SuperHandy 48V 4Ah Lithium-Ion Battery, 177.6Wh Rechargeable Power Pack - Compatible with 48V Snow Thrower, Mobility Scooter, Utility Cart, Wheelbarrow - Not for Capstan Winch (Battery Only)

Arrived mostly charged, is great for extending the use-time of the mobility scooter, plus we have two of the 2Ah batteries also. Being a Lithium-based battery, it's safest to not leave plugged into the charger or in a confined area. You want it to have plenty of free air to cool and circulate air. You don't want to rely on the BMS (battery management system) inside the battery or on the charger because if there is a failure of any kind Lithium battery explosions and fires are very destructive. Charge the battery to full and then unplug the battery from the charger.

The round prong on the charger you got with the wheelbarrow does not fit, the hole in the battery is too tight. You'll be forced to buy another charger (another $50) that can hook up to the flat connector on the battery.

They work, although , I wish they had genuine overcharge protection. Hard to say when they're fully charged, or overcharged. So as soon as the 4th light comes on, they come off the charger.

Batteries release energy way faster than they should.

Excelente producto y todo salio muy bien.

This battery is soooo powerful! It recharges quickly and holds a very long charge. I used it in my electric mobility scooter and could really tell the difference. It had more power! This battery is even better than described in the listing in my opinion. I highly recommend it. It's soo powerful that I might buy another one as a backup! Awesome battery at a great price!!!

This is advertised as fitting the mobility scooter, but it is too big to fit in the space even with trying to modify it. You just can’t get it to work.

Very good product
