01 /Overview
Product details
Octopus combines a CC-CV charger with a 9-cell (9S) LiPo battery management system, charging from a 37.8 VDC input at over 92% efficiency.
Per-cell monitoring (3.2–4.2 V) with 65 mA balancing and tight 5 mV unbalance control protects pack life, backed by hiccup-mode OCP, OVP, OTP, under-voltage and reverse-polarity protection.
