Common Applications We Support:
Deka LFP Smart Batteries Now Available in Our MAPPS Remote Solar & UPS Power Systems!
Built for the Jobs Lead-Acid Can't Handle
Four industries where Deka Duration 12V Smart LFP replaces 8D and Group 27 GEL/AGM banks. 6,000 cycles, 60% lighter, one install in place of 5 to 10 lead-acid truck rolls.
Security Camera & Surveillance Systems
Solar security cameras, PTZ enclosures, and LPR trailers built on 12V Group 27 AGM or Gel banks fail on a 2 to 3 year cycle, and every replacement pulls a tech off higher-value work. The Deka Duration DD100-12 is a Group 27 LFP drop-in with IP67 protection and a single-person 26 lb form factor. Heated DD100-12H LFP batteries charge to -4°F for perimeter and utility sites in cold climates.

Oil & Gas Lithium Batteries for Wellheads, SCADA & RTU
Wellheads, SCADA cabinets, RTU enclosures, and cathodic protection rectifiers sit hours from the nearest service road. Deka Duration drop-in lithium batteries replace 8D and Group 27 GEL/AGM banks with fire-rated ABS+PC cases, IP67 protection, and heated LFP batteries for cold-climates. Parallel up to 16 units for loads, with CAN-Bus state-of-charge data feeding back to SCADA.
- IP67 Fire-Rated
- 16 Parallel
- -4° to 140°F
Portable Traffic & Arrow Board Trailers
Arrow boards, message boards, radar trailers, and solar light towers typically run four 70 lb Group 27 lead acid batteries per unit. When the bank fails every 2 to 3 years, swap day means a tech lifting 280 lb of lead-acid out of the trailer and 280 lb back in, the kind of repeated heavy lift that drives OSHA citations and workers' comp claims. The DD100-12 drops in at 26 lb per battery with 99% round-trip efficiency and 5x the service life, so swaps happen a fraction as often and are easy to manage.

- 5× Service Life
- 99% Efficiency
Industrial Solar & Off-Grid Power
Remote solar arrays, DC UPS cabinets, transmission tower obstruction lighting, and MAPPS pole-mount systems run on 8D, 4D, and Group 27 GEL/AGM banks that need full bank replacement every few years. Deka Duration DD100, DD300, and DD460 LFP monoblocs wire into 12V, 24V, 36V, or 48V strings with CAN-Bus comms, passive balancing, and 100% usable depth of discharge. One lithium install where a lead-acid bank would have cycled through 5 to 10 replacements.
