Keep Track Of Your Packs On The Trail

Keep_Track_Of_Your_Packs
It’s getting close! As of the time we’re writing this blog, Axialfest 2018 is only a few weeks away and that means attendees are kicking their builds and prep into overdrive to be ready for the epic weekend of off-road action. One comment we’ve seen frequently from drivers is “Can’t wait to pack up my battery packs, turn on my rig and head out on the trails.” Hikers will spend all day on the trails trying out the many courses laid out and some even venture off and find other challenging terrain. This goes on day and night and those long drives will eventually eat through battery packs. Battery changes can be frequent and we’ve seen a number of drivers on the trails with a pack in each hand wondering which one was charged and which is the discharged pack they took out of their rig a few hours ago. So we’ve decided to show you a few simple tips to keep track of your packs so it minimizes your downtime while hiking around Axialfest. These tips will of course work anytime, anywhere so read on to make your RC life much easier.

The answer to keeping track of your packs is simply tags. Using a tagging method to keep track of your packs will make trail time so much more fun. Even for those entering the Altra Ultra 5K where saving time could make the difference in how you place in the event. Here are a number of ways to simply tag your packs so you know what is charged and what is not.

Bread Bag Tag

Start saving those little plastic tags that come on your plastic bread bags or english muffins. These little tags make great ID tags for your packs. Once you’ve collected a bunch, use a black permanent marker and simply make check marks on some and X marks on others. Now you can slip the check marked tags on your charged packs and put the X tags on discharged packs. We also suggest clipping or lightly sanding any sharp areas of the tag hole so it doesn’t harm your battery wire insulation.

Caps

Many hardware stores carry packs of rubber caps for multiple uses. These caps look like your rubber antenna cap, but larger. Find caps that will fit over your specific connector. Find two different colors to indicate charged and discharged packs. The caps will also protect your connector from the rare instance of a short while its bouncing around in your backpack.

Rubber Bands

Good old rubber bands to the rescue. With rubber bands, you can simply wrap them around your charged packs and when you go to install the pack in your car remove the rubber band. Now any pack that has been removed later and does not have a rubber band means the pack is discharged.

Tape

A simple piece of masking tape (obviously green is preferred here) with one end folded over before placing it on the battery can help indicate a charged pack. When you go to install the pack in your rig, peel the tape off and you now know in the future that battery has been used.

Be organized

Being organized and tagging your battery will make your trip much more fun. We urge you to follow all safety precautions outlined in the instructions that came with your battery packs. When traveling by car or out on the trails, make sure your extra packs are stored in safe transport carriers. Many will put their packs in LiPo sacks before putting them in their backpack for a days run. Sure your day should be filled with fun, but safety is always number one. See you at Axialfest.

How To – Program Your ESC For NiMH Batteries

 

Program_NiMH_Batteries

Axial’s Ready-to-Run (RTR) vehicles are true hobby-grade products and, as such, they use sophisticated electronic components. One of the primary advantages to such high-tech gear is adjustability and an area of adjustability includes battery type. Axial’s electronic speed controls (ESCs) are designed to be used with a variety of battery chemistry types and can, and should, be adjusted for the type of battery you’re using.

IMPORTANT NOTE: As a safety measure, Axial uses the LiPo setting as the default setting on the ESC, but NiMH batteries, are often recommended for use with RTRs. NiMH batteries will provide best performance when the ESC is used in NiMH mode.

LiPo batteries must be run with the ESC set in LiPo for safe use. This isn’t optional. When properly set in LiPo mode, Axial ESCs are designed to eliminate the chance of over discharging the battery and permanently damaging it, which is a potential safety issue. As such, LiPo batteries should never be used in any other mode other than LiPo mode on the ESC.

NiMH batteries will work in LiPo mode, but there will be a noticeable reduction in performance that will suddenly become apparent as the pack starts to lose voltage (discharge). This is because LiPo mode has what is called LiPo cutoff or low voltage cutoff. As the voltage drops in the NiMH pack, it is still delivering usable power, but the LiPo cutoff engages and impairs performance. The LiPo cutoff is designed to reduce power to the motor in order to keep the battery at a safe minimum voltage. Let’s go over setting up NiMh mode on the various Axial ESC offerings so you can get maximum performance when using this type of battery.

AE-2. The AE-2 is a brushed motor speed control. While Castle Creation’s Castle Link system can be used to link the ESC up to a computer (availabe as an aftermarket item,) for ease of use, the AE-2 can be programmed manually by using the throttle trigger on your transmitter to indicate yes or or no to selections as you scroll through each option. To get the best performance when using a NiMH, the ESC should be programmed to operate in NiMH mode.

When programming, as a safety measure, remove the pinion from the motor. This will prevent the gears and/or vehicle from moving and causing damage to the vehicle or you. Turn the transmitter on and then connect a freshly charged battery to the ESC. Hold full throttle and turn on the ESC. You will hear four tones from the ESC and then another four tones. After the second series of four tones, release the throttle. The ESC will beep twice indicating you’re in programming mode.

There are three settings that can be adjusted on the AE-3. Each setting, in turn, has a varying number of options. You will use your transmitter’s throttle to select yes (full throttle) or no (full brake) for each option. When you select yes, the next setting will come up. Every time you select no, you will toggle to the next option within that setting. When you select yes or no, wait for a continuous tone and let the throttle go to neutral. If you selected yes, the ESC will go to the next setting.

To change to NiMH mode, you will need to go to the first setting. Remember, LiPo batteries must be used LiPo mode.

Option 1: None (NiMH mode)
Option 2: Auto-LiPo*

Vanguard AE-3. The Vanguard AE-3 is a brushless motor speed control. It comes preprogrammed in the “Auto-LiPo” mode. Like the AE-2, you can use the Castle-Link to program the ESC with your PC, but you can also manually program the ESC with your transmitter.

When programming, as a safety measure, remove the pinion from the motor. This will prevent the gears and/or vehicle from moving and causing damage to the vehicle or you. Turn the transmitter on and then connect a freshly charged battery to the ESC. Hold full throttle and then turn on the ESC. You will hear four tones from the ESC and then another four tones. After the second series of four tones, release the throttle. The ESC will beep twice indicating you’re in programming mode.

There are nine settings that can be adjusted. Each setting, in turn, has a varying number of options. You will use your transmitter’s throttle to select yes (full throttle) or no (full brake) for each option. When you select yes, the next setting will come up. Every time you select no, you will toggle to the next option within that setting. When you select yes or no, wait for a continuous tone and let the throttle go to neutral. If you selected yes, the ESC will go to the next setting.

To change to NiMH mode, you will need to go through settings one through six to get to setting seven, which changes the battery mode. Remember, LiPo batteries must be used LiPo mode.

axial ae-5 esc

AE-5. The AE-5 is a brushed speed control and is by far the easiest ESC to program. To switch from the factory LiPo mode, remove the “jumper” and move it over one position. Not only is this ESC easy to program, it’s also waterproof.

ae-1

AE-1. Axial’s AE-1 ESC does not have a LiPo cutoff. If you use LiPo batteries in a vehicle equipped with an AE-1 ESC you must use a separate LiPo low-voltage cut-off device. Axial does not sell a separate LiPo cut-off device, so the best choice would be to upgrade to an ESC such as the Axial AE-5 (see above), which is extremely easy to program and waterproof.
