2nd Generation High Current Rechargeable Lithium Batteries
Due to limited resources we cannot accept new customers for these cells, sorry. (Except for 12V 55AH packs, click here)
|Second generation lithium-ion Large Lithium-ion cells and Batteries are now available with higher currents, and longer life.|
Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for OEMs in a hurry!
These li-ion cells and batteries not only have high capacity, but can deliver high power. One 12 AH cell can supply 130 watts, a 4 cell pack can supply over 500 watts at 12 volts. High-power lithium ion batteries are now a reality. They can be used as storage cells or power sources.
All of the following products are available. Chargers and battery management boards are available. We are now offering total turn-key solutions for almost any capacity and voltage made of the following building blocks. Delivery is typically 8 weeks. For faster deliveries see the large format lithium polymer power cells.
12 Amp Hour Cells
60 Amp Hour Cells
Chargers are available to recharge battery packs from 12 Amp Hours to 400 Amp Hours, 3.6 volts to 400 Volts. They are constant current--constant voltage, terminate at 100 mA algorithm.
** Chargers for any number of cells are readily available with 3-5 week lead time.
Battery management boards
The battery management board is essential to maintain a safe, long lived battery pack. They have the following functions.
1. Balance charging current among the cells in the pack to insure all cells are fully and evenly charged.
2. Protect the cells in the pack from overcharge.
3. Protect cells from overcurrent.
4. Protect the pack from short circuits.
5. Protect the cells in the pack from overdischarge.

Packs can be made to your specification, both in series, or series-parallel. For example a 4S2P (4 series 2 parallel) pack can make a 14.4 volt, 24 AH pack out of 8 3.6 volt, 12 AH cells.
State of the art lithium-ion cell with laser welded stainless steel cases, no polymer, rubber, or plastic seals.
Cells under development or available from 3AH to 60 AH.
High Discharge rates
Priced competitive with other battery chemistries.
