We’ve extended the techno­logy front with two new flagship next genera­tion lithium-ion cells from V4Smart!
⚡ V21700 HP-5X
– 299 Wh/kg energy density
– 2.63 kW/kg power density
⚡ V21700 (U)UHP-3X
– 192 Wh/kg energy density
– 5.56 kW/kg power density
You can also check out the key features of the cells via the V4Smart website or contact us directly via info@batemo.de.

The Tenpower 50XG is another serious power­house nestled amongst the tabless cells in the Batemo Cell Explorer 💥

🔌Energy Density (volumetric): 734 Wh/l
💡Power Density (volumetric): 6.95 kW/l
🔋Capacity (C/10): 5.12 Ah
⚡Current range: -30C to 4C

The 50XG shows strong high-power capabi­lity, and like all high-perfor­mance cells, the sustainable opera­ting window is set by heat manage­ment. Short bursts? No problem. Conti­nuous high power? That’s where thermal design makes or breaks the system.

We’ve expanded the Ampace JP family with 2 high perfor­mance cells!

🆕 JP50: ~260 Wh/kg | 5 Ah (optimised for energy)
🔋 JP40: ~227 Wh/kg | 2.36 kW/kg | 4 Ah (balanced)
🆕 JP30: ~2.8 kW/kg | 3 Ah (optimised for power)

New Reliance Energy Cells in the Batemo Cell Explorer!
We’ve added two high-perfor­mance tabless 21700 cells from Reliance Energy — the RS40 and RS50.
⚡ RS40: 4.0 Ah | 227 Wh/kg | 2.38 kW/kg
⚡ RS50: 5.0 Ah | 274 Wh/kg | 2.55 kW/kg (new power density record!)

New Chemistry Pairing in the Batemo Cell Explorer!
We’ve added a unique LFP | HC (Lithium Iron Phosphate + Hard Carbon) cell to the Batemo Cell Explorer — combi­ning safety, durabi­lity, and high power.
Tested: BePowered-310 from @BeyonderAS (33 Ah, 1.35 kW/kg, 116 Wh/kg).
This pairing enables high-power, stable, and sustainable cell perfor­mance.

In power tool applications, battery cells must deliver high discharge currents, maintain thermal stabi­lity, and provide reliable runtime under deman­ding opera­ting conditions. Selec­ting the right cell is crucial to meeting these perfor­mance requi­re­ments.
Cells like the Molicel P50B, Highstar 50PS(B), BAK 45D(B), Tempower 40XG, and Ampace JP30-PI(C), reflect the innova­tion happe­ning in this space.
We highlight some of the nuances in our full post on LinkedIn, using insights from the Batemo Cell Explorer.

The Amprius SA03, featuring its cutting-edge patented SiCore™ anode, measured in with an energy density of 399 Wh/kg, matching almost exactly the 400 Wh/kg reported by the manufac­turer.
The SA03 now holds the record for highest energy density across all cells in the Batemo Cell Explorer!
The SiCore™ cells from Amprius that leverage a multi-layered silicon anode archi­tec­ture designed to overcome one of the biggest challenges in silicon-based cells: expan­sion stress.

Until now, we have developed over 130 physical Li-ion cell models with an array of chemis­tries ranging from NMC, NCA, and LFP cathodes to graphite, silicon, and LTO anodes.
We’re thrilled to announce that we have now released our first physical sodium-ion (Na-ion) cell model into the Batemo Cell Model Library! 

At the forefront of Na-ion techno­logy, the Farasis S35(B) pouch cell delivers an impres­sive energy density of 150 Wh/kg, nominal capacity of 34.3 Ah, and a power density of 807 W/kg making it one of the most advanced repre­sen­ta­tions of Na-ion cells under development for commer­cial use at the moment.
