Frequently Asked Questions
Himax Battery, as a professional wholesale battery manufacturer, offers a wide range of lithium ion batteries, lithium iron phosphate batteries, nickel metal hydride batteries, and Lipo batteries to meet your different needs with the best ex-factory price and thoughtful customized service.
1. What is a LiPo (Lithium-Polymer) battery and how does it work?
LiPo batteries are rechargeable cells with a polymer electrolyte, offering high energy density and a nominal voltage of 3.7 V per cell (fully charged at 4.2 V and minimum safe at 3.0 V). They’re often built in series (S) and parallel (P) configurations—e.g. a “2S2P” pack uses two cells in series for higher voltage, each duplicated in parallel for greater capacity.
2. How do I safely charge a LiPo battery?
Temperature & Rate – Always charge within 0 °C to 50 °C and never exceed a 1C charge rate (i.e. 1× the pack’s capacity in amps). If you’re unsure of the safe rate, default to 1C to minimize fire risk.
Supervision & Environment – Never leave a LiPo unattended while charging; use a LiPo-safe bag or fire-resistant enclosure, and avoid charging inside vehicles or near flammable materials.
3. What’s the best way to store LiPo batteries long-term?
Storage Voltage – Keep at 40–60 % state of charge (roughly 3.8–3.9 V per cell). Storing fully charged or fully depleted cells for weeks can degrade capacity and reduce lifespan.
Safety Precautions – Place packs in fire-resistant containers or LiPo bags, and store in a cool, dry area away from direct sunlight or combustible materials.
4. How can I prolong the cycle life of my LiPo batteries?
Usage & Replacement – Expect a gradual performance drop of about 3.8 % over the first 100 cycles, and plan to replace packs after 200–300 full cycles or sooner if you see swelling or capacity loss. OEM Quality Matters – Choosing high-precision, matched-cell packs with robust protection boards and thermistors from reputable factories—like Himax with its advanced BMS balancing and tight cell tolerances—can significantly extend overall battery life.
5. Where can I purchase reliable, customizable LiPo battery packs?
For volume pricing, fast lead-times and full OEM flexibility—voltage, capacity, C-rates, connector types, wire-outs and labeling—factory-direct suppliers such as Himax are top choices. Himax’s LiPo division supports low-MOQ wholesale orders and custom engineering to fit aerospace, drone, wearable or IoT applications.
