TP5100 4.2 Volt or 8.4 Volt Lithium Ion Battery Charger

These TP5100 integrated lithium-ion battery charging boards are more capable than the well-known TP4056. They're more efficient and have greater charge capability (2A vs. 1A for the TP4056). They can also be set for 2S (8.4v) charge by shorting the SET pads. We've built a few cell-string balancers from these to top balance individual strings within a battery assembly.

Charging current can be set between 0.1 and 2 amps by adding resistors, and a blue/red LED indicates charging status (red = charge complete, blue = charging or no cell inserted). This is a buck charger so input voltage must be greater than output. We recommend 5v input for 1S and 12v input for 2S charging.

Features

We ship the majority of our orders by the next business day. Lithium batteries may take up to two business days to process to accommodate inspection and logging into our system.

Our shipping rates are based on the weight of all ordered products plus estimated weight of packaging. We make every effort to forecast an accurate shipping cost, but cannot be 100% certain in all cases. Please contact us at sales@higherwireenergy.com with any questions prior to purchase.

We pack and label all lithium battery shipments in accordance with Federal Regulation 49CFR173.185, as well as USPS Publication 52 Hazard Class 9 or UPS/Fedex guidelines. Unless otherwise stated, lithium batteries are not eligible for free shipping.

We try to pack all items in an order in a single box, however we may on occasion need to ship items separately. Special shipping does not apply to lithium ion batteries, and orders that include batteries may not qualify for free or expedited shipping.
