About this part
The Ri3020HD29 is a rechargeable smart lithium-ion battery pack delivering 10.8V and 8.4Ah typical from nine 18650 cells in a 3S3P configuration, in a package weighing just 284 grams. Impedance Track fuel gauging keeps state-of-charge accuracy better than 1% error over the life of the pack, with results reported to the host over SMBus alongside remaining capacity, run time, cycle count, and alarm status. The pack requests its own charge voltage and current from any SMBus Level II or Level III smart charger, and four on-pack LEDs give operators a state-of-charge reading without powering up the host device. Protection is redundant by design: auto-resettable primary circuits guard against over-voltage, under-voltage, over-current, over-temperature, short circuit, and cell imbalance, with a non-resettable logic fuse and a 15A slow-blow fuse as independent backstops. The pack operates from -20°C to +55°C on discharge, is UN 38.3 transportation tested, and carries CE, UKCA, and FCC Part 15 Class B marking.
