Source for minimum 3.5 to 4 Amp Hour LiFeP04 charger

As the title says. Googling doesn't return much. I'm looking to buy a new Ebike with a 48 Volt, 12 AH LiFeP04 powered system. It comes with a measly 2 Ah charger. They want nearly $300 for a 4 Ah charger. That seems high. Would appreciate some sources for 4 Ah chargers that won't break the bank.

Check Ebay there is a US Seller offering a 48V 3 A High Quality metal case charger. 39.99 he has 10 to sell. Buy 2 and you have a 6A for 80.00 US. Plus free shipping in US. The Seller is Dasherdeals

BTW its amps for chargers, not amp hours. Best 48v charger I own came from EM3ev. He's got 5 or 6 amp chargers, with a nice three way switch for partial charging, or fully charging.

Not cheap, but no way $300.

Amps is adjustable on the charger, so it can be turned down if your bms won't support 5-6 amps.

i have some chargers but no way to know where you are located.
