Semi solid state battery for foil assist

I am toying with the idea of changing one of my foil assist batteries to semi solid state one. Anyone have experience running VESC with semi solid state batteries? Any reasonable supplier in China that can manufacture/sell these that will have similar form factor to 13s2p liion?

I will keep my battery case, just looking to replace the actual battery pack and reconfigure bms/vesc. Or could consider getting new bms if not supplied with the battery.

It does not need to be 48V, I could go down to 10s equivalent for testing. Just curious if this has been done and if worth pursuing.

I’m pretty sure semi solid state is nothing proven yet. Bea bet to go with high power cells for an assist like RS50/50XG/50PL etc.
A 2P setup will give you enough power for sure.

Thanks. I am aware of high power cells, but keen to explore a safer alternative to liion cells. Too many restrictions and issues with lithium-ion batteries.

In that case the only practical option is lifepo4–if you REALLY want safe, LTO would be the best, but those are extremely heavy for the capacity.

I have ordered 4 of these, a friend of mine has them and prefers these over his li ion 12s2p in his backpack foil assist setup. Will report back when they arrive, plan to use them in my current 12s 2/4p foil assist backpack.

Those do look good! Wonder what they cost. They make huge batteries.

Apparently twice the price of Samsung 50S for 12S2P

Very interesting. Apparently it is real. New technology.
25% less weight, 50% the size.

Specifically these are Racepow - they have a website. Shenzhen Hanhailong on Alibaba sell them.
350-400WH/kg. Can be bought as packs or individual cells. The cells are attractive because can be soldered probably into a pack with BMS.
Price is about twice the 21700 li-ion variants.

Here is a little video about the technology:
