Description
52V 24Ah Downtube E-Bike Battery – Lithium Battery Pack for Electric Bike Conversion Kits
The 52V 24Ah downtube battery is the ideal choice for riders who want long range in a compact format, mounted on the bicycle's frame tube. The 24Ah capacity (about 1248Wh) provides the energy needed for the MTX kits of 1000W, 1500W, 2000W and 3000W, and suits daily commuting, long routes and intensive use.
The downtube design is made for mounting on the horizontal or diagonal tube of the frame, giving a compact, integrated look. The battery locks onto a mounting plate with a key lock system, which gives it extra protection against theft and stability during use.

Why the 14S configuration matters for range
The 14S configuration means 14 cells connected in series, each contributing about 3.6–4.2V to the total pack voltage. Combined with a large 24Ah capacity, this architecture offers one of the best range-to-weight ratios in the 52V line, and suits riders who cover long distances without wanting a triangle battery.
BMS and cell protection
The battery has a 30–40A BMS, built with premium LG/EVE/Samsung cells, which monitors in real time the voltage of each cell, the temperature and the operating current, preventing overcharge, excessive discharge and imbalance between cells. The casing is IP65 certified, protecting against light rain and splashes in normal use.
Which Kits It Is Optional On
MTX kits of 1000W, 1500W, 2000W and 3000W
Long range for daily commuting and long routes, in a compact format mounted directly on the frame.
Mid-Drive Conversions
Compatible with most medium-power mid-drive systems, ideal for trekking and intensive urban use.
High-Range DIY Projects
The 24Ah capacity gives extra distance over the standard 17.5–20Ah variants, without needing a triangle battery.
Installation, Maintenance and Safety
Mounting Steps
- Choose the mounting plate that matches the thickness of the diagonal tube and fix it firmly
- Slide the 6–7 kg battery on until the key lock system engages firmly
- Connect the XT60 connector, making sure both plugs are fully inserted
- With the largest capacity in the downtube range, check the level LEDs before long routes
Maintenance
- With 24Ah capacity, you have more flexibility before you need to recharge below 20%
- For breaks of over a month, check the level periodically and recharge to 40–60% if it has dropped too far
- Because of the large capacity, a full charge can take up to 5–7 hours — do not leave the charger unattended
- Avoid temperatures below 0°C or above 40°C, especially while charging
