonanza(Don), next time just hit em with your purse. Ive installed 2 kits and customers love them.

Q&A

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.
