πŸ”‹ Battery Types Comparison

Battery Type Energy Density Charge Cycles Weight Advantages Disadvantages
Li-ion (Lithium-ion) High 500–1000 Light Widely used, fast charging Heat sensitive, relatively expensive
LiFePO4 (Lithium Iron Phosphate) Medium 2000–5000 Heavier Very safe, long lifespan Lower energy density
NMC (Nickel Manganese Cobalt) Very High 1000–2000 Light Efficient, popular in EVs Expensive, less stable at high temps
Lead-Acid Low 300–500 Very Heavy Cheap, reliable Short lifespan, slow charging

πŸ”‹ Lithium Battery Cells Comparison

Popular and generic 18650 / 21700 lithium-ion cells used in e-bikes and DIY battery packs.

Brand / Model Capacity (mAh) Max Continuous Discharge (A) Cycle Life (approx.) Price Range Notes
Sony VTC6 (Murata) 3000 15–20 500–800 High Balanced between capacity & power, very popular
Samsung 30Q 3000 15 500–800 Medium Common in e-bikes, good all-rounder
Samsung 40T (21700) 4000 30–35 600–1000 High High power, good for high-drain builds
LG MJ1 3500 10 500–800 Medium High capacity, moderate current
Panasonic NCR18650B 3400 6.5 500–800 Medium Very high capacity, low discharge
Molicel P42A (21700) 4200 30–45 800–1000 High Top choice for performance builds
Generic Chinese 18650 2200–2600 5–10 200–400 Low Cheap, inconsistent quality, not recommended for large packs
No-name β€œUltrafire” Claimed 5000+ (real ~1000–1500) 2–5 <200 Very Low Often counterfeit, unsafe for e-bikes
