I?d like to solicit personal experiences with people using powersport lithium batteries in their installations. More specifically, Shorai batteries and other batteries with NO built-in bms. I?d like to kindly ask people to keep this thread specific to batteries OTHER than EarthX as doing otherwise seem to inevitably lead to the discussion going into thermal runaway and subsequent deletion by the moderators. Marketing pitches are not welcome. Just builders/owners personal experiences and observations.
So far, based on my research, the following provisions should make such a battery a sensibly safe and economical choice:
? crowbar overvoltage protection and a provision to monitor the voltage in the system
? locating the battery in such a way that it can be vented outside in case of a thermal runaway (engine side of the firewall or inside a sealed enclusure vented outside)
? protect the battery from sources of heat (i note that the popular lead acid battery has a similar operating temprature requirements as a lithium battery and therefore placing a lithium battery in a similar location on the firewall presumably should be acceptable)
I am about to pick a bettery for my installation. I have personal experience running a Shorai battery on my bike. So far, I?ve heard of no dangerous failures of Shorai batteries other than those induced by abuse beyond normal operating parameters or by installations lacking overvoltage protection. I am trying to count every oz in my built and the weight saving of using a lithium battery is very attractive. That and the fact that a Shorai battery is only slightly more expensive than a popular premium lead acid battery.
