Alternative battery charger

[wehey]

Hiya all.
The charger i have with my 48v battery has a built in fan to keep it cool. The problem is that it doesn't allow for stealthy charging at work as its really noisy.
Is there an alternative available without a built in fan?
The spec of the battery are as follows
48V Capacity: 10.4Ah（25℃） over-discharge protection.
Size 34 x 12 x 8 cms
Weight 4.3±0.05kg
Standard discharge 10±0.5A
Maximum continuous discharge current 25±0.5A Discharge cut-off voltage ≥ 42V
Battery over-discharge protection
Charge voltage : 54.6±0.2V
Charge with matched charger
Standard charge 2±0.5 AResistance ≤150mΩ Between discharge port of positive and negative

Thanks in advance

It's a standard 13S Lithium battery charger (13 x 4.2v =54.6V). So you can use any one of about 2 to 2.5 amps. 2.5 amps is probably ideal. See this pne:

The charger d8veh pointed out has three options for a connector but not that one

Good news is it's very standard - you can pick one up from maplins, cut the wrong connector off and solder the right one on

I'm using this absolutely SILENT charger combo:

I needed it because my battery is 72V. I charge all cells to 4V everyday to enjoy years of battery calendar life !
