Hi,
The Shimano BT-EN805, BT-EN805-L, and BT-EN806 mainly differ in capacity and intended use.
The BT-EN805 and BT-EN805-L both offer 504 Wh, with the BT-EN805-L being optimized for mountain biking with better weight distribution. The BT-EN806, with its 630 Wh capacity, is designed for longer rides but comes with added weight.
All three are compatible with the same Shimano STEPS systems (EP8, EP6), making upgrades or swaps straightforward.
In short, if range is your priority, go for the BT-EN806. For more balanced or MTB-specific needs, the BT-EN805 models are more suitable.
Buying a second battery as a backup might seem smart, but keep in mind that even if it’s not used, it will still degrade over time. Lithium-ion batteries naturally lose capacity due to chemical aging, regardless of whether they’re actively in use. So, a stored spare battery won’t hold its original capacity forever, meaning you could still see diminished performance when you finally start using it.
I hope that helps clear things up! Happy riding and take care!

Hi...my 2023 Marin Alpine E2 has a Gen2 BT-EN806 battery in it and I'm wondering if i can get a BT-E8036 as a spare for all day sessions at the bike park? I'm seeing the older BT-E8036 online for £330 so pretty good price, but only if it works in my bike and powers the EP801 drive unit without errors. What do you think? ThanksHi,
