Re: Battery building best practices? 18650 packs

Just go for it and learn as you go, get some dead cells from some where (old laptops or power tools) and practice on them, my two cents is this get a really hot soldering iron 300w one from eBay or aliexpress and use that don’t spotweld unless you have a really good one, spotwelding is a good idea b...

Re: Lipos a good option for high performance small pack?

Some forums claim the Lico chemistry allows 12% increase in power and claim max charge of 4.35v, my seller told me that 4.2v is the max for the type of cell I purchased from him, and about not using the max out of the cell, I don’t know about that dude, there is another guy doing what I did only on ...

Re: Assembled Hi-Power LiPo battery packs - any interest?

These things are works of art dude good job, my only thing is why the hell would you do all that work only to run lipos with a 5c rating when there are single cells out there with 50c rating?

Re: Assembled Hi-Power LiPo battery packs - any interest?

Am I to surmise that storing lipos at anything below 4.2 is fine? how goes the cycle tests so far? I've also read and tested (not at any great lengths yet) that if you compress lipos they work better as the partials are forced closer to each other

The green compound the copper is in cased in looks like it, would no doubt, be detrimental to the over all cooling process, claims of 6k continuous, has anyone got one of these can report findings?

has anyone done a system where you shoot water at your hub with a water pump, water on the hub is very effective at cooling the motor, I find that the hub motor with fins and ff work well with no Re Gen but as soon as that Re Gen kicks in the hub becomes a grill pan, although it does stop the motor ...
