WARNING – BATTERY DAMAGE RISK
This e‑bike kit does not provide cell‑level battery management. Using cordless drill batteries to power an e‑bike can permanently damage the batteries if they are allowed to fully discharge.

Always monitor your battery level and DO NOT run packs until the bike stops. Check the battery’s fuel‑gauge or meter regularly and swap/recharge as soon as power noticeably drops or the indicator shows low.

Some original Ryobi 18V lithium batteries include low‑voltage cutoff inside the pack, so they stop delivering power when the cells get too low. However, when used outside Ryobi tools, this protection may not behave as intended, and you should still avoid deep discharge.
Milwaukee M18 and DeWalt 18V/20V Max packs have a battery management circuit that monitors cell voltage and temperature, but in normal tool use the tool and battery cooperate to decide when to shut down; they are NOT designed to protect the battery when used on third‑party devices like e‑bikes. Many generic/knock‑off packs may have minimal or no effective low‑voltage protection, making them especially easy to over‑discharge and permanently damage.
