Note that Antigravity "small case" batteries only have BMS circuitry for balance-charging. They do NOT have overcharge and over-discharge protection! Overcharging can be handled by factory VRM/RR. Measure output and verify RR doesn't output more than 15.5v.
Over-discharge protection must be manually done. DO NOT leave bike with lights on and engine not running. Such as using kill-switch instead of ignition-switch. ALWAYS use ignition-switch to turn OFF to prevent ever leaving lights on. This can deeply discharge small battery within minutes and destroy it (even lead-acid batteries).
A LOT of small lithium batteries in market are configured like this, so care must be taken with their charging and discharging to prevent damage.
