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



Battery rechargers
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.
