Vestwoods 12V lithium batteries for the small DC and single-load jobs around a Texas property — gates, cameras, fences, RVs, boats, cabins, and remote points. Same Vestwoods quality as our 48V line, in a drop-in 12V block that replaces lead-acid with lighter, longer-cycle LiFePO4.
Both share a 100A continuous BMS (about 1,280W). The 200Ah simply runs that load twice as long — it is not more continuous power.
VC12100 · 1.28 kWh · ~25 lb. The one-person, drop-in block for single point loads.
VC12200 · 2.56 kWh · ~51 lb. Double the runtime for longer jobs.
Need more than ~1,280W continuous? Parallel two batteries for 200A, or step up to a 48V system. We confirm the inverter, wiring, and battery count against your actual loads before quoting.
From Vestwoods VC12100 / VC12200 published specs and product category information. We confirm the exact SKU, BMS rating, and certificate paperwork per order.
Same power ceiling — the choice is runtime and weight.
Under ~700Wh a day → 100Ah is plenty. 1,500–2,000Wh a day → start with 200Ah.
On a 100W load, 100Ah runs ~11 hours and 200Ah ~23 hours. Double the kWh, double the hours.
100Ah is a 25 lb one-person lift. 200Ah is about 51 lb — or run two 100Ah in parallel when you want smaller, modular placement.
The small DC and single-load jobs that do not need a 48V system.
Solar gate openers, cameras and CCTV, electric fence energizers, automatic feeders and waterers, and Starlink or Wi-Fi at outbuildings.
RV and camper house batteries, trolling motors, vans, and food trucks — plus a one-for-one drop-in upgrade for any old lead-acid 12V bank.
Internet, router and modem, security and alarm panels, gate-and-camera, and overnight CPAP — the small loads that must ride through an outage.
DIY solar for sheds, cabins, and hunting leases (100–400W panel), plus portable and job-site power. Step up to 200Ah for multi-day cabin use.
The same 12V block is the building block behind solar-powered trailers — and we supply them by the pallet.
PTZ and LPR cameras, cellular, and warning lights sized for multi-day runtime with solar recharge — several 12V blocks per unit.
Solar message-sign, arrow-board, and radar speed-sign trailers for work zones, road warnings, and traffic control.
Remote site monitoring, lighting, and telemetry where running mains power makes no sense.
Cameras, LED signs, routers, and controllers all run 12V DC and recharge from solar. Wire 100Ah or 200Ah blocks into the bank each trailer needs.
Try one before you commit a fleet.
Volume orders shipped from the factory to your yard.
Landed price includes freight, the current U.S. Section 301 tariff, and customs clearance, confirmed in the quote. Factory warranty applies, with local advance-replacement support from Texas stock. Minimum order and lead time are confirmed per project.
Same honest sizing rule as the rest of our lineup.
M8 terminals, ABS case, IP65. Swap an old 12V bank for LiFePO4 with longer cycle life and much lower weight.
App state-of-charge monitoring and a built-in BMS protecting against over-charge, over-discharge, over-current, and over-temperature.
One 12V battery handles up to ~1,280W. For central AC, well pumps, or whole-property backup, use our 48V ranch systems.
LiFePO4 stops charging below 32°F (0°C). The low-temp cutoff protects the cells, so plan a sheltered spot for outdoor Texas installs.
BMS rating, terminals, and UN38.3 / product certificates are confirmed against the shipped unit before the quote is final.
Parallel batteries for more runtime and up to 200A, or move to 48V when the loads outgrow a single 12V block.
Most 12V LiFePO4 problems are setup, not the battery. Here is what trips people up — and what we set right before you buy.
Set the charger to 14.4–14.6V. A lead-acid 13.6V profile never fills the battery — the No.1 “it won’t reach 100%” cause.
LFP pulls hard and can overheat a vehicle alternator. Put a DC-DC charger between the alternator and the battery.
The BMS blocks cold charging to protect the cells. Use a self-heating model or a sheltered, warmer spot.
One battery handles ~100A (~1,280W) continuous. A bigger inverter’s inrush trips the protection — parallel batteries for more.
LiFePO4 voltage is nearly flat, so a voltmeter cannot tell you the level. Use the Bluetooth app for a true percentage.
12V means high current. Undersized cable overheats and drops voltage — add a correctly-sized fuse at the battery. We spec both per load.
The right battery is half the job. We spec and source the parts that prevent the mistakes above.
Charge from a vehicle without cooking the alternator.
Shore or solar charging at the correct 14.4–14.6V.
Correctly-sized protection and battery cables.
For freezing climates and outdoor trailers.
