## Description

Complete kit for assembling a Bosch 18V compatible battery, includes housing with support, connectors, BMS, screws, connection boards and level indicator. Works with 10 18650 cells in 5S2P configuration, offers 18V nominal voltage and 21V charging. Ideal for repairs or building a custom battery, 18650 cells are not included.
Bosch compatible battery case, with all the necessary components to make a battery ( 18650 batteries are not included ). With the help of this kit you can make the battery from scratch, having the case, the connectors, the battery holders, the electronic board, the screws and the plates for the connection between the cells.
There is also a battery level indicator board in the kit.
It does NOT include 18650 batteries. Choose the right 18650 batteries considering the current consumption. The use of low-quality batteries will lead to the entry of the BMS into the protection mode due to the voltage drop caused by the high internal resistance of the cells or their dubious quality. Completing the battery requires a spot welding machine .
We do NOT recommend the purchase of the kit by people without clear knowledge related to the assembly of battery packs.
Check that the voltage of the used cells is identical before inserting them or putting them in parallel. It is recommended to keep the used cells in parallel, with almost equal voltages, for a minimum of 24H to balance them, before being mounted.
