SOLLVIE 36V 7.8Ah Lithium Battery Pack with Built-in 30A BMS — XT60/SM, 280.8Wh, Compact IP54

The SOLLVIE 36V 7.8Ah lithium battery pack is a compact, protected power module that delivers up to 30A continuous output for Jetson Bolt Pro scooters and medium-power DIY electric projects.

This battery combines a 36V nominal voltage with 7.8Ah capacity (about 280.8Wh) inside a flame-retardant ABS housing sized 7.48 × 2.75 × 2.75 inches. It includes a built-in 30A battery management system (BMS), XT60 discharge and SM charge connectors, and a 42V 2A charger for convenient replenishing. Designed for portability and safety, the pack supports effortless installation and offers IP54 splash resistance and industry certifications.

How much continuous power and peak current can this battery supply?

This battery is tuned for medium-power applications: it provides up to 30A continuous discharge suitable for motors between roughly 100W and 750W. The BMS supports higher short bursts to handle startup currents, with instantaneous current tolerance specified for heavy loads.

• Rated continuous discharge: ≤30A — steady performance for most personal electric vehicles.
• Instantaneous/peak current capability: up to 75A for short bursts (managed by the BMS).
• Nominal energy: ~280.8Wh (36V × 7.8Ah) for realistic run-time estimates.

What protections does the built-in 30A BMS provide?

The integrated BMS actively guards the pack against common electrical faults and helps extend usable life. It controls charging and discharging thresholds and reacts quickly to abnormal conditions to protect both battery and connected electronics.

• Overcharge cutoff at 42.0V ±0.1V to prevent cell stress.
• Over-discharge cutoff at 28.0V ±0.1V to avoid deep discharge damage.
• Overcurrent and short-circuit response (trigger at ≥30A, sub-10ms short protection).
• Temperature safety logic to stop operations outside safe ranges.

How and how fast do I charge this battery, and what connectors are included?

The pack ships with a dedicated 42V 2A charger rated for worldwide AC input, giving a full charge from empty in roughly 4–5 hours at room temperature. Connect using the included SM charging connector and use the XT60 for discharge to controllers or motors — both connectors are common on DIY and aftermarket systems.

• Charger: AC100–240V input, 42V DC output at 2A, global compatibility.
• Typical charge time: ~4–5 hours (0→100% at 25°C).
• Included connectors: XT60 (discharge) and SM (charging) for plug-and-play setups.
• Recommended charging sequence: attach charger to battery first, then plug into mains to reduce sparking risk.

What physical and environmental limits should I plan for?

The SOLLVIE pack is compact and lightweight for its capacity, built with flame-retardant ABS and rated IP54 for splash resistance — it isn’t waterproof and should not be submerged. Observe recommended temperature windows for charging, discharging, and storage to preserve performance and longevity.

• Dimensions: 7.48 × 2.75 × 2.75 inches; weight ~2.0 kg for easy mounting.
• Operating temps: charge 0–45°C, discharge −10–60°C; storage −20–50°C (best 10–30°C).
• IP54 splash resistance — suitable for light wet conditions, not immersion.
• Certifications: CE and RoHS for compliance with common safety and environmental standards.

Who is this for: The SOLLVIE 36V 7.8Ah pack fits riders and makers who need a reliable, mid-capacity battery for Jetson Bolt Pro scooters or 100–750W DIY electrification projects. It’s aimed at users who want straightforward installation, built-in safety management, and a charger included so the system is ready to use out of the box. If you require higher capacity or a different voltage, choose accordingly (36V for 36V systems, 48V for 48V systems).
