So far this is working great for my motorcycle. It never failed to start with my old battery, but sometimes it would crank slow for a second but still start, but when it would do that the clock on the instrument cluster would reset. So far that has not happened so this new battery seems to have fixed that.

See my Amazon video but I'm ultra impressed with this first offering with sodium ion tech still advancing. For those that couldn't find a way to make a SMALLER battery fit into a bigger battery bay, I've addressed that in my video. You DO NOT need a special charger for these. Your standard OHV charging system and older non-smart vehicle's 12V charging system will charge it just fine. Acoucou just needs to release a 300-350 CCA Powersports battery in the same footprint. There's plenty of space to stuff more cells into the existing battery enclosure.

I got the box and thought I had been scammed. Easily 1/10 the weight of a lead acid battery. I wish the terminals were a little more standard, but being threaded and solid vs wrestling with that dang small nut that typically goes inside I'll take this one any day! Can't say how it works yet, but it was at 95% on my charger when I plugged it in. I have a quad that's been sitting for a several months that will go back into plow duty and heavy use on the winch. It will be good to see how it works.

I’ve been using this sodium battery in my Arctic cat for a couple months and seems to be a real win every way. It’s supposed to have a longer life, but I guess we’ll have to wait and see.

It's also very small and very light weight, making it great for all kinds of projects. If temperature really doesn't affect it much, and it charges ok over solar, then I'll probably invest in more Sodium-Ion batteries to start replacing my lead acid.

These are already a better deal than Lead Acid, one purchase to last a decade and you have the added benefit of having more usable power if you get an exact AH rating replacement. (When compared to the 3-5 year lifespan of Lead Acid, Na-ion have 2-3 times the lifespan.

The Acoucou Li-FePO4 battery's BMS was one of the key reasons I chose it. The BMS's intelligent protection features ensure that the battery is in a safe state at all times, protected from overcharging, over-discharging, over-temperature and other problems. This gives me great peace of mind about the safety of the battery, making it an ideal choice for my solar system!
