One of my main tools is a Makita cordless track saw.
I've switched my main set of cordless tools over to Makita so I can have continuity with tools/batteries.
Makita changed their LiIon battery technology some time in the last few years so, any problems in the past may have been corrected.
The only real drawback to Makita is - - they are pricey....very nice & a huge selection of available tools - - but - you do pay a pretty penny for them.
