ANCEL BS300——Balanced Performance Battery Guardian BS300 — Permanently Mounted Battery Protection SystemAlways Connected. Always Ready. Never Stranded. Most jump starters live in your trunk.They collect dust — until the day they're dead too. BS300 lives under your hood.Working every start. Every day. Before anything goes wrong. WHY TRADITIONAL JUMP STARTERS FAIL The Tool You're Counting OnMight Not Be There When You Need It. Traditional jump starters were designed for emergencies.BS300 was designed to prevent them. TRADITIONAL JUMP STARTER | BS300 BATTERY GUARDIANStored in trunk | Permanently installed under hoodNeeds recharging | Always connectedSelf-discharges on shelf | 3mA standby — never diesLithium battery aging | 500,000-cycle supercapacitorFails in cold weather | Full output at –40°FDead when needed most | Always readyEmergency rescue tool | Proactive guardian system The difference isn't just the technology.It's the entire philosophy of how a starting system should work. BATTERY GUARDIAN SYSTEM BS300 Doesn't Wait for Your Battery to Fail.It Makes Sure It Doesn't. Every start. Every day. Silent protection — working in the background. 01 | ABSORBS CRANKING LOADEvery ignition, BS300 steps in first — absorbing the full peakcranking current before it reaches your main battery.Your battery never takes the hardest hit. 02 | REDUCES BATTERY STRESSPeak cranking is the single greatest cause of battery degradation.BS300 eliminates that stress — every single start,for the life of the vehicle. 03 | EXTENDS BATTERY LIFE UP TO 3×Less stress per start means measurably longer battery life.Not a marketing claim — a direct result of reduced peak loadon every ignition. 04 | MONITORS BATTERY HEALTHBS300 reads your battery's real-time voltage and health statusat every connection — building a picture of long-term declinebefore it becomes a problem. 05 | PREVENTS UNEXPECTED FAILUREBatteries don't send warnings. BS300 does.Low-voltage alerts. Health trend notifications.You'll know before the morning it won't start. 24/7 APP MONITORING Your Battery Finally Has a Voice. Most starters give you one light. Green means go.That's not intelligence. That's guessing.BS300 gives you the full picture —before, during, and after every start. 01 | REAL-TIME VOLTAGELive battery voltage on your screen — not a 3-bar LED estimate.Know exactly what you're working with before every start.Peace of mind: you know it's ready before you walk to the car. 02 | BATTERY HEALTH MONITORINGTracks long-term voltage trends and health degradation.Your battery's life story — logged automatically, reviewed anytime.Peace of mind: 24/7 guardian for your battery. 03 | ANOMALY ALERTSLow-voltage push notifications to your phone.Fix the problem before you're stranded — not after.Peace of mind: warned before it happens. 04 | START HISTORY LOGEvery ignition logged — date, time, battery condition at start.A complete record that tells you when to replace the battery.Peace of mind: your battery's story, always on record. 05 | FORCE-START MODEWhen standard output isn't enough — activate maximum availablecurrent directly from the app.The last line of defense, when everything else has failed.Peace of mind: there's always one more option. 06 | AI SMART LEARNINGAnalyzes your driving patterns and battery behavior over time.Optimizes startup output for your specific vehicle and usage.Peace of mind: smarter every drive. iOS & Android · BLE 5.3 · No account required · Free download SUPERCAPACITOR VS LITHIUM This Is Why BS300 Costs More.And Why It's Worth Every Dollar. You're not paying for a bigger battery.You're paying to eliminate the battery entirely. LITHIUM JUMP STARTER | BS300 SUPERCAPACITORSwelling risk in heat | No swelling. Ever.Thermal runaway risk | Zero thermal runawayBattery aging — capacity fade | 500,000 cycles — zero degradationFails below freezing | Full output at –40°FHeat sensitive above 140°F | Rated to 176°FNeeds regular recharging | Always connected — always readyEmergency use only | Daily protection system Supercapacitors store energy electrostatically — not chemically.Physics doesn't age. Physics doesn't swell.Physics doesn't take days off. PERMANENT UNDER-HOOD INSTALLATION Built to Live Under Your Hood.Not Visit It. BS300 isn't a tool you grab from the trunk when things go wrong.It's a system that's already working — before things ever go wrong. ALWAYS CONNECTEDWired directly to your vehicle's electrical system.3mA standby draw — less than your car's own ECU at idle.No drain. No maintenance. No thinking about it. IP65 RATEDDustproof. Water-resistant.Built for the engine bay environment — heat, vibration, moisture.Not the glove box. Not the trunk. The engine bay. ZERO LITHIUMEngine bays reach 200°F+ in summer.Lithium cells become unstable above 140°F — a real risk for anypermanently installed lithium device.BS300 has zero lithium inside.Safe to install. Safe to leave. Safe forever. EXTREME ENVIRONMENT –40°F to 176°F.BS300 Doesn't Care. Supercapacitors store energy electrostatically.Temperature has no say in the matter. WINTER COLD START–20°F. SUV parked outside overnight.Battery at 30%. Lithium starter at maybe 60% output.BS300 at 100%. Always. DESERT SUMMERPhoenix. July. Engine bay at 190°F.Lithium cells are stressed above 140°F.BS300's supercapacitors are rated to 176°F.Stable. Safe. Ready. LONG PARKINGTwo weeks in the airport lot.Battery drained to residual voltage.BS300 charges from what's left — 3 to 10 minutes.Engine running before you reach the exit. DAILY COMMUTE6 AM. January. Every morning.BS300 doesn't have bad days.It just starts your car. BS300 is not the biggest in the BS series.It's the right one for most drivers.The SUV in your driveway.
