    Cold Weather Storage and Charging Questions Answered

    Just as a data-point, the most recent firmware for the bike (1.0.218) doesn't really seem to solve the vampire drain of leaving the bike in stand-by mode. I left mine for 9 days and it went from 36% to 22%. I don't think it's feasible to leave the bike in standby for off-season storage unless...

    Cold Weather Storage and Charging Questions Answered

    Above on this thread, it was mentioned that the VCU has its own battery, and that is kept charged by the high voltage battery when in stand by. The concern is that if you leave it in hard shutdown mode, the VCU battery could discharge and then you cannot power on the bike at all. There’s some...

    Cold Weather Storage and Charging Questions Answered

    Did you do a hard shutdown or did you leave it in stand by? If it was the latter, then they’ve really fixed that vampire drain issue the bikes originally had!

    Cold Weather Storage and Charging Questions Answered

    Since I've got a couple of weeks to wait before I can ride, I'm leaving mine in stand by so I can measure what the battery drain is like. It will be interesting to compare results. Though ultimately, I hope none of us have to sit around and not ride these things for too long. :)

    Cold Weather Storage and Charging Questions Answered

    I've been following this thread with great interest. I just got my Varg out of storage. It's been tucked away in a heated garage for 5 months. I had no access to check in on it, nor was it on a charger during this time. I put it away before I realized there was a battery in the VCU that was...

    Charging - 220 vs 110

    No generator. I went kind of over-board and did this: https://electricdirtriders.com/threads/my-240v-battery-inverter-track-side-charging-setup.3766/ That said, it's working really well and comes in handy during the off season if there's a power outage. Or at least, that's how I'm...

    Charging - 220 vs 110

    I find it’s handy to have at times. I generally will charge up to 80%-ish overnight and just top up before I leave for the track. At 240V, you get about 1% a minute, give or take. (The EX may be slower since the battery is larger.) At that speed, it's reasonable for me to get home from...

    How Do You Plan To Survive (Battery) the Winter?

    I'll be interested to hear how this goes for you. Generally, Lithium ion batteries can safely discharge at a much lower temp than they can charge at. So assuming you get there with a full battery, I think it'll be fine. I'd guess that by the time you want to charge it back up after doing some...

    New Stark EX Enduro announced, List of issues/unkept promises with current/original Stark Varg

    Sorry to hear that your bike has been such a disappointment. I cannot claim that my experience is universal, but I’ve got 100+ hours and one season riding MX, including plenty of guest riders. I’m an early ish VIN: 3000’s. There’s been a few hiccups like the inner tubes, but nothing...

    How Do You Plan To Survive (Battery) the Winter?

    I rent heated storage at a place near me. It wasn’t really much more expensive than non-heated. I charged my battery to about 40%. Did a full shut down (not stand by) and then disconnected the power switch (connector behind the number plate). My concern is someone might accidentally hit the...

    Formula to Brembo rear brake

    I was thinking about getting the Brembo setup, but I had the fluid flushed as part of yearly maintenance. It’s made a world of difference. So much so that I’m not going to bother with the Brembo setup.

    Regen setting on MX track

    This is a brilliant idea!

    Questions: Track & Trail set-up. Charging & Transport.

    Yeah, one nice thing about going to a track is you just go around in circles. You're never too far from your car/truck/trailer and a top up. I don't ride trails, so I cannot speak to it personally, but I'm told that the battery usage is drastically less riding trails vs MX track, since you're...

    Questions: Track & Trail set-up. Charging & Transport.

    So I can't speak to trail/enduro riding, but at an MX track, I have a setup detailed here that works quite well. It does not have the ability to fill back up on-site via solar. It's just an extra "gas can" that I refill once I get back home. I've got ~85 hours on the bike now. Here's what I...

    Thread Dedicated to Keeping Track of Firmware Versions

    One lovely feature of the new Varg App: We can set a max battery charge percentage and the bike will stop charging when it hits this. I just watched, and it slowly curtailed the charging speed one it hit my limit, probably to accommodate the voltage sag that happens after you stop charging...

    My 240v Battery/Inverter Track Side Charging Setup

    I looked into it, but they looked pretty expensive for what you get. It also wasn't clear if they'd support the 3500 Watts continuous that the Stark charger will use. While my system lacks a certain polish that Anker, et. al. have, I think this worked out a little better in terms of total KWh...

    My 240v Battery/Inverter Track Side Charging Setup

    I'm pretty much always talking about the external battery I purchased from AliExpress. Being LiFePo4, they'll stand up to a lot of punishment. And frankly, if they die I don't care nearly as much. The Varg is definitely not a LiFePo4 battery. They use NMC chemistry cells. Specifically, it's...

    My 240v Battery/Inverter Track Side Charging Setup

    For anyone that’s interested, here’s my setup for topping up my Varg at the track. I didn’t really want to deal with the maintenance and fuel on a gas generator. I got the Varg because I was sick of changing oil and cleaning air filters. :) So I went for an external battery instead. I had...

    do you store the bike in standby mode or completely off?

    This is going to be a bigger question for me in a few months. I put my bike away in heated storage for the winter, (Nov - April usually) but I don't have access to it during that time. I know that leaving it in stand-by uses about 1-2% of battery per day. When I've done a hard shut down, I...
