Sell your GivEnergy 2.6 kWh battery
The GivEnergy 2.6 kWh battery is the smallest of GivEnergy's low-voltage packs, a Gen 1 unit 299 mm tall that weighs 35.5 kg. We buy it singly or several at once. If our written offer suits you, we send our engineer to disconnect it, and the pick-up, wherever you are in mainland England and Wales, is free.

How a 2.6 compares with a 5.2
- The smallest GivEnergy pack, 299 mm tall and 35.5 kg.
- No breaker on the pack. A separate 100 A DC breaker sits on the wall beside it.
- Battery firmware in the app starts 30 (for example 3022).
The 5.2 behind it is the next Gen 1 size up, at 515 mm. The two share a 480 mm width, so on the wall it's the height that gives a 2.6 away.
GivEnergy's part code for it is GIV-BAT 2.6. If measuring is awkward, photograph the label for us instead.
Inverters a 2.6 can run on
| Inverter | Works with a 2.6? | Notes |
|---|---|---|
| Hybrid inverter (Gen 1) | Yes | With a separate 100 A DC breaker. |
| Hybrid inverter (Gen 2) | Yes | With a separate 100 A DC breaker. |
| Hybrid inverter (Gen 3) | Yes | Ring terminals and a DC breaker of at least 100 A. |
| AC Coupled inverter 3.0 kW | Yes | |
| All in One | No | GivEnergy doesn't list it. The All in One runs its own 307 V battery. |
| All in One 2 | No | GivEnergy doesn't list it. The All in One 2 runs its own 307 V battery. |
Up to five packs can share one inverter, so yours may sit beside other 2.6s or bigger packs.
Mixing it with a Gen 3 pack brings in rules on battery firmware and on which pack is the master.
Collecting a 2.6
At 35.5 kg it's the lightest low-voltage pack, about a third of a 9.5 Gen 2's weight.
Our engineer still isolates the system before the pack is moved.
Six things we weigh up for a 2.6
We don't publish a price list. A small pack is judged on its health and cycle count first, like any other.
State of health
The battery management system records how much of its original capacity is left. For most packs it's the figure that matters most.
Cycle count
A high count is fine if the pack's health is good.
Generation and size
A 9.5 kWh Gen 3 pack is worth more than a 2.6 Gen 1. The rating label tells us which you have.
Cell balance
How closely the cells match. If they're far apart, the pack needs work before anyone can use it again.
A matched set
Packs of one generation that have run together are more useful to the next owner than odd ones.
Where it's been fitted
A garage or a loft is kinder than an outside wall. If the terminals or casing are weathered, say so on the form.
If the app shows its state of health, copy the figure into your answers.
Count your 2.6s on the form
Pick how many packs you've got, and each row starts as a "2.6".
What's a used GivEnergy 2.6 kWh battery worth?
As with every pack we buy, we start from how healthy it is and how many times it has cycled. It's the smallest GivEnergy pack, and a Gen 1 one, so it starts lower than the bigger and newer packs. We don't publish a price list. Tell us about yours and you'll get a written offer by email. If the 2.6 is working, its figures are read remotely before we collect it.
Before we collect
- For a working battery, we email you a link to a small app. You run it on a computer on the same network as your system.
- Then we run a state-of-charge calibration from our end. It reads each cell and tells us the battery's state of health and cycle count.
- If the kit differs from your description, on the check or on the day, we may requote or withdraw our offer, and you're free to walk away at no cost.
Please don't take it off the wall yourself
A low-voltage GivEnergy pack runs at 51.2 V DC with real fault current behind it. A high-voltage stack runs well above that, and an All in One at around 307 V. Our engineer isolates the system before anything is moved. If your installer has already disconnected it, say so on the form.

The bigger Gen 1 packs
Selling a 2.6
Do you buy the GivEnergy 2.6 kWh battery?
Yes. Every one of GivEnergy's six low-voltage packs is on our list, and the 2.6 is the smallest of them. Pick "2.6" on the form, and if you have several, add them all.
How big is a GivEnergy 2.6 kWh battery?
299 mm tall, 480 mm wide and 205 mm deep, and 35.5 kg, by GivEnergy's current datasheet. Older training manuals put it at 30 kg. There's no breaker in the pack itself, and a separate DC breaker is fixed to the wall next to it.
What depth of discharge does the GivEnergy 2.6 kWh battery have?
80% by GivEnergy's current datasheet, the share of its 2.6 kWh it's set to use. The 2022 training manual and a sheet from May 2022 say 90%, so older paperwork may show that instead.
