Frequently asked Questions about EarthX Lithium Batteries
The following is a list of the most frequently asked questions. However, if you have a question that does not appear on this list, please contact us at (970) 674-8884.
This battery comes with advanced technology to protect it from over-discharge, the number one killer of all batteries. If your battery reads near 0 volts, the over-discharge feature has been activated, thus your battery must be charged. If you left your lights on, key on, have a faulty stator, or have a parasitic drain this can easily happen. Our BMS is designed to disconnect the flow of current in the event of over-discharge (internal disconnect switch is opened). Many smart chargers will not attempt to charge a low voltage battery (below 9V). If this happens, there are several ways to charge the battery.
- The easiest way is if you have the Optimate lithium charger. Simply connect the alligator clips first, plug in the charger next, and the save mode will come on and start charging it.
- Another method is to connect your charger to the EarthX battery as normal, then put either a jump pack or another 12V charged battery in parallel with the EarthX battery so the charger will read it’s voltage and engage. Once the charger sees voltage it begins to charge as normal. After 5-20 seconds you can remove the jump pack or jumper cables (being careful not to disconnect the charger). Recharging this battery from the depleted state can take from a couple hours to overnight. To watch a video of how to do this, go to: http://www.youtube.com/watch?v=6o-YYpy9hYU
BMS reset: Step 1: connect the clamps to the battery. Step 2: plug the charger into the wall.
If the charger is already plugged in, unplug it from the wall, wait 3 minutes, and then put the clamps on the battery and plug in. It can take up to 3 attempts to reset the battery depending on how discharged it starts at.
Please read the detailed section on this topic under BATTERY CHARGING section, http://earthxbatteries.com/our-batteries/battery-charging. In the event you have to charge the battery, do not use a charger that has a de-sulfate mode; an automatic de-sulfate mode; or a charger that will pulse above 15V! This will void the warranty and damage the battery. Use any “modern” lead-acid battery charger or Lithium battery charger (LiFePo4) that does not pulse above this level (15V). By “modern” we mean a charger that was built in the last 10 years that automatically turns off when the battery is fully charged (based on volts). If you are unsure how high the voltage goes with the charger you are using, use a voltmeter to check the voltage while charging so you do not exceed 14.6V.
Most of the time, it means you need to charge the battery as it is at a low charge level but it could mean several things. First thing you need to do it put a voltmeter on the battery, if the voltage is less than 13.28V, the LED light will flash to let you know to charge the battery. If the voltage is above 13.28V and flashing, then you could have a weak cell /a cell out of balance/or defective cell and you need to contact EarthX for a warranty coverage if it is less than 2 years old. The LED will also flash if the voltage is too high, above 14.6V. If the light is solid and remains on for more than 10 minutes, then it is an indication of a BMS electronics problem and contact EarthX.
|LED Light||Voltage||Possible Cause||Recommended Action|
|Continuous Flashing Light||Less than 13.2V||Battery over-discharged (due to faulty charging system)||Charge battery. Once charged, the light will stop flashing.|
|Continuous Flashing Light||Less than 13.2V||Weak or failing cell||Charge battery. If voltage drops below 13.2V within a few days, discontinue use.|
|Continuous Flashing Light||13.2V-14.6V||Weak or failing cell||Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.
|Continuous Flashing Light||Greater than 15.2V||Over-charging (due to faulty charging system)||If in flight, shutoff charging system immediately. Aircraft over-voltage protection is recommended (i.e. crowbar circuit)|
|Flashing Light (short periods)||13.2V – 14.6V||Cell to cell charge levels are not balanced||May come on briefly during periods of high current charging until the cells are automatically balanced. Try charging with a plugin charger, like an Optimate Lithium charger.|
|Solid Light than remains on||Any voltage||BMS electronic issue||Discontinue use. If in flight, this is not an immediate issue unless it is in conjunction with a charging system failure.|
|Solid Light that turns off||Any voltage||Short Circuit protection was activated||Nothing needs to be done.|
If a battery does not seem to charge or perform as well as it once did, it may be for one or more of the following issues:
- There may be a problem with the charging system. While the charging system is in operation, it will begin putting out approximately 13.8 -14.7 volts.
- The vehicle electrical system may have a short circuit or current drain
- The terminals on the battery are not properly tightened
- There may be a problem with the battery itself so if you have verified that it is not a parasitic drain, and the battery is losing power within 1-7 days, then contact EarthX. Do not continue to attempt to charge or use a battery that will not hold a charge as it might indicated cell failure and continued use can cause cell rupture, smoke and even fire.
- Never leave the battery or the vehicle unattended when recharging it.
