SX350 100W Chip From YiHiecigar

Sorry if this is a dumb question but £64.99 for the chip when you can go to myepack and buy a 100w box mod for £59.99....

I was thinking the same at first until Seedy filled me in on the differences between the sx330 v100 and the sx350 v100. sx350 has dual battery buck boosters so it can boost each battery when they go below 3.7v so it will still get up to 100watts, sx330 can only really achieve 100watts on fully charged batteries.
Updates will be released for the sx350 that will take it up to the 180-200watt range.

In short the SX350 is a real 100watt chip even when the batteries go below 3.7v.

Sx350 has a lot more software features than the Sx330, bypass mode, memory banks etc.

All of the above. Thanks Badaboom. I do agree that they are pricey but they are better than the 330. The taxman is the reason they cost what they do. Damn you taxman! ;-)

Suppose in this case you get what you pay for.

Since Seedy opened his shop he has always sold top quality products at reasonable prices (usually a lot cheaper than other UK vendors). Send yihi an email and complain at the price and maybe they will listen.

Am I missing something, the SX330 100W and the SX350 100W are 7.4V input chips?


While on the subject of 7.4V, has anyone had any ideas for onboard charging 2S battery packs?

I am looking at building my next woody with sx350 100W but 7.4v makes charging a pain.
I have picked up some XT60 panel mounts although they are quite big, glad I didn't get the XT90's. It also means I will need yet another charger for my boxes!

And 3.7v batteries are 4.2v. I don't get why but I know these sx350 can take 2 18650 batteries whether they are 4.2 or 3.7v.
Does anyone know why?

I was told on another forum, YiHi did it so there won't be drastic battery sag when vaping higher wattage.

All cells have a nominal voltage and a charged voltage.

So a nimh aa battery is 1.ŕv charged but 1.2v nominal

Li ion charge to 4.2v but spend most of their operating life at 3.7v and should be considered discharged at 3.2v.

These idiots that charge at 3.7v are simply wasting most of thr life of the cells.




With regards to charging. I'm not aware of a usb board that can boost from 5v to 8.4v AND balance charge your cells. My advice would be to look to the RC world, buy an imax b6 they are cheap and effective balance chargers and the rc plane guys have been balance charhing lipo cells on board for years so have suitable connectors.

Its much easier though to connect up a 2s lipo pack with a deans connector, and secure the door with magnets, when the battery is flat, pull it and drop in a spare just plug the deans connector into a lead on the charger, the balance lead on the battery into thr balance port on the charger and let it do everything for you.

That's certainly how I will be working with my own builds.
