The SafeConnect XT90 harness for 2 packs in series lets you connect two identical packs in series to double the total voltage and cell count. The listing gives an example: connecting two 12V 1800mAh batteries with this harness gives a 24V 1800mAh battery.
It uses high-quality Amass connectors, with two female and one male XT90 connectors arranged for series battery connection, and 10AWG cable for heavy current.
The harness is 92cm long, weighs 48g and is black and red in colour.
Series connection: joins two identical packs to double voltage and cell count.
Amass XT90 connectors: two female, one male.
10AWG cable: heavy-gauge wire for high current.
92cm length: reaches between two packs easily.
Black and red wiring: clear polarity colours.
Connecting two batteries in series adds their voltages while the capacity stays the same. Two identical packs, for example two 6S packs, become a 12S pack with the same capacity. The harness joins the positive of one pack to the negative of the other and leaves the free positive and negative for the load.
Only join packs that are identical in cell count, capacity and state of charge, and check that your ESC and motor can handle the higher voltage before you fly. Charge packs separately, and never connect a series harness while either pack is plugged into a charger.
Solder connectors with a clean, hot joint and enough solder to fill the cup, then slide heat-shrink over the joint so no bare metal is exposed. A cold or under-heated joint has high resistance and gets hot under load, which is the most common cause of connector failure. Always check polarity before you plug in a battery for the first time.
High-voltage multirotor setups using two packs
Doubling voltage for compatible ESCs and motors
Large UAV and heavy-lift builds
Power systems that need 12S or 14S from 6S or 7S packs
Field power supply banks
Only use the harness with two identical packs and a load rated for the combined voltage. The connector width is 10mm and the harness is supplied as one piece.
Because the harness carries the full pack current, use it only within the rating of XT90 connectors and 10AWG wire.
