Dakota Lithium 12V 100Ah Deep Cycle Heated LiFePO4 Battery
12V (12.8 V nominal) 100 Ah LiFePO4 battery, 12.5 kg, with 1,280 Wh stated energy, a 100 A continuous discharge, a 200 A 10-second surge, and integrated self-heating that warms the cells before charging below freezing. Group 24 case, 11-year warranty. No cycle-life figure is published with a depth-of-discharge basis, so none is recorded.

A battery is a component, not a power supply. Rated capacity is measured at a stated discharge rate and temperature (shown below where the manufacturer publishes it). Real usable energy is lower and depends on the depth of discharge you run the pack to, the load, the temperature and the inverter it feeds. This index publishes rated figures only and derives no single "real usable watt-hours" number. On its own a bare
battery has no inverter, no charge controller and no AC outlet: it stores energy for a system you
build around it, and its safe charge and discharge limits (in the specifications below) are part of
that system design.

This is Dakota Lithium's 12V 100Ah deep-cycle lithium iron phosphate battery, now sold only in its heated form. It is rated 100 Ah and 1,280 Wh at a 12.8 V nominal, in a Group 24 case weighing 12.5 kg. Discharge is 100 A continuous with a 200 A surge rated for 10 seconds, and charging is capped at 50 A. Its distinguishing feature is Dakota's internal heating element: when the battery is charged below 0 C, the element warms the cells to about 5 C first, which is what lets a LiFePO4 pack accept charge in freezing conditions at all. Dakota backs it with an 11-year warranty, the longest of any battery indexed here. Two things this record deliberately does not state. Dakota publishes no cycle count tied to a depth of discharge, so no cycle-life figure is recorded even though a 5,000-cycle claim appears on the page. And Dakota publishes a single combined operating-temperature range rather than separate charge and discharge windows, so neither is recorded: on a heated battery the charge window is the entire point, and splitting one figure into two would invent a distinction the manufacturer never made.
Variant note: Dakota Lithium's 12V 100Ah deep-cycle battery as currently sold, which is the HEATED version (page title: 'Dakota Lithium 12V 100Ah Deep Cycle Heated LiFePO4 Battery'). Dakota appears to have consolidated the line: a sweep of their 12 V category found only this 100 Ah deep-cycle handle plus a CAN Bus sibling, with no non-heated 100 Ah still listed. This matters because the widely circulated older Dakota 100 Ah specification (about 31.9 lb, Group 27, 2,000 cycles) belongs to a different, discontinued product and is still shown on many third-party pages. Do not merge the two.
Data note: All figures taken from Dakota Lithium's official product page on 2026-08-15 (SKU PID12V100AhG24B). Weight and dimensions are published in metric directly ('Weight: 27.55 lbs (12.5Kg)'; '10.23in L x 6.60in W x 8.66in H (260mm x 169mm x 215mm)'), so neither is a conversion. cycleLifeCycles and cycleLifeDoDPercent are BOTH null on purpose: Dakota's claim is 'Up to 80% capacity for 5,000 cycles in recommended conditions', where 80% is end-of-life capacity retention rather than depth of discharge. Reading that as '5,000 cycles at 80% DoD' would fabricate a rating the manufacturer does not make. chargeTempRangeC and dischargeTempRangeC are both null because Dakota publishes only one combined figure ('Operating temperature: -4F to 140F (-20C to 60C) optimal operating temps'); splitting it would invent a charge-versus-discharge distinction the source never draws, which matters more here than usual because this is a heated battery. bmsRatingA is null: the BMS is described qualitatively (cell balancing, low and high voltage cutoff, short circuit, high temperature) with no current figure. terminalTorque is stored in the published unit only ('Max torque 15 ft. lbs.'); no newton-metre equivalent is published. maxInSeries and maxInParallel are null: the page says only that 12 V batteries 'can be used in series for up to 48V systems', and deriving a count from that phrase would be arithmetic on marketing copy. The product was listed out of stock on the official store when checked; that is an availability observation, not a release status, so releaseStatus remains current and the merchant availability is left unknown rather than recording a value that goes stale.
Specifications
Chemistry, nominal voltage, rated capacity and weight come from official manufacturer sources;
the exact claims and links are in the provenance table. Peak
(surge) discharge is always shown with the seconds it is rated for and is never presented as the
continuous rating, and any cycle-life figure is shown with the depth of discharge it is quoted
at. Figures the manufacturer does not publish are left blank rather than estimated.

Cycle-life test conditions
Dakota publishes 'Up to 80% capacity for 5,000 cycles in recommended conditions'. The 80% there is capacity retention at end of life, not a depth of discharge, so this does not meet the index's requirement that a cycle count carry its DoD basis and no cycle-life figure is recorded.

Strengths and weaknesses
Strengths
Integrated heating element warms the cells before charging below 0 C, so it can be charged in freezing conditions
11-year warranty, the longest of any battery in this index
Publishes rated energy directly (1,280 Wh) and its weight in kilograms rather than imperial only
200 A surge published with its 10-second basis, a longer window than most packs here
Weaknesses
No cycle-life figure can be published here: Dakota's 5,000-cycle claim is tied to capacity retention, not to a depth of discharge
No separate charge and discharge temperature ranges are published, only one combined operating range, which is a notable gap on a heated battery
No IP rating published anywhere on the official page
50 A maximum charge current, half the 100 A that several 100 Ah packs here accept
12.5 kg is heavier than the LiTime and Renogy 100 Ah packs indexed here
No charge controller or inverter included: it is a storage component, not a power supply

Retail offers — a commerce layer, not a source for any specification on this page.
No current price is tracked for this product; check the merchant for pricing.
Core specifications come from official manufacturer sources only, with the exact claim text
preserved per field. Spec sheets and manuals outrank marketing copy. See the
methodology for the full policy.
Internal Even-Heat Technology: When the battery is charged in temperatures below 0 C (32 F), the internal heating element warms the cells to 5 C (41 F)
