JOJOCY Dual Battery Connector 20V-72V, E-Bike Parallel Module Adapter, XT60 Port Design for Dual Battery Pack Switch Balancer
The JOJOCY dual battery connector is designed to help you run two compatible lithium battery packs in parallel to increase usable range and capacity. It supports a wide 20V-72V DC input range and offers selectable current options (20A, 30A, 40A), but it requires careful matching of battery voltage and correct wiring, since the unit can run warm during use.
