🔋 High-Power 54.6V 3A Lithium Battery Charger for 48V 13s Batteries Pack with DC 5.5×2.1mm Plug and 5.5×2.5mm Tip Review

This charger works really well for recharging lithium batteries. It's compact, can charge up to 4 batteries at once, and comes with a safety feature that prevents overcharging. It's a handy accessory to have around the house for all your rechargeable lithium battery needs. One downside is that it only works with batteries that have a specific plug size, but most lithium batteries will work just fine. Overall, a great investment for a healthier and more eco-friendly household.

I use it to charge USCOOTERS/E-TWow Electric Scooter GT SE (Smart Edition) 48V Scooter charger shows a red LED while charging and then changes the LED color to green when charging is complete. It also turns off automatically after charging. The scooter will indicate that it is 100% charged.

Bought as a backup for my Smart Charger. Well charged battery 48V. It stopped charging about half a volt less than the advertised 54.6V, but so did my smart charger. Both the input and output cords are short enough that I either have to charge the battery on the bench or use an extension cord to charge the bike battery. The cables appear to be quite flimsy, but they seem to carry power well. The device works perfectly and the price is good, that's why I give 4 stars.
