KBT 36V 5Ah Rechargeable Li-ion Battery Pack, with Charger, Charging Cable, Cable Connector, Build-in 10A BMS
Quick take
This 36V 5Ah Li-ion battery pack is designed as a replacement or DIY power source, bundled with a charger, charging cables, and multiple connectors. It includes a built-in 10A BMS protection PCB for overcharge, over-discharge, over-current, and short-circuit protection. The buying caveat is compatibility, especially with battery bay dimensions and connector fit, and delivery timing can vary by order.
Pros and cons
Pros
- Comes as a set with charger and several cable/connector options (includes XT-60, XT-30, and T-plug cables).
- Built-in BMS protection PCB for key safety protections (overcharge, over-discharge, over-current, short circuit).
- 36V 5Ah capacity in a compact battery footprint, plus short battery and charger cable lengths are specified.
- Buyer feedback mentions easy installation and good performance for scooter and DIY projects.
Cons
- Limited review volume, so buyer-review evidence is too limited to confirm long-term performance trends.
- Fit can be tight depending on the enclosure, so double-check dimensions before ordering.
- Some buyers reported shipment delays for certain orders, which may affect project timelines.
What buyers think
Buyer-review evidence is limited (18 ratings total), but the recurring themes are straightforward. Several buyers report the battery works well for 36V e-scooters and that the installation process was manageable. A few also mention it performed as expected for DIY builds and custom projects, and that charging worked well. There is not enough evidence to confidently generalize about long-term battery health, but the available feedback does suggest the set is practical for users who want an off-the-shelf battery plus charger and connectors.
What you’re getting (set contents)
This battery pack is bundled as a battery and charger set, not just a bare pack. In the box you should expect:
- 1x 36V 5Ah Li-ion replacement battery pack
- 1x charger
- 1x cable connector
- XT-60 cable, XT-30 cable, and a T-plug cable (for different project harnesses)
Key specifications that matter for compatibility
- Battery voltage: 36V (DC)
- Capacity: 5000 mAh (5Ah)
- Battery dimensions: 115 x 76 x 50 mm
- Battery cable length: 180 mm
- Charger cable length: 90 cm
- BMS: built-in 10A BMS protection PCB
- Weight: about 1 kg
Performance and charging expectations
The set is marketed as a ternary Li-ion pack with good charge-discharge behavior and low self-discharge. It also includes a BMS intended to help guard against common failure modes such as overcharge, over-discharge, over-current, and short circuits. For buyers comparing battery types, a practical takeaway is that Li-ion packs generally aim for better cycle life than older lead-acid options, but review evidence here is not detailed enough to confirm real-world cycle counts for your exact use case.
Pros and cons for common use cases
Best for
- 36V e-scooter owners who need a replacement battery set and want multiple connector options included.
- DIY electronics projects where you can match the 36V requirement and work with the provided harness connectors.
- Shoppers who prefer a bundled charger instead of sourcing a separate charging solution.
Who should be careful or consider alternatives
- Measure your compartment against the stated battery dimensions.
- Buyers who need predictable delivery timing, since some reviews mention shipment delays.
- Those looking for proven long-term battery health data, because review evidence is limited and does not provide enough detail to establish lifespan expectations for your scenario.
Price and availability
The list price shown is higher than the current price, and availability is listed as in stock. Since pricing can change frequently, check the latest cost before committing. Buy on Amazon.
Alternatives to consider (by buyer priority)
If you are comparing options, choose alternatives based on your biggest constraints:
- If you need a different voltage: look for a battery pack that matches your device rating exactly (voltage mismatch can cause poor performance or damage).
- If you need different connectors: prioritize packs that explicitly match your harness or include the connector type you use.
- If space is tight: compare battery dimensions and cable lengths, not just capacity.
- If you need a higher current draw: the included BMS is rated at 10A, so review your device’s current requirements before buying.
Bottom line
The KBT 36V 5Ah Li-ion battery pack is a practical, bundled option for 36V scooter replacements and DIY builds that benefit from included charger and multiple connectors. The main things to verify are enclosure fit (dimensions), connector compatibility, and whether your use case aligns with the BMS protection rating. With limited but positive buyer feedback on installation and charging, it can be a reasonable pick if you match the electrical and physical requirements.
FAQs
Will this battery work with my 36V device?
It is designed for 36V (DC) systems and provides a 36V output with a 5Ah capacity. You still need to confirm connector compatibility and that the device’s current draw fits the pack’s BMS protection rating (10A).
What is included in the box?
You should receive the 36V 5Ah Li-ion battery pack, a charger, a cable connector, and multiple cable/connector options including XT-60, XT-30, and a T-plug cable.
How big is the battery pack?
The battery footprint is 115 x 76 x 50 mm (L x W x T). If your enclosure is tight, measure your compartment to avoid fit issues.
How long are the battery and charger cables?
The battery cable length is 180 mm, and the charger cable length is 90 cm.
Is there reliable evidence of long-term lifespan?
Buyer-review evidence is limited, so it is not possible to confirm long-term cycle-life performance for your exact use case from the reviews alone. The pack includes BMS protection intended to help with common electrical risks.
