The Battery Experts

Totex has been in business for 30 years designing and manufacturing batteries and chargers utilizing Li Ion, NiMH and other chemistries. Experience, vertical integration and lean operations afford them the ability to provide complex high quality batteries and chargers at competitive prices.  Experience with many industries make them a wealth of information to customers who are new to batteries and those with their own expertise.

Military Applications

From a technical standpoint there is no difference between a lithium ion battery used in applications such as

surveying and one used in a military application. The difference is in the testing regime and the documentation.

Typical batteries for non-military applications may undergo testing such as UL2054, IEC62133, or IEEE1725, etc.,

while military batteries undergo MIL-STD 810G. Totex is experienced in testing to MIL standards as well as dealing

with FAR and DFAR clauses. Totex is also ITAR registered.

Totex Custom Chargers

Totex has been making custom battery chargers for over 20 years. As they have their own injection molding capability, if its manufacturable, Totex can make whatever design you want. Options include:

Multiple bays, current designs up to 48 bays

  • Multi-Chemistry
  • SMBus compatible
  • Calibration and built-in test functionality
  • Internal or external power supply/adapter
  • Battery recognition methods

Totex’s MultiBAY Chargers

10 bay battery charger - Multiple bay chargersWhen you need to charge more than one battery at a time, turn to Totex for custom multibay, parallel gang chargers.

  • Up to 10 Charge Bays
  • Multi-Chemistry
  • Up to 50W Fast Charging per Bay
  • SM Bus V1.1 Compatible
  • Single Wire and Other Communication Protocols Available

Semi-Custom Chargers

Totex also has a semi-custom line of chargers with one to six bays. Most of the tooling is already in place and the electronics are already designed to pass all compliance testing.  This minimizes NRE and tooling costs.   Even semi-custom chargers are customizable to some extent.

Custom BatteryPacks

Most of the batteries Totex builds are custom designs, meaning the customer owns the tooling and the design. Although they do have a few common “off-the-shelf” designs. Totex has been designing and building rechargeable battery packs since before Li Ion was the dominant chemistry and has a wealth of experience in many industries and applications:

  • 110mWh to 1500Wh
  • 1.2V to 48V
  • Up to 80A discharge
  • Extreme temperature, ruggedized, water proof
  • Passive and active cell balancing
  • Counterfeit protection
  • Shrink-wrapped, plastic, metal enclosures
  • SMBus, I2C, Single Wire, custom
