## Description

Complete kit for assembling a Makita 18V compatible battery, includes housing, cell holder, connectors, BMS, screws and connection boards, has a level indicator light, 5S2P configuration for 10 18650 cells, overcharge, discharge, short circuit and temperature protections, ideal for restoring BL1830, BL1840, BL1850 batteries.
Makita 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 BMS, the screws and the plates for the connection between the cells.
There is also a light indicator of the battery level.
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.
