There is a thread on Shorai batteries elsewhere in this forum. This really doesn't belong here, but I'll post it to answer questions entered previously.
The Shorai is not adversely affected in any way by heated gear. I use it all the time from late summer on up here.
A battery is a battery. It's an electro / chemical storage device. In a motorcycle or car, it's designed mainly to be a starting device and a storage device, less so. Without the alternator supplying sufficient power any load on it will drain it the same way, based on current demand and battery capacity. The only real difference is that the Shorai's lower safe operating voltage is a bit higher than a lead / acid's but the Shorai starts at a higher resting voltage, (approx 13.6 volts) and has greater capacity, making it take longer to reach the lower point. It can also recharge far faster than a matching lead / acid as it has a higher rated charge current capacity. For mine, that's 18 amps.
One thing to note... Those ST1100 owners still using the permanent magnet alternator could adversely affect the Shorai battery as the speed of the alternator at idle combined with what loading you have on it may drop the alternator output below the safe minimum voltage of the Shorai, (12.4 volts). This is not an issue with the 40 amp alternator.
