25.6V 200Ah 24V Motorhome Energy Storage Bank 5120Wh MPPT Solar Charging 100A Deep Cycle

25.6V 200Ah 24V Motorhome Energy Storage Bank 5120Wh MPPT Solar Charging 100A Deep Cycle

Large motorhomes and serious van conversions increasingly run 24V systems because halving the current halves cable losses and lets owners use thinner, cheaper wiring. This 25.6V 200Ah LiFePO4 battery delivers 5120Wh of usable energy for exactly those builds, replacing the two series-wired 12V batteries that older 24V installations relied on.

The pack combines a 100A continuous BMS, Grade-A cells rated for 6000 cycles, and a case sized for common RV battery bays. It connects directly to 24V MPPT solar controllers, 24V inverter-chargers and DC-DC chargers, which makes it the straightforward choice when you are building a 24V power system from scratch or upgrading an existing one.

Native 24V Architecture
Running the house system at 24V instead of 12V halves the current for any given load. A 2000W inverter draws about 83A at 24V compared with 167A at 12V, which means the same power over smaller cables with lower voltage drop. Components also run cooler and fuses can be sized smaller. This battery is built around that architecture with an 8-series cell configuration that produces a native 25.6V nominal voltage.

5120Wh of Usable Energy
At 200Ah and 25.6V, the pack stores 5120Wh - the equivalent of four typical 12V 100Ah lithium batteries - in a single box. That is enough to run a 3000W inverter for about an hour and a half at full load, a 13.5K BTU roof air conditioner for four to five hours, or a full residential fridge plus lighting and electronics for two days. For most motorhomes, one pack covers the entire house load profile.

100A Continuous BMS
The 100A continuous rating provides 2560W of sustained 24V power, which comfortably feeds a 2000W inverter and handles most simultaneous loads in a motorhome. Peak current of 200A covers inverter surge and motor startup. The BMS balances all eight cell groups during charging, protecting the series string from the imbalance issues that plague series-wired 12V batteries.

Built for 24V Solar and Charging
Most 24V MPPT controllers and inverter-chargers work with this battery out of the box. Set the absorption voltage to 29.2V and float to 27.6V, values that match the LiFePO4 presets on Victron, EPEver, Renogy and Growatt equipment. The 60A recommended charge current accepts full output from 800-1000W of solar panels, so a sunny day recovers a meaningful share of the pack's capacity.

Why 24V Makes Sense for Larger RVs
The physics is simple: power equals voltage times current, so doubling the voltage halves the current. Halving the current cuts resistive losses to a quarter for the same cable, or lets you use smaller cable for the same loss. In a 30-foot motorhome the cable runs from the battery bay to the inverter can exceed 5 meters; at 12V and 2000W that means heavy 4/0 cable, while at 24V the same run uses 2 AWG with better efficiency. Solar arrays above 800W also favor 24V controllers, which handle the higher input voltage with less loss. For new builds and major upgrades, 24V is the pragmatic middle ground between legacy 12V and full 48V systems.

Typical 24V Installation Scenarios
This pack is the natural fit for 24V motorhomes, large camper vans with high solar capacity, overland trucks with 24V electrical systems, and small off-grid cabins running 24V inverters. It also suits commercial vehicle conversions - ambulances, mobile workshops and service trucks - that standardize on 24V chassis electrics. When paired with a 24V-to-12V DC-DC converter, owners can keep legacy 12V appliances without compromising the main system's efficiency.

6000-Cycle Long-Life Cells
The 8-series Grade-A cells are rated for 6000 cycles at 80% depth of discharge, which is roughly 16 years of daily cycling or a lifetime of weekend use for most owners. Because the battery is never series-parallel mixed with other packs in a single string, cell matching stays consistent and the BMS can balance precisely, protecting that long life in real installations.

Simpler, Lighter Installation
Replacing two 12V 200Ah batteries wired in series with this single pack removes inter-battery cables, simplifies the fuse layout and saves about 15kg of weight. The 520 by 269 by 240 millimeter case fits standard RV battery bays, and the 42kg weight is manageable with two people or a small lift. Fewer connections also means fewer places for corrosion and loose terminals to develop.

Options for System Integrators
An optional RS485 or CAN port exposes BMS telemetry to compatible monitoring systems and inverter-chargers, which is valuable for premium motorhome builds and fleet operators. WNRLN provides the communication protocol to qualified partners, along with OEM branding, custom packaging and full compliance documentation for vehicle integration.

Frequently Asked Questions

Q: Can I use two of these in parallel for a 24V 400Ah bank?

A: Yes. Up to four packs can be paralleled for 800Ah / 20.48kWh. Connect each pack to a common positive and negative busbar with equal-length cables, and fit a fuse per pack. Each pack's BMS manages its own cells, and the parallel bank shares load automatically.

Q: What size solar array do I need to recharge it?

A: A 1000W array with a 60A MPPT controller can return about 40-50% of the pack's capacity on a good sunny day. For full off-grid recovery, 1500-2000W of panels or a combination of solar and alternator charging keeps the bank topped up during active travel seasons.

Q: Is this battery compatible with my 12V appliances?

A: It powers 24V loads directly. For 12V appliances, add a 24V-to-12V DC-DC converter sized for your total 12V load. This is standard practice in 24V builds and is more efficient than running the whole house on 12V.

Q: Does the optional CAN port work with my inverter?

A: The CAN port uses the standard lithium battery communication protocols supported by major inverter-charger brands such as Victron and Growatt. Send us your inverter model and we will confirm protocol compatibility and provide the correct wiring guide before you order.
