Drop in replacement for lead acid battery.
IMPORTANT - PLEASE READ:
These packs self drain slowly due to the internal BMS and LED indicator.
If these packs sit for too long or are discharged too low they will go into a safety mode that requires them to be trickle charged before they can be used again.
