I. am at the stage where I am almost ready to pull the trigger and buy some batteries to make my 36v lead acid Cityel into a lifepo4 Cityel ..

so do i stick to 36v (no) I know I need to get to 40v or more ..

I am worried about buying big ticket items from over seas I have never used before ..

what else do I need to do to my cityel to make it cope with my new power pack.

and chargers ????

please help!

Hi Mark,
you can surely stay by your 36 volt compartment or you can convert to a higher voltage level like 48v. The second choice needs to have several changes to your CityEL, cause some parts rely on 36 volt and cannot stand 48v. Never did that by myself, but someone here surely did.

Also Leute, was muss alles geaendert werden, wenn man von 36 auf 48 Volt wechselt? Macht mal dem Mark ne Liste.

Viele Gruesse aus dem Saarland, Sascha

Hi,

hier steht:


DC-DC Wandler
Scheibenwischer
Schütze
Curtis, wenns ein alter ist.

Sonst was?

English Version:

You have to change the DC-DC, the Wiper, the big Relais for Direction Change and the Curtis Engine Regulator (if it is an old one).

DCDC: Change dthe protection Diode at the Input to one that can block 60V+

The Wiper needs a Pre-Resistor 6-12 Ohm, 12 Watt and at the Relais-Print change R7 (10 Ohm, 5 W) to 22 Ohm, 5 W for correct wiper park position.

The big Relais for direction change need a pre-resistor 25 Ohm, 6 W.

For changiong the Curtis i have no Informations.

Anything else?

I changed to 13 LFP cells and changed nothing! Except the charger, that now is a Meanwell RSP1500-48 with modifications to get reverse current flow protection ("active Mosfet rectifier"), a current limitation and a lower output voltage.

13 Cells are approx. 40V, that work with original Design. 16 Cells (48V) would be to much...