- When charging a battery, place it on a non-flammable, and remove any flammable items nearby.
- Unplug chargers from the battery or vehicle always after the battery reaches full charge.
- Disconnect chargers when not in use.
OMG!!! You sold me a battery for my RV-8A at the Northwest Aviation Conference in Puyallup, WA. I put it in my plane a few weeks ago but the weather did not co-operate until today. What a difference! My starter does not whine anymore and it cranks way faster! Also, I still have not lost […]
Recently purchased and installed an ETX680C for my experimental plane. The 680C replaced a Ballistics Performance EVO2 battery. Your battery is FANTASTIC. There is an amazing difference in cranking performance–I can almost taxi my aircraft when just running the starter!
Questioned myself for buying such a costly battery, however it has been one of my best decisions. This battery has performed exceptionally well and I will continue to upgrade to these Lithium batteries on all of my sport equipment!
The weight loss on my bike was felt immediately. Feels like a have a smaller bike now. Still can’t believe how light weight and strong starting ability. I’m thoroughly impressed. Hope it can hold out for the long run. Very happy so far. Install took a little TLC by bending some loop connectors but battery […]
By changing to this battery in my airplane, I shaved 10 lbs off the forward area and gave myself a far better battery. Easy fit too.
Twice the CCA’s at less than 1/3 the weight. Great product and great company!
Purchased the ETX900 for my 3300 Jabaru aircraft engine in my Zenith CH750. The new battery spins the engine significantly faster, allowing for starting the engine without preheating every time (anytime it was below 60 degrees F) What a difference it made and saved me just over 10 pounds. It’s worth the price.
After flying all weekend I must say I am impressed with this battery (ETX 900). My Odyssey PC 925 always worked well until recently with 4 years of use it started turning the prop a bit slower each time during start.
Your ETX 900 turned my engine and prop (IO-360, C/S) faster than I’ve ever seen […]
Greetings from St Louis,
> I just purchased and installed an ETX 900 in my Vans RV-4. I have an IO-360 engine with a constant speed prop so I need some good cranking amps. Due to weight and balance considerations the battery is mounted just behind the back seat in the baggage compartment. The previous […]
Since receiving the EARTHX battery. . .moments before I left for a Mid-East Hare Scramble. . .I have climbed from 188th up to 38th overall finish.
Your product lightened my gas bike. . .made it start better and faster. . .and my clutch went out the first race with the EARTHX. . .and I would have […]
I purchased an ETX900 for an experimental aircraft. For 3 days I cranked on the motor and finally figured out I had a broken wire which stopped the engine from starting. The battery turned the engine over without hesitation and never needed charging. I was impressed with the performance of this light little battery!
Wow what a great customer service ! Your response was so fast and helpful.I always liked the performance and the quality of your battery, but now i really love your customer service ! Thank you so much i’m an happy customer !!!
EarthX, I’m speechless. Please let me know how I can sing your company’s praises most loudly. I can’t recall ever having such prompt and wonderful customer service!
I have been enormously pleased with the battery. It is light years more powerful than the lead acid OEM battery.
Hi there – thought you might like to have a picture of our Glasair Sportsman for your website. We’re happy ETX680 users. Can’t get over the cranking power from such a small and lightweight battery – awesome.
Thank you EarthX,
I have, and will continue to recommend EarthX batteries to my friends and colleagues. Its not always about the point of sale, but how you are treated after the purchase that is equally important . This company has a firm grasp of this and I thank you!
The battery arrived last Wednesday here in Australia and has since been installed in my 990 KTM bike and everything works as it should. The starter motor has never cranked so strongly so I am one happy camper! As for your customer service you have gone above and beyond and I’ll definitely buy my […]
You guys are Awesome. You guys are great. Your customer service is really appreciated. Your product, although I have already done so, will be promoted highly among my off road riding friends and family.
By the way, your batteries are AWESOME. I’ve probably accumulated an hour of cranking time with all the troubleshooting, timing, and tuning…not to mention all the gear swinging and running of avionics while I sit there endlessly programming things. They ROCK. I never have to worry or think about them–they just work perfectly.
Best customer support/service in the market. Prompt precise response to my questions and solutions to my problem. My hat is off….Congratulations. Keep up the good work. I waited 6 months to use the little ETX12B until my lead acid battery died and when it finally did, I replaced it and my bike’s motor started […]
EarthX, thank you so much for all you all your help.Received the battery today, installed it in my quad turned the key fired right with a roar.Customer service is paramount in keeping your customers happy. You went beyond the call. Kudos to you.Will highly recommend your product to my friends who have bikes n quads […]
