EnergySystem
Scrap Tech Workshop uses batteries to power devices. Think of it like your phone or laptop battery!
- Energy Cell: Small battery for tools (like a phone battery)
- Energy Cell Block: Medium battery for machines (like a laptop battery)
- Power Cell Bank: Large battery for industrial equipment (like a car battery)
Perfect for portable tools like the Scrap Multitool.
- Capacity: 5000 mAh
- Voltage: 3.2V (LiFePO4 chemistry)
- Power: 16 Wh (enough for ~100 tool uses)
- Use: Handheld tools, portable devices
💡 Think of it as: A smartphone battery
Chemistry: Uses LiFePO4 (Lithium Iron Phosphate) - safer and more durable than standard Li-Ion
Used in small machines like the Collector Station and Recycler.
- Made from: 4 Energy Cells + 4 Copper Wire + Redstone (BMS)
- Capacity: 10000 mAh (double a single cell!)
- Voltage: 12.8V nominal (12V system)
- Power: 128 Wh (enough for ~200 machine operations)
- Use: Stationary machines, workshops
💡 Think of it as: A car battery or power tool battery pack
Why 12V? This is the universal voltage standard used in cars, RVs, boats, and solar systems worldwide!
Fun Lore: Scavenged from pre-war electric vehicles, these battery blocks were originally designed for reliable 12V power delivery. Workshop tinkerers discovered that combining 4 cells with salvaged copper wiring and a basic BMS creates the perfect power source. The remaining 2 cells? Their copper internals become the connection wires - nothing goes to waste in the scrap workshop!
For heavy-duty industrial machines.
- Made from: 4 Energy Cell Blocks in series
- Capacity: 10000 mAh
- Voltage: 51.2V (48V nominal system)
- Power: 512 Wh (enough for ~800 operations)
- Use: Large factories, solar storage, continuous operation
💡 Think of it as: An electric vehicle battery or telecom backup system
Why 48V? Industry standard for e-bikes, golf carts, solar installations, and telecommunications!
Fun Lore: When the scrap workshop veterans needed more power, they simply stacked four battery blocks in series. The result? A robust 48V system that could run entire production lines. Old-world engineers would be proud of this elegant solution born from necessity.
- Craft or find an Energy Cell
- Place it in your device's battery slot
- Watch the energy bar fill up automatically
- Replace when empty (you'll get an empty cell back)
Energy Cell → Device's Internal Storage → Powers Operations
Your device stores some energy internally (like a buffer), so it keeps working even if you remove the battery for a moment.
mAh = milliampere-hours
- Higher number = Battery lasts longer
- 5000 mAh = can provide 5000 mA for 1 hour
- Or 500 mA for 10 hours
- Or 50 mA for 100 hours
Simple rule: Bigger number = more battery life!
Wh = Watt-hours (total energy stored)
- Energy Cell: 16 Wh = small (3.2V × 5000 mAh)
- Energy Cell Block: 128 Wh = medium (12.8V × 10000 mAh)
- Power Cell Bank: 512 Wh = large (51.2V × 10000 mAh)
Simple rule: Higher Wh = device runs longer before needing a battery swap!
| Device | Battery Type | How Long It Lasts |
|---|---|---|
| Scrap Multitool | Energy Cell | ~100 uses |
| Collector Station | Energy Cell Block | ~200 cycles |
| Recycler | Energy Cell Block | ~100 operations |
| Industrial Machines | Power Cell Bank | ~800 operations |
Found in loot or crafted from scrap materials (recipe varies by world).

Combine 4 Energy Cells + 4 Copper Wire + Redstone (BMS)
Configuration: 3S2P (3 cells in series × 2 in parallel)
- 3 cells in series: 3 × 3.2V = 9.6V → BMS boosts to 12.8V
- 2 strings in parallel: 2 × 5000 mAh = 10000 mAh
- Result: 4 cells used + 2 for wiring = 12.8V @ 10000 mAh
Workshop Story: The BMS (Battery Management System) is just salvaged redstone circuitry! Early scrappers discovered that redstone could regulate voltage and prevent overcharging. Two cells are sacrificed for their internal wiring to connect everything properly - crude but effective workshop engineering!

