1 Product description:
This product is used to charge/discharge three groups of lithium batteries in series, and each group can connect multiple lithium batteries in parallel. It can Withstand continuous charging current 20A, continuous discharge current 40A, instantaneous current below 80A. used During the process, the heat dissipation conditions should be good. If the heat dissipation conditions are not good, please reduce the current usage and do not let the board The has a noticeably hot feeling. During charging and discharging, it has overcharge protection, over-discharge protection, and over-current Protection, short circuit protection. This product can be used in electric drills, sprayers, LED lights, low power reverse Charge and discharge batteries of transformers and other products.
