Can anyone recommend one of those motion detector anti-theft devices that might be good to have? I don't usually leave my bikes locked up for more than a few minutes and am highly paranoid about leaving them in situations where there's any opportunity for theives to strike but I would like to have a device in cases where it's marginal.
I used this thing for a while, but it started shorting out after a few heavy rains and randomly going off: https://www.ebay.com/itm/Anti-Theft-Security-Alarm-110dB-Motion-Sensor-Annunciation-Lock-For-Bicycle-Bike/222668990726?hash=item33d81b2906:m:mG2AxSiZJwo5KaLfgtCTtCA
Looking at this one now, hopefully it's actually waterproof: https://www.ebay.com/itm/Wsdcam-113dB-Wireless-Anti-Theft-Vibration-Motorcycle-Bicycle-Alarm-Waterproo/263445619945?hash=item3d569524e9:g:zWAAAOSwqlRaYQn4
There's also always the GPS option, but I gave up on that too...bought a seatpost with a tracker, then the vendor stopped responding to email when it wouldn't sync via bluetooth to my galaxy s7. Nice, heavy, $100 paperweight.

Ahh, the battery. It turns out em3ev's website says they are out of stock anyway with those ones, waiting to hear back from them. I really like the bottle holder types, and the dolphin types, but em3ev doesn't have them. Lunacycle does, but they are way more expensive. em3ev has them in plastic rectangle form, but I couldn't see any information on attaching it to your bike. I would definitely like a plug and play solution - don't want to leave it attached to my bike. I was hoping the triangle bag would be easily removable, but I have no experience with any battery options.
I can vouch for this Chinese vendor...free "fedex" shipping took longer than I expected (4 weeks!), but the cells were legit and my 52V 11.6AH PF is working great: https://unitpackpower.aliexpress.com/store/1178407?spm=2114.search0104.1000002.19.1bc5cd45QpLYr3
At the price point you're at for battery, I'd say this is probably the best fit: https://www.aliexpress.com/store/product/US-EU-AU-No-Tax-Long-Range-14S-Triangle-Ebike-Battery-52V-20Ah-Lithium-Battery-Pack/1178407_32833734630.html?spm=2114.12010612.0.0.13ffae99hGIQ3u
If you want to ditch the triangle for security/portable charging, this is what I'd probably go with: https://www.aliexpress.com/store/product/US-EU-AU-No-Tax-New-Hailong-52V-16Ah-Down-Tube-Li-ion-eBike-Battery-compitable/1178407_32844147790.html?spm=2114.12010612.0.0.13ffae99LA4PcC