Combine 4 Energy Cell Blocks + Advanced Wiring
- ✅ Always carry spare batteries - swap them quickly!
- ✅ Upgrade to blocks - they last longer than single cells
- ✅ Recharge stations - coming soon for automatic recharging
- ✅ Check the energy bar - green = full, red = almost empty
- 🔋 Bigger battery ≠ slower - all batteries charge at the same speed
- 🔋 Internal storage helps - your device keeps working while you swap batteries
- 🔋 Empty cells are reusable - just recharge them (feature coming soon!)
The Scrap Tech energy system can work with other popular tech mods:
- Forge Energy (FE/RF): Compatible via converters
- IndustrialCraft² (EU): Use IC2 adapters
- Mekanism (Joules): Universal cables work
- Immersive Engineering: Direct 12V/48V connection
If you're using other mods, here's how our batteries compare:
| Our Battery | Forge Energy (FE) | IndustrialCraft² (EU) | Mekanism (J) |
|---|---|---|---|
| Energy Cell | 16,000 FE | 4,000 EU | 40,000 J |
| Cell Block | 128,000 FE | 32,000 EU | 320,000 J |
| Power Bank | 512,000 FE | 128,000 EU | 1,280,000 J |

- 1S1P: 1 cell (3.2V, 5000 mAh) - LiFePO4 chemistry
- 3S2P: 4 active cells + 2 donor cells - 3 in series × 2 in parallel (9.6V → 12.8V with BMS boost, 10000 mAh)
- 4S: 4 blocks in series (51.2V, 10000 mAh)
The Energy Cell runs at 3.2V using LiFePO4 (Lithium Iron Phosphate) chemistry. The Energy Cell Block operates at 12.8V, which is the 12V automotive standard. Finally, the Power Cell Bank delivers 51.2V, matching the 48V industrial standard.
LiFePO4 (Lithium Iron Phosphate) offers significant advantages over standard Li-Ion. It's much safer with a lower fire risk, making it ideal for workshop environments. The chemistry provides 2000+ charge cycles compared to just 500-800 for Li-Ion, and performs better in extreme temperatures. The 3.2V per cell voltage makes clean 12V/24V/48V systems easy to build. The only trade-off is slightly lower energy density, but we compensate by using more cells.
Energy Cells charge at 25 mAh/tick (500 mA/s, 1.6W) and discharge at 100 mAh/tick (2A/s, 6.4W). Energy Cell Blocks charge at 50 mAh/tick (1A/s, 12.8W) and discharge at 200 mAh/tick (4A/s, 51.2W), which is twice as fast as a single cell thanks to the parallel configuration. Power Cell Banks discharge at 200 mAh/tick (4A/s, 204.8W) for heavy industrial use.
Power (W) = (mA × V) / 1000
Energy (Wh) = (mAh × V) / 1000
FE = Wh × 1000
EU = FE / 4
J = FE × 2.5
Conversion Chain:
- mAh × Voltage = Wh (actual energy)
- Wh × 1000 = FE (Forge Energy)
- FE × 2.5 = J (Mekanism Joules)
- FE / 4 = EU (IndustrialCraft²)
3.2V Energy Cells are used in modern power tools, e-bike cells, and solar storage batteries. * 12V Cell Blocks* match car batteries, RV systems, boat electronics, and solar setups. 48V Power Banks are the standard for e-bikes, golf carts, telecom backup systems, and industrial solar installations. All three voltage levels are international standards recognized worldwide!
3S2P (Energy Cell Block):
The configuration uses 3 cells in series (3 × 3.2V = 9.6V) with a built-in BMS boost converter ( redstone magic!) that steps up the voltage from 9.6V to 12.8V (nominal 12V). Two strings run in parallel, giving us 2 × 5000 mAh = 10000 mAh capacity. The result is 4 active cells plus 2 donor cells (for wiring) achieving the standard 12V voltage and doubled capacity. This is exactly how car batteries and RV systems work! The boost converter lets us hit the industry-standard 12V with fewer cells, showing typical scrap workshop ingenuity. Transfer rates are twice as fast as a single cell due to the parallel configuration, doubling the current capacity.
4S (Power Cell Bank):
Four blocks connect in series (4 × 12.8V = 51.2V) to create the nominal 48V high voltage system. The capacity stays at 10000 mAh, but the 4× higher voltage means 4× more power delivery. This gives us industrial-grade power for heavy machinery, matching the standard used in e-bikes, telecom towers, and solar installations!
Workshop Wisdom: Old-world engineers used complex electronics for voltage regulation. Scrap workshop tinkerers? They use redstone, copper wire, and clever cell arrangements. Different methods, same reliable results.
