Can try worcraft. So far i use their cordless products its good and lasting. I have cordless drill, circular saw, small sabre saw, hammer drill, vacuum and angle grinder. So far the vacuum, angle grinder (brushless) and hammer drill is still very good, using almost 2 years already. Battery need to get 2-3 replacements as the old ones kaput, cant repair, hence bought new ones. Cordless drill also, 2 of them i replaced the battery. The tool itself works, is the battery KO. lol. All use more than 1year.

I so far only use Bosch and Worcraft, when Worcraft first came out at my supplier store I tried it, as that time Bosch was quite expensive. And it was the most cheapest comparing to Bosch and Makita. Even now Makita products are expensive. I wont go for that la, haha. Just use the original battery, I wait for promo only buy, since i got so many Worcraft products, oh i also have the grass cutter, but the one using single battery one. I bought during promo i think around RM160/ea i think. lol

I think its not the battery, its the board. But i do not have the expertise to repair the board. I did check with the supplier but they said they dont repair Worcraft battery. lol

When i opened it i think one of the capacitor spoil. need to solder i think. haha.

Haha, not easy to learn leh. lol.

need to know what type of capacitor to buy, not sure about that. haha. and 0 knowledge on electronics. ahha.

hahaha. i do have a drone, an old model, RC One Eye. It was the hype then, haha friend asked me to buy. lel. played awhile then left it there hahaa. still somewhere in my storage haha. Probs will try it out again, to rekindle the spark i had that time haha. my friend now fly drones sometimes with FPV. And do those advertisement for malls etc.
