Both Shorais I have have been great, and they are true Buell enthusiasts there

The ones that sat in the EBR's for several years drained to 0 didn't do so well, and even though you can use a normal charger, you should use their specific one to balance the cells. I hate having to have that specific charger, but with 2 bikes it aint so bad...

Most newer tech Li-ion batteries have that cell balancing circuitry internally now, so thats better. Battery tech moves at the rate of electrons! (Sorry for the crappy nerd pun)
