Gelion have kept their field data close to their chests and the battery design has changed/improved over 3 generations. As theyre not yet trying to ramp up sales yet that’s likely a wise decision.

The stackable button batteries from 2019 were Gen1, the larger Endure batteries used in the pumps and decal plant etc that you mention above were Gen 2. They had planned to commercialise something similar, but with high capital costs and high factory utilisation required to be competitive with li-ion they pivoted the strategy to design a Gen 3 battery that could be made on existing PbA lines, essentially as just another model on the same line. This should both reduce CAPEX and enable cost competitiveness with Li-ion at modest volumes (as the factories in Aust/India will keep their utilisation up by still making PbA initially). This battery (the monoblock) is still in development/testing. They’ve indicated RTE >87% and “5,000 - 6,000” cycles, but no public info to back that up (presumably the MoU customers have seen data within NDAs).
