SLA Charger

hi,

is there any circuits/schematics for an SLA battery charger that can deliver 3 amps or more (max 5 amps) at 14.4 to 15 volts? all i seem to be able to find are ones delivering up to 1 amp or less.

ta

Just use the LM350 instead of the LM317 as it can supply more current.

Is the Lead Acid Battery Charger also compatible for Sealed Lead Acid Battery's, and what amount of current will it give out? or will it give out the current i put in (3 amps)?

What is the ampere rating of your generator? Is it a wind generator?
What is the wattage of your solar panel?
Why did you start a new thread?

around .5 amps (it's more like a dynamo)
2 watts
i was looking for a boost converter, although when i started the thread, i didn't know of the exsistance.
there is also the fact that i am using this to power a PWM motor controller, which has rheostatic braking (if i remember correctly, it will also put power back in)

i found this, same as the other one, but with float function: **broken link removed**

i i use this, then it will enable me to use a 'shore supply' (a disconnect-able transformer unit powered by mains supply, when there is no sun or not in use due to rain or other reasons).

All you need is a shunt regulator:

everything in the whole project (which the charger is part of) is protected. the battery output lines (BP and BN) have a 1 Pole + Neutral MCD, and the charger input has a Singal Pole MCD. they are all 16 amp types. i may add more batteries in series though, so i need to have a charger for the batteries i trust.
