Winter storage of battery

Winter is coming slowly which is bad for the skating but good for the skiing.
What's the best way to store it to preserve the battery?

 

keep it fully charged, and check it every few weeks, top up the battery or run it for a few minutes I would say

 

Normally you don't want to keep li ion batteries fully charged. But around 60% in my opinion . Keeping the batteries fully charged gives a lot of stress on the battery . Just my experience of RC batteries . With a hobby grade charger you have the option to discharge a battery to a certain voltage . I will check what value this is and report back.
36 V it is as mentioned in the manual.

 

I have a solution... don't store it, use it!!! I'll be using mine as much as I can on the days throughout the winter months...

 

While its correct, Lithium Ion batteries like being at 50% SOC / State of Charge, however, the battery capacity of small battery packs such as skateboards and even electric motorcycles really isn't that much to begin with and it becomes too much work managing this habit while making the product you're using useful. In an electric car there's lots of capacity and replacing this battery pack is way more expensive than replacing the pack on your evolve, so there you do want to be nice to your battery. I've very focused here, on my EV car battery, and keep a close eye on the State of charge and how I use the battery. Other things that stress the pack is of course charging above 85% and discharging below 15%, leaving the battery sit at low SOC for a long time and also completely draining it. Lastly when your below 50% and you demand full power from the pack, that's stressful. Yes I follow these rules for my car and its not that much of a pain since my goal with my car is range and you don't get affected much in terms of being a pain to manage since the pack is so much larger. However you can see this real pain in the ass trying to do all this for your electric skateboard and electric motorcycle. But don't worry, they'll be fine. And in all honesty you'll most likely upgrade the board within 4 years than replace a worn out pack in 7-10 years.

RC cars is a whole different discussion and I wouldn't even try to compare RC batteries to electric skateboards, motorcycles, bikes or cars at all.

Also know that the Evolve skateboard has a BMS (battery management system). This shuts down the battery if the voltage is critically low saving your battery from death, it also manages the balancing of the battery cells. If you don't know what that is, google it. The board needs to be fully charged *and* plugged in for the BMS to balance the battery. Depending how out of balance the board is (gets out of balance if you keep the SOC not at 100% and worse the lower and longer you stay there), you could be sitting on the charger overnight while in full charge or sitting for a couple of days. Another reason to keep your board plugged in. Having the battery fully balance puts less stress on each individual cell and gives you the most optimal performance and range from the pack.

 

I think that you can go for climate controlled storage units. I have heard one of my friends saying about this last winter. He stored his car batteries in such units. Hope you'll find this useful.

 

I left mine at about 80% charge late last year before the snow came - its still there - no loss at all (I spin it up about once a month)
