Feature: 1. Multistrand Silicone Cable: This parallel charging board can support up to 4 groups of 2‑8s batteries of the same type and number of nodes. Balanced port output line adopts 22awg multistrand silicone wire. 2. Convenient Operation: Gold plated gasket and thickened PCB copper foil are used to support load current up to 35A. Avoid the tedious operation of changing batteries for multiple charges, which is very convenient. 3. Time Saving: Single group charging needs four times balancing, using parallel charging plate only needs one time balancing, the average voltage difference between parallel cells is smaller after weak discharge, effectively reducing charging balancing time. 4. Balanced Charging: When four groups of cells are connected in parallel at the same time, they can be balanced at four times the original single charge current. 5. Prevent Circuit Meltdown: 40A fuse is set between two groups of batteries to prevent circuit meltdown due to excessive battery pressure difference. Specification: Item Type: Parallel Charging Board Material: Plastics, electronic components Size: Approx. 12 x 7.1 x 2.6cm / 4.72 x 2.8 x 1.02in (not including the connection cable) Application: For 2-8S lithium battery.
