Basically, when a robot needs to work a full shift without quitting halfway, that's where this battery pack comes in—customers of yours running automated floor cleaners or AGVs usually find the 4000mAh capacty gives them about 4-6 hours of run time depending on the draw.
We've built in BMS protection that catches overcharge at 7.3V and overdischarge at 4.0V, so it's pretty much idiot-proof for most setups, and the 0V battery charge function means you don't have to worry if someone drains it dead flat.
You'll get CE, FCC, ROHS, UN38.3, and MSDS certs with every order (we keep those on file), but what most buyers don't think to ask is that the NTC resistor is customizable—if your robot's BMS expects a specific thermistor curve, our company can match it.
It's not great for high-drain applicaion like power tools since teh max continuous discharge is capped at 2A, but for sensor platforms or slow-moving bots that's actually better than most generic packs because the low discharge rate keeps the cells stable.
Anyway, for ordering we need your target charge/discharge currents and preferred OEM branding on the label—lead time is roughly 25-30 days for the first batch, and we usually have stock for samples within a week or so.
Actually, one thing that catches people off guard is weight—at about 190g it's heavier than a phone battery, but for a 6.4V pack that's pretty standerd given the 26650 cells inside.
MOQ depends on the specific model and customization. For standard YLY26650 packs, we typically start at 500 units, but for OEM/ODM orders we can discuss smaller trial runs.
Lead time is usually 3-4 weeks after sample approval and deposit, depending on the complexity of your customization like NTC resistor or operating temperature specs.
Yes, all certificates including CE, FCC, ROHS, UN38.3, and MSDS are included with each shipment. We can also share copies before shipping for your verification.
Nominal capacity is the typical value at 0.2C discharge, while minimum capacity is the guaranteed lowest you'll get from any unit. So you're always getting at least 3950mAh.
We pack them in standard safe export cartons with proper cushioning and UN38.3-compliant labeling for lithium batteries. Each carton is sealed and labeled with product details.
