Detailed overview: Dyness 24V 100Ah Lithium Battery 2560Wh
The Dyness 24V 100Ah LiFePO4 battery is a lithium iron phosphate battery rated at 2560Wh, built to replace two 12V 100Ah batteries wired in series in a 24V setup. Packed into a single 531 x 206 x 217 mm case, it cuts wiring in half and frees up close to 30% of space compared with a two-battery setup, a real plus in the tight battery bay of an RV, a boat or a converted van.
Unlike most raw batteries on the market, usually sold in 12V, this Dyness is one of the few references available in 24V: a useful step up for more powerful solar kits, 24V-wired boat or RV installations, or 24V trolling motors that need higher voltage for lower line losses. Made by Dyness, a brand better known for fixed residential energy storage, it is aimed at a slightly more technical audience than mainstream leisure batteries: installers, seasoned solar DIYers or boat owners used to sizing their own battery banks.
The built-in 100A BMS protects against overcharge, deep discharge, short circuits and overcurrent, with a supported surge of 300A/s to absorb the current draw when an electric motor starts up. Low-temperature protection automatically stops charging below 0 °C (resuming automatically at 5 °C) while still allowing safe discharge down to -20 °C, a genuine advantage for outdoor winter storage or mountain use. Built around A+ grade LiFePO4 cells, it is rated for over 4000 cycles at 100% depth of discharge, for a claimed 10-year lifespan backed by a 5-year manufacturer warranty.
This base version has neither Bluetooth nor Wi-Fi (Dyness offers a separate BT variant for remote monitoring): a deliberate trade-off that keeps the price well below rival 24V 100Ah LiFePO4 batteries of equal capacity. Rated IP65, it can be expanded up to 20.48kWh in a 4P2S setup (8 units, 51.2V 400Ah) to build a more ambitious solar storage system. A reliable, affordable base for anyone building a custom solar kit or 24V system.

Comparison
In the still-limited field of 24V 100Ah LiFePO4 batteries, the Dyness goes up against several direct rivals that show up in searches like "Dyness 24V 100Ah vs LiTime" or "Dyness vs Power Queen 24V": the LiTime 24V 100Ah, a long-standing reference in the nomadic power market; the Power Queen 24V 100Ah, already featured in our 12V lineup; and the Redodo 24V 100Ah, a recent and very active alternative in this segment. Here is how it stacks up against these three rivals, all at the same 2560Wh capacity.
| Criterion | Dyness 24V 100Ah | LiTime 24V 100Ah | Power Queen 24V 100Ah | Redodo 24V 100Ah |
|---|---|---|---|---|
| Capacity | 2560Wh | 2560Wh | 2560Wh | 2560Wh |
| BMS | 100A (300A/s surge) | 100A | 100A | 100A |
| Rated cycles | 4000+ (100% DoD) | 4000 to 15000 | 4000+ | 4000 to 15000 |
| Weight | 19.3 kg | ≈ 20.8 kg | ≈ 20.8 kg | ≈ 20.7 kg |
| Cold-weather protection | Yes (down to -20 °C) | Yes | Yes | Yes |
| Observed price | ≈ 300 € | ≈ 500 € | ≈ 437 € | ≈ 427 € |
At matching capacity and BMS output, the Dyness 24V 100Ah stands out mainly on price, roughly 30 to 40% below its three rivals on the French market where these prices were observed, and on a slightly lower weight, handy when carrying it into place. LiTime and Redodo advertise higher cycle counts on paper (up to 15000), but that figure usually applies to a partial depth of discharge rather than the 100% DoD Dyness rates for. For a solar kit or 24V system that does not need Bluetooth monitoring, the Dyness remains the most well-rounded choice for the best capacity-to-price ratio.

Our tester's review: Julien De Jurquet
We fitted this Dyness 24V 100Ah in place of two ageing 12V batteries wired in series inside a solar kit on a converted van, and the space saved is obvious straight away: one single block, two terminals, half the wiring. Mounted on a 24V trolling motor, it holds up through a full day on the water without flinching, even in cool weather. The 100A BMS copes well with the current draw at motor start-up, and the low-temperature protection is reassuring for outdoor winter storage. The one real downside: this base model has no Bluetooth, unlike the BT version in the range, so there is no way to track the state of charge from a phone, something a few buyers only notice after skimming the listing. Dyness support was responsive when another buyer ran into a delivery issue, which says something good about the brand. For the price, well under its direct rivals at the same capacity, it is a safe bet for anyone who does not need remote monitoring.
Frequently asked questions: Dyness 24V 100Ah Lithium Battery 2560Wh
No, this base version has no Bluetooth or Wi-Fi monitoring. Dyness sells a separate BT variant for remote monitoring, at a higher price.
Yes, that is its main use case: a single Dyness 24V 100Ah replaces two 12V 100Ah batteries in series, with half the wiring and about 30% more free space in the battery compartment.
Charging automatically stops below 0 °C (resuming at 5 °C) to protect the cells, while discharge remains safe down to -20 °C, a real plus for outdoor winter storage.
Yes, it is one of Dyness's recommended uses: the 100A BMS absorbs the current draw at start-up, with a supported surge of 300A/s. It is not designed to start an engine, though.
Yes, it supports a 4P2S setup with up to 8 units, for a 51.2V 400Ah (20.48kWh) system, ideal for a more ambitious home solar storage setup.
