This is our newest Plug-and-Play version of Madhacker's BMSOne V3. It can be used on any Ardupilot vehicle, not just Solo and supports batteries 2S-6S, any capacity, any chemistry, and automatically senses the number of cells. *3DR Solo does not support 2S, 3S, or 6S.

*The BMSOne V3 is compatible with ArduPilot versions 4.4.1 and later, and all Vehicle types.

*The BMSOne V1 and V2 (no longer available) are compatible with all ArduPilot versions and all Vehicle types, including original 3DR Solo Stock firmware.

The V3 supports up to 3 battery profiles that can be selected using a button on the BMSOne. Pressing the buttonbcycles through the three profiles in a loop. The led blinks to indicate which profile is selected.

For Solo it can be used to plug a common off the shelf 4S or 5S battery (XT-60) into a 3DR Solo and have battery telemetry as the Solo normally would. (Yes 3DR Solo flies fine on 5S with the Stock gimbal and GoPro) There are 2 PnP variations available and a non-PnP DIY option as well.
1. External variation snaps onto the battery tray providing a flat deck for the battery to sit.
2. Internal variation is mounted inside the GPS bay and sits underneath the GPS unit.
These variations have connectors pre-installed. No soldering required. The non-PnP has no connectors soldered.

At purchase there is an option to select what battery type will be set to default when shipped. The profiles can be re-programmed easily via its USB-C connector using a terminal software like TeraTerm.

As the JB/BMSOne itself is a PnP device there are some things to consider before making your purchase. The BMSOne profiles can be programmed for your specific battery parameters and performance ratings. The units can be reprogrammed following the instructions here. Please consider the following:

1. To use with Li-ion batteries YOU MUST CHANGE Arducopter BATT PARAMETERS as the Li-ion packs that the BMSOne is configured to has different output characteristics. Refer to the Parameter Setup tutorial at the end of this document to guide you through the parameter update procedure.
UPDATE: There is a package available in Solex that can make the necessary changes for you. There is also a package to change it back to default settings for Lipo use.

RECOMMENDED: Li-ion batteries need to be able to supply 30A continuous current to fly the Solo safely.

2. To use with 4S Lipo batteries like the Tattu 4S 5200mAh 35C there are NO PARAMETER CHANGES REQUIRED. Just make sure the battery you use has similar characteristics. If parameter changes were previously made for Li-ion packs you must change them back before using Lipo again or the capacity percentages will not be correct.

3. To use with any 5S batteries YOU MUST CHANGE Arducopter BATT PARAMETERS appropriately for the different voltage range.

4. It is HIGHLY recommended that you use an aftermarket battery charger to recharge and maintain your batteries. A Solo charger will only charge 4S batteries. The JB/BMSOne can be used with the OEM Solo charger but will NOT provide balance charge or storage discharge, and extra care must be taken not to plug the Solo charger in wrong which can result in a fire.
UPDATE: There is a balance charging device made to work with the Solo charger on 4S batteries. See here: https://jonbrotherton.fws.store/product/solo-charger-balance-adapter

5. Always unplug both connectors of the battery from the BMSOne completely when not in use.

**This is considered a modification to your Solo. Using this is fully at your own risk. Please read all available information and make sure you understand before using any mod.

The proper order for plugging in the BMSOne is:
1. Connect the BMSOne to the Solo.
2. Connect the balance lead.
3. Connect the main power lead.

The JB/BMSOne a cooperative collaboration between the creator of the BMSOne universally known to the Arducopter world as the Madhacker, Mike Lione, Jon Brotherton, and E. D. The primary focus of the JB version is to provide a Plug n Play version of the v2.3 BMSOne that ships pre-configured for use with your choice of Lipo or Li-ion Batteries (sold separately) in a case to protect it, equipped with the proper connectors to simply plug it into the Solo and battery with a ring strap to secure them in Solo battery bay.
