    2016 KTM 350 sx-f battery drain issue

    Well being honest... it does depend on Ah Capacity.... the RE-START won't really do the freezing weather well either. But some guys have been using another option. What you need is the biggest Lithium battery in there you can get. So I know some of the companies who do the snowtracks and build the bikes are using our AG-1201 Battery since that is small but much more powerful than anything in its size. So that is about the only one I would recommend for a snow bike.... but again if you have the lighting and stuff I don't want to recommend it because if you over-discharge it and damage it you going to be into a expensive battery and frustrated. So honestly I suggest the Lead if that is what is working for some of you buddies. We have like 3 companies who build the snow bikes or the kits and sell our battery , but as I think they are warning the customers of the potential issues.

    2016 KTM 350 sx-f battery drain issue

    I can tell you that you will have issues for sure with the battery. The problem is MX bikes are not made with enough wattage output to power the extra accessories that you mention and especially the Heated Grip which draw significant energy. Your battery will not be charged properly and you will continually be facing over-discharge and most likely ruining the batteries depending on what you use. Some guys put rewound Stators on their bikes, and I'm sure in some cases they work, but overall it leads to chasing little gremlins down the rabbit hole of never ending little issues. Not trying to be a downer, just saying we know these issues very well and get calls at least once a week with people saying they want to do this and will the battery hold up.... we alway suggest against it because if it not one of our RE-START batteries with th built in low voltage cut-off the guy will be calling back and saying the batteries dead and blame the battery. I actually did it myself years ago and it was sort of a hassle, and the charging system ran at a deficit so the battery was not being kept fully charged. Best start with a system designed to handle this like the Enduro versions.

    Battery failing repetitively

    Hey Roley, We have a Distributor in Aus called Carlise Tires... In Minto.... but as far as NZ it really hard to get batteries in there for us. They aren't allowing us to ship Lithium into there, or else we would try.

    Battery failing repetitively

    Hi guys, if you like the lightweight high power performance of lithium batteries you might want to consider trying one of our "RE-START" models. They have an on board BMS(battery management system) that will not allow you to over discharge the battery so if you do have another underlying problem you can rest assured that this battery will not let itself be damaged but rather put itself to sleep with enough reserve power to still start the bike.

    Best battery for an EXC300

    As you're in the UK I'm guessing that would be "Dirt Bike Show" in Warwickshire as well..? We could easily have some re-seller's there but if not email Chad and he can let you know the best route to go to get you one.

    Alta Motors shutting down?

    That was the biggest bait and switch of all time. They promised these low price Electric vehicles... then Tesla contacts you and says..... "if you want your 3 Car we only have them with the super extras package, so you have to get that one or wait another year" I've talked to 4 people who have done that, some of them left thier deposit a over a year ago, and then heard this, but each chose to get the car rather than wait. Those tactics suck.

    right on the money...as well, all our batteries including the small case and the re-start models have cell balancing built in. If you finds it's something you'd like to further explore please feel free to reach out to us directly or you can email chad@antigravitybatteries.com

    Your absolutely correct a good BMS is the answer to alot of issues... Our AG-401 and AG-801 don't have a full BMS.. but they do have Cell Balancing inside battery itself so you will always have balanced cells. Also the AG-801 is Smaller than the typical Aftermarket Lithium Battery by a little bit, even smaller than our ATZ7 RE-START, but it has more power than any model on the market in its class by about 40%. The reason is it is completely packed with Lithium Cells and has a full 5 "real" Amp Hours of Lithium where as you get about 2Ah to 2.2Ah with any of the competitors, even the KTM Lithium is only 2.2Ah. So the 801 is over double the capacity, and cranking power. I bring this up because you said you want to be able to start on a hillside or other difficult areas. The AG-801 will easily start you bike while in gear with the clutch pulled in. OUr ATZ7 can do that but if it was really cold or the bike was having a bit of trouble starting the 801 would rip start it still. On another note...

    Hi FFMan, just wanted to chime in with a little additional info for you that hopefully helps...people have been using our small case 401's and 801's without a BMS for years in their KTM's so its not necessarily required to have a BMS but one of the biggest problems we ran into in the past was that the batteries would be allowed to over discharge, not as much of a problem for off-road bikes as they generally don't have huge draws or parasitic drains to worry about. but that being said we came out with the RE-START series to avoid that problem all together. So even something as simple as leaving a light on won't lead to your battery draining to the point of being damaged. Plus you'll have enough reserve when the battery goes to sleep to still start the bike with no problem so you'll get peace of mind knowing you won't be left stranded.

    Alta Motors shutting down?

    Freerides are sort of trial oriented..not as good suspension not as beefy of a bike, even their gas varients are just a playbike. The Alta was a real sized and powered MX bike. It doesn't mean KTM knows better than Alta because they are a bigger company. Alta was out there competing and did the Redbull Rhythm, and also did freaking Ezberg... and were doing great except for not calculating the proper distance for the battery change. But that is what this is about, taking your product and racing at the top professional level to prove it's good. I don't think the market can sustain their product, but it was beyond what KTM was doing for sure in terms of a real bike. I'm sure KTM could do something but probably doesn't want to, but a Freeride was not in the same class as the Alta.

    Battery cca

    The AG-801 is great for the extra cranking (240 CA) but our "small case" batteries won't have the space for any other extra components such as the BMS(battery management system)board that goes into the "RE-START" series as the"small case" are the most powerful battery you can get at the smallest size. Typically they are used in a lot of custom applications or instances where the battery is relocated but of course can used in other applications. But again to answer you question, the ATZ7-RS is roughly the same size but just has a little less cranking amps. Still more than adequate to start those 450's though!

    Battery cca

    The ATZ7-RS is rated at 150 CA. Generally you won't see lithium rated in cca as it's a designation designed specifically for lead/acid(cranking on a lithium battery for the time necessary to rate it would generate extreme power and too much heat) but you'll usually see it designated as "lithium, practical, or just "cranking amps" which is comparable. As far as those temperatures go the battery will still work great. The key on really cooler days is to "wake" or "self warm" the battery by drawing off the battery before attempting to turn over for starting. This can easily be done by turning on your lights for a couple minutes or even engaging the ignition(without an actual start attempt) This will warm the cells to give you full capacity and cranking power. If you attempted to start right out of the gate the battery might come off as sluggish but another benefit of lithium is that it would recover pretty quickly vs lead/acid, which once you've exhausted during an attempt would likely not.
