What's new in Gen 3? The BMS module's firmware can now be updated right from your phone! This way, you can keep up with the latest tweaks of the fast-paced lithium battery technology evolution in 1, 2, 5 and 10 years with that same battery!

2024 is the year where picking a lithium battery over lead-acid has become a NO-BRAINER! With cutting edge engineering, an 8 year warranty program and fantastic customer support, a lithium battery from REE is the best choice to get you going.

The 100Ah model is perfect for small camper systems. It is enough for most traditional applications like heaters, coolers, laptops, phones as well as occasional power tools and induction cooking surfaces. For a regular use or induction cooking surfaces, have a look at our 200Ah batteries. 

The self-heating system only uses energy received from the charger and does not use the battery's power. It is engaged when the battery is receiving current and the internal temperature is below 0°C. The cells will only start charging when they reach 0°C.

Batteries are individually tested for charging, discharging, self-heating and every security feature!

Internal self-heating

Canadian winters are nothing to mess with! All REE Solar batteries are equipped with internal self-heating to ensure operability even in the harshest conditions.

Heating pads are installed on the battery cells and will use incoming energy from the charging source to generate heat. Energy from the battery is never used to heat up the cells.

8 year warranty

Our products are tested to withstand almost everything, but hey, life happens. Our rock-solid 8 year warranty on batteries means you can go out and enjoy: we'll take care of the rest.

Warranty Information

Bluetooth connectivity

You don't have to get out of bed (or back into your van) to check the state of charge of your batteries. Just connect to them using our proprietary app to see the rate of charge, discharge, temperature, individual cell voltages etc. Just look for REE Solar on the App Store.

A few questions we often get

Collapsible content

I want to get a solar system for my camper/home: where do I start?

90% of our customers end up with one of our kits: they are versatile, balanced and cost-efficient. If you still think you might want to customize certains aspects of your system, the easiest way is to call or email us!

I see your prices are lower than most other brands, why is that so?

There are a couple reasons. REE is an extremely lean business: our team does everything in-house. That includes design, engineering, storage, handling, social media mgmt, taxes, BD etc. We don't hire expensive external consultant like most other companies. We also work directly with the largest factories and research centers in the world to ensure the best consistency and reliability while cutting out the middle man. On top of that, we barely run any ads anywhere and rely on word-of-mouth diffusion to grow our business, which has worked well for us so far.
