"Mini Monster" 72V 120A 8Ah in a tiny package
The XT60 is attached to a 50A BMS and doubles as a charging port. The XT90 will give you the full 120A (160A burst). Very powerful battery! Made with Tenergy cells.
Puts out 8,640W nominal. 13,440W MAX!
$300

Re: "Mini Monster" 72V 120A 8Ah in a tiny package
So the XT90 bypasses the BMS for over-current protection? If so should a fuse be fitted?
I assume the BMS OVC and LVC still works, what via a contactor?

Re:
Fusing it at 100A may be a good idea in case of accidental shorts resulting from cut cables and whatnot. XT90 equipped inline fuses are easy enough to make, and I can build it if need be. The BMS and all of its protection/balance circuitry are active on the 50A (XT60) leads. The XT90 is the "lipo mode" and will work exactly like a large, high-powered RC lipo setup.

In other words direct pass-through to the bare cells, rely on external controls to protect at the pack level against over- or under- voltage conditions?SwampDonkey wrote:The XT90 is the "lipo mode" and will work exactly like a large, high-powered RC lipo setup.
If so, cool, nice to have a choice.
Could you build a version maybe without internal BMS, but exposing the cell/group leads?
Can you share the specific cells used?

Re: Re:
Yeah, sure. I can build whatever you like. And its these cells here: https://rechargeablebatterystore.com/11 ... tery-pack/john61ct wrote: ↑Aug 23 2019 7:38pmIn other words direct pass-through to the bare cells, rely on external controls to protect at the pack level against over- or under- voltage conditions?SwampDonkey wrote:The XT90 is the "lipo mode" and will work exactly like a large, high-powered RC lipo setup.

Confused. That is a pack, not single cells. I assume pouch type?
In your OP pics there are the purple cylindricals showing, are you saying the packs you're selling are not made from those?
Could you link to the actual cells?

Re:
Right, thats another battery made with different cells (NCR18650BD). I havent seen the cells Im using being sold individually. These were ordered from an industrial supplier by a University. You can see them here: https://rechargeablebatterystore.com/li ... 6-battery/

Do you make these? Can you make with a higher ah?
