Applicable string number: 2-24S Applicable battery type: //LTO (ternary/lithium iron/lithium titanate) fully compatible The number of strings applicable to the power supply range: the minimum voltage of the battery pack is 30V, and the recommended value: 10 strings for ternary batteries, 12 strings for lithium iron batteries, 20 strings for LTO batteries Working range of single voltage: 1.0 ~ 4.5V Voltage balance accuracy: 1mv (voltage measurement accuracy), 1mv (voltage balance accuracy) Color: black Material: ABS Equalization : patented equalization architecture flyover capacitance , combined with point-to-point energy algorithm for efficient balancing. Equalizing current: APP custom setting: 1-4A, since constant current and constant voltage technology is adopted, the equalizing current is of battery voltage difference Offline detection: offline detection Under voltage protection sleep voltage: Under voltage sleep voltage can be customized by APP: 1.5-4.2V Static working current: balanced closing 10mA, balanced opening 25mA Product size (MM): L140 x W128 x T22 Whether external power supply is needed: no external power supply is needed, and the whole group is balanced by the internal energy of the battery be careful: Blue Bluetooth status indicator: always on, link successful; Blinking, is broken. Red fault status indicator: normally on, internal fault; Flashing battery detection failed. Green working status indicator: normally on, balanced; The flashing equalization is working. Package Contents: 1 x Equalizing energy device 1 x Flat cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
