Shorai not waterproof
From Shorai "the battery is not waterproof". I asked this because of the low battery mounting position and vulnerability to being submerged. The little special charge/balance port is susceptible to water intrusion. Shorai suggested I seal the port with silicon grease around the charge cable. Not exactly confidence inspiring. As to cold weather starting if 48°F is cold then we have other problems. The thing would not crank in the AM @ 48°F just did the reboot thing numerous times. Again that same day after work 50+F failed to crank on the first try. This is the third battery from Shorai and I am on the third charger. From Shorai "we have had some chip problems with our chargers", but they were giving me a good faith replacement battery even though their charger damaged the battery!! To holding a charge for a long time that may be so but not in any bike with a parasitic draw. Take for instance a clock. My bike has 0.008A draw with the alarm activated, 0.006 with just the clock, and that will kill the battery within several weeks.
I am happy for all who have not had starting or water immersion problems with the Shorai battery but for my money the technology is not ready for prime time.
