24V (25.6 V nominal) 100 Ah self-heating LiFePO4 battery, 20.5 kg, rated 100 A continuous charge and discharge with a 300 A 5-second surge and 5,000 cycles at 80% depth of discharge. Self-heating lets it charge down to -20 C, and it is the first 24 V entity in this index.
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 Renogy's Core LT 25.6V 100Ah battery, the self-heating low-temperature member of the Core line and the first 24 V battery indexed here. It is rated 100 Ah at 0.5C and 25 C, at a 25.6 V nominal (eight LiFePO4 cells in series). Its battery management system holds continuous charge and discharge to 100 A each and allows a 300 A surge for 5 seconds. Renogy rates it for 5,000 cycles at 80% depth of discharge. The distinguishing feature is the integrated heating function: where a standard LiFePO4 pack must refuse charge below freezing, this one publishes a charge range down to -20 C, which is what the LT designation denotes and what separates it from the non-heated Core batteries also indexed here. It weighs 20.5 kg in a 522 mm case, carries an IP65 rating and M8 terminals torqued to 10 to 12 N m, and can be wired up to two in series and eight in parallel, giving a 48 V ceiling. It ships no charge controller or inverter.
Variant note: Core LT (Low Temperature) Series 25.6V 100Ah, SKU RBT24100LFPSH, the self-heating variant. Distinct from Renogy's non-heated 24 V Core batteries and from the 12 V Core, Core Mini and Pro lines also indexed here. The page's marketing title says 'Core Series' while the SKU and manual say Core LT; the LT designation and the self-heating row are the discriminators.
Data note: Figures taken from Renogy's published Specifications block and the official Core LT series manual on 2026-08-15 (SKU RBT24100LFPSH). IDENTITY: Renogy markets this page as the '24V 100Ah Core Series' battery, but the SKU and the manual both identify it as the Core LT (Low Temperature) Series at 25.6 V, and the self-heating function is what the LT denotes. The record is titled Core LT accordingly so it cannot be confused with a non-heated 24 V Core battery. releaseStatus is 'unclear' rather than 'current' or 'discontinued': the SKU appears to be delisted from the storefront (the product-detail gallery is gone and only a static page remains), but Renogy publishes no discontinuation statement, so neither status can be asserted. usableDoDPercent is null: 100% DoD appears only in introductory marketing prose comparing the battery to lead-acid, not in the Specifications block, and the manual's own spec basis is 80% DoD with a 20.0 V to 29.2 V range. Recording it would have promoted marketing copy to a specification. capacityWh is null because no watt-hour figure is published; 100 Ah at 25.6 V would be about 2,560 Wh but that is a computed figure, not a manufacturer spec. bmsRatingA, bciGroupSize, bluetoothMonitoring and warrantyYears are all null because the page publishes none of them. lowTempChargingCutoff is null rather than false: the battery charges below freezing via self-heating, but Renogy does not state the cutoff mechanism, so no claim is made either way.
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.

Use cases
24 V RV, marine or off-grid systems, where a single 24 V battery replaces two 12 V units wired in series
Cold-climate installs: the self-heating function publishes a charge range down to -20 C, where a standard LiFePO4 pack must refuse charge below 0 C
Building a 48 V bank by wiring two in series, or a larger 24 V bank with up to eight in parallel
Strengths and weaknesses
Strengths
Self-heating, with a published charge range down to -20 C rather than the 0 C floor of every other lithium battery in this index
The only 24 V entity indexed here, so it serves systems the 12 V records cannot
5,000 cycles published with its 80% depth-of-discharge basis and a stated 0.5C, 25 C test condition
300 A surge published with its 5-second duration, and 100 A continuous both ways
IP65 with a published terminal torque specification
Weaknesses
Release status is unclear: the SKU appears to be delisted from Renogy's storefront and the product now resolves to a static page rather than a live listing, so availability should be checked before relying on it
20.5 kg, and a 522 mm case that needs a purpose-built tray rather than a standard BCI group size (none is published)
Renogy publishes no warranty term, no rated watt-hour figure and no BMS current rating on this page
Only two may be wired in series, capping a series string at 48 V
No charge controller or inverter included: it is a storage component, not a power supply
