1. OEM-Matched Fit
Precision form factor delivering exact latch geometry, rail fit, and charger seating — the pack drops into host tools and chargers exactly like the original.
2. 18650 5S2P Architecture
A 5S2P cell string delivers the continuous and pulse current Makita brushless motors demand, holding a stable 21V rail without the voltage sag that degrades tool performance under load.

Frequently Asked by Distributors:
What is the MOQ for the CTQH1500 replacement battery?
The standard MOQ is 100 units for the CTQH1500. You can get paid samples of 1–10 units to check the BMS-handshake before placing an order. Private-label or custom-spec runs start at 500 units.
Is the CTQH1500 drop-in compatible with original Makita chargers?
Yes. The CTQH1500 BMS has model-specific software, so it works correctly with real Makita chargers. It reports the battery’s charge, checks that it’s real Makita, and prevents accidents by locking out the battery. This is the same as the original equipment manufacturer (OEM) pack. Handshake is validated on 100% of units at the end of the line.
Does the CTQH1500 use a proprietary mold?
This SKU uses a proven standard form factor (not an in-house mold). It is designed to fit and lock properly with the original equipment manufacturer (OEM) latch geometry.

The CTQH1500 uses high-quality 18650 cells (4000mAh each) arranged in a 5S2P configuration for a nominal 21V and a true rated capacity of 4.0Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
