Calculate total capacity (Ah), maximum current (A), voltage (V) and stored energy (Wh) when connecting multiple batteries in parallel. Perfect for designing battery banks, solar storage systems, UPS setups, and EV packs.
Enter the specifications of each identical battery in the parallel bank.
All values update automatically as you type.
Add the capacity of each battery together. For n identical batteries, total capacity = n × individual capacity (Ah). Voltage remains unchanged in a parallel configuration.
No. A parallel connection keeps the same voltage as a single battery but increases both capacity and maximum discharge current. To raise voltage, connect batteries in series instead.
Sum each battery's maximum continuous discharge current. For n identical batteries, total current = n × individual max current (A). Ensure equal cable lengths and matching battery specs for safe operation.
