Sell your GivEnergy 9.5 Gen 2 battery
The GivEnergy 9.5 Gen 2 (9.5 kWh) is the tallest of the low-voltage packs, 800 mm and 110 kg, with its DC breaker built in. We plan the lift before we turn up. Take our written offer and we'll disconnect it and collect it free across mainland England and Wales.

How to tell your 9.5 is a Gen 2
- The tallest pack, at 800 mm and 110 kg.
- A 100 A DC breaker built into the pack.
- One combined power-and-data plug.
- Two banks of DIP switches (ID and master/slave).
- Battery firmware in the app starts 30.
Next to it, shown to the same scale, is the newer 9.5 Gen 3. It holds the same 9.5 kWh in a case only 576 mm tall. The oldest datasheet we hold for the 9.5 Gen 2 is dated January 2022. There's no 9.5 Gen 1, whatever a listing says, so a 9.5 kWh pack that isn't a Gen 3 is this one.
GivEnergy's own documents disagree on how deep it is. We use the figure in the current 9.5 Gen 2 datasheet and the Gen 2 battery manual, 242 mm. The 2022 sheet has the 9.5 Gen 2 at 223 mm deep.
What a 9.5 Gen 2 works with
| Inverter | Works with a 9.5 Gen 2? | Notes |
|---|---|---|
| Hybrid inverter (Gen 1) | Yes | |
| Hybrid inverter (Gen 2) | Yes | |
| Hybrid inverter (Gen 3) | Yes | Combined cable; no separate breaker needed. |
| 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. |
Every inverter it works with is one we buy as well, so if yours is going too, the packs and the inverter can go on one form.
Selling a 9.5 Gen 2 and the inverter it ran on
Pick "Inverter and batteries" at the start of the form, and it asks which inverter you have before it gets to the packs. We price the inverter and each pack separately. Choose "Batteries" instead if the inverter is staying.
What we need to know to move a 110 kg pack
A garage with a level path to the drive is the easy case. A loft or an upstairs cupboard takes more planning, so send a photo of the way in with the form if you can.
You can also bring it to one of our bases, by appointment.
What we look at on a 9.5 Gen 2
We don't publish a price list. No low-voltage pack GivEnergy made holds more than a 9.5 Gen 2.
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.
One photo of the rating label and one screenshot from the app tell us most of what sets a used pack's value.
Tell us about your 9.5 Gen 2
Choose "Batteries", then add a "9.5 G2" tile for every pack you're selling.
What's a used GivEnergy 9.5 Gen 2 battery worth?
Mostly its health and its cycle count. It holds as much as a 9.5 Gen 3, which starts higher at the same health because it's the newer pack. We don't publish a price list. If you've seen its health figures in the app, put them on the form. Your written offer comes back by email. A working Gen 2 gets a remote check, cell by cell, 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 newer 9.5 kWh pack, and the 8.2
Selling a 9.5 Gen 2
How do I know my 9.5 is a Gen 2?
Measure it. A 9.5 Gen 2 stands 800 mm tall, the tallest of the low-voltage packs. On a Gen 2 the DC breaker is part of the pack, and one plug carries power and data together. Look for two banks of DIP switches as well. Its battery firmware in the app starts 30.
How do you take a 110 kg battery off the wall?
Our engineer isolates the system and disconnects the pack first. Then it comes off the wall and we carry it out. At 110 kg it's the heaviest low-voltage pack GivEnergy made, so tell us on the form where it's fitted and what's in the way, stairs or a tight doorway for example. We plan the lift from that before we come.
If I sell my Gen 2 packs, will my Gen 3 pack still work?
Yes. A Gen 3 pack works with the same hybrid and AC Coupled inverters a Gen 2 does, on its own or with other Gen 3 packs. While it shares an inverter with Gen 2 packs, every pack needs battery firmware from May 2024 or later, and the 5.12 Gen 3 manual makes the Gen 3 the master. Once only Gen 3 packs are left, neither rule applies.
