To connect in series or /and parallel, batteries should meet the below charging/ discharging voltage). As there are subtle differences in the conditions: a). identical batteries with the same battery capacity (Ah) and BMS (A); b). from the same brand (as lithium battery from different brands has theirspecial BMS) c. purchased in near time (within one month). 2.Restriction for parallel and series connection: 12V Battery: Up to 5 identical batteries for serial connection up to 60 V and no limit for parallel connections. 24V Battery: Up to 3 identical batteries for serial connection up to 72 V and no limit for parallel connections. 36V Battery: Only support to connect in parallel 3.Two necessary steps before connecting: These two steps are necessary to reduce the voltage difference between batteries, and through these, the battery system can provide the best of it in series and/or parallel.Step 1: Fully Charge the batteries separately.Step 2: Connect the batteries one by one in parallel and leave them together for 12-24h. And then you can connect your batteries in series and/or parallel. 4.Or if you need to load and unload them together, the following steps should be taken:A: Fully recharge the batteries separately before the first connections.B: Disconnect the connections among the batteries and recharge the batteries separately once a month. 🏠 RETURN The customer is entitled to return the goods within 30-days after receipt of the goods.
