Build Flashlight for 18V Bosch Battery

I have been using this type of flashlight for a year, and it is pretty easy to use. That's why I made this video to show you all.
This flashlight has 3 modes: very bright, normal light and flashing light. With this battery (20V 6Ah 120WAh), we can use 6 hours with very bright mode, 17 hours with normal light mode and 12 hours with flashing mode.
BOSCH 6.0 Ah 20V Li-Ion
- Voltage 18V ~ 20V
- Capacity 6Ah
- 10 cell of lithium-Ion 18650
Lithium-ion battery cell
- Brand model: LG INR18650HG2
- Standard capacity: 2800- 3000mAh
- Rated voltage: 3.6V
- Charging voltage: 4.2±0.05V
- Maximum continuous discharge current: 20A
- Discharge cut-off voltage: 2.5V
- Weight: Max.47.0g
- Size: Max.18.2×65.2 mm
- Charge and discharge times: 500 times
I hope you find this video useful and enjoy it!
Furthermore, I am happy to receive feedback, suggestions to improve myself.

[@thebeast7690]

hey mr gear show, can you make a video on how to make a diy spot welder?

[@topeye4202]

Good Job! :D I allways use the Makita 18Volt standard which is widely spreaded and you get all kind of fairly good knock off tools, adapters, chargers, Battery housings, BMS boards for good prices. This Makita 18V standard will last forever, unless all others which are constantely changing and meanwile all have chips which make it difficult or impossible to renew the 18650 cells by your self.

[@gear_show]

Thanks for the tips!

[@topeye4202]

@@gear_show Thank YOU! : ) , I will make a similar Flaslight as you, but with a 72W three wire round LED spot, which have a yellow round ring LED and white LED's in the middle (xinled 4 inch 72w) and switch them separately with two switches. This way I have a energy save mode with nice yellow light and a bright mode with the others.

[@deepmehra6606]

Wow nice good job I really like this video please sent me this one keep it up bro thank you 😊

[@blasianboomboom2006]

Another quality product from “Small Fart Child”.

[@roberts1938]

Maybe you have an idea how to resurrect the Makita battery, which has a chip that prevents the battery from being recharged after a certain number of use cycles, even though the batteries are still functional. They do this supposedly for security reasons, although everyone knows that it's really about maximizing the company's profits. Do you have any way to solve this problem???

[@trevormurphy7041]

I love the video up to the point where you’re building the flashlight part you basically got a store-bought battery I would’ve re-purposed some old antique flashlight by putting some New Age parts inside it would’ve been cool to use an old brass fresh light other than that great video

You should have put a strobe/flashing warning for anyone who is epileptic and flashing lights triggers their seizers. Nice build by the way.

Yes, you're right, thank you for sharing!

[@mpalaskokkalis1476]

Perfect 👌

[@bagmus256]

Note 18v Bosch batteries do not have undervoltage protection build in the battery, undervoltage is handel by the tool, building this light and running the battery to low will with 100% certainty permanently dammage the battery, even only once will leave its mark.

Soon I will have to work in the basement of a multi-storey building. And I would really need a good, long-working flashlight. And you have a great job again. Can you try to make a headlamp with your own hands next time? It would be interesting to see this. P.S: I hope that the translator will not spoil the text. 😅

[@mraksnajper8683]

у него на всех самоделках одна проблемма- нет защиты от глубокого разряда ( он убивает литиевые аккумы) у бош, макита, девалт,- защита стоит не в аккуме, а в инструменте, здесь же ее вообще нет нигде. Короче когда поймешь что аккум сел и фонарь светит тускло -будет уже поздновато.

[@mraksnajper8683]

@@user-rx4lx5kq5t прочитайте внимательно всю ветку комментов- вы подтвердили то , что было написано ранее- защита от разряда реализована в самом инструменте , в аккумуляторах ее нет, потому родной инструмент не работает от дохлых аккумов, а самоделки высаживают в ноль.
