Description
Capacity is not a number on a box. It is the difference between finishing the job and packing up early. The Jump 1500 Extra Battery is 1548 watt-hours of lithium iron phosphate storage that docks into a power station you already own: the JUMP 1500X, the JUMP 1800, the JUMP 2200. It is not a power station itself, and it will not run a kettle on its own. It is the second reservoir, the one you add after the first one turns out to have been a first draft.
Lithium iron phosphate is the chemistry you choose when the battery has to live in a van, a shed or a truck bed. LiFePO4 holds its structure through deep discharges that would age a lithium-ion pack, and it does not carry the thermal runaway profile that makes insurance inspectors ask questions. That is why this pack ships with CE, FCC, RoHS and UL certification rather than a sticker and a promise. Paired with the host station it delivers 1000 to 1500 watts of output, and it accepts up to 200 watts on the input side, which is a deliberate overnight fill rather than a fast top-up.
Geometry matters as much as chemistry. The case is 36 by 27 by 28 centimetres and weighs 14.87 kilograms, sized so one person can move it without a trolley and so it stacks beside the station instead of on top of it. Charging is rated from 0 to 55 degrees Celsius and discharge from -20 to 55, which means the pack can stay in the vehicle over a cold night and still be useful in the morning. Home energy, jobsite power and weekend off-grid work are all the same problem: you need more hours than the first battery had.
This is not a spare battery. It is the extension that turns a good afternoon into a completed project.
What Makes It Different
- ✦1548 Wh of LiFePO4 capacity that docks into the JUMP 1500X, JUMP 1800 and JUMP 2200 stations
- ✦Expansion module by design, so the station you already own keeps doing the inverting and the switching
- ✦Lithium iron phosphate chemistry rated for deep cycling and stable under sustained load
- ✦CE, FCC, RoHS and UL certified rather than self-declared
- ✦200 W maximum charging input for a steady overnight refill from solar or mains
- ✦1000 to 1500 W combined output when paired with its host power station
- ✦14.87 kg in a 36 x 27 x 28 cm case that one person can move and stack

Where It Earns Its Place
This is the module for the person who bought a 1500 watt-hour station, then discovered that a fridge, a laptop and a router run through the night faster than the marketing page suggested. It suits van conversions that need a second night of autonomy, cabin owners running lights and a pump through a storm outage, and photographers or crews charging batteries at a location with no hookup. Add it to the station you own rather than replacing a station that still works.
The EastSupplier Promise
Sourced directly from vetted manufacturing partners, inspected before dispatch, and priced without distributor layers. If the item arrives outside specification, we replace it or refund it. Every listing on this store is curated by a human buyer, not bulk-imported and abandoned.
Questions Buyers Actually Ask
Q: Can I use this battery on its own?
No. It is an expansion module and needs a JUMP 1500X, JUMP 1800 or JUMP 2200 to invert and distribute power. Buying it without the host station will not give you a working power supply.
Q: How long does a recharge take?
Plan for an overnight rather than a lunch break. The input ceiling is 200 W, so a full refill from empty is a deliberate, slow process, and that is intentional for pack life.
Q: Why LiFePO4 instead of a lighter chemistry?
Because cycle life and thermal stability matter more than the last few hundred grams. LiFePO4 tolerates deep discharge and holds up under repeated partial charging far better than a conventional lithium-ion pack.
Q: Can it stay in a cold vehicle?
Discharge is rated to -20 degrees Celsius and charging starts at 0 degrees, so the pack can spend a cold night in the vehicle as long as you let it come up to temperature before recharging it.
Q: How much extra runtime does it actually add?
It doubles the storage behind the same station. Whatever your station ran for on its own, it now runs for roughly twice as long, since the inverter and outputs have not changed.
