Battery Adapter for Makita 18V Battery, ETOOLAB Adapter for Power Wheels with LED Ammeter Voltage Display, Fuses & Wire Terminal Battery Adapter 14 AWG Battery Converter for DIY (1 Pack)

Using a fan or any 12v product with the cigarette port (bought separately) connected to this. Easy connection to swap out batteries and it been good so far over 2 months

Might not be accurate to the 10th decimal.But very practical & informative for the price & intended use .

Everything worked like it should, arrived on time, and there were very clear instructions on how to wire to your power wheels or other devices. There was plenty of hardware with extra shrink wrap. I seriously don’t know how they’re making money on these

I bought several of these to use battery packs to power other devices, make custom devices and give life to old stuff.1) Old jump starter pack that had compressor and AC inverter got a new lease on life. Removed heavy lead acid battery and installed pack on front with DC to DC bridge (bring down 19-40 volts to 12 volts) and put clip on front of pack. See image2) Used project box, DC/DC bridge and outlet plugs to make portable cigarette lighter plugs and USB that runs off of battery pack. I have portable power for all kinds of devices and electric car jacks.3) Kids ride on toys - straight forward power conversionThe downside is that the cord location and that of the display makes it hard to conceal without major modifications. Overall it works well and is cheap, but simple connector location changes would make it easier to add to more devices.It should be bundled with a DC/DC bridge to get it to the correct power for your application.

I have many Makita and Makita-style batteries and I've been itching to power a project using besides my tools using these batteries. A 36V mid-motor bike perhaps? An adult-sized, electric big wheel or green machine? The possibilities are endless. Got the batteries, got the socket for hot-swapping batteries, just need a donor machine and a motor and a controller and a bunch of other stuff. Well, that got real now that I hear it out loud. Sounds like it could get expensive. A cheaper option might be adding 3 Makita batteries in series to the 48V ebike I already have and see how she rolls with 54V, That would be cheap and easy. Great, it's a plan. Thanks for hearing me out.

This battery adapter is well made and is constructed of quality materials and thick wire. It works perfectly on my Makita style batteries. The on-off switch is a nice feature not offered on all of these types of adapters. I do wish they left a little extra wire length to allow for easier mounting is the meter.

I used this to adapt an old NiCd powered drill from Walmart to work with my Makita Li batteries. The adapter included some extra components (rocker switch, fuse holder &fuses, volt/amp meter) I didn't need but they will be useful for a future project.
