Venom Stronghold 25 Amp DC Battery Charger

Venom Stronghold 25 Amp DC Battery Charger

Venom breaks the mold again with their new Stronghold 25amp DC battery charger. The charger can charge packs up to 25amps and the included Stonghold containment system features a self extinguishing, shatterproof, polycarbonate window and with built ambient LED lights so you can keep an eye on your pack. Check out the rest of the highlights in the press release below:

Venom is proud to bring you another game changing solution to your charging needs with the new Stronghold 25 Amp DC Battery Charger; the world’s first charger that combines cutting-edge technology and improved charging safety in one package. This revolutionary charger offers a full 500-watt circuit and allows charge rates up to an astonishing 25amps. The panel features an easy-to-read backlit LCD screen and an easy to use intuitive programming menu.

The Stronghold also allows you to keep track of your LiPO packs performance and condition with the new IR-Mode ™ internal resistance test. IR-Mode™ tests each cell individually and provides single cell and total pack resistance values so you can see the real-time condition of your LiPO and LiFe battery packs.

This robust charging solution features durable stamped aluminum construction which aides in heat dissipation and was designed for years of real life use, unlike cheap plastic chargers. Our Factory Team Pilots asked for this DC charger to allow a wide variety of input voltages up to 26 volts, compatible with today’s high voltage, low current power supplies.

For most companies that would have been enough, but the engineers at Venom took it a step further and combined the feature rich Stronghold Charger with our Stronghold Solo Battery Charging Containment System.

A hobby industry first, the Stronghold Containment System improves the safety of charging and discharging LiPO batteries up to 60-watt hours. The Stonghold containment system features a self extinguishing, shatterproof, polycarbonate window and ambient LED lights inside for easily viewing the battery during charge and discharge sequences. No external charge or balance wires are needed, since all outputs are mounted to a baffle between the charger and the Stronghold Containment System. This results in a cleaner and safer charging setup. Should a catastrophic battery failure occur, specially designed venting will help dissipate smoke and fumes in a controlled manner, while helping to contain flames and debris.

*NOTE: The use of the Venom Stronghold 25 Amp DC Battery Charger does not eliminate the risk of a lithium polymer battery fire. Users should always follow the safety warnings, instructions and guidelines provided by their battery and charger manufacturers in connection with this product.
